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. 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. [1]
In 1940, the Army
placed an order for 53 RP-4s (some sources refer to the RP-4 as OQ-1. but that designation was never assigned). 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, who 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. [2]
The OQ-2 is a simple aircraft, powered by a two-cylinder two-cycle piston engine, providing 6 horsepower (4.5 kW) 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 (including licensed contractors) 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. [3]
During the war Radioplane manufactured nearly fifteen thousand drones. The company was bought by Northrop in 1952.

Unmanned aerial vehicles (UAVs) include both autonomous drones and remotely piloted vehicles (RPVs). A UAV is capable of controlled, sustained level flight and is powered by a jet, reciprocating, or electric engine. In the twenty-first century, technology reached a point of sophistication that the UAV is now being given a greatly expanded role in many areas of aviation.

However, the aircraft provided the basis of the GAM-67 Crossbow anti-radar missile.

The Radioplane Company was an American aviation company that produced drone aircraft primarily for use as gunnery targets. During World War II, they produced over 9,400 of their Radioplane OQ-3 model, a propeller-powered monoplane, making it the most-used target aircraft in the US. In the post-World War II era they introduced their Radioplane BTT series, which was produced for years and eventually reached almost 60,000 examples. They also produced several radio control and self-guided missiles, the largest being the GAM-67 Crossbow, which did not enter service. The company was purchased by Northrop Corporation in 1952, and moved to one of Northrop's factories in 1962. One of the last projects carried out at the original Radioplane factory in Van Nuys, California, was the construction of the Gemini Paraglider.
The Radioplane OQ-17 was a target drone produced by the Radioplane Company for the United States Army Air Forces and, as the TD4D/KDR Quail, the United States Navy. Suffering from an unreliable engine, the OQ-17 production run was cut short in favor of the OQ-19.
