The twin-engine combat platform proved popular with the forces of the Japanese Empire during World War 2 (1939-1945) - they offered capable bomb loads, strong performance, and the operational ranges needed to cover the vast reaches of the Pacific. One mid-war twin-engine bomber development became the Yokosuka P1Y "Ginga" (meaning "Galaxy") which was developed for the Imperial Japanese Navy (IJN) but intended for service from established land bases. Production reached 1,102 units before war's end. The Allies codenamed the bomber "Frances".
The Yokosuka Naval Air Technical Arsenal pushed for a new modern combining the operational range, firepower, and performance of the best platforms then available to the IJN. In additional to conventional level bombing, it was thought to include a capability for dive bombing and torpedo bombing to make for a more multi-faceted battlefield performer. Engineers elected for a conventional monoplane design form incorporating the two engines at each wing leading edge. The nose section of the aircraft was glazed for good vision out-of-the-cockpit and for bombing. The wing mainplanes were mid-mounted appendages and the tail given a traditional single-rudder form. A "tail-dragger" undercarriage was used. The operating crew would number three. Dimensions included a length of 49 feet, a wingspan of 65.5 feet and a height of 14 feet. Empty weight was 16,000lb against a Maximum Take-Off Weight (MTOW) of 29,765lb.
The engines were 2 x Nakajima NK9C "Homare 12" series 18-cylinder radial piston engines of 1,825 horsepower each. Performance specifications included a maximum speed of 340 miles per hour, a cruising speed of 230 miles per hour, a range out to 3,340 miles, and a service ceiling up to 30,840 feet.
Beyond the internal bombload of 2,205lb (or 1 x 1,800lb torpedo), the aircraft typically carried defensive armament in the form of 1 x 20mm Type 99 cannon in the nose and 1 x 13mm Type 2 heavy machine gun facing aft on a trainable mounting).
