Latest update of the helicopter that had disappeared from the radar on 25/06/2016 mentioned that the searchers allegedly smelt gasoline. But the rescue teams had to retreat from a monsoon storm before they could get any closer. The search would begin again tomorrow.

UH-1H “Huey” Helicopter

Vietnam UH-1H “Huey” Helicopter

From 1965 to 1973, the Bell UH-1, officially named “Iroquois” was the most common utility helicopter used in Vietnam. The “Huey” nickname stuck thanks to her early “HU-1” designation (it was later redesignated to UH-1 with the normalization of 1962). This particular helicopter is a “Slick”, used for troop carrying. It is not fitted with external weapons to save weight and is only armed with the M60s used by the door gunners. These aircraft operated in the hostile environment of Vietnam for almost a decade.

This Huey served in the 25th Infantry Division in Vietnam, performing troop insertions and extractions, medical evacuations, helicopter crew recoveries, smoke, sniffer psyops, and firefly missions. Based at Cu Chi, it survived multiple small arms attacks and one RPG strike. It was returned to service in 2011 to operate as a “Thank You” to Vietnam War Veterans and has completed over 180 missions since then.

Many Vietnam Veterans describe the UH-1 “Huey” helicopter as the “sound of our war”. Vietnam Helicopter Pilots Association records show that 7,013 Hueys survived in the Vietnam War, totaling 7,531,955 flight hours. Over 90,000 patients were airlifted (over half of them Americans). The average time between field wound to hospitalization was less than one hour. During the Korean and World War II wars this time was measured primarily in days, not hours. The utilization of helicopters dramatically increased warfare survival rates.


Primary Armament:

Typical armament included two M-60D machine guns on fixed door mounts manned by the Crew Chief on the left and a Door Gunner on the right. The M-60D is a 7.62mm NATO caliber weapon with a cyclic rate of fire of 600 to 700 rounds per minute. The large cans below the M-60’s held roughly 2,000 rounds of linked 7.62mm ammunition and were a typical field modification replacing the authorized can which held 500 rounds.

Secondary Armament:

Each Crew Chief and Door Gunner also carried a secondary weapon, usually an M-16 rifle but sometimes more exotic types. Because pilots were not issued M-16’s, they often carried other unauthorized weapons slung over their armored seats for personal protection. Crew Chiefs and Door Gunners always carried colored smoke grenades, often as you see them here on the seat posts. These were used to mark targets for the Gunships when receiving hostile fire or to mark landing zones (LZ’s).

Body Armor

All aircrew were issued body armor, jokingly referred to as “chicken plates”. If a Crew Chief or Door Gunner chose not to wear it, the chicken plate was often stowed under his seat for protection from enemy weapons fire from below.
