The Delta IV Medium+ (5,4) rocket is scheduled for launch from Cape Canaveral Air Force Station on March 13 to deliver the Air Force's tenth Wideband Global SATCOM (WGS-10) military communications satellite into orbit.
The common booster core first stage and the Delta Cryogenic Second Stage arrived in July, 2018 at Cape Canaveral Air Force Station from our factory in Decatur, Alabama, sailing to Florida aboard the Mariner cargo vessel. Technicians then mated the two stages together in the Horizontal Integration Facility (HIF) and completed rigorous testing.
The 170-foot-long rocket was moved from the HIF to Space Launch Complex-37 on Thursday, Jan. 24, riding a 36-wheel, diesel-powered transporter down the road and up the ramp to the launch pad.

After reaching the pad, cradle-like pallets holding the rocket were secured to the Fixed Pad Erector on the pad's surface. Two hydraulic pistons rotated the orange and white rocket vertically onto the pad's launch table on Friday, Jan. 25, achieving the Launch Vehicle on Stand, or LVOS, pre-launch milestone.
Coming up next in the launch campaign, the four solid rocket boosters (SRBs) will be attached to the first stage.
This will mark ULA's 133rd mission, our 51st for the Air Force, the 39th Delta IV rocket to launch and the 8th in the Medium+ (5,4) configuration with a five-meter-diameter upper stage and four SRBs.

Each of the Graphite Epoxy Motors measures 60 inches in diameter and is 53 feet in length. They were delivered to Space Launch Complex-37 and sequentially attached over the last week.
Known as GEM-60s, all four boosters will be ignited at the launch pad and deliver a combined 1.1 million pounds of thrust to augment the more than 705,000 pounds of thrust produced by the RS-68A main engine to power the Delta IV rocket skyward.
The boosters are manufactured by Northrop Grumman, and 62 have flown to date on Delta IV rockets.

The SRM mating completes the initial buildup of the launch vehicle. The two cryogenic stages were integrated at the nearby Horizontal Integration Facility (HIF) and rolled out to the launch pad on Jan. 24.
The encapsulated WGS-10 payload will be hoisted atop the Delta IV later in the launch campaign to complete the 218-foot-tall rocket.
Liftoff remains on track for March 13.
ЦитироватьDELTA IV ROCKET RECEIVES ITS MILITARY PAYLOAD
Feb. 27, 2019 -- The U.S. Air Force's tenth Wideband Global SATCOM (WGS) military communications satellite was hoisted aboard a United Launch Alliance Delta IV rocket on Feb. 26 in final preparation for its journey into space.
The WGS-10 spacecraft, already encapsulated in the 47-foot-long composite payload fairing, was moved from its processing facility to the seaside launch pad at Cape Canaveral Air Force Station's Space Launch Complex-37 at a top speed never exceeding 5 mph. The payload was hauled by a motorized KAMAG Elevating Platform Transporter (EPT) that provided hydraulic leveling and precision positioning capabilities along the route. The EPT also towed a Portable Environmental Control System (PECS) trailer to supply conditioned air to the fairing during the trip.
Once parked in the hoistway on the backside of the Mobile Service Tower (MST), technicians used the crane system in the gantry to carefully lift the encapsulated satellite atop the Delta IV rocket's second stage to complete a successful vertical integration of the launch vehicle and payload. The fully-assembled rocket now stands 218 feet tall.
A payload's installation on the rocket signals a major milestone in the final launch campaign after years of diligent work by the spacecraft and launch vehicle production teams, engineers and specialists to prepare a new national asset to be boosted into orbit.
A tip-to-tail electrical test of the combined payload and launch vehicle will occur later this week, an operation known as the Integrated Systems Test (IST).
Once that is completed, the comprehensive review process to verify flight readiness will begin in parallel to final vehicle closeouts for the targeted March 13 launch.
The WGS system is a constellation of the Defense Department's highest capacity communications satellites in geosynchronous orbit. The satellites provide essential connectivity to the U.S. military and allied partners, allowing combatant commanders to exert command and control of their tactical forces, from peace time to military operations.

The addition of a U.S. Air Force communications satellite has capped the assembly of a 218-foot-tall (66-meter) United Launch Alliance Delta 4 rocket at Cape Canaveral set for liftoff the evening of March 13.
The Air Force's 10th Wideband Global SATCOM communications satellite joined the Delta 4 rocket at Cape Canaveral's Complex 37 launch pad early Tuesday after an overnight trip from the Astrotech spacecraft processing facility in nearby Titusville.
After arriving from its factory in Southern California late last year, the Boeing-built communications satellite was fueled with maneuvering propellants at the Astrotech facility, then encapsulated inside the Delta 4 rocket's payload shroud, emblazoned with the mission's official insignia.
Cocooned inside the protective 47-foot-tall (14-meter) payload fairing on a special transporter, the WGS 10 satellite left the Astrotech facility late Monday under a security escort for the low-speed journey to the launch pad.
The convoy included equipment to supply conditioned air to the satellite during the trip to the pad.
Cranes at Complex 37 raised the spacecraft and payload fairing inside the pad's mobile gantry, then workers carefully lowered the satellite on the rocket's second stage. Teams planned to spend the next couple of weeks verifying the mechanical and electrical connections between the Delta 4 launcher and the WGS 10 spacecraft, convening readiness reviews, and practicing countdown procedures.
Liftoff of the Delta 4 rocket is scheduled for March 13, during a launch window opening at 6:58 p.m. EDT (2258 GMT). The launch window extends until 9:04 p.m. EDT (0104 GMT).

