The Martin Mariner was the successor
to the Catalina, and
was somewhat
overshadowed by its famous predecessor. It was an excellent
patrol aircraft
that continued in production after the war, but, like most modern
aircraft,
required much from the pilots
and crew. The Mariner was very
stable, but had
high wing and power loadings. It was capable of carrying a
very heavy weapons
loadout internally and was an excellent antisubmarine
platform.
The concept was first tested with a quarter-scale
single seat prototype, which was followed by a full-size prototype that
first flew on 18 February 1939. This demonstrated the need for the
distinctive dihedral tailplanes. The first production aircraft were
delivered in 1941. Some 25 were given to the British as Lend-Lease in August 1943 but were
returned to the United States six weeks later.
