The V-Jet II was built as a test bed and demonstrator for Williams International. This was the sole example which was first flown in 1997. Eclipse Aviation was founded a year later to continue the concept and developed the design into the Eclipse 500. This aircraft was donated to the Experimental Aircraft Association Museum in 2001

The sole V-Jet II is seen here at Mojave in the year of its first flight. Carrying the logo and titles of "Williams International - General Aviation Propulsion Program" and Burt Rutan's Scaled Composites logo. The design was developed into the Eclipse 500. Retired to the Experimental Aircraft Association Museum at Oshkosh in 2001.

Designed by Scaled Composites as a testbed and demonstrator aircraft for Willams' new FJX-1 turbofan engine. Although the aircraft was not meant for production, the frame drew a lot of interest and it evolved into the Eclipse 500. The prototype flew with a variant of the FJX-22, but they did not give the desired performance and the design was changed to use the PW610F engine. The aircraft (the one and only) was donated to the EAA museum at Oshkosh in 2001.

Small jet engine manufacturer Williams International had Burt Rutan's Scaled Composites design and build the V-Jet II as a test bed and technical demonstrator. First flown in 1997, Eclipse Aviation was founded a year later to continue the concept and developed the design into the Eclipse 500. The sole V-Jet II was donated to the Experimental Aircraft Association Museum in 2001.