Boosted by an Aerojet Rocketdyne hydrogen-fueled RS-68A main engine and four strap-on solid rocket motors built by Northrop Grumman Innovation Systems, the Delta 4 rocket will head east from Cape Canaveral to place the WGS 10 spacecraft into an elliptical geostationary transfer orbit, a waypoint on the satellite's journey to an operating post more than 22,000 miles (nearly 36,000 kilometers) over the equator.
WGS 10 will join a military satellite fleet to route classified and unclassified data and video, supporting U.S and allied forces around the world. Featuring a digital channelizer, WGS 10 will relay high-data-rate communications in X-band and Ka-band frequencies during a mission expected to last at least 14 years.
The nine previous WGS satellites all launched on ULA rockets — the first two on Atlas 5s in 2007 and 2009, and the following seven on Delta 4s.
The Wideband Global SATCOM fleet is the U.S. Defense Department's highest capacity satellite communications network.
The launch March 13 will be ULA's second mission of the year, the second Delta 4 flight of the year, and the third launch from Florida's Space Coast overall so far in 2019.
The mission will be the 39th flight by a Delta 4 rocket since the launcher family debuted in 2002, and the eighth launch by a Delta 4 flying in the "5,4" configuration with a 5-meter (16-foot) diameter payload fairing and four solid rocket boosters.
The Delta 4's first and second stages, covered in insulating orange foam, rolled out of ULA's Horizontal Integration Facility to the launch pad Jan. 24, then hoisted vertical. The four solid rocket boosters, measuring 60 inches (1.5 meters) in diameter and 53 feet (16 meters) long, were added around the base of the Delta 4 launcher in early February.

The upcoming flight will be the penultimate launch by a Delta 4 rocket with a single first stage core, a medium-lift variant ULA plans to retire later this year as part of the company's strategy to streamline its operations and cut costs.
The Delta 4 is more expensive than ULA's Atlas 5 rocket family, so the company decided in 2014 to phase out most of the Delta 4 configurations.
ULA, a 50-50 joint venture between Boeing and Lockheed Martin, will continue flying the Delta 4-Heavy through the early 2020s. The Delta 4-Heavy is composed of three liquid-fueled first stage cores connected together to haul heftier payloads into space.
Meanwhile, ULA is developing a new rocket named the Vulcan set for an inaugural flight in 2021. The Vulcan launcher will eventually fully replace the entire Atlas and a Delta rocket families.
The final single-core Delta 4 rocket is scheduled for launch from Cape Canaveral in July with a GPS navigation satellite.

United Launch Alliance ground crews are putting the final touches on a Delta 4 rocket scheduled for blastoff Friday evening from Cape Canaveral with a U.S. Air Force communications satellite.
The 218-foot-tall (66-meter) Delta 4 rocket is set for liftoff at 6:56 p.m. EDT (2256 GMT) Friday, around a half-hour before sunset on Florida's Space Coast. Friday night's launch window extends until 9:05 p.m. EDT (0105 GMT).
The payload for the Delta 4 rocket is the Air Force's Boeing-built WGS 10 communications satellite, which will join a fleet of wideband relay nodes stationed around the world in geostationary orbit more than 22,000 miles (nearly 36,000 kilometers) over the equator.
Friday evening's mission will be the third launch of the year from Cape Canaveral, and ULA's second mission of 2019, following a Delta 4-Heavy flight Jan. 19 from Vandenberg Air Force Base in California.
The Delta 4 launcher, covered in orange thermal insulation over its cryogenic propellant tanks, will blast off with 1.8 million pounds of thrust and head due east from Cape Canaveral, releasing four Northrop Grumman-built strap-on solid rocket motors around a minute-and-a-half into the flight to fall into the Atlantic Ocean. The four solid rocket boosters should leave a twisting exhaust plume in their wake as the Delta 4 climbs into space, adding to the spectacle for beachgoers and space enthusiasts hoping to see the launch.
The Delta 4 will jettison the protective aerodynamic shroud over the WGS 10 spacecraft nearly two minutes later, and the rocket's core stage hydrogen-fueled RS-68A main engine, made by Aerojet Rocketdyne, will shut down at T+plus 3 minutes, 55 seconds.
Seconds later, the Delta 4's lower stage will drop away, and the upper stage's RL10B-2 engine will ignite for around 15 minutes to place the WGS 10 spacecraft in a preliminary parking orbit. A restart of the RL10B-2 engine at T+plus 29 minutes, 29 seconds, will raise the high point of the rocket's orbit to an altitude of 27,536 miles (44,315 kilometers), setting up for deployment of the more than 13,000-pound (nearly 6,000-kilogram) WGS 10 satellite at T+plus 36 minutes, 50 seconds.
Like its predecessors already in orbit, the Air Force's 10th Wideband Global SATCOM communications satellite will route classified and unclassified data and video, supporting U.S and allied forces around the world. Featuring a digital channelizer, WGS 10 will relay high-data-rate communications in X-band and Ka-band frequencies during a mission expected to last at least 14 years.The weather outlook for Friday night's launch looks favorable, with a 70 percent probability of acceptable conditions. The only potential weather concern forecast by the Air Force's 45th Weather Squadron is the possibility of violating the cumulus cloud rule during the countdown.Спойлер

