The cockpit uses an unusual double pane windscreen and side-by-side seating arrangement in which the pilot sits in the left seat, while the bombardier/navigator sits to the right and slightly below. This feature was initially included on prototype aircraft, but was removed from the design during flight testing. The jet nozzles were originally designed to swivel downwards for shorter takeoffs and landings. He later played a lead role in the design of the Grumman F-14 Tomcat and the Lunar Excursion Module. The A-6's design team was led by Lawrence Mead, Jr. The prototype YA2F-1 made the Intruder's first flight on 19 April 1960. The company was awarded a contract for the development of the A2F-1 in February 1958. Navy announced the selection of Grumman on 2 January 1958. Following evaluation of the bids, the U.S. Proposals were submitted by Bell, Boeing, Douglas, Grumman, Lockheed, Martin, North American, and Vought. It released a request for proposals (RFP) in February 1957.
Navy published an operational requirement document for it in October 1956. YA2F-1 showing the original tilting tailpipesįollowing the good showing of the propeller-driven AD-6/7 Skyraider in the Korean War, the United States Navy issued preliminary requirements in 1955 for an all-weather carrier-based attack aircraft.
