For more than two decades, a joint program office has overseen the development, acquisition, and sustainment of the F-35 Joint Strike Fighter. 
In the next few years, at least part of that could change.
The Senate Armed Services Committee released its markup of the 2022 National Defense Authorization Act on Sept. 22, and in the bill, the panel called for the Department of Defense to transfer sustainment management to the military services for their respective variants by no later than Oct. 1, 2027.
As part of the provision, the Pentagon would be required to submit to Congress by February 2022 a plan for making such a transition, in which the Air Force would be responsible for the F-35A and the Navy for the F-35B and F-35C.

Ancora a proposito della possibilità di una futura rimotorizzazione degli F-35 ... la discussione continua ...
Ora P&W enumera le possibilità che il proprio motore AETP può offrire al velivolo ...

Quote

Pratt & Whitney is testing its new XA101 Adaptive Engine Transition Program powerplant, and expects to conclude testing its two examples by the end of next year, company military engines division president Matthew Bromberg revealed in an interview. 
He expects that two-thirds of the technology developed from AETP could find its way into earlier engines now flying with the Air Force.
The company is “thrilled” to have two options available for the Air Force and F-35 partners to choose from for an upgrade to the fighter’s propulsion system, Bromberg said. 
GE Aviation has developed the XA100 AETP engine as a competitor to Pratt’s version.
Testing of “our first new fighter engine in 30 years … was successful,” Bromberg said. 
The first XA101 and its twin will shuttle back and forth between Pratt’s facilities and the Air Force’s Arnold Engineering Center in Tullahoma, Tenn., for the next year or so, generating more data. 
The Air Force and F-35 Joint Program Office will use the data to help decide whether the F-35 should get an all-new powerplan - one of the AETP engines - or take Pratt up on its offer of an enhanced version of the F135 engine already in the F-35 fighter.
Pratt succeeded in achieving the AETP’s goals, which were to obtain 10 percent improvement in thrust and 25 percent improvements in both fuel efficiency and thermal management, Bromberg said. 
“We know we can do that,” he said.

Nuclear-capable ...

Quote

American deterrence efforts came one step closer to a critical new level when the Air Force proved a stealth fighter is capable of delivering a tactical nuclear weapon inside hostile territory, Air Combat Command confirmed Oct. 4 (*).
The F-35A is the first fifth-generation fighter to near certification as a nuclear-capable platform after completing the first full weapon system demonstration and completing the nuclear design certification process. 
During the demonstration, two F-35s dropped B61-12 Joint Test Assemblies (JTAs), which mimic a real-world tactical gravity nuclear weapon, at the Tonopah Test Range in Nevada.

La Turchia, estromessa da tempo dal programma JSF, intende ora chiedere un risarcimento miliardario agli Stati Uniti ...

Quote

Turkey intends to seek compensation for its removal from a U.S.-led stealth fighter jet program, possibly during a meeting with U.S. President Joe Biden on the margins of a Group of 20 meeting next month, Turkish President Recep Tayyip Erdogan said.
Erdogan, speaking to journalists during a flight back from a meeting with Russian President Vladimir Putin on Wednesday, also said there would be no “turning back” from deal with Russia for Turkey’s acquisition of S-400 advanced missile defense systems. 
That deal led to NATO-member Turkey’s removal from the international program that produces F-35 fighter jets.
Erdogan said he hoped to meet Biden at the G-20 meeting in Rome to discuss the F-35 project, including a $1.4 billion payment Turkey had made before its ouster from the program. 
Another meeting between the Turkish and U.S. leaders could also take place on the sidelines of a November climate conference in Glasgow, Scotland, Erdogan said.

La mossa a sorpresa della Turchia ... ora chiede agli Stati Uniti l'autorizzazione all'acquisto di 40 F-16 nuovi di zecca a titolo di compensazione ...

Quote

Turkey has made a request to the U.S. to buy 40 Lockheed Martin-made F-16 fighter jets and nearly 80 modernization kits for its existing warplanes, as the NATO ally looks to modernize its Air Force after the purchase of F-35 jets fell through, sources familiar with the matter said.
The deal, worth billions, is still working its way through the Foreign Military Sales process which is subject to approval by the U.S. State Department as well as the U.S. Congress which can block deals.
The people spoke on condition of anonymity to discuss the deal.
"As a matter of policy, the Department does not confirm or comment on proposed defense sales or transfers until they have been formally notified to Congress," a spokesperson for the State Department said. 
The Turkish Embassy in Washington declined to comment.

A titolo di compensazione... Un modo come un altro per non dichiarare che il sultano ha fatto una boiata a prendere dei missili russi lasciando la linea caccia col deretano per terra in attesa di un caccia domestico su cui dovranno sputar sangue per farlo funzionare. Finchè ci sarà Erdogan con le sue manie di grandezza, le cose non potranno che andare nella direzione della ricerca della produzione autoctona, con tempistiche e risultati più condizionati dai suoi desideri di allontanamento dall'Occidente, che alle effettive capacità tecniche e industriali del paese in ottica quinta generazione, in cui trovano spazio idee schizofreniche che viaggiano dai Su-35, ai Su-57, passando per gli F-16.

Appello bipartisan al Presidente Biden ...

Quote

A bipartisan group of lawmakers is urging the White House to fully fund the F-35 Lightning II program in the coming years.
But Senate appropriators are raising concerns about maintenance challenges facing the advanced fifth-generation fighter, and this week questioned the need to buy more F-35s right now.
In a Wednesday letter to President Biden (*), 89 lawmakers, including Reps. Marc Veasey, D-Texas, and Mike Turner, R-Ohio, said the United States needs to keep investing in F-35s in the fiscal 2023 Defense Department budget request and the Future Years Defense Plan. 
Veasey and Turner are co-chairs of the congressional Joint Strike Fighter Caucus.
The Pentagon needs to buy at least 100 F-35s for the U.S. military each year, invest in advanced capabilities to stay ahead of threats from adversaries and provide enough funding to sustain the aircraft for decades, the lawmakers wrote in the letter, though they did not spell out specific funding levels.