The nine previous WGS satellites all launched on ULA rockets — the first two on Atlas 5s in 2007 and 2009, and the following seven on Delta 4s.
"ULA is proud to be the exclusive launch provider for all ten WGS missions," said Gary Wentz, ULA vice president of government and commercial Programs. "Our focus on mission success continually demonstrates that safely and reliably delivering these critical national assets is our highest priority."[свернуть]
"During the launch window, there is a slight possibility of an isolated shower early in the window as any showers that form inland could move back over the coast with southwesterly steering flow before diminishing shortly after sunset," the Air Force's forecast team wrote Wednesday.
At launch time, forecasters predict scattered clouds at 3,000 feet, broken clouds at 28,000 feet, and winds of 15 knots from the south-southeast. The temperature at launch time is forecast to be around 72 to 75 degrees Fahrenheit.
If the launch is delayed to Saturday, weather conditions are expected to worsen as a cold front moves into Central Florida. There is a 60 percent probability of weather conditions violating one of the Delta 4's launch weather rules Saturday.
The Delta 4's launch with the WGS 10 communications satellite was previously scheduled for Wednesday, March 13. ULA announced a two-day delay Saturday "to allow for additional troubleshooting to resolve some off-nominal data indications."
ULA and Air Force officials are scheduled to meet Thursday morning for a launch readiness review to clear the Delta 4 rocket for final countdown preparations.

Tenth WGS satellite to serve U.S. warfighters
March 13, 2019 -- United Launch Alliance will deliver the tenth communications satellite into space for the U.S. military's Wideband Global SATCOM constellation with the launch of WGS-10 aboard a Delta IV rocket on Friday.
(https://24liveblog.tradingfront.cn/event/2208918329522966869/20190313195855_752127.jpg) (https://photo.24liveblog.com/2208918329522966869/20190313195855_752127.jpg)
The launch is scheduled for 6:56 p.m. EDT (2256 UTC) from Space Launch Complex-37 at Cape Canaveral Air Force Station, Florida. The evening's launch window extends to 9:05 p.m. EDT (0105 UTC), a duration of 129 minutes.
The WGS satellites operate in geostationary orbit 22,300 miles above Earth and serve as the backbone for communications "anytime, anywhere" around the world for troops, aircraft, ships.
"ULA is proud to be the exclusive launch provider for all ten WGS missions," said Gary Wentz, ULA vice president of Government and Commercial Programs. "Our focus on mission success continually demonstrates that safely and reliably delivering these critical national assets is our highest priority."
Joining the U.S. in the WGS system are the partner nations of Australia, Canada, the Czech Republic, Denmark, Luxembourg, the Netherlands, Norway and New Zealand. They have financed aspects of the program in exchange for global communications services.
Boeing built the 10 spacecraft in the program at its factory in El Segundo, California. The craft use the Boeing 702HP bus with conventional and xenon-ion propulsion systems, highly efficient triple-junction gallium arsenide solar cells and deployable radiators with flexible heat pipes.

The solar arrays on each satellite stretch 135 feet tip-to-tip, a wingspan larger than a Boeing 737 but smaller than a Boeing 747. Each craft weighs about 13,000 pounds at launch.
The WGS satellites place shaped, steerable spot beams of bandwidth for Ka- and X-band frequencies, plus the onboard capability to switch signals from one band to the other. Each satellite has electrically-steerable, phased array antennas for X-band transmitting and receiving, mechanically-steered Ka-band antennas and a fixed full-Earth-coverage beam also in X-band. The antennas provide 19 independent coverage areas — 10 Ka-band and 8 X-band spot beams, plus the full-Earth footprint.
The Delta IV Medium+ (5,4) rocket will be powered into the evening sky by its RS-68A main engine and four side-mounted solid rocket motors, heading eastward above the Atlantic Ocean.

