Designed in 1919, it was powered by a pair of modified Liberty engines driving pusher propellers. The first of the Engineering Division's heavily armored GAX series (ground attack, experimental) aircraft, the ponderous airplane was intended to strafe ground troops while remaining immune to attack from the ground as well as from other enemy aircraft. It was so well armored that its five-ton weight proved excessive. ==Development== Soon after the end of World War I, the US Army sought to explore highly armored and armed specialist ground-attack aircraft. This was a pet project of General William Mitchell. The Army Air Service Engineering Division issued requests for proposals to U.S. aircraft producers on 15 October 1919. There were no designs offered, so the Engineering Division ordered one of its engineers, Isaac M. Laddon, to attempt what the aviation industry clearly considered impossible. His design, designated GAX, first flew at McCook Field on 26 May 1920. The GAX was McCook Field Project P129 and wore AAS serial number 63272.〔Ray Wagner, 1968〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Boeing GA-1」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
