USAF / 31st RQS / Full Squadron History / Jolly Green Giant

'VIGILANCE AND HONOUR'

The Squadron was established as the 31st Air Rescue Squadron on October 17, 1952, following its prior designation as A Flight of the 2nd Air Rescue Group at Clark AB, Philippines, which was activated on November 14, 1952. The personnel and aircraft were transferred from A Flight, including the SA-16 Albatross and the HH-19 Chickasaw. Operating under the 2nd Air Rescue Group, the HH-19's were eventually replaced by SH-19 in 1955.

On June 24, 1958, the Squadron was reassigned to the Air Rescue Service and later moved to Naha AB, Okinawa, on September 12, 1960, only to be discontinued six days later, on September 18, 1960. However, the Squadron was quickly reorganized on July 8, 1963, at Clark AB, Philippines, flying the HH-19. It was assigned to the Air Rescue Service (later the Aerospace Rescue and Recovery Service) and attached to the Pacific Air Rescue Centre (which later became the Pacific Aerospace Rescue & Recovery Centre).

In 1964, the HH-19's were replaced by the HH-43, and the squadron also gained the fixed-wing HC-54 Skymaster, which was subsequently replaced by the HC-97 the following year. In 1967, the HC-97 was then replaced by the HC-130.

The Squadron was redesignated as the 31st Aerospace Rescue & Recovery Squadron on January 8, 1966, and was subsequently assigned to the Pacific Aerospace Rescue & Recovery Centre (later known as the 41st Aerospace Rescue & Recovery Wing) on April 1, 1967. They acquired the HH-3E in 1968 and phased out the LBR HH-43's in 1972. From April 1967 to July 1975, the squadron operated the Joint Rescue Coordination Centre for the 13th Air Force. It was then deactivated on July 1, 1975.

It was reactivated on January 8, 1981, once again at Clark AB, Philippines, operating the HH-3 and CH-3, and was assigned to the 41st Rescue & Weather Reconnaissance Wing.

Similar to other Rescue Squadrons, the 31st Squadron actively engaged in Search and Rescue (SAR) operations to assist the local populace. They also provided crucial medical aid to unwell crew members aboard ships, ensuring swift transport to fully equipped hospitals. In June 1982, the Squadron received an urgent call regarding a crewman who had suffered a heart attack aboard the USNS Chauvenet, positioned 350 miles away from Clark near Cuyo Island.

Coordinating with the 33d ARRS, a HC-130 was arranged for refueling due to the extended range. The two-and-a-half-hour flight culminated in a hoist pickup, as the ship's helipad couldn't support the weight of the helicopter. The rescue operation necessitated two air-to-air refuelings with the HC-130.

It was redesignated as the 31^st Special Operations Squadron on 6 Apr 1989.

Operation Firey Vigil

On July 16, 1990, the Island of Luzon was struck by the most severe earthquake in fourteen years, registering a magnitude of 7.7 on the Richter scale. Within hours of the disaster, the squadron's HH-3 aircraft were deployed to deliver aid to the affected local population. The earthquake triggered a landslide, tremors, and temporary steam emissions from a pre-existing geothermal site at Mount Pinatubo. In 1990, the squadron upgraded its aging HH-3 helicopters to MH-53J's.

The eruption reached a height of 80,000 feet, but within 3 days it was over 100,000 high.

Following a year of warning signs preceding an imminent eruption from Mount Pinatubo, the Secretary of Defense announced on June 10, 1991, the initiation of a land evacuation at 0600 local time for all non-essential military personnel and Department of Defense civilian personnel, along with their dependents, from Clark Air Base. Clark Air Base, often regarded as one of the most urbanized military facilities in history and the largest American base overseas, had a permanent population of approximately 15,000 at its peak in 1990. The evacuation was directed towards the U.S. Naval Base Subic Bay, named Operation Fiery Vigil.

The eruption of Mount Pinatubo two days later propelled ash and tephra over 100,000 feet (30,000 meters) into the air. Both Clark Air Base and Subic Bay Naval Station, the two largest U.S. military bases in the Philippines, suffered extensive damage from the volcanic ash. Accumulated ash, reaching nearly a foot in depth due to rain from Typhoon Yunya, caused numerous buildings to collapse under its weight. Flight operations were suspended at both bases for several days, and in some cases, weeks following the eruption. Subsequently, in November, the U.S. relinquished control of both bases to the Philippine authorities, marking the end of 90 years of American history at Clark Air Base.

The squadron had relocated to MCAS Futemna in Okinawa before the closure of Clark Air Base, with the official move taking place on June 29, 1991, just a few weeks after the eruption occurred.

The Squadron was reassigned to the 353rd Special Operations Wing on the April 6, 1989 before moving to Osan AB, South Korea, in July 1992. It was inactivated on August 31 2001.
