The Douglas F5D Skylancer is a development of the F4D Skyray jet fighter for the United States Navy. Starting out as the F4D-2N, an all-weather version of the Skyray, the design was soon modified to take full advantage of the extra thrust of the Pratt & Whitney J57 eventually fitted to the Skyray instead of the Westinghouse J40 originally planned.
