The Grumman G-64 Albatross, later designated HU-16 in U.S. military service, is a large, twin-radial-engine amphibious flying boat designed for long-range search and rescue (SAR) missions over both water and land. First flown in 1947, it was developed shortly after World War II to meet the U.S. Navy’s need for a rugged, versatile aircraft capable of open-ocean operations.

The HU-16 Albatross could take off and land on both conventional runways and water, making it a valuable asset for the U.S. Air Force, Navy, Coast Guard, and allied nations. It was used in a variety of roles including SAR, maritime patrol, transport, and even covert operations during the Cold War.