The solids will burn out and jettison about 100 seconds into flight, followed by payload fairing separation two minutes later and staging of the common booster core first stage from the Delta Cryogenic Second Stage (DCSS) four minutes after liftoff.
The second stage will perform two firings of its RL10B-2 engine, one for 15 minutes to reach a parking orbit and a second time for three-and-a-half minutes to achieve the targeted super-synchronous transfer orbit to deploy WGS-10. Spacecraft separation is expected 37 minutes after launch.
This will mark ULA's 133rd flight, the 383rd Delta launch in history and our second Delta IV launch this year.
The launch weather forecast calls for some scattered clouds, good visibility, a chance of showers inland, southeasterly winds of 15 knots and a temperature in the low 70s F. There is a 70 percent chance of favorable liftoff weather conditions, with cumulus clouds the primary concern.

Launch Readiness Review completed
The Mission Management Team has given a "go" for liftoff of the United Launch Alliance Delta IV rocket carrying the Wideband Global SATCOM (WGS)-10 communications spacecraft for the Air Force on Friday.
The Launch Readiness Review, chaired by Tom Heter III, ULA's launch director for WGS-10, was completed this morning at the Delta Operations Center. Leaders from ULA and the Air Force assessed all aspects pf mission readiness, discussed the status of pre-flight processing work, heard technical overviews of the countdown and flight, and previewed the weather forecast.
At the conclusion of the meeting, the managers were polled, gave a unanimous "go" for launch and then signed the Launch Readiness Certificate.
Friday's launch is scheduled for 6:56 p.m. EDT (2256 UTC) from Space Launch Complex-37 at Cape Canaveral Air Force Station, Florida.
The official launch weather forecast, according to the 45th Weather Squadron, now calls for an 80 percent chance of favorable conditions for the liftoff, with scattered low clouds and broken high-level clouds, south-southeasterly winds at 12 peaking to 16 knots and a temperature in the mid 70s F. The only concern for a launch weather rule violation will be cumulus clouds.

It's launch day at Cape Canaveral, where a Delta 4 rocket is set for liftoff at 6:56 p.m. EDT (2256 GMT) carrying the U.S. Air Force's tenth Wideband Global SATCOM communications satellite into orbit.
One of the first steps this morning in preparation for launch will be the retraction of the Delta 4's mobile gantry at the Complex 37B launch pad. The 330-foot-tall structure will roll away from the Delta 4 to its launch position just northeast of the pad.
The tower protected the rocket from weather during launch preparations, and helped workers access the launcher since it arrived at the pad in late January. The tower weighs about 9 million pounds, and is one of the tallest launch pad structures at Cape Canaveral.
The first few hours of today's countdown will include the power-up of the Delta 4 rocket, checkout of its guidance and control systems, and final securing of the vehicle and the launch pad before workers evacuate the area in advance of fueling.
Two built-in holds are planned in today's countdown at T-minus 4 hours, 15 minutes, and at T-minus 4 minutes.
Filling of the Delta 4 rocket with super-cold liquid hydrogen and liquid oxygen, which powers both stages of the launcher, should begin soon after 2 p.m. EDT (1800 GMT).
We are pleased to provide full coverage of today's launch after United Launch Alliance reversed its earlier decision not to provide the news media with countdown audio for its launches.

Countdown begins!
We are heading into space tonight, and the countdown has been initiated! We are just eight-and-a-half hours away from liftoff of the Delta IV Medium+ (5,4) rocket to add the tenth satellite to the U.S. military's Wideband Global SATCOM constellation, the backbone of worldwide communications connectivity for American and allied military forces.
The application of power to the avionics aboard the Delta IV rocket is beginning at the start of the countdown. The equipment will be powered up for launch day testing and final preparations for fueling operations.
At Space Launch Complex-37, the Mobile Service Tower retraction to the launch position is scheduled to begin shortly. A check of the weather conditions will be made by mission managers five minutes from now.

Weather acceptable for tower roll
The 45th Weather Squadron here at Cape Canaveral Air Force Station has provided a forecast of conditions expected during retraction of the Mobile Service Tower away from the Delta IV rocket and the outlook for the rest of the day.
Current conditions are favorable to proceed with tower roll, with winds within limits and no adverse weather in the area. Also, the weather for the afternoon hours when the vehicle will be exposed during fueling operations also poses no concern for lightning or high winds.
For launch this evening at 6:56 p.m. EDT, meteorologists are predicting scattered and high broken clouds, good visibility, south-southeasterly winds of 12 knots, gusting to 16 knots and a temperature in the mid 70s F.
Overall, there is an 80 percent chance of favorable launch weather.
The primary concern will be any showers forming inland and migrating back towards the coast to violate the cumulus cloud rule. Even if that happens, meteorologists say the no-go condition should not linger too long.

