Mariner Patrol Bomber
The Navy shared Martin's interest
in large flying boats, and a full-sized prototype XPBM-1 began tests
in February 1939. PBM-1's began delivery in September 1940.
During 1942 and 1943, PBM-3's
were in the forefront of the battle against
German submarines. Eleven squadrons
were sent out to the Pacific beginning in
late 1943. Between
1950 and 1951 Mariners served in their second
war, once again flying long oversea patrols
with dangerous legs along hostile coastlines.
The last active-service Mariner
was decommissioned by the Coast Guard in
