Budget Shows Flightworthy Sixth-Generation Fighter Engines Ready By 2025

Steve Trimble July 31, 2020

Details of the first of two mostly secret initiatives to support the U.S. Air Force's five-year-old pursuit of a sixth-generation successor to the Lockheed Martin F-22 are now released and reveal that a critical technology for the Next-Generation Air Dominance program could become flightworthy by mid-2025.

GE Aviation and Pratt & Whitney are scheduled to complete separate competitive designs for a Next-Generation Adaptive Propulsion (NGAP) system by the second quarter of 2022 and finish assessments on a full-scale engine three years later, according to Air Force budget documents.

The schedule and spending details on the NGAP appeared for the first time in the Air Force's budget justification documents for fiscal 2021 that were submitted to Congress in February, but passed unnoticed for several months. The Air Force awarded GE and Pratt each a $427 million contract to support the NGAP program, but the details were shrouded in budget documents within the related Adaptive Engine Transition Program (AETP), an unclassified effort to develop a reengining candidate for the Lockheed F-35.

After Senate authorizers cited the Air Force's lack of transparency for justifying a $270 million budget cut for AETP this year, service officials decided to break out funding for the NGAP in budget documents.

In fact, the NGAP program reappeared in the fiscal 2021 budget documents for the first time in more than six years. The Air Force has kept all details about the Next-Generation Air Dominance (NGAD) program highly secret since 2016, but there was a brief, two-year window in 2014-15 when senior defense officials provided information about the underlying technology development efforts.

The NGAP was first referenced in testimony by Alan Shaffer before House Armed Services Committee in March 2014. Shaffer is now the deputy to Ellen Lord, undersecretary of defense for acquisition and sustainment. Six years ago, he was the principal deputy to the director for research and engineering. In that role, Shaffer introduced the NGAP as an enabler to the NGAD program, along with another, complementary initiative focused on new airframes.

“This program will develop and fly two X-plane prototypes that demonstrate advanced technologies for future aircraft,” Shaffer said in 2014. “Teams will compete to produce the X-plane prototypes, one focused on future Navy operational capabilities, and the other on future Air Force operational capabilities.”

A year later, Frank Kendall, then undersecretary of defense for acquisition, technology and logistics, elaborated on the Aerospace Innovation Initiative (AII). The development of the X-planes would be led by DARPA, he said.

“To be competitive, the Navy and the Air Force each will have variants focused on their mission requirements,” Kendall said. “There will be a technology period leading up to development of the prototypes. This will lead to the systems that ultimately will come after the F-35.”

The results of the AII program have not been released or even acknowledged by Air Force or defense officials since 2015, but the initiative suggests that one or two X-plane aircraft could be in testing now.

Kendall's remarks to Congress in 2015 came a year before the Air Force received the results of an Enterprise Capability Collaboration Team on the Air Superiority 2030 Flight Plan, which urged the development of a family of systems anchored by a next-generation fighter to replace the F-22. The Flight Plan prompted the Air Force to commission an analysis of alternatives (AoA) in late 2016. The results of that study were originally scheduled to be released by the end of 2017, but the analysis continued until early 2019.

Meanwhile, a 2015 presentation by the Air Force Research Laboratory showed a notional schedule for the NGAD program; a contract award to launch the engineering and manufacturing development (EMD) phase is set for fiscal 2023. As late as the Air Force's fiscal 2019 budget request, the financial resources devoted to the NGAD appeared to support that schedule: A significant increase in funding starts in fiscal 2023, and $13 billion is set aside overall between fiscal 2019 and 2023. Last year, however, as the results of the AoA study became available, the Air Force appeared to defer the launch of the EMD by at least a few years. The fiscal 2020 budget request included only $6.6 billion for the NGAD from fiscal 2020-24.

Funding for the NGAD and NGAP programs is accounted for separately in Air Force budget documents. The fiscal 2021 budget justification documents reveal that the Air Force spent $106 million for the NGAP in fiscal 2019. Another $224 million is allocated to the NGAP this year. But the program has requested an additional $403 million in fiscal 2021, the budget documents show.

“The Next-Generation Adaptive Propulsion effort consists of four phases: preliminary design, detailed design, engine fabrication and engine assessments,” the Air Force's budget documents state.

“Program deliverables include military adaptive engine detailed design parameters and models, engine hardware (plus spare parts), matured technologies, major rig assessment data (controls, combustor, etc.), program reviews, and technology, affordability and sustainability studies for next generation fighter aircraft,” the documents add.

