The Martin Mars Water Bomber is world's largest propeller driven water bomber and the largest seaplane ever to enter production.

The U.S. Navy contracted for the development of large transport aircraft in 1935. In answer the manufacturer enlarged their PBM Mariner patrol bomber to produce the JRM-1 Mars series of aircraft. This went on to become the Mars Water Bomber.

After successful testing of the prototype, the U.S. Navy ordered 20 aircraft. The first was delivered in June 1945, but with the end of the war the Navy cut their order to only five additional aircraft for a total of six in all, with the last one delivered in 1947.

The production Mars aircraft entered service transporting cargo from the U.S. to Hawaii and other Pacific Islands. Through the years, four of the aircraft were lost in various incidents. One of the aircraft set a load weight record of 62,282 lbs. in 1948 and another record for carrying 269 people aloft in 1949.

The Martin Mars Water Bomber entered service in 1963. Two aircraft were converted to water bombers. They are operated by Flying Tankers, Inc. and are based at Sproat Lake near Port Alberni, British Columbia.

One of the two aircraft, the Hawaiian Mars, had recently been temporarily based at Lake Elsinore in Southern California. It was employed to fight Southern California blazes.
