Helicopter Combat Support Squadron Seven


Helicopter Combat Support Squadron Seven was a helicopter squadron of the United States Navy established on 1 September 1967 and disestablished on 30 June 1975.

History

was reorganized to create several additional helicopter squadrons. The existing HC-1 Detachments based at NAS Atsugi and NAAF Ream Field, Naval Outlying Landing Field Imperial Beach were redesignated Helicopter Combat Support Squadron SEVEN. Established with sixteen officers and seventy-five enlisted men on 1 September 1967. Upon establishment, HC-7 was tasked with multiple missions including Logistics, Vertical Replenishment, Seventh Fleet Flagship, Aerial Mine Countermeasure, Oceanographic, home station search and rescue and combat search and rescue.
Volunteer crewmen attended Combat Aircrewman Rescue School which included training in “JEST”, SERE, combat swim school, aerial gunnery/weapons, medical, hand-to-hand combat, 10’-10 mph helo rescue swimmer deployment. HC-7 owed its success to the establishment of the training instructors of “Paramedic Rescue Team ONE”, NAS Cubi Point, Republic of Philippines.
During Operation Rolling Thunder the Navy maintained units in the Gulf of Tonkin to retrieve downed fliers from the sea and from North Vietnam and Laos. Normally, two destroyers were deployed to the forward, North SAR Station and another two to the South SAR Station. To carry out rescues in North Vietnam's lethal environment, one UH-2 Seasprite helicopter equipped with self-sealing fuel tanks, machine guns, and armor was placed on board a ship at each station. Another four similarly armed and armored SH-3A Sea Kings were based on one of the Yankee Station carriers.
As the Vietnam War intensified the squadron deployed 16 separate detachments, constantly on the move, branded with the nickname “The Orphans of the Seventh Fleet”. HC-7 helicopters Cross-decked to a new ship on an average of 14 day to a new home as the host ships departed the Gulf of Tonkin. HC-7 was continuously stationed in the Gulf of Tonkin. HC-7 crews rescued 150 persons, 130 of which were within the Vietnam Combat zone. Two pilots were rescue twice. Five successful rescues took place deep within North Vietnam, many rescues occurred along the coast within range of heavy enemy artillery. One of its members, Lieutenant Clyde Everett Lassen received the Medal of Honor. In July 1971 HC-7 was awarded Presidential Unit Citation for the period 1 September 1967 to 30 April 1969 for Extraordinary Heroism.

Commanding officers

HC-7's insignia has a central focal point Cerberus who acclaimed as one of the most feared creatures in Greek and Roman mythology. The three heads attached to a single body symbolize the three basic missions of the squadron: rescue, vertical replenishment and utility. The gold circle surrounding the insignia represents a halo, hence the downed aviators reference to the rescue helicopter an “angel”. The insignia was approved in August 1968.

Aircraft

92 aircraft in total
HC-7 helicopter armament included M16 rifles, M79 grenade launchers, M60 machine guns. In 1970 Big Mother H-3s were modified installing a GAU-2B/A minigun upon armor plated mount in right rear aft cargo door. The HH-2Cs arrived having a chin mounted minigun turret system, no guns were ever received. With essential CSAR equipment installed, to remain below the 12,500-pound max., the turret system was removed. Fuel and CSAR equipment had priority over the minigun. M60 machine guns were mounted in the cargo doors. The H-3s were tested with minigun pods mounded exterior aft, which proved to be too heavy for the existing climate of the war zone.
