En este foro se postean constantemente por aficionados a la temática militar, noticias fabricadas por grupos antimilitaristas, o lobbies con intereses industriales, por la sencilla razón de que la noticia coincide con sus fobias. Y se hace constantemente.
En cualquier otro foro, es una actividad que sería considerado trolling. Aquí se permite y se reciben quejas porque se ignora ese tipo de noticias y de foreros.
Lo cierto es que ni es la unica noticia al respecto, ni es la primera vez que se publican esa noticia, ni es secreto lo que se pone ahi, ni hay que recurrir a otra cosa que no sea releerse el tema en, creo recordar, el hilo del F35.

· Adaptive Engine Transition Program (AETP): The Air Force is sponsoring this approach, which would result in an entirely new engine for the U.S. fleet of F-35As and F-35Cs. Air Force officials told us that the F-35 is being flown harder than originally anticipated, and an upgraded engine is imperative for meeting increasing demands. AETP aims to produce adaptive engines that provide increased thrust during combat conditions and increased fuel efficiency during cruise conditions. Fielding such engines would enable air power with increased range and additional cooling air for thermal management.
However, according to F-35 Joint Program Office officials, this option would pose three challenges that will affect engine life-cycle costs. First, the F-35C aircraft would likely need some sort of modification so that the new engine could be placed in the aircraft. Second, a new engine would present sustainment challenges as the program would have two different engines to sustain—one for F-35As and F-35Cs, and another for F-35Bs—likely requiring changes to the existing infrastructure that supports engine sustainment. Third, this approach will not work for the F-35B variant, according to F-35 Joint Program Office officials. Therefore, if an engine modernization is a requirement for all three variants—F-35A, F-35B, and F-35C—and AETP is selected for the F-35A and F-35C, then another engine modernization effort would still be required for the F-35B. According to program officials, this would result in two separate engine development efforts and have an effect on sustainment strategies and sustainment costs due to the fleet of F-35s operating two unique engines.

The NDAA for Fiscal Year 2022 directed DOD to take actions to plan for F-35 engine modernization. Specifically, the NDAA directed:
· The Air Force, within 14 days after the date of submission to Congress of the President’s budget for fiscal year 2023, to provide details of a competitive acquisition strategy for the integration of an AETP engine into the F-35A aircraft. The Air Force also has to develop a plan for implementing that strategy, including beginning to retrofit all F-35As with that engine no later than fiscal year 2027.
· The Navy, within 14 days after the date of submission to Congress of the President’s budget for fiscal year 2023, to report on the integration of an advanced engine—either one derived from the AETP or from prior efforts associated with the current F-35 engine—into the F–35B and F-35C. This report would include an assessment of the effects of integrating an advanced engine on combat effectiveness and sustainment costs, among other things. Based on its assessment, the Navy is also required to submit a competitive acquisition strategy and implementation plan for integrating an advanced engine into the F35B and F-35C fleets, beginning no later than fiscal year 2027.