Purtroppo neanch'io , non essendo nemmeno abbonato.

Ho riportato il titolo , dato che mi sembrava interessante ( tra l'altro si dice che pensionano lo F-16 nel 2022 ).

Mi sembra che i norvegesi stiano correndo un po' troppo , dato che hanno solo 31 - 34 aerei inventariati su una cinquantina ordinati. 

E alcuni di questi sono in USA per l'addestramento. 

 

p.s. : non merito la frusta , sadicone !

Contratti firmati per l'F-35 in Grecia non ci sono...per ora, ma le trattative credo siano comunque a buon punto, anche perchè sbattere fuori gli ambasciatori occidentali che hanno offeso l'ego del sultano (sempre particolarmente attivo nel "disincentivare" l'opposizione interna) e comprare armi russe non è un modo diplomaticamente brillante per ritagliarsi un futuro nella NATO. Avanzar pretese per gli F-16 e mettere un motore americano in un caccia semi-autoctono sono altre bizze che non so a cosa porteranno nel lungo periodo. A giocare col bastone e la carota si rischia di farsi male...e infatti la lira turca va a picco con un inflazione del 20%...Di solito quando le cose in casa vanno male i dittat.. ehm... i governanti usano la politica estera..."disinvolta" come diversivo.

In questo quadro è evidente che il ruolo della Turchia per la difesa del Mediterraneo orientale (sia per installazioni che per fornitura di materiale) verrà sempre più trasferito alla Grecia, che se da un lato spenderà del suo per evidenti ragioni di competizione con la Turchia, dall'altro chiederà prezzi di favore e investimenti.

Ancora a proposito della possibilità di una futura rimotorizzazione degli F-35 ... interviene l'Amministratore Delegato di Raytheon Technologies che sostiene che l'Air Force potrebbe non essere in grado di permettersi un nuovo motore per l'aereo ...

Quote

The Air Force may decide that it can’t afford to build an entirely new, advanced engine for its F-35A Lightning II fighter jet, the Raytheon Technologies chief executive said Tuesday.
In 2016, the Air Force awarded Raytheon-owned Pratt & Whitney and General Electric Aviation each a billion-dollar contract to develop a new F-35A engine under the Adaptive Engine Transition Program. 
This engine is intended to deliver better fuel efficiency and thrust by using a third stream of air.
However, Raytheon CEO Greg Hayes said in a call with analysts Tuesday morning paying for the new adaptive engine will be a “tough putt” for the Air Force.
Because the adaptive engine could not be used in the F-35B, the Marine Corps’ vertical takeoff and landing variant or the Navy’s carrier-based F-35C, Hayes said the Air Force would bear its entire development cost.
GE said on its website that while its engine is still in testing, it has been designed to be used in both the F-35A and F-35C variants.

Ci vorrebbe la palla di vetro per sapere cosa faranno considerato che parliamo di anni e non mesi.

Penso comunque che varianti dell’attuale motore siano quanto meno indispensabili per garantire la potenza elettrica necessaria ai futuri sviluppi. Sappiamo già che questo sarà abbinato a minori consumi e maggiore spinta, anche se non certo comparabili con quanto ottenibile con il motore adattivo di nuova generazione, che a questo punto andrebbe sul caccia di sesta generazione.

Spesso e volentieri un velivolo nasce e muore con il motore originario magari abbinato e un suo competitor più o meno coevo, come successo per l’F-15 e l’F-16 che adottavano versioni sempre più evolute di F100 ed F110.

L’F136 è stato però affossato da Obama, per cui non ci sarà una sana gara al rialzo fra P&W e GE per accaparrarsi i contratti, ma considerato che l’F-35 rimarrà in produzione per anni e verrà esportato anche quando il caccia di sesta generazione sarà magari inarrivabile, non si può escludere uno step successivo con la rimotorizzazione, anche se gli elevati costi di integrazione bisognerà comunque che qualcuno li affronti.

Nuovamente a proposito della possibilità di una futura rimotorizzazione degli F-35 ... General Electric sponsorizza il proprio prodotto ...

Quote

Fighter jet engines are an inherent compromise. 
If you want more power, you pay by giving up range. 
Want more range? 
It’s going to cost you in power. 
Each generation of jet engines has dealt with this unbreakable rule.
But maybe there really is another way to meet that challenge.
GE’s work in the Air Force’s Adaptive Engine Technology Program overcomes that inherent trade-off by incorporating the ability to change the power dynamics on the fly. 
Its XA100 engine can reconfigure itself in flight to produce power of greater efficiency.

Stati Uniti, Turchia, F-35 e la discussa richiesta di acquisto degli F-16 ... le schermàglie continuano ...

Quote

Turkish President Recep Tayyip Erdogan told journalists on his return home from the G20 summit in Rome on Oct. 31 that President Joe Biden had told Erdogan that Biden would do “his best” to help usher through a $6 billion sale of F-16 fighters and modernization kits, according to reports.
A much-anticipated meeting between Biden and Erdogan comes after months of tension regarding Turkey’s possession and use of the Russian S-400 missile defense system. 
Speculation remains that Turkey will turn to further Russian military sales, to include fighter planes, after the NATO ally was officially kicked out of the F-35 program in September over concerns the S-400 would be used to study vulnerabilities in the fifth-generation fighter.
A State Department spokesperson declined to comment further Nov. 2, referring questions to the White House. 
The White House did not immediately respond to an inquiry.
