Lockheed Martin Corp., Fort Worth, Texas, is awarded an $18,754,263 modification (P00064) to a previously awarded, cost-plus-incentive-fee contract (N0001918C1048). This modification adds scope to provide depot tooling and test equipment in support of establishing the initial depot repair of radio frequency support electronics and multi-function antenna components, to include data processor, array assembly, and antenna control module for the F-35 aircraft for the Air Force, Navy and Marine Corps. Work will be performed in Fort Worth, Texas, and is expected to be completed in January 2026. Fiscal 2023 aircraft procurement (Navy) funds in the amount of $9,377,132; and fiscal 2023 aircraft procurement (Air Force) funds in the amount of $9,377,131 will be obligated at the time of award, none of which will expire at the end of the current fiscal year. The Naval Air Systems Command, Patuxent River, Maryland, is the contracting activity.

No. Lo que se pide no es "empuje", es "potencia eléctrica" y capacidad de refrigeración: https://www.f135enginecoreupgrade.com/n ... ing-system

Collins Aerospace and Pratt & Whitney have unveiled a new power and cooling system for the proposed upgraded F135 engine core, aiming to increase the power output and cooling required for coming F-35 upgrades as the Pentagon considers the future of the Joint Strike Fighter’s powerplant.
The Raytheon Technologies companies say the Emergency Power and Cooling System (EPACS) with the F135 Engine Core Upgrade (ECU) will bring a 7% increase in range and thrust and twice as much cooling. The system is compatible with all F-35 variants and can reach technology readiness level six in 2023, meaning it is ready for a technology demonstration. The company claims it would provide about $40 billion in savings compared to replacing the aircraft’s entire engine.

The current F135 is under heavy strain supporting the F-35’s advanced avionics and issues with thermal management. The Joint Program Office says the Block 3 version of the F-35 produces 30 kW of waste heat from electronics, with that number to grow to 47 kW in Block 4. The current engine is optimized to absorb up to 14 kW of waste heat. Pratt says the current engine can provide the needed power, but it will burn hotter, requiring more maintenance.
“Really what the customer is looking for is more cooling to power these weapons systems … Pratt & Whitney is offering the Engine Core Upgrade because it solves the problem and it does so in the most cost-effective way,” says Jen Latka, vice president of F135 systems at Pratt & Whitney.

Como ves, en realidad hay dos programas. El EPACS para dar más potencia eléctrica y capacidad de refrigeración y el ECU para actualizar las "partes calientes" del motor. El actualizar estas partes traerá un aumento de la potencia motor del 7% en contraste con el 100% de la capacidad de refrigeración. Creo que se ve bien donde se ha puesto el énfasis. En ningún lado se habla de "thrust" o empuje.
