Operational F-35A fires cannon for first time
By George Allison - August 16, 2018



Pilots from the United States Air Force 388th Fighter Wing’s 4th Fighter Squadron were the first operational unit to fire the F-35As 25mm cannon in a strafing run during training.

According to the US Air Force, the two-ship formation fired on two sets of ground targets on the Utah Test and Training range Aug. 13. Loading and firing the cannon was one of the few capabilities Airmen in the 388th and 419th FWs had yet to demonstrate.

Lockheed Martin say that F-35As internal cannon allows the aircraft to maintain stealth against air adversaries as well as fire more accurately on ground targets, giving pilots more tactical flexibility.

For the F-35A, 180 rounds can be housed in the gun’s linkless ammunition handling system. For the F-35B and F-35C, they both rely on an external gun pod carrying the GAU-22. The GAU-22/A uses a 25mm shell, which is significantly more powerful than what the F-16 the F-15E, F-15C use — all of those aircraft use a 20mm shell.

On June the 9th 2015, a test F-35A shot its first salvos from its four-barrel GAU-22/A Gatling gun.

Bom lembrar que o Único F35 que leva canhão internamente e o A por conta da USAF nunca ter esquecido os problemas que tiveram com os F4.

Para o papel do ST a usaf está criando o OA-X.

Não falei que acho errado qualquer caça ter canhão, nem que seja em pod (que existe para F-35B/C, aliás), embora seja pouco crente em sua utilidade. Acontece que li - em papel - sobre um estudo feito no final dos anos 80 com Pilotos de Caça da OTAN, de onde emergiu um dado curioso: a grande maioria (quase todos, na verdade) deixava claro que hesitaria E MUITO em disparar seu último AAM em um combate se isso significasse ficar completamente desarmado a partir daí. O estudo de que falei foi citado numa matéria em revista - papel outra vez* - especializada em Aviação, no contexto de um longo artigo sobre o então "FX dos EUA" - que resultou no F-22 - como justificativa para a caríssima instalação de canhão numa aeronave supostamente indetectável. Apenas isso.


* - Li isso no começo dos anos 90, época em que, ao contrário daí, PC aqui era coisa de rico, com a secretária particular boazuda do papai usando como máquina de escrever de luxo, sem precisar daquele vidrinho de Corretor, e o filhinho dele para jogar Tetris, Mário, Donkey Kong e outras coisas avançadíssimas para a época. Internet nem se fala, era só discada e paga, ainda por cima, e isso num País onde ter uma simples linha telefônica já era ostentação de riqueza. Sendo eu parte da pobraiada, tinha que me contentar em comprar livros e revistas, em Português e Inglês; não é por nada que lembro de montes de informações mas não sei sequer em qual idioma li, muito menos qual revista ou livro...

Só estava tentando mostrar que existem diversas opiniões sobre o uso de canhões e tal coisa afetou o F-35 de modo que a USN e os Marines só vão usar canhão em "Pods" e quem comprar o F-35A leva canhão "orgânico".

Hoje em dia por mais estranho que possa parecer a "Geração Video Game" de pilotos adora mísseis mais do que canhões. Se você vai conversar com eles, todo mundo fica empolgado com os mísseis e o que eles fazem por conta de mira no capacete, etc.

A geração "Pós Vietnam" foi doutrinada a usar canhão por conta da alta falha dos mísseis.

O advento do MIG-39 AA-11 e o HMD mudou tudo isso. Ninguem quer chegar perto o suficiente para brincar de WWII, mas para quem chegar perto e tem o F-35 A, fica aí o canhão.

The F-35 Is the Wrong Choice for Belgium
The stealth fighter is complex, expensive and unreliable

WIB AIR October 30, 2018 David Axe

Belgium reportedly has chosen the American-made F-35 to replace its old F-16s.

The F-35 is a technological marvel, with radar-absorbing skin coatings that help it to avoid detection.


But it’s also complex, expensive and unreliable. Unable to fly as frequently as the F-16 can do, and too expensive to buy in large numbers, the F-35 despite its impressive technology actually represents a backward step for the Belgian air force.

In buying a small number of F-35s to replace a much larger fleet of F-16s, Belgium is repeating the mistake that the The Netherlands and Denmark made years earlier when they, too, chose the F-35 over a less expensive fighter such as the Gripen or even an upgraded F-16.


News agency Belga first reported the Lockheed Martin-made F-35’s victory over the Eurofighter — a joint British, German, Italian and Spanish warplane — in a long-running competition to replace more than 50 F-16s that Belgium acquired in the 1980s and upgraded with new weapons and software in the early 2000s.

