LARC-V

LARC-V. The LARC-V is a wheeled amphibious cargo vehicle designed for logistical operations by the United States Army and the United States Navy. Its primary role was the transport of supplies and personnel from ship to shore, a critical function in amphibious warfare. The vehicle saw extensive service during the Vietnam War and remains a notable example of Cold War military engineering.

Development and design

The LARC-V was developed in the late 1950s to fulfill a requirement for a lighter amphibious resupply vehicle than the larger LARC-XV and LARC-LX. The design and initial production were led by R. G. LeTourneau's company, with later manufacturing undertaken by the Consolidated Diesel Electric Company. Its hull was constructed from welded aluminum alloy, providing buoyancy and corrosion resistance for operations in saltwater environments. The vehicle featured a single, centrally mounted Continental petrol engine that powered all four wheels via a complex transmission system and twin propellers for water propulsion. This design allowed the LARC-V to transition seamlessly between land and water, driving directly from beaches inland to depots or forward units. The cargo area was open-topped, facilitating the rapid loading and unloading of palletized goods, artillery shells, or a complement of troops.

Operational history

The LARC-V entered service with the United States Army Transportation Corps and the United States Navy's Beachmaster units in the early 1960s. Its most significant operational deployment was during the Vietnam War, where it was instrumental in supporting logistics along the coastline and within the Mekong Delta. The vehicles operated from Landing Ship, Tank (LST) vessels and purpose-built landing craft, ferrying everything from ammunition and fuel to food supplies to forces operating in remote areas. They proved vital for operations at ports like Da Nang and Cam Ranh Bay, often working under the threat of enemy fire. Beyond Southeast Asia, LARC-Vs were deployed with US Army units in Europe and were a common sight during training exercises like REFORGER. The United States Marine Corps also utilized them in support of amphibious training at locations such as Camp Lejeune.

Variants

The standard cargo model was the primary variant, but several specialized versions were developed. A workshop variant was created to provide field maintenance support, equipped with tools and parts for repairing other vehicles. An ambulance configuration was also tested, designed to transport casualties from frontline areas to hospital ships offshore. Furthermore, some vehicles were experimentally fitted with light armor kits and machine gun mounts for increased protection in combat zones, though these were not widely adopted. The basic chassis was also evaluated by the United States Coast Guard for potential search and rescue duties, but this did not lead to formal procurement.

Operators

The primary operator was the United States Department of Defense, which fielded the vehicle across its service branches. Following its withdrawal from active U.S. service, many LARC-Vs were transferred to allied nations through programs like the Excess Defense Articles initiative. Foreign military operators included the Philippine Navy, the Argentine Navy, and the Spanish Army. In the civilian sector, surplus LARC-Vs were acquired by private companies for use in maritime construction, oil exploration in regions like the Alaska North Slope, and as unique tourist transports in areas with challenging terrain.

Specifications (LARC-V)

The vehicle had a combat weight of approximately 13 tons and could carry a 5-ton payload. It was 10.7 meters (35 ft) long, 3.3 meters (10.8 ft) wide, and 3.1 meters (10.2 ft) high to the top of the cargo sides. Power was supplied by a single liquid-cooled Continental 6-cylinder petrol engine, producing around 235 horsepower. On land, it could reach speeds up to 40 miles per hour, while its twin propellers enabled a water speed of roughly 8.5 knots. The operational range was approximately 250 miles on roads. It required a crew of two: a driver and a co-driver who could also act as a navigator and loadmaster.
