Čaj Daglas X-3 Stiletto bio je 1950-ih američki eksperimentalni mlazni avion sa vitkim trupom i dugim trakastim nosem, koji je proizvela avionska kompanija Daglas. Njegova primarna misija bila je da istraži dizajnerske karakteristike aviona pogodnog za održive supersonične brzine, koje su uključivale prvu upotrebu titanijuma u velikim komponentama aviona. Daglas je osmislio X-3 sa ciljem maksimalne brzine od približno 2.000 m.p.h, ali je, međutim, bio ozbiljno potcenjen u tu svrhu i nije mogao da premaši ni Mach 1 u nivou leta. Iako je istraživački avion bio razočarenje, dizajneri Lokida su koristili podatke sa X-3 testova za Lokid F-104 Starfighter koji je koristio sličan dizajn krila trapezoidala u uspešnom lovcu Mach 2.

Više informacija:

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.
