Title: Martin P4M Mercator

The Martin P4M was designed as a maritime reconnaissance aircraft intended to replace the PB4Y-2, and first flew in 1946. However the aircraft lost out to the  Lockheed P2V Neptune, but 19 were ordered as high-speed minelayers. After brief service in this role, most aircraft were converted to electronic reconnaissance aircraft. They continued in this very secret role until their retirment in 1960.
