Cape Canaveral Air Force Station, Fla., (March 26, 2020) - A United Launch Alliance (ULA) Atlas V rocket carrying the sixth Advanced Extremely High Frequency (AEHF) communications satellite for the U.S. Space Force's Space and Missile Systems Center lifted off from Space Launch Complex-41 on March 26 at 4:18 p.m. EDT. This marks the 83rd successful launch of an Atlas V rocket, 138th launch for ULA and first mission for the U.S. Space Force.

"The success of today's launch is the culmination of years of dedication, hard work and teamwork with several of our mission partners," said Gen. Jay Raymond, Chief of Space Operations, U.S. Space Force. "From our acquisition experts at SMC, to the satellite developers at Lockheed Martin, to the aircrews at Air Mobility Command, and our range support teams at the 45th Space Wing, we greatly appreciate the collaboration with the ULA team who all contributed to this historic, first National Security Space launch under the U.S. Space Force," added Raymond. "On behalf of the U.S. Space Force and all of our joint warfighters who depend on protected SATCOM, thank you and congratulations on today's successful launch."

"Congratulations to the U.S. Space Force on liftoff of your first mission," said Tory Bruno, ULA president and CEO. "We are proud to be your partner for this historic mission and honored to have launched the entire Lockheed Martin produced AEHF constellation on Atlas V rockets. We understand the critical importance of delivering protected communications to strategic command and tactical warfighters operating on ground, sea and air."

This mission launched aboard an Atlas V 551 configuration vehicle, producing more than two and a half million pounds of thrust at liftoff. The most powerful in the Atlas V fleet, the Atlas V 551 includes a 5-meter Payload Fairing (PLF) and stands at 197 ft. tall. The Atlas booster for this mission was powered by the RD AMROSS RD-180 engine. Aerojet Rocketdyne provided the five AJ-60A solid rocket boosters (SRBs) and RL10C-1 engine for the Centaur upper stage.

With the launch of AEHF-6, the RL10 engine has flown 500 times, including hundreds of times on ULA and ULA heritage vehicles.

"Thank you to the Aerojet Rocketdyne team for your outstanding partnership," said Gary Wentz, ULA vice president of Government and Commercial Programs. "The RL10 is integral to our unique Centaur upper stage, supporting ULA's launches of military, civil and commercial satellites and has sent spacecraft to explore every planet in our solar system."

ЦитатаProtected Globally: AEHF-6 Satellite Actively Communicating With U.S. Space Force
The AEHF constellation is a critical national security asset that provides 24x7, global coverage


The sixth Lockheed Martin-built Advanced Extremely High Frequency (AEHF-6) protected communications satellite launched on March 26.

SCHRIEVER AIR FORCE BASE, COlorado, Mar. 26, 2020 - The first national security launch for the U.S. Space Force and the final satellite to build out the protected communications constellation is now connected.

The sixth Lockheed Martin (NYSE:LMT)-built Advanced Extremely High Frequency (AEHF-6) satellite launched from Cape Canaveral Air Force Station, Florida at 4:18 p.m. ET.  AEHF-6 successfully separated from its United Launch Alliance Atlas V 551 rocket approximately five hours and 45 minutes after launch and is now responding to commands from ground control.

"This is a great milestone to share with the U.S. Space Force's Space and Missiles Systems Center," said Mike Cacheiro, Vice President for Protected Communications at Lockheed Martin Space. "I am incredibly proud of the teams that made this happen over the many years supporting the program. It is a bittersweet moment and I look forward to working with the Space Force to continue deliver this system on orbit, and increase our nation's overall survivable and protected."

The AEHF-6 satellite adds increased resiliency and advanced capabilities to the AEHF-MILSTAR constellation which ensures the ability to transmit data anywhere, anytime. This marks the first launch under U.S. Space Force control.

AEHF-6 is part of the protected communications network providing global, survivable, protected communications capabilities for national leaders and tactical warfighters operating across ground, sea and air platforms.

AEHF-5, launched in 2019 and recently handed over for operations, formed the global, anti-jam system, which is an asset shared by international allies to include Canada, the Netherlands, United Kingdom and Australia.

Lockheed Martin developed and manufactured all six satellites at their production facility located in Sunnyvale, California. The satellite shipped to Cape Canaveral Air Force Station on a Super Galaxy C-5 aircraft from the 60th Air Mobility Wing at Travis Air Force Base.

Lockheed Martin is the prime contractor for the AEHF system, and the AEHF team is led by the Production Corps, Medium Earth Orbit Division, at the Space Force's Space and Missile Systems Center, at Los Angeles Air Force Base.

