Naval Fighters Number Forty-Eight : Kaiser Fleetwings XBTK-1;

The Kaiser Fleetwings XBTK-1 was initially designed to meet a 1943 Navy requirement for a "single-seat carrier based high performance dive bomber." As was the normal war-time practice, design studies were requested from companies without a major production model and, with the Navy's acceptance of the proposal from the Fleetwings company, the design was designated XBK-1.
