Grumman VC-11A “Gulfstream II” (1969)

Grumman VC-11A  “Gulfstream II” The Coast Guard acquired a single Grumman Gulfstream II in February 1969 as a high speed executive transport for use by the Commandant and the Secretary of Transportation. It was the successor to the highly successful G-159 Gulfstream I (VC-4A). The G1159 design retained much of the VC-4A fuselage and was also fitted with dual nose and main-wheels. New wings with 25 degrees of sweep and swept T-tail were designed. .A turbo-jet, purchased off-the-shelf, it was equipped with an Inertial Navigation System that allowed it to go any place in the world without outside input.  It was based out of Washington National Airport.  The VC-11A flew an average of 600 hours per year and carried an average of 6.5 passengers per flight.

Sikorsky- HH-3F “Pelican” (1967)

Sikorsky- HH-3F   “Pelican” In November 1967 the US Coast Guard procured the first of the HH-3F Pelican Helicopters.   This twin turbine, medium range, amphibious, all weather helicopter extended the Coast Guard offshore search and rescue capabilities.  The HH-3F had a maximum speed of 142 knots with a normal cruise speed of 130 knots and a range of 650 NM. The Coast Guard purchased 40 HH-3F's. The last one was delivered in 1973. The HH-3F was manufactured by Sikorsky Aircraft, Division of United Aircraft Corporation, Stratford, Connecticut. The HH-3F was equipped with a single main rotor, twin engines rated at 1500 SHP each, a fully retractable tricycle landing gear, amphibious capabilities, and a hydraulically operated aft ramp that could be opened in flight, on the ground, or on water. The HH-3F was additionally well suited for marine environmental protection, logistic and reconnaissance support, enforcement of laws and treaties, defense readiness and drug interdiction. . A sliding cargo door is located on the right side of the forward end [...]

1963 – The VC-4A “Gulfstream I” (1963)

1963 - The VC-4A  “Gulfstream I” The Coast Guard acquired a special ordered G-159 Gulfstream 1 executive transport from Grumman Aircraft Corporation on 19 March 1963. Designated VC-4A it was based out of National Airport in Washington, D.C. and used to provide air transportation on a demand basis, to the Secretary of Treasury and members of his staff, the Commandant, U.S. Coast Guard and members of his staff and such other personnel as may be authorized by the Commandant.   The Gulfstream, a commercial aircraft designed for civil use required the implementation of a support system and aircraft maintenance procedures. LCDR John Moseley was assigned this project. Extensive consultation with the Grumman Aircraft Corporation and Atlantic Aviation Incorporated resulted in a maintenance procedure that was unique for its time in that the aircraft was constantly under check but never out of service except for grounding discrepancies and/or major component change requirements. The system proved very successful and was used by NASA for its fleet of G-159 aircraft. Parts support was [...]

Sikorsky HH-52A “Seaguard” (1963)

Sikorsky HH-52A “Seaguard” The Sikorsky HH-52A helicopter was developed from a Sikorsky commercial S-62 amphibious helicopter. The S–62 had features that were desired by the Coast Guard. It floated on an amphibious hull, it was turbine powered, had a large main cabin and it was built utilizing proven components..The automatic stabilization system used on the S-62 was a scaled version of the larger S-61 (SH-3). The rotor system came from the S-55 (HO4S), as did most of the drive system which had already proven to be reliable. The assembly was design limited to 730 shaft horsepower. Small jet engines suitable for helicopters were rare and not available at the time.  Sikorsky solved the problem by using a 1230 SHP General Electric T-58-GE-8B engine and derating it. With the extra 500 HP worth of air capacity on the front end density altitude was not an operational problem. A Coast Guard Evaluation Program confirmed the contractor claims for performance and suitability to fill the mission. A contract for the initial quantity [...]
