    The F-35 still has a long way to go before it will be ready for combat. That was the parting message of Michael Gilmore, the now-retired Director of Operational Test and Evaluation, in his last annual report.

    The Joint Strike Fighter Program has already consumed more than $100 billion and nearly 25 years. Just to finish the basic development phase will require at least an extra $1 billion and two more years. Even with this massive investment of time and money, Gilmore told Congress, the Pentagon and the public, “the operational suitability of all variants continues to be less than desired by the Services.”

    Gilmore detailed a range of remaining and sometimes worsening problems with the program, including hundreds of critical performance deficiencies and maintenance problems. He also raised serious questions about whether the Air Force’s F-35A can succeed in either air-to-air or air-to-ground missions, whether the Marine Corps’ F-35B can conduct even rudimentary close air support, and whether the Navy’s F-35C is suitable to operate from aircraft carriers.


    Ahora, tampoco es que el F-35 la tenga particularmente difícil, ya que tiene poca o nula competencia. Los eurodeltas son una generación anteriores, y los cazas rusos y chinos de 5ta generación no sé sabe a ciencia cierta cuántos años de retraso llevan respecto al F-35.

    Electronics used to justify cost — not delivering capabilities

    The F-35 is being sold to the American people based in no small part on its mission systems, the vast array of sophisticated electronics on board the jet. A quick perusal of any of the hagiographic articles about the F-35 will find that they nearly always point to its capabilities to gather massive amounts of information.

    This information is supposed to come through its onboard sensors and the data links to outside networked sources, and then be merged by the F-35’s computer systems to identify and display for the pilot the specific threat, target and accompanying force picture — i.e. “situational awareness.”

    This process is designed to allow the pilot to dominate the battlespace. Based on the actual test performance of these systems during developmental testing, however, it appears the electronics actually interfere with the pilot’s ability to survive and prevail.

    Overall, problems with the F-35’s sensors, computers and software, including creating false targets and reporting inaccurate locations, have been severe enough that test teams at Edwards Air Force Base have rated them “red,” meaning they are unable to perform the combat tasks expected of them.

    One system, the Electro-Optical Targeting System (EOTS), was singled out by pilots as inferior in resolution and range to the systems currently being used on legacy aircraft. EOTS is one of the systems designed to help the F-35 detect and destroy enemy fighters from far enough away to make dogfighting a thing of the past. Mounted close to the nose of the aircraft, it incorporates a television camera, an infrared search and track system, and a laser rangefinder and designator.

    These sensors swivel under computer control to track targets over a wide field of regard and display imagery on the pilot’s helmet visor display.

    But the limitations of EOTS, including image degradation with humidity, force pilots to fly in closer to a target than they had to when using earlier systems just to get a clear enough picture to launch a missile or take a shot.

    The report says the problem is bad enough that F-35 pilots may need to fly in so close to acquire the target that they would have to maneuver away to gain the distance needed for a guided weapon shot. Thus, the system’s limitations can force an attacking F-35 to compromise surprise, allowing the enemy to maneuver to a first-shot opportunity.


    El F-35 obtuvo su IOC hace más de un año, mientras sus rivales todavía están esperando a probar su motor o aviónica definitiva.
    Si se fija todos los reportes que publico son de este año.

    Quizás mi planteamiento sea muy simplista, pero por un lado tienes un avión que aún no logra el desempeño final prometido (eso creo que está más que claro); pero ya tiene más de 200 unidades operando (¿o 250?, no manejo el número exacto al día de hoy), 500 pilotos habilitados en el avión, saliendo de tres líneas de producción, realizando despliegues en Asia y Europa del Este, y mostrando excelentes resultados en ejercicios (según ellos, pero demosle el beneficio de la duda que por lo menos se mide frente a otros aviones).

    Y por el otro, en el caso del Su-57, ¿12? prototipos volando, al parecer recién ahora probando el motor definitivo, una electrónica que es un misterio cómo se comportará, y un cliente potencial (India) que tiene críticas bastante fuertes por el producto. Del J-20, se sabe aún menos, aunque si a los norteamericanos les ha dado dolores de cabeza el EOTS, no quiero ni imaginar a los chinos que hicieron su versión en base a espionaje industrial.

    En resumen, comparamos una realidad regular con dos buenas promesas; y por lo menos para mí lleva las de ganar la realidad regular, simplemente por que es real...

    Saludos