Belgium reportedly will buy just 34 F-35s for $4.1 billion, with deliveries beginning in 2023. The air force operated 56 F-16s, also built by Lockheed, until an accident in early October that resulted in one F-16 firing its gun during maintenance, destroying a second F-16 and damaging a third.

A new F-16 with the latest enhancements costs around $70 million. By contrast, each F-35 sets back taxpayers $120 million.
But maintenance costs account for most of a fighter’s overall expense. Owing to its complexity and the cost of maintenance to its stealth coating, the F-35 costs as much as $28,000 per flight hour, according to Forbes. An F-16 costs just $8,000 per flight hour.

Worse, the F-35 is unreliable. In 2017, just half of the U.S. Air Force’s F-35’s were flyable at any given time, according to official figures that Air Force Times obtained. Seventy percent of single-seat F-16s were flyable.


With just 34 F-35s, Belgium could rapidly run out of air power. Around half might be flyable on any given day. Of those 17 flyable jets, most will be busy on training flights. A handful will be deployable for war. Denmark, which is paying $3.1 billion for 27 F-35s, has stated a goal of deploying four jets to a war zone for a year at a time every three years.
Belgium might manage to deploy five F-35s. And the pilots of those five jets will be less skilled than they might have been had they trained with a more reliable aircraft. Owing in part to the lack of flyable aircraft, U.S. Air Force fighter pilots fly on average just 16 hours per month in 2018, according to Air Force Times.

They need to fly as many as 25 hours a month to maintain fighting skills, according to John Venable, a former F-16 pilot who is now an analyst with the Washington, D.C.-based Heritage Foundation.

F-35s aren’t reliable enough to support intensive training. That could cost lives during wartime. The F-35 “will needlessly spill the blood of far too many of our pilots,” warned Winslow Wheeler, a former analyst with the Center for Defense Information in Washington, D.C.

If Belgium chose a simpler warplane — a new F-16 or Sweden’s Gripen — it could buy more of them and fly them more often than it could do with the F-35. That likely would mean a larger deployable force with better pilots.
In reportedly choosing the F-35, Brussels seems to be betting that the plane’s ability to avoid detection by enemy forces is worth its higher cost and lower reliability. But stealth is just one way a warplane wins in battle. Superior sensors and weapons, pilot prowess and even sheer numbers can also mean the difference between victory and defeat.

Moreover, stealth in essence is a countermeasure targeting specific types of sensors. The F-35 is designed to defeat the kinds of X-band radars that other warplanes and some ground-based air-defenses use to detect enemy jets.

To sidestep the F-35’s design attributes, countries such as Russia, China and Iran are developing radars that emit at lower frequencies — and also adding infrared and visual sensors to their air defenses. It’s for that reason that Pierre Sprey, co-designer of the F-16, called stealth a “scam.”

New sensors could eliminate the F-35’s sole advantage over cheaper and more flyable planes. If and when that happens, Belgium will be left with an air arm that’s smaller and less reliable than it was just a few years earlier, with no technological advantage to justify those liabilities.

The F-35 is the wrong choice for Belgium.

Reino Unido dobra frota de caças F-35 com nova encomenda de 17 aeronaves

Por Fernando Valduga -


Com o novo pedido, o Reino Unido confirmou até o momento a compra de 35 caças F-35B.

O Ministério da Defesa Britânico encomendou um segundo lote de 17 aviões de combate Lockheed Martin F-35B Lightning II. Isso corresponde aos 12º e 14º lotes do programa inicial de produção de baixa taxa (LRIP).

A encomenda de 17 novos aviões F-35B Lightning será entregue entre 2020 e 2022, segundo o Ministério da Defesa, com a Grã-Bretanha fabricando 15% de uma nova encomenda global para 255 aeronaves.

O governo do Reino Unido disse que se comprometeu a adquirir um total de 138 aeronaves durante a vida do programa. O Reino Unido já recebeu 16 jatos F-35B, em uso no Esquadrão 617 da Força Aérea Real em Marham, em Norfolk, e este último pedido elevará o número total de pedidos do Reino Unido para 33. Mais duas aeronaves ainda serão entregues como parte do primeiro pedido, o que significa que as encomendas para o Reino Unido chegam agora a 35 unidades.

