During World War II, Kaiser-Fleetwings, a company led by Henry J. Kaiser, entered the aviation industry. They presented various fighter designs to the U.S. Army Air Forces (USAAF) and the U.S. Navy (USN). Their most notable project was the XBTK-1 in 1945, which had five prototypes built and tested. In February 1944, they tried to interest the U.S. Navy in their Type 47 strike/dive bomber for aircraft carriers, which aimed to combine British-American Packard "Merlin" engines with Westinghouse turbojets for enhanced power. The Type 47 featured a streamlined design with a single-seat cockpit, innovative transparent canopy, and armor for cockpit and engine protection.
The Type 47's sleek airframe had main wings located low on the fuselage, each housing an inline piston engine and a Westinghouse turbojet in nacelles. It included a three-wheeled undercarriage for ground and deck operations, along with safety gear and flaps suitable for Navy use. The design prioritized survivability with cockpit and engine armor and self-sealing fuel tanks, making it well-suited for its low-level attack role.
Kaiser-Fleetwings' foray into aviation during World War II led to the development of the Type 47, a unique strike/dive bomber concept that combined different propulsion technologies to deliver power and versatility, all while focusing on pilot safety and aircraft survivability.
