Этого и стоило ожидать. Тяжелая "Дельта" тоже уйдет.

Нет, она будет жить, у Юлы нет для неё замены

Так это сейчас нет. NGLS будет мощнее Атласа и Дельты и возможно заменит тяжелую дельту даже в варианте с ТТУ.

А с двигателем RS-68 что будет? 
Для SLS, если он состоится, при той частоте пусков раз в три года запасов SSME хватит на много лет...

Закроют, как и "Дельту". При успехе FH ей замена от Юлы не понадобится.

А вообще бесславное окончание. Заказ на нее был выдан в 1989 году, первый полет в 2002-м, закрытие в 2018-м. Время активного существования всего 16 лет, примерно равного времени разработки. Единственное достоинство - полеты без аварий. Но сегодня этого уже мало, стали смотреть на ценники, да и конкуренция выросла.

Также стоит отметить, что ничего выдающегося РН "Дельта-4" не выводили, кроме экспериментального "Ориона", единственного гражданского заказчика для тяжелой "Дельты".

Программа EELV началась в 1994 г. с формирования требований к СВ. Проектирование началось осенью 1995 г.

Запросы по обзору новых средств выведения ВВС выдали еще в 1989, из которых получились "развитые носители". В 1989 году никто не знал, что делать. ВВС заказали видение и из "Дельты-4" получился пшик на водороде, самом дорогом топливе.

Одной из целью программы EELV было снижение стоимости РН. Также это был ответ на гибель "Челленджера". ВВС хотело гарантировать себе доступ в космос, в чем их НАСА подвело.

еще до Челленджера ВВС заявило о носителе

The shuttle was first launched in 1981, and was declared operational in 1982. The phase-out of the ELVs began, but in 1984 the Air Force successfully argued that it needed a "complementary" ELV as a backup to the shuttle for "assured access to space" and initiated what is now known as the Titan IV program.

Дальше разговоров дело не шло. Тогда вовсю провозглашалось окончание эры РН и то, что шаттлы их заменят. Движение пошло после гибели "Челленджера".

В связи с отказом от всех модификаций Дельты кроме тяжелой ее цена вырастет до $1 млрд.

http://spacenews.com/air-force-wary-of-swapping-ulas-monopoly-for-a-different-sort-of-dependence/

ULA, whose monopoly is being challenged by Hawthorne, California-based SpaceX, plans to phase out the intermediate, or single-stick, version of the Delta 4 as early as 2018, and rely exclusively on the less expensive Atlas 5 to carry intermediate class satellites until it, too, is replaced. Although it will continue flying the three-stick Delta 4 Heavy for as long as the Air Force wants, ULA ultimately plans to field a brand new rocket, the Next Generation Launch System (NGLS), some time after 2020.
SpaceX, meanwhile, is awaiting Air Force certification of its intermediate-lift Falcon 9 rocket to carry national security missions in the coming months and plans to debut its three-stick Falcon Heavy rocket by the end of this year. The Falcon Heavy, which would compete directly with the Delta 4 Heavy, is expected to win certification by 2018 at the earliest.
During a hearing March 17 of the House Armed Services strategic forces subcommittee, Mitch Mitchell, a vice president at Aerospace Corp. and a retired Air Force major general, laid out a scenario in which the Air Force, due to the Russian-engine ban and other factors, would be solely dependent on the Falcon 9 for intermediate-class payloads and Delta 4 Heavy for the largest payloads.
ULA Chief Executive Tory Bruno added that with Delta 4 production limited to the seldom-used but critical heavy-lift variant, each vehicle would cost roughly $1 billion, an astronomical sum even by government-launch industry standards.
"It is not acceptable. Period," said Gen. John Hyten, commander of Air Force Space Command, who testified alongside Mitchell.

СКОЛЬКО? Да проще тогда всю верхнюю ступень с обтекателем к Falcon Heavy приделать или на SLS запускать

Air Force Wary of Swapping ULA's Monopoly for a Different Sort of Dependence
by Mike Gruss — March 18, 2015

"Two American-made launch vehicle families, the ULA Delta 4 series of rockets, and the SpaceX Falcon rockets, have the capability to fulfill 100 percent of the nation's launch requirements," SpaceX President Gwynne Shotwell testified. Credit: House Armed Services Committee video capture  
 
WASHINGTON – U.S. Defense Department officials and some House members fear a law passed by Congress last year could inadvertently create separate launch monopolies for two critical classes of national security payloads — intermediate and heavy.
The result could leave the Air Force one failed launch away from being without guaranteed access to space for certain missions beginning around 2019, officials warned.
The situation stems largely from a provision in the National Defense Authorization Act of 2015 that bars future use of Russian-made rocket engines for launching national security payloads. The measure, prompted by Russia's annexation of Crimea last year, would effectively sideline United Launch Alliance's Atlas 5 rocket, a workhorse powered by the Russian-made RD-180 engine that today launches most of the Pentagon's intermediate-class satellites.
Denver-based ULA, a Boeing-Lockheed Martin joint venture, currently has a monopoly on the U.S. national security launch business with the Atlas 5 and Delta 4 rockets. The Delta 4, powered by a U.S.-made engine, includes a three-core configuration that is used to launch the Defense Department's largest satellite payloads.
ULA, whose monopoly is being challenged by Hawthorne, California-based SpaceX, plans to phase out the intermediate, or single-stick, version of the Delta 4 as early as 2018, and rely exclusively on the less expensive Atlas 5 to carry intermediate class satellites until it, too, is replaced. Although it will continue flying the three-stick Delta 4 Heavy for as long as the Air Force wants, ULA ultimately plans to field a brand new rocket, the Next Generation Launch System (NGLS), some time after 2020.
SpaceX, meanwhile, is awaiting Air Force certification of its intermediate-lift Falcon 9 rocket to carry national security missions in the coming months and plans to debut its three-stick Falcon Heavy rocket by the end of this year. The Falcon Heavy, which would compete directly with the Delta 4 Heavy, is expected to win certification by 2018 at the earliest.

