Grumman HU-16 Albatross model. Inspired by the performance of the Grumman Goose during WWII, the U.S. Navy solicited Grumman to design a significantly larger amphibian with longer range. In 1944, Grumman submitted and won approval of its design G-64, to be named "Albatross," with accommodation for a crew of four, and a cabin capacity of 10 passengers, stretchers, or 5,000 pounds of cargo, as circumstances dictated. In addition, there were pylons under the wing and outboard of the engines which made it possible to carry weapons or drop tanks for increased range. In addition, fuel could be carried in the fixed underwing floats.