Germany wants its own version of DARPA, and within the year
By: Sebastian Sprenger COLOGNE, Germany — Germany Defence and Interior ministry officials are pushing for the creation of a new agency this year that will study disruptive technologies relevant to Germany's defense and security. A decision on the way forward is expected “shortly,” a Defence Ministry spokesman told Defense News on Wednesday. Planning is underway to get the green light from the Finance Ministry, a necessary step because the agency would be set up as an “in-house” limited liability corporation, according to the spokesman. If all goes according to plan, insiders believe Cabinet-level consideration of the effort could come as early as September. While there is no official word on the exact timing, the spokesman said creating the agency is firmly on the calendar for 2018. The full name for the outfit is “Agentur für Disruptive Innovationen in der Cybersicherheit und Schlüsseltechnologien,” or ADIC. Its name first popped up in the coalition-government agreement between Chancellor Angela Merkel's Christian Democratic Union and Social Democrats in March. The document postulated that the agency, overseen by the two ministries for interior and exterior security, would help ensure Germany's “technological innovation leadership.” Also requested in that document was the creation of an “IT security fund” that would help protect related key technologies. Defence Minister Ursula von der Leyen referred to the coming agency in a speech in May, equating its purpose to that of the Pentagon's Defense Advanced Research Projects Agency, otherwise known as DARPA. She presented the idea as part of a wider plan toward deep-futures thinking on cybersecurity matters, which also includes a study program at the Bundeswehr University in Munich. Under the relatively new shift to emphasize all things cyber in the German military, the Defence Ministry's Cyber Innovation Hub, created last year, is slated to survey the domestic technology startup scene for ideas with potential military application. Asked by Defense News what status the upcoming agency will accord to the field of artificial intelligence, ministry officials responded that such projects “generally” would be eligible to receive temporary funding if they are deemed relevant to the mission. Much remains unknown about the German military's approach to artificial intelligence, famously dubbed by Russian President Vladimir Putin last year as the technology that holds the key to ruling the world. “The research area of artificial intelligence and potential applications by the Bundeswehr are being substantively reviewed,” the defense spokesman said. Whether the new ADIC or any of the existing organizations inside the Defence Ministry would get involved remains an open question, he added. Some experts fear Germany is falling behind the the United States' and China's enormous efforts in artificial intelligence, though government officials have said they believe the country's talent base and emerging policy framework can ensure success. A whitepaper released Wednesday by the Cabinet agency leading the push on AI, the Ministry of Education and Research, proclaimed the goal of making German-made AI a “seal of quality recognized all over the world.” The document will lead to a more comprehensive strategy by late November. It makes no explicit mention of any military or defense applications. Efforts already exist within the armed forces and the wider government to employ data-mining and predictive-analysis tools, which fall under the broader definition of artificial intelligence. For example, defense officials have touted experiments with a forecasting application developed to predict worldwide crises. Officials also try to play up the Bundeswehr's geekiness in its search for new recruits. A current online marketing campaign showcases the career field of a Bundeswehr University professor employing AI techniques to analyze terror attacks for patterns. https://www.defensenews.com/global/europe/2018/07/18/germany-wants-its-own-version-of-darpa-and-within-the-year

Indian Air Force chief defends Rafale fighter deal against claims of crony capitalism
By: Pierre Tran and Vivek Raghuvanshi NEW DELHI and PARIS — Indian Air Force chief, Air Chief Marshal Birender Singh Dhanoa defended the decision of India's ruling National Democratic Alliance to buy 36 Rafale fightersfrom France, calling it “a game changer" even as the opposition party criticizes the deal. Addressing annual news conference, Dhanoha said: "At the appropriate level, the Indian Air Force was consulted, but it is for the government to choose. It was decided to buy two squadrons through a government to-government deal, to meet up emergency requirements.” India and France signed the €7.8 billion (U.S. $8.99 billion) inter-governmental agreement Sept. 23, under which 36 Rafale fighter aircraft will be procured from Dassault Aviation for Indian Air Force (IAF) in fly away condition. France will invest 30 percent of the total contract value in India's military aeronautics-related research programs and 20 percent into local production of Rafale components to fulfil the mandatory offsets under the deal. The deliveries of Rafale fighters will start this month. India's main opposition party, Indian National Congress, has claimed on several occasions that the Rafale deal is grossly overvalued and tainted by crony capitalism. The Congress said the Modi government had failed to answer several questions on why public sector Hindustan Aeronautics Limited (HAL) had lost the manufacting deal to industrialist Anil Ambani's Reliance Defence Ltd. “The earlier deal for 126 medium multirole combat aircraft reached an impasse during negotiations," Dhanoa said,, referring to a $12 billion medium, multi-role combat aircraft program that was launchced in 2007 but scrapped 10 years later. "We had three options: wait for something good to happen, withdraw the global tender and start over again, or do an emergency purchase. We did an emergency purchase.” Dhanoa called the cost of 36 Rafale was “reasonable and adequate." The latest comments from Dhanoa come after Indian defence minister Nirmala Sitharaman called baseless congressional allegations of a reduction in the number of Rafale jets being purchased from France. Congress has demanded the government explain why instead of 126 Rafale fighter jets, only 36 are being purchased if they were cheaper under the NDA deal than the prior deal. Sitharaman is expected to hold the first annual defence ministers dialogue with her counterpart Florence Parly in Paris Oct. 12-13, as the two countries seek to expand bilateral defense and strategic ties. In France, Dassault said the company had picked Reliance as its Indian partner to meet requirements for local offset established by the Indian Defense Procurement Procedure and Make in India policy. The statement followed controversy sparked by remarks by former French president François Hollande, who said the Indian government selected Reliance as the local partner and that the company "had nothing to say on the subject, we had no choice, we took the partner which was presented.” Dassault put out its statement on the deal for 36 Rafale to India Sept, 21 statement, stating that, in accordance with the policy of Make in India, Dassault Aviation decided to make a partnership with India's Reliance Group. https://www.defensenews.com/global/asia-pacific/2018/10/03/indian-air-force-chief-defends-rafale-fighter-deal-against-claims-of-crony-capitalism

