20th Observation Squadron emblem (approved 31 October 1942[3]
Military unit
The 20th Special Operations Squadron is part of the
27th Special Operations Wing at
Cannon Air Force Base, New Mexico. It operates
Bell Boeing CV-22 Ospreys on special operations missions. It traces its history back to the activation of the 20th Observation Squadron (Light) at Savannah, Georgia, in March 1942.
The squadron conducts day or night low-level penetration into hostile enemy territory, to accomplish
clandestine infiltration and exfiltration, aerial gunnery support and resupply of special operations forces throughout the world.[4]
History
World War II
The 20th Tactical Reconnaissance Squadron trained for aerial
reconnaissance from March 1942 to December 1943, then went on to fly combat missions in the
China-Burma-India Theater from 31 January 1944 to 5 May 1945.[1]
Light transportation
The 20th Helicopter Squadron was activated in 1956 to perform traditional helicopter missions with
Piasecki H-21 Workhorses for the
Tactical Air Command. It was inactivated in 1960.
In 1967, the 20th was joined by the
Bell UH-1 Huey helicopters formerly assigned to Project Lucky Tiger and the Hueys became known as the Green Hornets. The "Green Hornets" supported Special Operations in South Vietnam and Cambodia. In August 1969 the Pony Express CH-3E's were transferred to the
21st Special Operations Squadron at
Nakhon Phanom Royal Thai Air Force Base, and the Pony Express ceased to exist. The heritage of the 20th was carried on by the 20th UH-1's Green Hornets.
Aircraft and crew losses
31 March 1967, MAJ Robert L Baldwin, piloting UH-1F Tail No 65-07932 was shot and killed in Laos.[5]
27 November 1968, UH-1F Tail No 65-07942 operating from
Ban Me Thuot East Airfield was shot down near Phu Nhai Village, Rotanokiri Province, Cambodia, 16 km west of Duc Lo, South Vietnam while trying to infiltrate a Special Forces team. The Crew Chief, SSgt Gene P. Stuifbergen[6] and 4 of the Special Forces team were trapped in the burning wreckage and were all listed as KIA-BNR.
3 January 1969, UH-1F Tail No 63-13164 operating from Ban Me Thuot was making its second attempt to extract a Special Forces patrol in Cambodia. As they came to a hover above the trees, enemy fire struck the fuel cells setting the aircraft on fire. They were able to accelerate the aircraft and attempted a landing in a small jungle clearing, but the engine failed just short of the clearing and the helicopter crashed into the trees. The crew chief, Sgt Ronald Zenga, was pinned under the aircraft and died in the ensuing fire.[7]
17 January 1969, Pony Express 20 CH-3C Tail No 62-12582 operating from
Udorn Royal Thai Air Force Base crashed while on a
TACAN service mission to Lima Site 36 in Laos. 3 of the crew were killed.[8][9][10]
26 March 1969, UH-1F Tail No 63-13158 operating from Ban Me Thuot crashed and burned near
Dục Mỹ, north of
Nha Trang, South Vietnam. The aircraft experienced severe vibration and auto-rotation was initiated, but during the descent the main rotor severed the tail boom. All 5 crewmen were killed.[11][12][13][14][15]
13 April 1969, Capt James O. Lynch, piloting UH-1F, AF Ser. No. 65-07937, operating from Ban Me Thuot was shot and killed while extracting a reconnaissance team near
Pleiku, South Vietnam.[16]
14 March 1970, UH-1P, AF Ser. No. 64-15491, operating from Ban Me Thuot was shot down while supporting a
LRRP mission near
Duc Lap, South Vietnam. The pilot, Capt Dana A. Dilley, was killed in the crash.[17]R.A. the Rugged Man tells the story of his father's (Sgt
John A. Thorburn) part in this crash in the song "
Uncommon Valor: A Vietnam Story".
19 March 1970, UH-1P, AF Ser. No. 65-07944, operating from Ban Me Thuot was shot down near Darlac, South Vietnam. The pilot, copilot and a gunner were killed in the crash.[18][19][20]
25 September 1970, UH-1P, AF Ser. No. 64-15484, operating from Ban Me Thuot hit trees while turning to avoid a mid-air collision with a
VNAFCH-34 near Quang Duc, South Vietnam. The aircraft subsequently caught fire and the pilot and a gunner were killed in the crash.[21][22]
4 December 1971, a UH-1N operating from Ban Me Thuot came under fire near
Saigon. The gunner, Sgt Thomas E. Fike, was killed.[23]
The Green Hornets continued to perform unconventional warfare missions for seven years, until inactivation in 1972.

UH-1P Tail No 64-15493, probably used by 20th SOS, at Hurlburt Field
1976 Reactivation
Upon reactivation in 1976 at
Hurlburt Field, the unit mission remained unconventional warfare and special operations using UH-1N gunships and CH-3Es. The
HH-53H Pave Low replaced the CH-3E in 1980, providing a long range, heavier lift helicopter capability. "The Air Force's newly operational fleet of nine HH-53H Pave Low CSAR helicopters was abruptly transferred to the special operations forces in response to the failed Iranian hostage rescue attempt and the lack of dedicated long-range vertical lift platforms."[24][25] The crews used the Pave Low
avionics to arrive over target on time and undetected, where they performed terminal operations wearing
night vision goggles.[4]
In 1983, the UH-1Ns began two years of support as part of then Vice President
George Bush's South Florida Drug Enforcement Task Force, participating in Operation Bahamas, Antilles and Turks (BAT). The Op BAT Hueys flew hundreds of over-water missions from the
Bahamas before transferring to
Homestead Air Force Base, Florida in 1985.[4]
In 1986, the 20th flew the specially equipped and highly capable
Sikorsky MH-53 Pave Low and started flying the upgraded MH-53J Pave Low III in 1988.[4]
In December 1989, members of the 20 SOS were mobilized as part of a joint task force for
Operation Just Cause, in
Panama.[4]
Squadron personnel deployed in support of Operation Restore Democracy in Haiti, providing support to a
National Command Authority resolution. Members of the 20th, participating in operations in Bosnia and Herzegovina, went into harm's way in attempting a rescue of two downed French crewmen, receiving two
Purple Heart Medals and the
Cheney Award.[4]
20 SOS crews were also involved in the search and rescue operations resulting from the
CT-43 crash in which Commerce Secretary
Ron Brown and his party died. These same crews deployed shortly thereafter to support the
American Embassy evacuations in
Monrovia, Liberia – airlifting more than 2,000 evacuees to safety. The squadron deployed crews and aircraft to Southwest Asia in support of
United States Central Command and Operation Desert Thunder in February 1998. The Pave Low gave the theater commander a night, all-weather personnel recovery capability, unparalleled in the U.S. inventory.[4]
To date, the Green Hornets have flown direct assaults on numerous high-profile targets and effected the rescue and exfiltration of hundreds of US and allied soldiers. Included among these actions are the daylight
medevac of 32 injured soldiers in the midst of a battle and the rescue of a downed aircrew deep in hostile territory, which earned the squadron its second MacKay Trophy.[4]
