    Default A-12 Avenger II (proposed replacement for A-6 Intruder)

    Grumman Avenger (I)










    reminds me of the Horten Ho 229





    The A-12 Avenger II was an American aircraft program from McDonnell Douglas and General Dynamics intended to be an all-weather, stealth attack replacement for the A-6 Intruder in the United States Navy and Marines. The aircraft suffered numerous problems throughout its development, especially with the materials, and when the projected cost of each aircraft ballooned to an estimated US$165 million, the project was cancelled by then-Secretary of Defense **** Cheney in January 1991.

    Artists' conceptions and mockups of the craft revealed a flying wing design in the shape of an isosceles triangle, with the cockpit situated near the apex of the triangle. The aircraft was designed to have two General Electric F412-GE-D5F2 turbofans (each producing about 13,000 lbf (58 kN) thrust and was equipped to carry up to two AIM-120 AMRAAM missiles, two AGM-88 HARMs and a full complement of air-to-ground ordnance, including Mk 82 bombs or smart bombs in an internal weapons bay. The A-12 gained the nickname "Flying Dorito".

    The cancellation of the project resulted in years of litigation between McDonnell Douglas/General Dynamics and the Department of Defense for breach of contract. The case was still on appeal in the court system as of 2007. [1]

    The Navy shifted to buy the F/A-18E/F Super Hornet, which has replaced the A-7, A-6, and the F-14.

    So tell me, why would they let the public walk up concept plane?

    Nm. It's a fake plane.

    I wonder how the wings folded? They seem thick and awkwardly shaped to allow folding; not to mention the joints necessary would degrade stealth.

    If it was still greenlit, it'd probably only now be in flying prototype stage, and several billion dollars overbudget.

    Very interesting, thanks for posting this B25Hmitchell.

    A misnomer; it's Horten Ho IX, production by Gothaer Waggonfabrik in Oberammagau as the Go 229.

    Would that shape work aerodynamically (sp?), the first Avro Vulcan had a dead straight leading edge but was found to be inferior (for whatever reason) to a cranked leading edge...

    Like all planes with stealth features it would of used computers to provide stable flight and compensate for the aerodynamic disadvantages that stealth design creates as a byproduct.
