    Otro articulo que resume muy bien los demás artículos ya posteados:

    The A-10 Warthog Political Battle

    Original plans were to retire the A-10 in 2028. In 2007 the Air Force awarded a $1.1 billion contract for Boeing to replace the fatigued wings of operational A-10s, extending their service life until 2040.

    However, as the wing replacements were still ongoing, the Air Force announced it would axe A-10 squadrons due to budget cuts. In addition to cutting the A-10, thousands of personnel positions were eliminated and flying hours were drastically reduced across the Air Force.

    Air Force leaders had decided that it could no longer sustain a single-role fighter. Multi-role fighters like the F-15E, F-16, and soon the F-35 would pick up duties that the A-10 performed. They argued that it was antiquated, vulnerable to new ground defense systems, and that multi-role aircraft could deliver more precision ordnance than the A-10.

    Army leaders scoffed at this, recognizing the critical difference between the A-10 and the faster jets. The A-10 gets right down “in the weeds” with ground troops in combat. Pilots can more easily identify targets and separate the good guys from the bad guys. Not to mention the psychological impact – its presence is tremendously motivating for friendly forces and destroys the enemy’s will to fight. The Army even considered buying the A-10 Warthog for a very short moment.

    There was a lot more going on behind the scenes. A string of questionable acts by Air Force leaders was revealed in 2015, showing they were being more than disingenuous about the A-10 Warthog.

    In January 2015, Major General James Post told a group of pilots that if any of them went to Congress about the A-10, they would be charged with treason. Post was fired after an investigation ordered by Senator John McCain.
    Later that year, Air Force Chief of Staff General Welsh attempted to justify retiring the A-10s because they were so easy to hit during the first Gulf War. He cited that 70% of A-10s suffered battle damage. Later, a study showed that the number is actually closer to 13%. This glaring disparity was later attributed to the General incorrectly remembering a briefing.
    A video surfaced in 2015, presumably made by Air Force Combat Camera, highlighting the role of the A-10 in combat in Afghanistan. Air Force officials sought to suppress the public release of this short film, as it came out right when Air Force leaders were arguing that the A-10 was becoming obsolete and should step aside to make room for the pricey F-35.

    Also that year, an unnamed Air Force official supplied a reporter at USA Today some unbelievably doctored numbers to paint a picture that the A-10 is responsible for more civilian deaths and fratricide than any other airplane. Date ranges were inconsistent across the reporting and rates were omitted in favor of raw numbers, all incriminating the A-10 for something that other aircraft are more responsible for.

    Future of the A-10 Warthog

    Kills for an A-10 Thunderbolt II, or A-10 WarthogThe A-10’s important role in current operations against ISIL has proven to leaders that there’s really nothing that can fill its shoes right now. Air Force leaders have finally admitted that operational costs of the F-35 are prohibitively high to operate it at the same daily rate that the A-10 is flying. Further, they conceded that the F-35 couldn’t fill the CAS role of the A-10. As a result, the retirement of the A-10 has been put on hold until a “cheap” CAS replacement can be found.

    But it took an act of Congress to bar the Air Force from retiring the A-10 Warthog. In the 2015 defense appropriations bill, Congress allocated money to keep the A-10 flying for at least one more year. The Air Force didn’t fully comply with the intent of this bill. They cut funding for upgrades and moved aircraft into “non-flying” status, reducing the number of aircraft available to fly combat missions contrary to direction from Congress.

    So in the 2016 version of the bill, Congress had to explicitly order the Air Force to not cut manning, move aircraft to storage, or cut maintenance costs.

    The A-10 will continue to lead sortie rates for manned aircraft operations in the Middle East for now. The battle is far from over as the Air Force looks for other ways to kill the A-10 to free up money for the F-35 and drop the CAS mission from Air Force doctrine. As long as Congress keeps intervening, it looks like the A-10 Warthog will be safe from the boneyard for some time to come.

