PBM-3D Mariner Prepares to Launch from a Coastal Naval Air Station

A Martin PBM-3D Mariner prepares to launch from a coastal Naval Air Station to patrol for German submarines, probably in late spring 1943. The landing gear had to be manually removed before takeoff and reinstalled before exiting the water. Mariners were one of the most effective of the Navy’s long-range flying boats.
