發展

[编辑]

AT-802U 天空守望者是由AT-802改裝而成,用於美國特種作戰司令部的武裝守望測試。AT-802本身已經有一個用於根除古柯葉作物的武裝版本,因此已經配備了輕型複合彈道裝甲發動機艙和駕駛艙,稱為“浴缸(bathtub)”。擋風玻璃採用平坦的防彈玻璃面板。 駕駛艙採用鋼管框架設計,作為防滾架,可支撐飛機的整個重量。[4]

該飛機的設計不適用彈射座椅。燃油管路和油箱具有自密封功能,並能緊急拋棄燃油。[4]約束裝置包括配備安全氣囊的 5 點式安全帶。前排和後座椅均設有基本的飛行控制裝置。與大多數現代飛機不同,該機有尾輪配置,適合在嚴苛且未經改進的簡易機場降落。

AT-802U專為快速部署而設計,可在一天內拆卸並裝入C-17中,[5]並且可在一天內組裝完成。

2022年8月1日,Air Tractor和L3Harris獲得了一份價值30億美元,共計75架飛機的合約。該合約包括1.7億美元的預付款,其餘部分在機隊交付時支付。該飛機分兩個階段建造;機身由位於德克薩斯州奧爾尼英语Olney, Texas的Air Tractor製造,裝甲和武器系統由奧克拉荷馬州土爾沙的L3Harris負責。[6]該機將會取代U-28A Draco[7]

AT-802U於2022年底正式命名為 OA-1K。[8]
