Mitsubishi B5M
Country: Japan
Type: Attack
Manufacturer: Mitsubishi
Service: 1937 - 1945
First Flight: 1937
Production: 270

The Mitsubishi B5M was an Imperial Japanese Navy (IJN) land-based attack aircraft with an Allied reporting name of Mabel. The IJN designation was Type 97 Number 2 Carrier Attack Bomber. The number two was to distinguish it from the Nakajima B5N, which was called Type 97 Number 1.

The B5M was designed in response to a 1935 specification for a new bomber for use on the IJN aircraft carriers. The machine was to have a crew of three, folding wings for flight deck storage, a speed of not less than 200 mph, a flight endurance of not less than 7 hours, and the ability to carry at least 1,760 pounds of bombs. A total of 270 aircraft were manufactured by Mitsubishi in two variants: 125 B5M and 145 B5M1.

Although designed as a carrier based aircraft, it was relegated to land-based torpedo bomber duties in World War II. These machines ended their careers as trainers, target tugs, and kamikaze bombers.
