Grumman HU-16 Albatross

I was in Air Explorers in Lajes AFB, Azores...we were supported by the Naval Air
Facility there and they occassionally took us up in their HU-16.

The Grumman HU-16 Albatross is a large twin–radial engine amphibious flying boat
that was used by the United States Air Force (USAF), the U.S. Navy (USN) and the
U.S. Coast Guard (USCG), primarily as a search and rescue aircraft. Originally
designated as the SA-16 for the USAF and the JR2F-1 and UF-1 for the USN and
USCG, it was redesignated as the HU-16 in 1962.

Design and development

An improvement of the design of the Grumman Mallard, the Albatross was developed
to land in open ocean situations to accomplish rescues. Its deep-V hull
cross-section and keel length enable it to land in the open sea. The Albatross
was designed for optimal 4-foot (1.2 m) seas, and could land in more severe
conditions, but required JATO (jet-assisted take off, or simply booster rockets)
for takeoff in 8–10-foot (2.4–3.0 m) seas or greater.
Operational history[edit]

The majority of Albatrosses were used by the U.S. Air Force, primarily in the
search and rescue mission role (SAR), and initially designated as SA-16. The
USAF used the SA-16 extensively in Korea for combat rescue, where it gained a
reputation as a rugged and seaworthy craft. Later, the redesignated HU-16B
(long-wing variant) Albatross was used by the U.S. Air Force's Aerospace Rescue
and Recovery Service and saw extensive combat service during the Vietnam War. In
addition a small number of Air National Guard air commando groups were equipped
with HU-16s for covert infiltration and extraction of special forces from 1956
to 1971.[2] Other examples of the HU-16 made their way into Air Force Reserve
air rescue units prior to its retirement from USAF service.

The U.S. Navy also employed the HU-16C/D Albatross as a search and rescue (SAR)
aircraft from coastal naval air stations, both stateside and overseas. It was
also employed as an operational support aircraft worldwide and for missions from
the former NAS Agana, Guam during the Vietnam War. Goodwill flights were also
common to the surrounding Trust Territory of the Pacific Islands in the early
1970s. Open water landings and water takeoff training using JATO was also
conducted frequently by U.S. Navy HU-16s from locations such as NAS Agana, Guam;
Naval Station Guantanamo Bay, Cuba; NAS Barbers Point, Hawaii; NAS North Island,
California, NAS Key West, Florida; NAS Jacksonville, Florida and NAS Pensacola,
Florida, among other locations.

The HU-16 was also operated by the U.S. Coast Guard as both a coastal and
long-range open ocean SAR aircraft for many years until it was supplanted by the
HU-25 Guardian and HC-130 Hercules.

The final USAF HU-16 flight was the delivery of AF Serial No. 51-5282 to the
National Museum of the United States Air Force at Wright-Patterson AFB, Ohio in
July 1973 after setting an altitude record of 32,883 ft earlier in the month.

The final US Navy HU-16 flight was made 13 August 1976 when an Albatross was
delivered to the National Museum of Naval Aviation at NAS Pensacola, Florida.[3]
