The OQ-2 was originally a small radio controlled aircraft model designed by Walter Righter. The design, along with its engine design, was purchased by actor Reginald Denny, who had demonstrated another model to the US Army in 1940. Calling the new design the RP-2, he demonstrated several updated versions to the Army as the RP-2, RP-3 and RP-4 in 1939. In 1940, the Army placed an order for 53 RP-4s. This small order led to a much bigger 1941 order for the similar RP-5, which became the US Army OQ-2, the OQ meaning a "subscale target". The US Navy also bought the drone, designating it TDD-1, for Target Drone, Denny, 1. Thousands were built, manufactured at the Radioplane plant at the Van Nuys Airport in the Los Angeles metropolitan area. It was at this factory on June 26, 1945 that Army photographer David Conover saw a young woman assembler named Norma Jeane Dougherty, whom he thought had potential as a model. She was photographed in the plant, which led to a screen test for Norma Jeane, who soon changed her name to Marilyn Monroe
Description and variants
The OQ-2 is a simple aircraft, powered by a two-cylinder two-cycle piston engine, providing and driving two contra-rotating propellers. The RC control system was built by Bendix. Launching was by catapult only and recovered by parachute should it survive the target practice. The landing gear was used only on the OQ-2 versions as sold to the Army to cushion the landing by parachute. None of the drones including the improved variants shipped to the Navy had landing gear. The subsequent variants delivered to the Army did not have landing gear. The OQ-2 led to a series of similar but improved variants, with the OQ-3 / TDD-2 and OQ-14 / TDD-3 produced in quantity. A number of other target drones were built by Radioplane and competing companies during the war, most of which never got beyond prototype stage, which accounts for the gaps in the designation sequence between "OQ-3" and "OQ-14". After World War II ended, various experiment were made with Radioplane target drones. In one experiment in 1950, a derivative of the QQ-3 Radioplane drone was used to lay military communication wire. During the war Radioplane manufactured nearly fifteen thousand drones. The company was bought by Northrop in 1952.
