Hobby Master 1-72
HH1012 HA(L)-3 "Seawolves" US Navy, Task Force, 1967

There were 766 UH-1C helicopters built in several equipment modified variants. One was the “Frog” equipped with side-mounted XM-158 twin rocket pods each holding seven 2.75 inch rockets. The "M-5" fitted the gunship with a nose turret mounting an M-75 40 mm automatic anti-personnel grenade launcher that held 300 anti-personnel grenades. The crews referred to these as “Chunkers” because of the sound when the grenades were fired. The infamous “Shark” gunships were created in 1966 when permission was granted to use the fearsome looking “Tiger Mouth” on the front of the Hueys.

HA(L)-3 “Seawolves” Helicopter Attack Squadron (Light) three was formed in 1966 to support Naval Special Warfare operations and Mobile Riverine Forces in Vietnam. The unit was first formed using 8 volunteer pilots and was formally commissioned in April 1967. The Seawolves were used for SAR, recon, MEDEVAC and insertion and extraction of Navy Seal teams. The Seawolves were decommissioned in January 1972 but not before flying 120,000 combat sorties with 44 being killed and 200 wounded.