Rheinmetall supplies South African National Defence Force with new 40mm medium-velocity ammunition
November 13, 2020 - Rheinmetall is supplying the South African military with new 40mm medium-velocity ammunition, underscoring its role as the world's leading one-stop-shop for 40mm ammunition systems. In October 2020 Rheinmetall Denel Munition officially completed Project Kamogelo on behalf of the South African Department of Defence, Armscor and the South African Army. What makes Project Kamogelo so special is not only the introduction of a new 40mm medium-velocity (MV) weapon system: it also marks the first successful Expedited Armament Acquisition Process (EAAP) project in response to an urgent operational requirement of the South African Army. The South African Army initiated the project in 2016 with the aim of fielding a new grenade launcher and family of 40mm ammunition. Armscor, the nation's arms procurement agency, approved the procurement plan in February 2018, subsequently overseeing testing and evaluation of the Milkor Y4 multi-shot weapon. This involved firing Rheinmetall Denel Munition's less-lethal, low-velocity and medium-velocity ammunition. Particular emphasis was placed on speed and accuracy. The South African Army procured more than 20,000 rounds of medium-velocity ammunition, including high explosive ammunition, high explosive dual-purpose ammunition, practice ammunition, practice tracer ammunition, red phosphorous smoke rounds and orange target marker ammunition. Rheinmetall Denel Munition's medium-velocity ammunition has a maximum range of 800 metres, exceeding conventional extended range low-velocity (LV) variants by up to 375 metres while delivering unparalleled accuracy. The company's ammunition suite currently encompasses nine different MV variants, six of which formed part of this procurement package. “This day marks ... an important milestone in the history of the Department of Defence, in particular the South African Army, as we witness the handing and taking over ceremony of the 40mm medium-velocity grenade launcher,” said Rear Admiral A.A.A. Morris, Chief Director Defence Acquisition Management, Material Division. “We're proud to be able to offer our new medium-velocity 40mm family to our home market, the SANDF. With this solution we offer the soldier a unique product solution: a quick-firing multiple grenade launcher with a standoff range in excess of 800 metres”, said Jan-Patrick Helmsen, CEO of Rheinmetall Denel Munition. Rheinmetall – the leading one-stop-shop for 40mm systems In the infantry toolbox, the versatile 40mm ammunition pallet closes the gap between hand grenade and mortar. It therefore serves as a veritable combat multiplier for infantry and other dismounted troops. Rheinmetall is one of the world's leading suppliers of ammunition, weapon systems and fire control systems and therefore serves as a one-stop-shop for 40mm systems. Widely used today, Rheinmetall's 40mm x 46 low-velocity ammunition (LV, velocity: 78 m/s) is available in many different versions, including HE/fragmentation, shaped charge with fragmentation jacket (HEDP/high explosive dual purpose) as well a number of other service and practice rounds, together with non-lethal payloads such as kinetic impact munitions or irritant. The range of ammunition is constantly being expanded and new capabilities added. With Rheinmetall Denel Munitions's handover, Rheinmetall has taken the first step as the leading maker of new 40mm medium-velocity (MV, ca. 100 m/s) ammunition. The company is currently expanding its MV product. It now includes the new generation of 40mm MV ammunition, which has a maximum effective range of 800 metres, doubling the gunners's operational reach and providing a flatter trajectory for those crucial close-in, accurately placed shots MV ammunition is. Currently undergoing NATO qualification, Rheinmetall's 40mm MV ammunition family will soon be available in service and practice versions. It can be used with the multi-shot grenade launchers Milkor US M32A1 and AV 140. Furthermore, Rheinmetall's 40mm Magazine-Fed Grenade Launcher (MFGL) is currently under development. The Group's 40mm x 53 high-velocity (HV) ammunition reaches a velocity of 240 m/s and has a maximum effective range of 2,200 metres. Here, too, the Group supplies a wide assortment of different cartridges, including newly developed HE and HEDP airburst ammunition programmed by an infrared programming unit. The airburst function also makes this type of ammunition suitable for engaging small unmanned aerial systems. Among other things, it is earmarked for the Bundeswehr's Qualified Air Defence project. Rheinmetall's family of fire control systems enhances combat effectiveness enormously. It provides users with a broad range of enhanced capabilities, increasing the effectiveness of the gunner while maximizing the potential of the host weapon system and the accompanying munitions. The family consists of various fire control solutions, providing increased accuracy and performance: Vingmate FCS 4500 for high-velocity automatic grenade launchers and heavy machine guns, MR-500 and MR-800 for low- and medium-velocity 40mm grenade launchers and Vingmate SL 1000 for shoulder-launched weapons.