    The Air Force's Rationale For Retiring The A-10 Warthog Is Bullshit

    The fact that the USAF is so willing to throw away 300 of the finest close air support platforms ever invented just to save the cost equivalent of 30 F-35 Joint Strike Fighters is total bullshit and both the American taxpayer and those who bravely fight our wars on the ground should be furious.

    The Air Force wants to "replace" the A-10 some time in the future, hopefully, with something not nearly as "elegant," to use their own words, but still capable of the basic close air support (CAS) mission. Elegant is not a term not usually associated with this brutish killing machine, but there is little doubt that the Warthog accomplishes its mission with almost an artistic flare. This "something" the USAF brass touts is the F-35 Joint Strike Fighter. In the meantime, our soldiers will be left getting close air support from "adequate" high-performance fighter aircraft, Predator and Reaper unmanned systems, and huge aircraft built originally as strategic bombers.

    During an interview with Defense News Air Combat Command chief Michael Hostage stated:

    "I would dearly love it to continue in the inventory because there are tactical problems out there that would be perfectly suited for the A-10. I have other ways to solve that tactical problem. It may not be as elegant as the A-10, but I can still get the job done, but that solution is usable in another level of conflict in which the A-10 is totally useless. It does not make any sense to cut the other program and keep A-10s if I have to give one up for the other. I really save the big bucks when I take an entire [platform] and shut it down because I save the squadrons of those airplanes but I also save the logistics infrastructure, the training infrastructure and all of the overhead."

    The fact that General Hostage acts like he has no choice in the matter when it comes to shutting down the entire A-10 program, which equates to close to 300 aircraft and their support infrastructure, is bogus. Doing so would reportedly save only a measly 1% of the USAF's total yearly budget of close to $110,000,000,000, and that savings would only be programmed over the next few years.

    The A-10 is a national treasure, and the hundreds, if not thousands, of American and allied soldiers it has saved over decades of combat operations will attest to this. Regardless of the Warthog's undeniable effectiveness on the battlefield the aircraft has always been the unwanted straight-winged step child of the USAF. In fact, the boys in blue have tried to kill the A-10 program since its very inception, and have repeated their assassination attempts time and time again. Strangely, these attempts usually come quickly after the aircraft has performed marvelously in combat and has saved the lives of our troops on the ground while taking those of our enemies with great prejudice.

    It would seem that the supersonic, pointy nosed fighter jet culture that has always prevailed in the USAF's top echelon only praises the A-10 when they desperately need it, then when such a time passes, it returns to being their budgetary sacrificial lamb.

    'Billy Madison', todo un clásico.

    Los belgas se quieren dejar estafar:

    Belgium – F-35 Joint Strike Fighter Aircraft

    WASHINGTON, JAN. 18, 2018 - The State Department has made a determination approving a possible Foreign Military Sale to Belgium of thirty-four (34) F-35 Joint Strike Fighter Conventional Take Off and Landing aircraft for an estimated cost of $6.53 billion. The Defense Security Cooperation Agency delivered the required certification notifying Congress of this possible sale today.

    The Government of Belgium has requested to buy thirty-four (34) F-35 Joint Strike Fighter Conventional Take Off and Landing (CTOL) aircraft, and thirty-eight (3 Pratt & Whitney F-135 engines (34 installed, 4 spares). Also included are Electronic Warfare Systems; Command, Control, Communications, Computer and Intelligence/Communications, Navigational, and Identification (C4I/CNI); Autonomic Logistics Global Support System (ALGS); Autonomic Logistics Information System (ALIS); Full Mission Trainer; Weapons Employment Capability, and other Subsystems, Features, and Capabilities; F-35 unique infrared flares; Reprogramming center; F-35 Performance Based Logistics; software development/integration; aircraft ferry and tanker support; support equipment; tools and test equipment; communications equipment; spares and repair parts; personnel training and training equipment; publications and technical documents; U.S. Government and contractor engineering and logistics personnel services; and other related elements of logistics and program support. The estimated total case value is $6.53 billion.

