Martin JRM Mars Heavy Transport and Firefighting Flying-Boat Family

The Martin JRM Mars is a four-engine heavy flying-boat family whose prototype first flew in 1942. Reworked from a maritime patrol concept into a long-range U.S. Navy transport, the production aircraft later gained a second career in British Columbia as high-capacity water bombers, using their boat hulls and large internal tanks to scoop and drop water on thousands of wildfires.
