The F-35B, a real success but a severe handicap for the Joint Strike Fighter program

On October 3, 2021, after a year-long modernization program, the Japanese Maritime Self-Defense Forces' assault helicopter carrier Izumo saw the first sight of an F-35B combat aircraft. United States Marine Corps Lightning II take off from its flight deck (main illustration photo), some 76 years after the last plane of the Empire of Japan left the deck of an aircraft carrier of the Imperial Japanese Navy. After the United States, Great Britain and Italy, it is the 4th country to implement Lockheed-Martin's American stealth fighter with vertical or short take-off and landing from an aircraft carrier, corn…

The US Air Force sharpens its strategy to reduce the number of F-35As it will buy

For nearly 15 years, the US Air Force had only one answer to all questions about its fighter fleet, the F-35A. Decked out with quasi-mystical abilities of stealth and combat power, the aircraft had to meet all the challenges they could face in the next 30 years. But since the first pranks of Will Roper, then Director of Developments and Acquisitions of the US Air Force on this program in 2018, until the most recent declarations of General Brown, Chief of Staff of the USAF, and the General Kelly, who commands the American fighter, the reserves of the first air force in the world...

Does the political power of the F-35 program make it unshakeable?

In recent weeks, the F-35 program had suffered the wrath of certain American parliamentarians, who criticized it for its excessive price, particularly in terms of maintenance, and its lack of reliability and availability. For his part, the Chief of Staff of the US Air Force, General Brown, had himself announced that it might be preferable, for the US Air Force, to develop a new device that is less technologically advanced but less expensive and more reliable than the F35 to replace the F-16 fleet currently in service, knowing that the current costs surrounding the F-35 program would not allow the USAF to acquire and implement the…

F35 engine life reduced by overheating issues

Availability of America's next-generation F-35A fighter jet, already far from satisfactory, could shrink further as new issues arise, this time with the coating of the F-135 engine's turbine blades by Pratt & Whitney. Indeed, according to an article published on the Bloomberg information site, it would seem that the engine has an operating temperature higher than forecast, which would cause premature deterioration of the coating of the turbine blades, leading to the appearance of jacks. These defects threatening the integrity of the engine as well as its performance, it is necessary to limit the life of the engine or to undertake very heavy...

The US Air Force requests competitive bids for the F-15EX Advanced Eagle engines

Faced with the delays and operational limitations of the F-35 (especially in terms of range and payload), the American air force seems particularly keen on replacing its oldest F-15C Eagles with… new F-15s. Indeed, if the US Air Force maintains its objective of acquiring 1700 F-35 single-engine aircraft from Lockheed Martin, it also intends to integrate into squadrons one or two hundred F-15EX Advanced Eagle, a new variant of the F-15 Eagle twin-engine from Boeing. Until now, it seemed agreed that the USAF Advanced Eagles would be equipped with the same engines as the latest F-15 variants exported to South Korea, Singapore or…

US Air Force B-52H bombers to exceed 100 years of operational career with new engines

On April 23, the US Air Force issued a draft request for proposal for the acquisition of no less than 608 commercial aircraft engines. This last step before the publication of the call for tenders will allow manufacturers to better prepare their proposals. Although the project is a year late, the US Air Force hopes to make rapid progress on the re-engining program for its B-52H Stratofortress, considered strategic for maintaining its operational capabilities. Evoked since the end of the Cold War, the change of engines of the B-52 has been constantly postponed by the US Air Force, the heavy bomber…
