1071:. It sank on 23 November 1971 after only 26 hours of operation in Lake Huron, after the cabin was breached by a rock and the engine inexplicably failed, leading the craft to take on water and sink. After this sinking, one of the two San Francisco ACVs was then transferred to the Great Lakes. Another was transferred to the East Coast, where it performed aids to navigation survey/inspection and search-and-rescue operations on Chesapeake Bay, while the third remained in San Francisco Bay. The Chesapeake ACV was found to be particularly valuable for search-and-rescue operations in marshy or shallow waters. In the final Coast Guard evaluation, Commander Thomas Lutton wrote that "The ACV has dramatically and repeatedly demonstrated its capability to effectively perform a wide range of Coast Guard missions." However, the Coast Guard was in the middle of a large upgrade of its other boats and cutters at the time and so did not have the money to acquire ACVs. As such, the two surviving ACVs were transferred to US Army Mobility Equipment Research and Development Center in
824:, the Navy's operations to deny Viet Cong access to resources in the Mekong Delta and prevent North Vietnamese weapons, fighters, and supplies from entering South Vietnam, respectively. The PACVs were deemed unsuitable for Operation Game Warden because of their "mechanical unreliability" and the limitations imposed on them by terrain. As a result, they were removed from the operation and transferred to another Navy unit, CTF 117. They were also found unsuitable for Market Time operations after serving in that operation from 20 September to 17 October 1966, due to their high noise, low visibility, high cost, and limited utility on the high seas or in narrow waterways. In November 1966, the Navy PACVs were used to great effect in Operation Quai Vat (Vietnamese for "Monster", which was what the Viet Cong called the PACVs). In the operation on the
974:-triggered mine on 9 January 1970. Though no one onboard was killed, 14 men were injured and the attack slowed the pace of ACV operations because of Army regulations stipulating that the hovercraft work in pairs to protect each other. When ACV 901 was destroyed by a command-detonated mine on 3 August 1970, killing three, the ACVs were deactivated. The 39th ACV Platoon ceased operations on 31 August 1970 and officially left Vietnam in September, transferring their sole surviving ACV to the Army Transportation Museum in Virginia. Navy PACVs returned to the continental United States that August as well. In total, Navy PACVs saw more than 4,500 hours of operation.

Vietnam in April. There were only three Navy PACVs and three Army ACVs during the whole
Vietnam War. Two of the three ACVs (No. 901 and 902) were Assault Air Cushion Vehicles (AACV), weapons-heavy vessels configured for attack missions, while the other (No. 903) was a Transport Air Cushion Vehicle (TACV) configured for logistics missions. The TACV only carried the twin M60s, forgoing the .50 cal and other weapons to increase space in the cabin for carrying troops. Both AACVs were lost to Viet Cong attacks. Navy PACVs were based out of

The armor was thickest around the engine, transmission, and fuel tanks, providing protection from .50 caliber rounds fired at 200 yards (180 m), while the armor around the crew compartment could only block .30 caliber rounds fired at 100 yards (91 m). To save weight, many crews removed the armor around the crew compartment, and an Army evaluation recommended that it be removed altogether because of it "did not provide any protection to the crew," especially against heavier weapons such as

ACVs were only operational during June 1969. This maintenance requirement, which was made even worse when the vehicles suffered damage, combined with the insufficient firepower to lead an Army evaluation to conclude that "there is no hope of the unit fighting to a satisfactory conclusion in any large engagement." The PACV was also very expensive, costing about $ 1 million each, as much as 13

evaluation found that in the Plain of Reeds, "any mission requiring ground operations can best be accomplished by ACV unts," particularly reconnaissance, light assaults, infantry transport, canal security, cordoning off areas to prevent escape, and patrolling.

For minor repairs to buoys, the ACV shortened what was normally a full day mission by a fully crewed ship to a 2-3 hour one by an ACV with three crew members. The ACV was fast enough that it was able to respond to search-and-rescue calls while servicing buoys, something that was not possible for regular

Another downside of the PACV was the degree of maintenance it required: each hour of operation required 20 hours of maintenance, double the 10-hour average for contemporary military helicopters.

The Navy withdrew the PACVs for overhaul in
January 1967 and redeployed them to Vietnam in early 1968. Also in 1968, the Army began employing its version of the PACV, the ACV. The Army acquired the vehicles and activated their unit, the 39th Cavalry Platoon, in January before deploying them to

Two different designs were made: one for the Navy and one for the Army. The Navy's hovercraft, called Patrol Air

Following their withdrawal in 1970, the Navy PACVs were transferred to the U.S. Coast Guard for evaluation. The Coast Guard used PACVs, which they called Air
Cushion Vehicles (ACVs), through 1975, when they cancelled the ACV program due to budget constraints. Two were stationed at