“Estou satisfeito em confirmar que estamos duplicando o tamanho da nossa força do F-35 em uma frota formidável de 35 caças furtivos. Esta é outra encomenda massiva no maior programa de defesa da história. Nossas forças armadas e indústria estão desempenhando um papel de liderança no programa F-35?, disse o Secretário de Defesa do Reino Unido, Gavin Williamson. “Estamos agora construindo essa capacidade de mudança do jogo que logo estará pronta para a ação da linha de frente. Este programa está programado para trazer um imenso impulso de £ 35 bilhões para a economia britânica, e será uma boa notícia para nossas empresas que muitos mais jatos estão agora prontos para produção”.



Os 17 jatos encomendados fazem parte de um contrato de US$ 6 bilhões para 255 aeronaves sendo construídas para o programa global F-35. O Departamento de Defesa anunciou que os parceiros do programa F-35 e compradores de vendas militares no estrangeiro (FMS) receberiam um total de 149 aeronaves, como parte de um contrato indefinido com a Lockheed Martin, bem como 106 para as Forças Armadas dos EUA. Dentre as aeronaves internacionais estão incluídos 18 jatos do modelo “B” de decolagem curta e pouso vertical. Além dos britânicas e dos fuzileiros dos EUA, apenas a Itália até agora confirmou a compra desta variante.

O diretor executivo da Defence Equipment and Support (DE&S) do Reino Unido, Sir Simon Bollom, disse: “Como o maior operador de F-35 fora dos EUA, a aquisição de mais 17 aeronaves Lightning reforça nosso compromisso com o programa. Este novo contrato demonstra como nossas Forças Armadas são equipadas pela DE&S com o mais recente equipamento e suporte.”

A notícia deste último pedido ocorre no momento em que as aeronaves F-35B estão embarcadas no HMS Queen Elizabeth para testes de voo nos EUA, que continuam progredindo bem. Os jatos de combate serão tripulados em conjunto pela Royal Air Force e pela Royal Navy e podem operar a partir de terra e mar, formando uma parte vital do Carrier Strike quando operando a partir dos porta-aviões da Classe Queen Elizabeth.

Quem ja beira meio século, como eu, fica triste em ler encomenda de 17 caças para a RAF.
Sou do tempo que a linha de frente da RAF tinha 165 Tornado ADV, 220 Tornado IDS, 160 Phantom F-4, 170 Jaguar e uns 100 Harrier.
Como o mundo mudou.

É um novo contrato para mais 17 caças. O número de caças que eles querem possuir será de 138 F-35 em várias versões.

IAF to supplement F-35 stealth jets with upgraded F-15 IA

In addition to continuing purchasing F-35 multirole stealth fighters, IAF decides to upgrade its dependable F-15 fleet with improved model capable of carrying 13 tons of explosives with advanced avionics.
Alex Fishman

The new F-15 IA was chosen by the IDF and Israel Air Force (IAF) as the new fighter jet to be acquired over the next decade, according to an official announcement Saturday.





The purchase has already been approved by the government, and the first of the aircraft is expected to arrive in Israel as soon as 2023. In the meantime, the IAF will continue purchasing stealth attack aircrafts.
The F-15 IA performance, considered to be superior to the older F-15 aircraft—which has been in IAF use since 1998—is what swayed the decision.
Indeed, the new F-15 can fly longer distances, has higher survivability, more advanced avionic systems, and a much better ordnance-carrying capacity. The jet can carry up to 13 tons of explosives—a capability unmatched by any other attack aircraft.
In the field of air-to-air warfare, the F-15 IA plane is capable of carrying 11 missiles, in addition to 28 heavy, smart bombs for ground targets.
In addition, the aircraft has the capability to carry all the weapons at the IAF’s disposal, including unique Israeli-made missiles, laser and electro-optical systems, and more.
The plane was built by Boeing for the air forces of Qatar and Saudi Arabia, and initially the United States Air Force (USAF), through which the IAF purchased the planes, pressed Israel not to request to purchase the jets.
This is because the Americans had an interest in continuing the development of the stealth F-35 line, which have been acquired by the US military's air and naval forces.
In the past year the USAF has begun to take an interest in the new F-15 IA plane, which gave Israel the green light to enter negotiations for its purchase. It seems as though the Americans have agreed to supply Israel with the new plane on condition that it will continue purchasing the F-35 stealth attack aircrafts.
The IAF emphasized that the new F-15 will not completely replace the F-35 stealth fighter, but is intended to reinforce the systems currently in place to enhance the range of capabilities to an optimal position vis-à-vis its missions—from Iran to Gaza.
According to a document presented by the IDF to outgoing Defense Minister Avigdor Lieberman recently, the IAF intends to complete the purchase of the third stealth squadron at a lower rate—with up to three planes a year. Once the third squadron is complete, approximately in 10 years time, the IAF will have at least 75 F-35 stealth aircraft at its disposal.
The document submitted to Lieberman is one of the last to be approved by the outgoing defense minister. All the IDF's purchases in the US in the coming decade, totaling $38 billion, have been submitted for governmental approval.