These photos show the 330-foot-tall mobile service tower moving into position for liftoff of a Delta 4 rocket from Cape Canaveral's Complex 37B launch pad Friday.
The 218-foot-tall (66-meter) rocket is set for liftoff during a launch window opening at 6:56 p.m. EDT (2256 GMT) and extending to 9:05 p.m. EDT (0105 GMT). The mission's payload is the U.S. Air Force's tenth Wideband Global SATCOM spacecraft, valued at roughly $400 million, to extend the reach of the military's highest-capacity satellite communications network.
The Delta 4 rocket will be powered off the launch pad with an Aerojet Rocketdyne RS-68A main engine and four solid rocket boosters built by Northrop Grumman Innovation Systems. The hydrogen-fueled core stage and solid-fueled strap-on motors will combine to generate 1.8 million pounds of thrust at liftoff.Спойлер

WGS 10 separation confirmed! The Boeing-built WGS 10 communications satellite has separated fr om the Delta 4 rocket's second stage.
WGS 10 will use its on-board propulsion system, using a liquid-fueled main engine and plasma thrusters, to maneuver into a circular geostationary orbit around four months after launch, wh ere it will begin final checkouts and enter service for the U.S. Air Force. The Delta 4's RL10B-2 engine will reignite at T+plus 1 hour, 12 minutes, for a 10-second firing to aim for a destructive re-entry over the Pacific Ocean around 12 hours after liftoff.

After the completion of the primary mission tonight, the second stage will perform a third and final burn. Engine start is expected in about 35 minutes. This brief, 10-second firing will serve as a de-orbit burn by lowering the rocket body's perigee for disposal into the atmosphere at the end of this revolution of the globe, which will occur about 11 hours from now. The disposal guards against unnecessary space debris.

The traditional quick-look post-flight data review of today's mission has occurred at the Delta Operations Center following the successful launch by the United Launch Alliance Delta IV rocket.
Today's launch represents the 133rd successful mission for United Launch Alliance and our 51st for the Air Force. This flight also marked the 39th mission for the Delta IV. We've now successfully launched all 10 satellites for the WGS constellation.
Liftoff occurred at 8:26:00.122 p.m. EDT.
Engineers representing various launch vehicle elements offered brief synopses of system performance -- such as the engines, hydraulics and avionics. The vehicle performed nominally during its mission and injected the WGS-10 payload into a good orbit.
The quick-look meeting received congratulatory speeches from company leadership and the customer. ULA officials expressed appreciation to the Air Force in being entrusted in launching this national asset.
Today's mission occurred on the anniversaries of three previous launches of ULA heritage vehicles -- two Atlas missions and a Delta II that launched a GPS IIR navigation satellite.

Cape Canaveral Air Force Station, Fla., (March 15, 2019) – A United Launch Alliance (ULA) Delta IV rocket carrying the tenth Wideband Global SATCOM (WGS) satellite for the U.S. Air Force lifted off from Space Launch Complex-37 on March 15 at 8:26 p.m. EDT. ULA has been the exclusive launch provider for all ten WGS satellites.
"We are very proud to deliver this critical asset to orbit in support of the U.S. and Allied warfighters deployed around the world defending our national security," said Gary Wentz, ULA vice president of Government and Commercial Programs. "Thank you to the entire ULA team and mission partners for their outstanding teamwork and dedication to mission success."
The WGS-10 satellite, built by the Boeing Company, is an important element of the new high-capacity satellite communications system. Each WGS satellite provides more wideband communications capacity than the entire Defense Satellite Communications System.
This mission launched aboard a Delta IV Medium+ (5,4) configuration vehicle, built in Decatur, Alabama, including a 5-meter Payload Fairing and standing at 218 feet. The common booster core for Delta IV was powered by the RS-68A engine, and the Delta Cryogenic Second Stage was powered by the RL10B-2 engine, both supplied by Aerojet Rocketdyne. Northrop Grumman provided the four solid rocket motors. At liftoff, the main engine and four solid rocket motors comined to produce approximately 1.7 million pounds of thrust.
To date ULA has a track record of 100 percent mission success with 133 successful launches.
With more than a century of combined heritage, ULA is the world's most experienced and reliable launch service provider. ULA has successfully delivered more than 130 satellites to orbit that provide Earth observation capabilities, enable global communications, unlock the mysteries of our solar system, and support life-saving technology.

