ЦитироватьOrbital ATK is targeting a price below $100 million per launch. But this is certainly the list price for the simplest version. Military launches bring extra security and mission assurance requirements that drive up cost.

Thompson: expecting joint go/no-go decision with the Air Force late this year or early next year on next phase of Next Generation Launcher.

Orbital ATK Successfully Tests First Motor Case for Next Generation Launch Vehicle

NGL System Achieves Critical Milestone with Completion of Structural Acceptance Test
Dulles, Virginia 7 November 2017 – Orbital ATK (NYSE: OA), a global leader in aerospace and defense technologies, announced it has successfully completed an important milestone in developing advanced solid rocket propulsion and other technologies to be used in a new generation of intermediate- and large-class space launch vehicles. The company is in early production of development hardware for its Next Generation Launch (NGL) system, and on October 27 successfully completed the structural acceptance test on the first motor high-strength composite case for this program.

The applied structural loads during the test demonstrated over 110 percent of maximum expected motor operating pressure and 110 percent of operational/flight and pre-launch compressive/tensile line loads. This full-scale motor case segment will be cast with inert solid rocket propellant in early 2018 and shipped to the launch site for check-out of ground operations.

"NGL is one of Orbital ATK's top growth initiatives," said Scott Lehr, President of Orbital ATK's Flight Systems Group. "This milestone clearly shows the progress being made by the hundreds of engineers and technicians in Utah and Arizona who are developing the NGL system."

Orbital ATK's NGL rocket family will be capable of launching the entire spectrum of national security payloads, as well as science and commercial satellites that are too large to be launched by the company's current Pegasus®, Minotaur and AntaresTM space launch vehicles. The NGL vehicles will share common propulsion, structures and avionics systems with other company programs, including smaller space launch vehicles as well as missile defense interceptors, target vehicles and strategic missile systems.

"By sharing a skilled workforce, facilities and subsystems across multiple programs, we've designed NGL to be affordable and reliable," said Lehr. "For example, NGL uses common avionics that have flown on more than 100 missions with 100 percent success."

The next phase of the program is expected to begin when the Air Force awards the Launch Services Agreement in mid-2018, which would entail full vehicle and launch site development, with work taking place at company facilities in Promontory and Magna, Utah; Iuka, Mississippi; Chandler, Arizona; Kennedy Space Center, Florida; and Vandenberg Air Force Base, California.

А что ж так? Деньги МО им дало, а результат ноль?

Orbital были выделены средства МО для доработки двигателя ВО ВЕ-3 для верхней ступени NGLV. 
Что-то видно не срослось. Скорее этот странный двигатель не удалось довести до приемлемых ТХ несмотря на приемлемую цену.

https://techcrunch.com/2016/01/14/orbital-atk-spacex-new-engine-contract/

ЦитироватьOrbital ATK's contract will fund the development of several propulsion system technologies, such as the Graphite Epoxy Motor (GEM) 63XL strap-on booster, the Common Booster Segment main stage, and an extendable nozzle for Kent, WA-based Blue Origin's BE-3U/EN engine.


The GEM 63XL booster is a solid-fueled motor intended to replace the Aerojet Rocketdyne AJ-60 booster, currently used on the Atlas V, and is intended to be used on the under-development ULA Vulcan launch system. Details on the Common Booster Segment aren't known yet.
The development of an extendable nozzle for the BE-3U/EN engine, which burns liquid hydrogen and liquid oxygen, represents a novel direction for Orbital ATK. Extendable nozzles, if able to change the rocket nozzle in flight, can improve efficiency of the engine over a larger envelope of altitude. Traditionally, de Laval nozzles (traditional bell nozzles) are optimized for a specific altitude and atmospheric pressure and operate sub-optimally for a large part of their flight. Altitude-compensating nozzles are an integral part of many new space launch vehicle concepts, and represented a large part of the development effort behind Lockheed Martin's failed X-33 demonstrator.

Не факт что они реально получили эти деньги. Или например BO не захотели делать вакуумную версию двигателя. У них сейчас с BE-4 работы выше крыши (и вакуумный BE-4U кстати тоже нужен). Или оказалось, что BE-3U сильно проигрывает альтернативным вариантам. Причин может быть много.

Похоже речь идет о раздвижном насадке, который не получился у Orbital ATK, или каком то способе регулировать степень расширения сопла.

Там был спор,  если что не путаю, МО деньги выделялись из бюджета замены РД-180. В результате деньги были выделены - в этом же пакете шло финансирование бэбиРаптора.
Интересно что же произошло?
ВО ВЕ-3U планировало использовать на третьей ступени NG. Может им не к спеху???

Напоминаю, что он планировался на Vulcan.

Как один из вариантов. И там тоже судя по всему будет RL-10.

Как один из возможных вариантов для удешевления.

Be-3 какой-то совершенно странный двигатель для верхней ступени, кроме как SLS его ставить совершенно некуда. для вывода спутников на ГПО обойдутся RL-10 с 3D печатью

Orbital ATK Signs Cooperative Agreement with U.S. Air Force Space and Missile Systems Center
Research and Development Agreement Enables Certification of Orbital ATK's Next Generation Launch System

Dulles, Virginia 04 January 2018 – Orbital ATK (NYSE: OA), a global leader in aerospace and defense technologies, today announced it has signed a Cooperative Research and Development Agreement (CRADA) with the U.S. Air Force's Space and Missile Systems Center (SMC). The CRADA provides the framework and plan for data exchanges needed to certify Orbital ATK's Next Generation Launch (NGL) system to carry National Security Space missions.

"Under this CRADA, Orbital ATK is better able to support SMC in being the guardians of assured access to space," said Scott Lehr, President of Orbital ATK's Flight Systems Group. "We look forward to certifying NGL to launch National Security Space Missions."

Orbital ATK is currently in early production of development hardware for NGL. To date, the company has jointly invested with the Air Force more than $200 million to develop the NGL rocket family.

In addition to launching the entire spectrum of national security payloads, the NGL family of vehicles will be capable of launching science and commercial satellites that are too large to be launched by Orbital ATK's current Pegasus®, Minotaur and AntaresTM space launch vehicles. The NGL vehicles will share common propulsion, structures and avionics systems with other company programs, including smaller space launch vehicles as well as missile defense interceptors, target vehicles and strategic missile systems.
