The Martin Mars flying boat was originally built as an experimental patrol bomber with the designation XPB2M-1. It first flew in July 1942. This was the twin ruddered tail version of the Mars. It was modified as a cargo transport flying boat and redesignated as XPB2M-1R. The JRM Mars was the production development of the XPB2M1-R. 20 were ordered the first of which flew in the summer of 1945, The fourth JRM-1 in summer 1946 and the fifth JRM-2 in the fall of 1947.
First installed with (4) Wright R-3350 (2100 hp) Duplex Cyclone radials. The fifth Martin JRM Mars was installed with (4) Pratt & Whitney R-4630 (3000 HP) Wasp Major radials but was later retrofitted with the Wright R3350-24WA radials (2500 HP) to be compatible with the fleet.
The two Mars phtographed here still fly today.

If you save the Greenstone Mountain Fire Photo (right) and then zoom in on the lower right corner, you will see a speck. That is not dirt on the negative. It is the Martin Mars. It gives you a perspective on how large a battle these crews have.