ULA Chief Executive Tory Bruno added that with Delta 4 production limited to the seldom-used but critical heavy-lift variant, each vehicle would cost roughly $1 billion, an astronomical sum even by government-launch industry standards.
"It is not acceptable. Period," said Gen. John Hyten, commander of Air Force Space Command, who testified alongside Mitchell.
"This is our gravest concern," added Katrina McFarland, the assistant secretary of defense for acquisition.
One way to avoid this scenario, these officials said, would be for Congress to allow ULA to purchase additional Russian-made RD-180 engines. The current law bans the use of Russian engines that were purchased after February 2014 for national security launches.
SpaceX President Gwynne Shotwell, who testified alongside Bruno, registered SpaceX's opposition to lifting the RD-180 ban. "Not a single additional RD-180 is necessary to ensure American access to space," she testified. "Two American-made launch vehicle families, the ULA Delta 4 series of rockets, and the SpaceX Falcon rockets, have the capability to fulfill 100 percent of the nation's launch requirements."
But Rep. Mike Rogers (R-Ala.) the chairman of the subcommittee, suggested an alternative whereby Congress clarifies the language, which in its current form — at least in the Air Force's interpretation — leaves ULA with only five RD-180s available for competitions for as many as 40 launches through 2024. In that scenario, ULA would be forced to compete against SpaceX with its Delta 4, which is at least 25 percent more expensive than the Atlas 5.
Rogers said he wanted to make clear that Congress' intent was for ULA to have about 14 RD-180 engines available for the upcoming competitions. Under that provision, the Defense Department would benefit from extended competition between the Atlas 5 and Falcon 9.
Rogers said he and Rep. Jim Cooper (D-Tenn.), the subcommittee's ranking member, would work with the Pentagon to help ease the transition from the Russian engine for the Defense Department.

McCain Accuses Air Force of Stalling on RD-180 Replacement
by Mike Gruss — March 19, 2015

WASHINGTON – U.S. Sen. John McCain (R-Ariz.), the chairman of the Senate Armed Services Committee, said the Air Force has "wasted a year doing very little" to end the Defense Department's reliance on Russian rocket engines to launch national security satellites.
"Russia annexed Crimea over a year ago, yet the Air Force does not even have an acquisition strategy yet for a new rocket engine," McCain said March 18 in his opening statement for an Army and Air Force hearing. "Instead of giving this effort the level of attention needed, the Air Force has wasted a year doing very little to end our reliance on Russian rocket engines. If the Air Force is unwilling to do what's necessary to meet the 2019 deadline, they are going to have to figure out how to meet our space launch needs without the RD-180."
The RD-180 is the main engine on United Launch Alliance's Atlas 5 rocket, which along with that company's Delta 4 rocket launches virtually all U.S. national security satellites. Following Russia's annexation of Crimea from Ukraine last year, Congress mandated that the Air Force stop using the RD-180 and begin work on a U.S.-built replacement.
Congress reprogrammed $40 million for the new engine in fiscal year 2014 and allocated $220 million in 2015, directing that it be ready by 2019. Air Force officials said March 17 they could issue a draft solicitation for new engine concepts as early as April.
But McCain and other lawmakers have grown increasingly critical of the service's pace on the project.
Sens. Bill Nelson (D-Fla.) and James Inhofe (R-Okla.) took up the matter in a March 10 letter to Defense Secretary Ashton Carter. "Given the urgency of the situation and clear guidance from Congress, I am concerned at the lack of action exhibited by DOD and the Air Force," they said.
Air Force and ULA officials have argued that the schedule mandated by Congress for fielding a new American-made engine is unrealistic and are seeking a relaxation of the RD-180 ban so the company can buy more of the Russian-made engines.
Rep. Mac Thornberry (R-Texas), the chairman of the House Armed Services Committee, told reporters March 16 he wanted the Air Force to explain why an American-made rocket engine can not be ready by 2019 before he would consider easing or lifting a ban on Russian-made engines.
Nonetheless, there does seem to be some congressional support for easing the ban.

ULA Chief Executive Tory Bruno says the RD-180 ban should be delayed until an American alternative is ready. Denver-based ULA is working with Blue Origin on the BE-4, a liquid natural gas-fueled engine that Bruno has said will not be ready to fly Air Force missions before 2021.
Aerojet Rocketdne of Sacramento, California, also is working on an RD-180 alternative dubbed the AR-1 and says it can meet the 2019 deadline, but Pentagon officials remain skeptical.
McCain has been a vocal critic of the Air Force's satellite-launching program in recent years due to its high cost. In February, he accused the Air Force of "actively keeping" rocket maker SpaceX out of the national security launch market. SpaceX of Hawthorne, California, is challenging ULA's monopoly with its Falcon 9 rocket, which expected to win Air Force certification to launch national security missions by midyear.