Вашингтон. 16 марта. ИНТЕРФАКС - Ракета-носитель Delta IV в субботу успешно вывела на орбиту 10-й спутник глобальной системы широкополосной связи Wideband Global Satcom (WGS-10) в интересах ВВС США, сообщила компания United Launch Alliance.
Старт ракеты-носителя Delta IV со спутником был осуществлен компанией с 37-го космического пускового комплекса на авиабазе ВВС США на мысе Канаверал (штат Флорида) в 03:26 мск.Спойлер
United Launch Alliance - совместное предприятие корпораций Boeing и Lockheed Martin, которое осуществляет запуски в интересах Пентагона и американского разведывательного сообщества.
Wideband Global Satcom является военной спутниковой системой связи нового поколения для защищенной и скоростной передачи данных, которая стала основой коммуникаций американских военных.
Спутник WGS-10, а также его предшественники WGS-9 и WGS-8 относятся к серии Block 2 Follow-On, главной особенностью которых является использование усовершенствованных цифровых каналообразующих устройств, которые почти вдвое превосходят доступную полосу пропускания более ранних спутников WGS.
Цифровой формирователь каналов дает возможность пользователю с терминалом любого из двух Ка или Х диапазонов беспрепятственно связываться с любым другим таким терминалом, обеспечивая необходимые преобразования частоты на борту. В зависимости от используемого терминала скорость передачи данных спутника WGS может составлять от 2,4 Гбит/с до 3,6 Гбит/с. Пропускная способность составляет до 1,9 тыс. субканалов. Антенный комплекс аппарата может формировать 19 независимых зон покрытия. К спутнику можно подключаться с любой точки мира.
Космические аппараты WGS серии Block II, в частности, призваны существенно улучшить передачу информации с беспилотных летательных аппаратов, которые используются для наблюдения, сбора разведданных и нанесения ракетно-бомбовых ударов.
В целом, модернизированные спутники помогут в удовлетворении растущего спроса вооруженных сил США на высокоскоростную передачу данных.
Управление группировкой орбитальной группировкой космических аппаратов WGS осуществляют ВВС США.
Всего планируется вывести на орбиту 12 спутников WGS. Стоимость их усовершенствованной версии оценивается в $425 млн. Срок активного функционирования каждого аппарата составляет 14 лет.
Все спутники WGS выводятся на геостационарную орбиту высотой около 35750 км с наклонением орбиты в 0 градусов. Их масса составляет 5987 кг.[свернуть]

United Launch Alliance placed a new satellite in orbit with a fiery Friday night blastoff fr om Cape Canaveral, using a version of the Delta 4 rocket that is nearing retirement to supplement a U.S. military network relaying signals fr om drones and battlefield commanders.
After ground teams cleared several technical hurdles with the rocket and a satellite tracking network, the 218-foot-tall (66-meter) Delta 4 launcher's hydrogen-fueled RS-68A main engine flashed to life with an orange burst of flame moments before liftoff.
Five seconds later, four solid rocket motors ignited, and hold-down bolts released at 8:26 p.m. EDT Friday (0026 GMT Saturday) as the Delta 4 rapidly climbed away fr om Cape Canaveral's Complex 37B launch pad with 1.8 million pounds of thrust.
The main engine and booster nozzles vectored their thrust to guide the Delta 4 east over the Atlantic Ocean, sending the U.S. Air Force's tenth Wideband Global SATCOM communications satellite toward its final operating position more than 22,000 miles (nearly 36,000 kilometers) over the equator in geostationary orbit.
The Delta 4's solid rocket boosters, built by Northrop Grumman, burned out and jettisoned in two pairs around 1 minute, 40 seconds, into the mission. Once above the dense lower layers of the atmosphere, the Delta 4 released its nose cone to reveal the WGS 10 satellite.
The Aerojet Rocketdyne RS-68A main engine fired nearly four minutes until the first stage released to fall into the Atlantic Ocean. An upper stage RL10B-2 engine, also supplied by Aerojet Rocketdyne, ignited two times to loft the WGS 10 spacecraft into an elliptical transfer orbit ranging as high as 27,500 miles (44,300 kilometers) above Earth.
The Boeing-built WGS 10 satellite separated from the Delta 4's upper stage at T+plus 36 minutes, 50 seconds, extending the company's streak of successful missions to 133 since its formation in 2006.Спойлер

Friday night's launch was delayed 90 minutes to allow time for engineers to examine technical concerns on the first and second stages of the Delta 4 rocket. Once those issues were cleared, the launch team had to wait for officials to ensure NASA's Tracking and Data Relay Satellite System was ready to route telemetry from the rocket to ground controllers.
The mission marked the next-to-last flight of the Delta 4 rocket variant with a single first stage core — known as the Delta 4-Medium — as ULA begins retiring segments of its launcher family in preparation for the debut of the new Vulcan booster, which the company says will be less expensive than the existing Atlas and Delta fleet.
Gary Wentz, ULA's vice president of government and commercial programs, said the company's decision in 2014 to retire the Delta 4-Medium was intended to reduce the company's costs.
"We started looking at the products that we were providing, and found that maintaining these two families of launch vehicles, both the Delta and the Atlas, through this period decreased our flight rate, and therefore increased our costs," Wentz said. "That really drove it, based on the competitive industry we're in, trying to maximize our competitiveness."
The Delta 4-Medium family provides the same range of lift capability as the less expensive Atlas 5 rocket. The Delta 4-Heavy, which will remain operational through at least the early-to-mid-2020s, uses three Delta 4 first stage cores bolted together to haul heavier payloads to orbit than any of the Atlas 5 configurations.
ULA was formed in 2006 by the merger of Boeing's Delta 4 and Lockheed Martin's Atlas 5 rocket programs. The 50-50 joint venture kept both rocket lines operational to ensure the U.S. military had two independent launch options for national security satellites.
But SpaceX's Falcon 9 and Falcon Heavy rockets are now certified to launch U.S. national security payloads. With the Falcon and Atlas rocket families, the military will continue to have two launch options after the Delta 4-Medium's retirement.