    This proposed sale will contribute to the foreign policy and national security of the United States by helping to improve the security of an ally and partner nation which has been, and continues to be, an important force for political and economic stability in Western Europe.

    This proposed sale of F-35s will provide Belgium with a credible defense capability to deter aggression in the region and ensure interoperability with U.S. forces. The proposed sale will augment Belgium's operational aircraft inventory and enhance its air-to-air and air-to-ground self-defense capability. Belgium will have no difficulty absorbing these aircraft into its armed forces.

    Tontos ellos. Dedíquense a los waffles.

    Default Reality Strikes Back (Yet Again)

    Los "estafados" italianos declaran operacional al F-35 (ese que llamaban "prototipo" en otro hilo) en rol aire-aire.
    The Italian F-35A Stealth Jets Declared Operational In The Air-To-Air Role

    The Italian Air Force F-35A Lightning II have successfully achieved the IOC (Initial Operational Capability) in the air-to-air role.

    The first Italian F-35A Lightning II aircraft assigned to the 13° Gruppo (Squadron) of the 32° Stormo (Wing), based at Amendola air base, in southeastern Italy, have achieved the IOC (Initial Operational Capability), the Italian Air Force has announced.

    Since Mar. 1, 2018, the first five stealth aircraft assigned to the Aeronautica Militare have been supporting the SSSA (Servizio Sorveglianza Spazio Aereo – Air Space Surveillance Service) with a Standard Conventional Load (SCL) that includes the AIM-120C5 AMRAAM (Advanced Medium Range Air-to-Air Missile) missile. This means that, if needed, the 5th generation aircraft can undertake regular QRA (Quick Reaction Alert) shifts or be diverted from a different mission to intercept and identify unknown aircraft.

    Whilts the F-35 is a multirole aircraft (hence an air-to-air capability should not be too surprising) all the Italian Air Force combat planes (including Tornado and AMX fighter bombers as well as the T-346 advanced jet trainers) are required to be fully capable in the air-to-air role to support Italy’s Air Defense.

    The IOC in the air-to-air role comes after a long period of training that has seen the F-35s perform T-Scrambles (Training Scrambles) as well as joint drills with Typhoons, G550 CAEW (Conformal Airborne Early Warning) and T-346 jets. Last year, the Italian Lightnings took part in their first national large scale drills during Vega 2017 multinational joint exercise.

    In December 2016, the Italian Air Force became the very first service to take delivery of the 5th generation stealth jet outside of the U.S. The IOC in the air-to-ground role of the Italian JSF has not been declared yet.
    Nótese lo que implica la declaración de "operacional". La Aeronautica Militare está en capacidad de desplegar sus JSF en turnos regulares de QRA (los desplegarán en Europa del Este como parte de la rotación de fuerzas QRA de la OTAN? ).

    Repito lo que mencioné hace un tiempo: El F-35 tuvo un parto dificil -como es común cuando se desarrolla tecnología de punta, sin precedentes que copiar-, pero a estas alturas ya es necio (y francamente ignorante) sostener que "no funciona". Uno puede tener reservas puntuales (ALIS continua siendo problemático, y OBOGS continua siendo un sistema "temperamental"), pero negar la viabilidad y supremacía del F-35 como sistema de armas -o peor aun, pretender comprarlo con plataformas de cuarta generación- es ya un asunto de fanatismo ideológico.

    Un articulo interesante sobre el "operacional" usando el traductor.

    Todavía no hay línea de llegada a la vista para el programa F-35

    Los aviones furtivos siguen teniendo un rendimiento inferior

    26 de marzo de 2018 Dan Grazier

    Jim Roche, el entonces secretario de la Fuerza Aérea de EE. UU., Hizo un anuncio el 26 de octubre de 2001 , que todos los entusiastas de la aviación habían estado esperando. Se eligió un ganador para diseñar y construir el Joint Strike Fighter.

