V Douglas X-3 Stiletto je bilo eksperimentalno letalo iz 50. let 20. Njegova glavna naloga je bila preučiti konstrukcijske značilnosti letala, primernega za vzdržljive nadzvočne hitrosti, ki je vključevala prvo uporabo titana v večjih komponentah zračnega okvirja. Douglas je X-3 zasnoval s ciljem največje hitrosti približno 2.000 m.p.h, vendar je bil v ta namen resno podmožen in pri ravnih letih ni mogel niti presegati Mach 1. Čeprav je bilo raziskovalno letalo razočaranje, so oblikovalci Lockheeda uporabili podatke iz testov X-3 za Lockheed F-104 Starfighter, ki je uporabil podobno trapezoidno zasnovo krila v uspešnem lovu Mach 2.

The Douglas X-3 Stiletto was an experimental jet aircraft designed to test the feasibility of a slender fuselage and a low-aspect ratio wing for supersonic flight. The X-3 was developed by the Douglas Aircraft Company in the late 1940s and early 1950s, and flew for the first time in October 1952. The X-3 had a distinctive appearance, with a long, needle-like nose, a thin, tapered wing, and two Westinghouse J34 turbojet engines mounted in pods under the wing. The X-3 was intended to reach speeds of over Mach 2, but it never achieved this goal due to the inadequate thrust of the engines and the high drag of the wing.
The X-3 did provide valuable data on the effects of high-speed flight on the stability and control of aircraft, as well as on the heating and structural problems caused by aerodynamic friction. The X-3 also influenced the design of later aircraft, such as the Lockheed F-104 Starfighter and the North American XB-70 Valkyrie. The X-3 was retired in 1956 after only 51 flights, and is now on display at the National Museum of the United States Air Force in Dayton, Ohio.