Friday's launch used the Delta 4-Medium+ 5,4 rocket variant, with four solid rocket boosters and a 5.1-meter (16.7-foot) upper stage and payload shroud. It was the eighth and final flight of the Delta 4-Medium+ 5,4 configuration, and all carried WGS satellites for the Air Force.
One more Delta 4-Medium rocket is set for launch July 25 from Cape Canaveral with an Air Force GPS navigation satellite. That launcher will fly in the Delta 4-Medium+ 4,2 configuration, with two solid rocket boosters and a 4-meter (13.1-foot) diameter upper stage and payload fairing.
With Friday's launch, the Delta 4 rocket has flown 39 times since November 2002, and 28 of those missions used a Delta 4-Medium.
"It's had a very successful history, and it's similar to the WGS satellite, it's a workhorse for the Air Force," Wentz said of the Delta 4-Medium. "It's kind of bittersweet that we're here at the end, but we look forward to the missions to come in the future, and the vehicles that we'll field."
Including the GPS launch in July, ULA has contracts in place for six Delta 4 flights through 2024. The five Delta 4-Heavy launches planned in the early 2020s will all hoist top secret payloads for the National Reconnaissance Office, the U.S. government's spy satellite agency:[/li]

The WGS fleet transmits classified and unclassified signals, supporting U.S and allied forces around the world. Featuring a digital channelizer, the roughly $400 million WGS 10 satellite will relay high-data-rate communications in X-band and Ka-band frequencies during a mission expected to last at least 14 years.

"WGS has the unique ability to cross-band between military Ka- and X-band, which provides our warfighters significant flexibility to maximize communications capability," said Tom Becht, director of the military satellite communications directorate at the Air Force's Space and Missile Systems Center in Los Angeles.
The nine previous WGS satellites all launched on ULA rockets — the first two on Atlas 5s in 2007 and 2009, and the following seven on Delta 4s. The Wideband Global SATCOM fleet is the U.S. Defense Department's highest capacity satellite communications network.
Two of the 10 WGS satellites launched to date were funded by international governments. WGS 6 was funded by Australia, and a consortium including Canada, Denmark, Luxembourg, the Netherlands and New Zealand paid for the WGS 9 satellite launched in March 2017. In exchange for their contributions, those nations' militaries gain access to the WGS network.
WGS 10 is the fourth and final "Block II Follow-On" WGS satellite, and it's the third with the digital channelizer, which handles communications signals more efficiently, nearly doubling the bandwidth provided by earlier spacecraft in the series.
Based on the Boeing 702 satellite platform, WGS 10 will use a liquid-fueled boost engine and plasma thrusters to circularize its orbit more than 22,000 miles over the equator. The maneuvers will take about four months, officials said, before WGS 10 reaches geostationary orbit, wh ere its velocity will match the rate of Earth's rotation.
After a two-month test campaign in geostationary orbit over the United States, military leaders will decide wh ere to deploy WGS 10.
Army Col. Enrique Costas, project manager for defense communications and Army transmission systems, said the WGS network is widely-used in the military because of its reliability and high-bandwidth capacity, enabling live video transmissions from drones around the world back to operators hundreds or thousands of miles away.
"If I was to target a specific terrorist in the Middle East, and I have an ISR (Intelligence, Surveillance and Reconnaissance) platform that is looking at that terrorist, I need to be able to make a decision whether or not to fire, or send a ground team to get that target," Costas said.
High-resolution video streaming from a flying drone requires a lot of bandwidth, he said.
"I need to be able to transmit that signal from the point of collection all the way back to the center wh ere the decision is going to be made whether to not to pull the trigger or deploy a team to act upon a specific mission," Costas told reporters in a pre-launch conference call. "WGS is one of the primary ISR carriers for operational workforce in some theaters."
The White House and State Department also rely on WGS satellites, and the network broadcasts TV signals to troops stationed around the world.
"If ... I have a telecon between the (combatant commander) and the president of the United States, I want to make sure that the signal doesn't go down at any time during that conversation to make critical decisions," Costas continued. "WGS is part of that transport to make sure that we have reliable and assured communications regardless of wh ere we are on the planet."
The Air Force is close to awarding a new contract to Boeing for at least one additional WGS satellite.
Congress added $600 million to the fiscal year 2018 defense budget for two new WGS satellites, overruling the military's plans to begin sourcing more communications capacity from commercial satellites. But the funding line included no money to launch the satellites, each of which costs between $300 million and $400 million.
The Air Force has kicked off another round of WGS procurement using the unexpected money, and Boeing submitted a proposal in January. Military officials have not decided whether to order one or two more WGS satellites, according to Becht. He said a final decision and contract signature is expected later this year.
Becht said the Air Force could follow a purchasing model often used by commercial satellite operators, in which Boeing would be responsible for building the new WGS spacecraft using more cost-effective practices. Boeing could also select a launch provider for the new WGS spacecraft, bundling the entire mission into one turnkey contract, with final delivery of the satellite to the Air Force after it is in orbit.
"The capabilities of the WGS system are supporting our allies around the world in joint missions, and helping our military to be more effective," said Rico Attanasio, Boeing's director of tactical communications. "Moving forward, as the need for resilience in SATCOM grows, I'm confident WGS will continue to be a key element in meeting the needs of assured protected communications."[свернуть]

