By Steve Trimble Pratt & Whitney's F100 (pictured) is designed to be interchangeable with GE Aviation's F110 as the engine for the Boeing F-15 fleet. A jet engine maker is pressuring the U.S. Defense Department to scrap a plan to award a sole-source contract to a rival for a fleet of new fighters and investigate the opportunity for performance and cost improvements yielded by a competitive selection process. If that narrative sounds familiar, it is because it echoes a role GE Aviation played for more than 40 years, which included a successful bid in the 1980s to launch the “Great Engine War” over the F-15 and F-16 fleets and a failed campaign that ended almost a decade ago to establish the F136 as the alternate engine for the F-35. This time, however, the roles are reversed. Pratt & Whitney, which waged fierce lobbying campaigns against competitive engine policies for the F-15, F-16 and F-35, has switched sides in the debate. In response to the U.S. Air Force's decision to field the F-15EX into production powered solely by GE F110 engines, Pratt has filed two protests with the Government Accountability Office (GAO), which is scheduled to render judgments on both cases by early July. The Air Force sided with GE during the Great Engine War in 1984. Seeking to lower costs and motivate Pratt to resolve stall-stagnation problems with the original F100, the Air Force decided that year to split the engine contract for the F-15 and F-16 between GE's F110 and Pratt's F100. Thirty-six years later, the Air Force now worries about the schedule impact if the GAO sustains either or both of Pratt's protests of the F-15EX engine. Service officials decided to acquire the F-15EX after concluding the F-15C/Ds were too costly to sustain and because it would take too long for the Pratt F135-powered F-35A to replace all of them. Pratt's protests threaten to disrupt that schedule and erode the Air Force's original business case for the F-15EX. “If we have to do an engine competition, it will add time—2-3 years,” said Will Roper, assistant secretary of the Air Force for Acquisition, Technology and Logistics, testifying before the House Armed Services Committee on March 10. Only a decade ago, Pratt welcomed a vote by Congress in 2010 to cancel funding for the F-35 program's alternate engine, along with a decision by GE and Rolls-Royce a year later to abandon a plan to self-fund the certification of the F136. But Pratt now embraces the potential benefits of an engine competition for the F-15EX. “Our government supports competition at all levels, and we're interested in providing the F100 as a competitive alternative,” Pratt Military Engines President Matthew Bromberg told Aviation Week. “If we're not competitive in terms of capability, schedule [and] price, I get it. But after the U.S. government spent all this money creating two engines for the F-15 and F-16 platforms, why would it then not compete a 450-engine program?” Asked if the existing F100 would require additional development to meet the Air Force's requirements for the F-15EX, Bromberg replied that he cannot answer that question in the absence of a competitive process that allows Pratt access to the specifications. He also noted that the F100 exclusively powers the Air Force's existing fleet of F-15Es. The F100 and F110 were designed to fit interchangeably in the F-15, although the heavily modified Saudi Arabian F-15SA and the Qatari F-15QA from which the F-15EX was derived are exclusively powered by GE's engine. The GAO does not release complaints filed by protesters up front, but it does release the full text of decisions. It is not clear why Pratt filed two separate protests on the sole-source decision for the GE engine on the F-15EX, but Bromberg advised not reading too much into it. “I'd like to obviously be able to discuss them, but I can't because it's a legal process,” Bromberg said. “I would really view them as a single protest on a single procurement action, and that is a lack of competition.” https://aviationweek.com/defense-space/aircraft-propulsion/possible-new-engine-war-recasts-pratt-champion-competition

La ministre des Armées, Florence Parly, accorde une interview à La Tribune. Elle aborde notamment le programme SCAF, soulignant : « les négociations qui sont aujourd'hui en phase finale concernent la réalisation de travaux qui se dérouleront sur la période 2021-2027 et qui visent à mettre en vol un démonstrateur commun à cet horizon. C'est un jalon majeur pour assurer une entrée en service d'un nouvel avion opérationnel en 2040 ». Au sujet du Rafale, la ministre se félicite du choix récent de l'avion de combat de Dassault Aviation par la Grèce et l'Egypte, rappelant que « d'autres compétitions sont encore en cours ». Ces contrats représentent « une bonne nouvelle en termes de visibilité pour la continuité de la chaîne industrielle de Dassault Aviation, Safran et Thales et les plus de 500 sous-traitants, PME et ETI, de l'écosystème Rafale. Nous pouvons placer nos commandes nationales dans un échéancier cohérent au plan opérationnel et par rapport à ce que nous avions budgété ». En matière d'exportations, « l'année 2021 sera exceptionnelle, elle l'est déjà avec 48 Rafale exportés. La dynamique est bonne », souligne la ministre. Florence Parly se félicite par ailleurs de l'attention croissante portée à la souveraineté européenne en matière de défense : l'Europe « commence à s'interroger sur la prise de participation et le rachat de groupes européens par les groupes chinois notamment », estime-t-elle.