CAPE CANAVERAL AIR FORCE STATION, Fla. --
The U.S. Space Force Space and Missile Systems Center successfully launched the sixth Advanced Extremely High Frequency (AEHF) communications satellite at 4:18 p.m. EDT, March 26, from Space Launch Complex-41 at Cape Canaveral Air Force Station, Florida. The satellite was carried to orbit aboard a United Launch Alliance Atlas V 551 launch vehicle. This lift-off marks the 11th Atlas V 551 launch,  83rd Atlas V launch and the first for a U.S. Space Force mission.

The satellite successfully separated from the launch vehicle nearly six hours after liftoff and will now undergo approximately 120 days of orbit-raising operations, followed by approximately 30 days of on-orbit testing. After these critical events, SMC will be ready to transfer Satellite Control Authority of AEHF-6 to Space Operations Command, which is expected to occur in six to eight months after launch.

"We are thrilled to accomplish this important milestone on the last AEHF satellite. The combined integrated team worked diligently to ensure the success of this mission. The satellite is operating as expected and is ready to undergo orbit raising and on-orbit testing for the next several months after which it will provide mission critical capabilities to our warfighters," said Col. John Dukes, senior materiel leader, SMC Production Corps' Geosynchronous Orbit Division.

The SMC-procured AEHF satellite is a joint service communications system that provides connectivity across the spectrum of mission areas, including land, air and naval warfare; special operations; strategic nuclear operations; strategic defense; theater missile defense and space operations and intelligence. The AEHF system enhances the current Milstar constellation, augmenting and improving upon the capabilities of Milstar, and expanding the MILSATCOM architecture to enable enhanced capacity and flexibility. AEHF also provides secure communications for our international partners Canada, United Kingdom, Netherlands and Australia.

SMC procured AEHF-6 from Lockheed Martin Space as a part of a Firm Fixed Price Contract block buy, which included AEHF-5, for a total cost of $2.15 billion for both satellites. By buying parts for both satellites at the same time, the total costs for two satellites were reduced.

SMC plans, acquires and sustains space-based global communications supporting the President, Secretary of Defense and combat forces. The entire SMC MILSATCOM architecture consists of satellites, terminals and control stations, which provide communications for more than 16,000 air, land and sea platforms.

For your interest. We offer some unique techniques to provide "more lift" than contracted for, given performance that day. One is a depletion burn that improves specific parameters while maintaining precision on others. ie; #AEHF6 desired better Per, Incl, but exact Ap, Arg, RAAN

ЦитатаAEHF-6 Protected Communications Satellite Completes On-Orbit Testing


Lockheed Martin's sixth Advanced Extremely High Frequency (AEHF-6) protected communications satellite completed On-Orbit Testing on Aug. 27, 2020. AEHF-6 launched earlier this year on March 26.

ЦитатаSuccessful OOT demonstrates that all space vehicle performance requirements have been met and that we are on track for satellite control authority handover to Space Operations Command before the end of the year.

SUNNYVALE, Calif., Sept. 15 -- The sixth Lockheed Martin (NYSE: LMT)-built Advanced Extremely High Frequency (AEHF-6) protected communications satellite successfully completed its On-Orbit Test (OOT) period on Aug. 27, 2020.

"Successful OOT demonstrates that all space vehicle performance requirements have been met and that we are on track for satellite control authority handover to Space Operations Command before the end of the year," said Erik Daehler, director of Lockheed Martin's Protected Communications mission area. "This is a great accomplishment for the industry-government team, bringing incredible capability for our warfighters."

AEHF-6 will be part of a geostationary ring of ten satellites in the AEHF-MILSTAR constellation delivering global coverage for survivable, highly secure and protected communications (vimeo.com/398074555) for strategic command and tactical warfighters operating on ground, sea and air platforms. The satellite adds increased resiliency and advanced capabilities to this constellation, which ensures the ability to transmit data anywhere, anytime.

Besides U.S. forces, the AEHF system also serves international partners Australia, Canada, the Netherlands and the United Kingdom.

AEHF-6 was successfully launched about five months ago, on March 26, from Cape Canaveral Air Force Station, Florida, aboard a United Launch Alliance Atlas V 551 rocket.  The launch was the first mission launch for the U.S. Space Force.
As prime contractor, Lockheed Martin Space developed and manufactured all six AEHF satellites at its production facility located in Sunnyvale, California.

The AEHF team is led by the Production Corps, Geosynchronous Earth Orbit/Polar Division, at the U.S. Force's Space and Missile Systems Center, located at Los Angeles Air Force Base, California.
