Bell XF-83
     The XF-83, like the XF-81 was an attempt to solve the limited
 range problem of early jets fighters. The XF-83 was essentially an
 improved version of the Bell P-59 modified for two J-33 turbojets
 and large internal fuel tanks holding up to 1,150 gallons. The first
 of two XF-83s ordered (S/N 44-84990 & 44-84991) first flew on 25
 February 1945.
     The XF-83 featured a pressurized cockpit because of expected
 operating altitudes above 40,000 feet. The engines were mounted
 close to the aircraft centerline for increased safety. If one engine
 failed, the other wouldn't cause serious control problems due to
 asymmetrical thrust.
     Testing showed the aircraft was too heavy and didn't offer any
 significant improvement over existing fighters and thus never
 entered production.
