Two F-35A Lightning II aircraft recently released B61-12 Joint Test Assemblies (JTAs) during the F-35A’s first Full Weapon System Demonstration, completing the final flight test exercise of the nuclear design certification process.
The 422d and 59th Test and Evaluation Squadrons led Air Combat Command’s portion of the test effort, with Airmen from the 57th Aircraft Maintenance Squadron, 926th Aircraft Maintenance Squadron and Bolt Aircraft Maintenance Unit leading all maintenance efforts. Once airborne, test pilots flew to the Tonopah Test Range and released two B61-12 JTAs from operationally realistic flight envelopes. This event was the first release of the most representative B61-12 test asset from an operationally-representative F-35A.
“The B61 series weapons are tactical gravity nuclear weapons that can be used on Dual Capable Aircraft like the F-15E and F-16C/D,” said Lt. Col Daniel Jackson, division chief, Headquarters ACC Strategic Deterrence and Nuclear Integration. “Having a 5th Generation DCA fighter aircraft with this capability brings an entirely new strategic-level capability that strengthens our nation’s nuclear deterrence mission."
The nuclear certification is broken into two phases: nuclear design certification and nuclear operational certification. This test is considered the graduation flight test exercise for the F-35A nuclear design certification and concludes on-aircraft testing for the initial nuclear certification effort. The test data received from this event is currently under analysis and review by the Department of Defense and Department of Energy to ensure the F-35A and B61-12 JTAs performed correctly throughout all phases of the operation.
“The B-2 bomber was the prominent nuclear capable stealth aircraft,” said Jackson. “Adding ‘nuclear capable’ to a 5th-Gen fighter that already brings several conventional-level capabilities to the table adds strategic-level implication to this jet.”
No date has been released for full F-35A nuclear certification in support of real-world operations. The successful completion of this test covers a critical part of the nuclear certification process and ensures the F-35A will remain on track for future timelines.
Not all aircraft will become nuclear-capable upon full certification in support of real-world operations. Only those units with a nuclear mission will be given the hardware and manpower necessary to configure and maintain nuclear capable F-35s.

También le he dado vueltas a esto...
Creo que lo ideal es cambiar todos los A y C (las ganancias de tiempo de CAP y alcance son demasiado jugosas para la Navy) y el B con el F135+ que a saber cual se elegirá y quien lo hará si el "me quedo como estoy pero llego mas lejos" o el "tengo mas potencia que antes". Lo que no habla aquí es que pensarán los clientes internacionales con el A o si los del B cambian el motor a futuro. Sería en el momento del paso al Block4 pero a saber cuanto les costará si además incluyes un cambio de motor que costará una salvajada. Aunque el motor seguro que se puede reutilizar de alguna manera para repuestos, upgrade o qué se yo.

Y los Marines también al usar el F-35C.
Luego a los clientes europeos, no les va a suponer gran cosa sobre todo a países tipo Holanda, Bélgica, se quedarán con las mejoras en el propulsor actual y listo. Pero a los japoneses, coreanos, australianos ese plus en rango de combate que tendrá el AETP sobre el F135 sí les va a venir muy bien y que además al ser un propulsor nuevo, tendrá una capacidad de evolución significativa sobre el actual F135. Ni que decir que si al final sale adelante, veremos como la Navy y la USAF van retrasando sus pedidos de los actuales F-35 con el actual propulsor, lo que sería positivo para clientes extranjeros a la hora de recibir éstos con más antelación que la prevista inicialmente.
Quién ha hablado de deficiencias cinéticas?
Que el Block 4 con el incremento de electrónica, EW y capacidad de procesamiento se esta comiendo el margen de potencia y refrigeración del F-135 es un hecho
Pero a los japoneses, coreanos, australianos ese plus en rango de combate que tendrá el AETP sobre el F135 sí les va a venir muy bien
The recent trial, during Exercise Talisman Sabre 21, involved an RAAF F-35A that was engaged in a pre-delivery acceptance flight in the US, together with a Virtual Aegis Weapons System (VAWS) on the ground at Fort Worth, Texas. During its acceptance flight, the F-35 was utilised as an airborne sensor platform and used its on-board Multi-Function Advanced Data Link (MADL) capability to provide weapons’ quality target data to VAWS. The targeting data was then relayed via the US Government communications network to a Battle Management Centre in Hawaii, and on to RAAF Base Williamtown.
From Williamtown, the data was relayed to units on the ground in the TS21 exercise area to engage the simulated target.
Lockheed Martin says it has been working with US Indo-Pacific Command since 2019 on experimentation work to enhance “kill webs” of multiple sensors that collect, prioritise and share data to provide a fused picture for commanders.
“The demonstrations, conducted in partnership with the US Government showcased the F-35 as a successful sensor and shooter in the role and most recently in its first live collaboration with the Australian Defence Force, reinforcing the strength of the alliance,” Lockheed Martin F-35 Combat Air Australia Lead Chris Widerstrom said.
“Indo-PACOM had a requirement as part of Talisman Sabre 21 to collect live weapons quality sensor information from the F-35 and transmit that data via MADL to the greater all-domain operations. Whether to ground-based missile defence systems, or airborne early warning and control (AEW&C) aircraft like the E-7A Wedgetail, representing the ability to distribute and share that information to all participants.”
The trial represented the first ever live sharing of MADL data with a non-US participant and the information received from the F-35 was the only data used to provide the targeting solution to forces on the ground across the Pacific, in real time.
“The VAWS assigned the weapons and then it was passed to a field artillery system through command and control networks and that then enabled the countering of that particular threat by surface to air missile systems,” explained Lockheed Martin Australia Business Development Directory, Rotary Wing Systems Neale Prescott.
“We also had the ability then to direct fire against maritime targets, the purpose was to show that targeting information from an F-35 can be fed into a fire control system that has the necessary weapons to counter complex threats. The weapons assignment is based on who has the greatest chance of conducting the intercept – whether it’s a ship, aircraft or land-based strike asset - and you’re getting that data out in real time.”

“We know we have a demand,” and the Block 4 version of the F-35 will need improved performance from the F135 engine, Fick said. Although the first three capability increments of Block 4 can function with the existing engine, “we know that, going beyond that, we need to do something different,” and the all-up Block 4 can’t fully exploit its new capabilities without more power.
To meet the need for more power, Fick said his office is working closely with Pratt & Whitney and the Pentagon to develop a “family of options” for how to give the fighter more engine power. “We need to start … to put a solution set in place to give us the power and cooling we need” for the upgraded version of the fighter.
He noted that Pratt & Whitney has released information about the Enhanced Engine Program—EEP 25 and EEP 25+—which are “re-coring efforts” to improve the F135.

Just increments capabilities will eat into margins. More EW antennas are coming with block 4, radar enhancements are in Blk 4 and planned for the future. More computing etc. All of this would chew up margins. This before any big ticket items like HEL are introduced.

La solución se llama condensador de fluzo. En serio, se van a tener que plantear algo curioso, y con un monomotor no se yo. Quieren muchas cosas, al final van a tener que elegir que llevan y que no, que usan y que no. Para los lasers se pueden plantear supercondensadores, que ya hay cosas rarunas interesantes para ellos. Si, tienen tiempos de carga, pero funcionarían, pero ocuparían mas sitio de no se sabe donde para ponerlos.
El Block 4 ya se come los márgenes actuales:
En esa categoria de 10-50 kW tampoco creo que haya mucho problema otra cosa es integrarlo en una barquilla stealth y esas cosas.
