JRF-5 Goose

The Grumman JRF‑5 Goose is a twin‑engine amphibious aircraft that entered service in the early 1950s as an evolution of the legendary Grumman JRF‑4. Designed for both land and water operation, the Goose featured a rugged all‑metal airframe, a high‑mounted wing with retractable floats, and two Pratt & Whitney R‑985 Wasp Junior radial engines delivering 450 horsepower each. Its spacious cabin could accommodate up to eight passengers or cargo, while the sturdy landing gear and hull allowed operations from unprepared runways, lakes, and coastal waters. First delivered to the U.S. Navy for transport and liaison duties, the JRF‑5 quickly found buyers among civilian airlines, remote mining companies, and government agencies that required reliable access to isolated regions. The aircraft’s versatility, short‑takeoff capability, and corrosion‑resistant construction made it a workhorse in Arctic and tropical environments alike. Though production ceased in 1955 after only 100 units, the Goose’s legacy endures; many examples remain airworthy, serving as a testament to Grumman’s innovative amphibious design and its lasting impact on multi‑role aviation. Today, fly‑ins and historic fleets showcase the Goose, highlighting its enduring charm and engineering excellence.