LOS ANGELES AIR FORCE BASE, Calif. --
The Air Force successfully launched the 10th Boeing-built Wideband Global SATCOM satellite aboard a United Launch Alliance Delta IV Evolved Expendable Launch Vehicle for the U.S. from Space Launch Complex 37B, Cape Canaveral Air Force Station, Florida at 8:26 p.m. EDT, March 15.
This mission demonstrates the U.S. Air Force's continued commitment to deliver secure and reliable satellite communications around the globe to U.S. and Allied forces.
"Today's launch is a momentous achievement for the joint warfighter as we launch the tenth WGS satellite," said Tom Becht, acting director of Space and Missile Systems Center's Military Satellite Communications Systems Directorate. "This accomplishment is the result of the remarkable relationship with our partners at SMC's Launch Enterprise Systems Directorate, the 45th Space Wing, 50th Space Wing, and industry and epitomizes the traits of our transformative SMC 2.0 initiative."
"The tenacity and dedication to mission assurance ensures we continue to maintain a robust satellite constellation with modernized, more resilient MILSATCOM capabilities," Becht continued. "Thanks to the astounding teamwork, commitment, and mission focus, we successfully launched the next satellite in the WGS satellite constellation."
Over the next few months, Boeing will begin on-orbit testing of WGS-10 to verify performance and prepare the satellite for operational use. Ultimately, WGS-10 will be controlled by the U.S. Air Force's 4th Space Operations Squadron at Schriever Air Force Base, Colo. The WGS-10 satellite is scheduled to enter operations in October 2019.

SCHRIEVER AIR FORCE BASE, Colo. --The 4th Space Operations Squadron accepted control of the 10th Wideband Global Satellite during a ceremony at Schriever Air Force Base, Colorado, July 10, 2019.
The platform was launched earlier this year aboard a United Launch Alliance Delta IV Evolved Expendable Launch Vehicle from Space Launch Complex 37B, Cape Canaveral Air Force Station, Florida, March 15.
In the ceremony, the satellite was transferred from the Space and Missile Systems Center to the 14th Air Force, who then transferred the responsibility of the vehicle down through the 50th Space Wing, 50th Operations Group and finally to 4th SOPS.
First Lt. Dion Tchokreff, 4th SOPS WGS engineer, said the transfer marks the official ownership and control of the satellite by an Air Force entity and will enhance the capabilities of the WGS series.
"WGS-10 will increase the strength in signal of the existing nine-vehicle constellation by 17 percent," he said.Following launch, Boeing conducted a series of on-orbit to verify the performance of the satellite for this moment.
"The Boeing and 4th SOPS launch, and early orbit team, went through a two-month rehearsal and a four-month execution period to ensure the vehicle safely arrived to geostationary orbit," Tchokreff said.
WGS-10 is the second WGS satellite accepted since the now deactivated 3rd Space Operations Squadron unified with the 4th SOPS.
"It's been two years since the merger and the teams have come together as demonstrated by the acceptance of this vehicle along with the previous one," said Lt. Col. Timothy Ryan, 4th SOPS commander "We are one team, with one mission and goal in sight."
WGS produces flexible, high-capacity communications for the joint warfighter by procurement and operation of the satellite constellation and the associated control systems.
"Anytime we put a satellite vehicle in orbit, we are gaining more resiliency, which is important in an operationally contested and degraded environment," Ryan said. "More importantly, it gives more of the abilities and the capabilities of the satellite to the warfighter."
The launch and transfer of authority of this platform highlights the 4th SOPS's commitment to evolving space, innovation and mastering space and alignment with the U.S. Air Force's dedication to deliver secure and reliable satellite communications around the world to support the joint warfighter.[свернуть]