    Al pueblo estadounidense se le aseguró que el nuevo avión entraría en servicio en 2008 y sería un reemplazo de alto rendimiento para las células del envejecimiento de las fuerzas armadas, mientras que solo costaría entre $ 40 millones y $ 50 millones.

    El F-35 ahora ha entrado en un decimoséptimo año sin precedentes de rediseño continuo, deficiencias en las pruebas, arreglos, retrasos en el cronograma y sobrecostos. Y todavía no está en la línea de meta. Numerosos errores en el camino, desde el hecho de que los dos contratistas competidores, Lockheed Martin y Boeing, enviaron aviones "flyoff" que eran "demostradores de tecnología" crudos y no desarrollados en lugar de seguir la mejor práctica de enviar prototipos completamente funcionales, a negligencia de adquisición concurrente eso ha impedido que los defectos de diseño se descubran hasta después de que se construyeron los modelos de producción, han llevado a donde estamos ahora.

    De acuerdo con el último informe anual del Director, Prueba y Evaluación Operativa, 263 deficiencias de rendimiento y seguridad de "alta prioridad" siguen sin resolverse y no se abordan, y las pruebas de desarrollo -en esencia, las pruebas de laboratorio- están lejos de completarse. Si completan las pruebas, seguramente se encontrarán más deficiencias que deben abordarse antes de que el avión pueda llevar con seguridad a nuestros aviadores y mujeres al combate.

    A pesar de esto, la Oficina del Programa Conjunto F-35 ahora tiene la intención de llamar, de manera bastante arbitraria, el fin de la fase de desarrollo del avión y las pruebas de desarrollo. En lugar de completar el trabajo de desarrollo planificado actualmente, la Oficina del Programa ahora propone sustituir un programa de actualización F-35 vagamente definido llamado "desarrollo y entrega continua de capacidades". El informe DOT & E declara rotundamente que este plan, como se propone, "no es ejecutable". debido a recursos de prueba inadecuados "en los plazos rápidos propuestos.

    No requiere información interna para comprender que el plan propuesto es solo una forma de ocultar grandes retrasos en el desarrollo y sobrecostos, al tiempo que facilita el aumento de compras anuales de producción de F-35 incompletamente desarrollados. Veintitrés F-35 plenamente diseñados y totalmente aptos para el combate deben comenzar las pruebas operativas más importantes y más rigurosas antes de finales de 2018, pero es imposible reparar las 263 deficiencias conocidas de Prioridad 1 y 2 a tiempo. para cumplir ese horario.

    Esto claramente no molesta a los altos funcionarios del Pentágono que están presionando para seguir adelante con la producción a pesar de las deficiencias no resueltas. Ya, 235 de los aviones plagados de deficiencia han sido nominalmente designados como "listos para el combate" y entregados a los escuadrones activos de la Fuerza Aérea y del Cuerpo de Marines. Las consecuencias de este plan para la seguridad y las tácticas efectivas en el entrenamiento de la unidad operacional, y mucho menos en el combate, son desconocidas. Los funcionarios del Departamento de Defensa que aprobaron interrumpir la fase de desarrollo del F-35 deberían, y con suerte lo harían, rendir cuentas cuando surjan las consecuencias inevitables en seguridad, efectividad en el combate y sobrecosto.

    Tal como se anunció inicialmente, y durante el desarrollo del programa, a los contribuyentes se les ha dicho que este sistema exorbitantemente costoso es necesario para combatir amenazas futuras avanzadas. Sin embargo, los resultados de las pruebas muestran que los aviones ya entregados ni siquiera pueden abordar de manera efectiva las amenazas actuales . Eso es un problema.
    El articulo completo da detalles de ese programa y que lo único operacional que puede demostrar ese prototipo es su buena capacidad para ser vendido pero no para cumplir con lo que pretendía ser.