Japan to order 100 more F-35 fighters from US

Move comes in response to China's military rise and Trump's pressure
Nikkei staff writers
November 27, 2018 11:26 JST
Japan is set to spend over 1 trillion yen to procure more F-35s like this one.

TOKYO -- Japan is preparing to order another 100 F-35 stealth fighter jets from the U.S. to replace some of its aging F-15s, according to sources.

The plan can be considered a response to China's military buildup, as well as a nod to U.S. President Donald Trump's call for Tokyo to buy more American defense equipment. Japan already intended to procure 42 of the new fighters.

A single F-35 costs more than 10 billion yen ($88.1 million), meaning the additional order would exceed 1 trillion yen.

Japan's government plans to approve the purchase when it adopts new National Defense Program Guidelines at a cabinet meeting in mid-December. It will also include the F-35 order in its medium-term defense program, which covers fiscal 2019 to fiscal 2023. The government wants to obtain 42 F-35s as successors to its F-4s by fiscal 2024.

The 42 fighters Japan originally planned to buy are all F-35As, a conventional takeoff and landing variant. The additional 100 planes would include both the F-35A and F-35B, which is capable of short takeoffs and vertical landings.

At present, Japan deploys about 200 F-15s, roughly half of which cannot be upgraded. The Defense Ministry wants to replace the planes that cannot be upgraded with the 100 F-35s, while enhancing and retaining the remaining F-15s.

To accommodate the F-35Bs, the government intends to revamp the Maritime Self-Defense Force's JS Izumo helicopter carrier to host the fighters.

Japan's neighbors are busy introducing their own advanced military aircraft. China deployed its homegrown J-20 stealth fighter in February, and by 2030 some experts expect the country to build a fleet of more than 250 fifth-generation jets -- as the latest generation of fighters like the F-35 is known.

Russia, too, is expected to introduce its fifth-generation Sukhoi Su-57 in 2019, at the earliest.

To keep up, Tokyo believes it is imperative to significantly increase its procurement of the most sophisticated stealth jets.

At the same time, Trump has repeatedly urged Japan to purchase more American hardware and reduce the trade imbalance between the countries. Buying more of the high-priced fighters is a quick way to do that.

In September, Japanese Prime Minister Shinzo Abe told Trump, "Introducing high-performance equipment, including American [materiel], is important for our country to strengthen its defense capabilities."

Quando o Japão comprou os F-15 nos anos 80 a versão estava mudando do Pre-MSIP para MSIP,

The F-15 Multistage Improvement Program (MSIP) was initiated in February 1983 with the first production MSIP F-15C produced in 1985. Improvements included an upgraded central computer; a Programmable Armament Control Set, allowing for advanced versions of the AIM-7, AIM-9, and AIM-120A missiles; and an expanded Tactical Electronic Warfare System that provides improvements to the ALR-56C radar warning receiver and ALQ-135 countermeasure set. The final 43 F-15Cs included the Hughes APG-70 radar developed for the F-15E; these are sometimes referred as Enhanced Eagles. Earlier MSIP F-15Cs with the APG-63 were upgraded to the APG-63(V)1 to improve maintainability and to perform similar to the APG-70. Existing F-15s were retrofitted with these improvements

Os primeiros lotes cerca de 100 unidades que os japoneses compraram foi da versão Pre-MSIP esta versão tem o computador central mais antigo, e não existe upgrade simples para esta versão, parte da fuselagem interna é diferente, os geradores de energia são mais fracos, se teria de fazer a mesma coisa que foi feita com os F-5 no Brasil reconstruir do zero e o custo disto ultrapassa US$100 milhões a unidade dai a preferencia em trocar pelo F-35.
Os outros 120 da versão C MSIP existe vários pacotes de atualização que pode ser feito de forma mais simples trocando os componentes, eles estão modernizando esta versão ao custo de US$50 milhões a unidade.

O F-35 finalmente iniciou o Teste e Avaliação Operacional Inicial (IOT&E) oficial, que é projetado para medir a eficácia, adequação, letalidade, capacidade de sobrevivência e capacidade geral da missão. A partir desta semana e continuando até o final de junho de 2019, todas as três variantes do Sistema F-35 (A/B/C) serão testadas em campo.
