It is a McDonnell XP67. It was designed in 1941. .Power was provided by two Continental XI-1430-1 engines with GE turbo-superchargers. It had 6 X .50 Cal and four 20mm. It later had 6 37mm canons. The first one assembled without arms was in Dec 1 1943. Fires started in both engines on Dec 8. It flew for the first time on Jan 6 1944. The flight lasted 6 minutes due to problems with the new engines. With a bunch of mods including insulating the turbo it flew three more times before on Feb they overspeeded the engines and burnt out the bearings. Flight test were resumed on March 23. It was tested by USAAF pilots who were somewhat unhappy about its tendency to "Dutch Roll". Some modifications were made including on the dorsal fin and tailplane. On the 6th of September 1944, the prototype succumbed to irreparable fire damage. The contract to build another prototype was cancelled.
