Powered by a 20-hp Righter engine to a top speed of 140 mph, the Radioplane OQ-14 served as an aerial target in the years after World War II. Launched from a catapult, it landed by parachute. By 1954, improved models superseded the OQ-14, making it obsolete. This aircraft can be found hanging in Building 2's Korean War Gallery.

OQ-14/TDD-3/TDD-4. Radioplane's model RP-8A was a significantly improved OQ-3/TDD-2 and was first flown in July 1944. It was of heavier construction and had a more powerful O-45-1 engine, rated at 16 kW (22 hp). Compared to the OQ-3, the RP-8A also had a longer fuselage, a shorter wingspan, and wings set flush with the fuselage.

The Radioplane OQ-2 was the first mass-produced UAV or drone in the United States, manufactured by the Radioplane Company. A follow-on version, the OQ-3, became the most widely used target drone in US service, with over 9,400 being built during World War II. The OQ-2 was originally a radio controlled aircraft model designed by Walter Righter.

Variants followed the OQ-2, including the OQ-3/TDD-2 and OQ-14/TDD-3. An uncomplicated design, the OQ-2 drew its power from a two stroke, two-cylinder, six-horsepower engine, which turned contra rotating propellers. It came equipped with a Bendix radio control system.

OQ-2是一款結構簡單的無人機，採用一具雙缸二衝程活塞發動機，驅動兩個反向旋轉的螺旋槳，無線電控制系統由 班迪克斯公司 （英语：Bendix Corporation） 製造。 OQ-2只能通過彈射發射，假若沒有被擊落，則通過降落傘回收（只有OQ-2有起落架，藉由降落傘緩衝著陸，而後所有的型號都放棄起落架）。 1945年6月26日，陸軍攝影師 大衛·康諾弗 （英语：David Conover） 在工廠中遇見了一位名叫 諾瑪·珍·莫滕森 的年輕女工人，鑑於其出色的外貌，康諾佛在工廠中替莫藤森 …
