FS2002 FS2004 Douglas X-3 Stiletto

 The Douglas X-3 Stiletto was a 1950s United States experimental jet aircraft with a slender fuselage and a long tapered nose, manufactured by the Douglas Aircraft Company.
Its primary mission was to investigate the design features of an aircraft suitable for sustained supersonic speeds, which included the first use of titanium in major airframe components.
It was, however, seriously underpowered for its purpose and could not even exceed Mach 1 in level flight.

The Douglas X-3 Stiletto was sleekest of the early experimental aircraft, but its research accomplishments were not those originally planned. The goal of the aircraft was ambitious - it was to take off from the ground under its own power, climb to high altitude, maintain a sustained cruise speed of Mach 2, then land under its own power.
The aircraft was also to test the feasibility of low-aspect ratio wings, and the large-scale use of titanium in aircraft structures.

Construction of a pair of X-3s was approved on 30 June 1949. During development, the X-3's planned Westinghouse J46 engines were unable to meet the thrust, size and weight requirements, so lower-thrust Westinghouse J34 turbojets were substituted, producing only 4,900 pounds of thrust with afterburner rather than the planned 7,000 pounds.
The first aircraft was completed and delivered to Edwards Air Force Base, California, on 11 September 1952. Due to both engine and airframe problems, the partially completed second aircraft was cancelled, and its components were used for spare parts.
