LARC-XV

LARC-XV. The LARC-XV was a large amphibious cargo vehicle designed and built in the United States during the mid-20th century. It was part of a family of amphibious vehicles developed for the United States Army and the United States Navy to facilitate logistics over shorelines. The designation stands for Lighter, Amphibious Resupply, Cargo, 15 ton, indicating its payload capacity.

Design and development

The development of the LARC-XV was driven by the logistical requirements identified during World War II and the Korean War, where offloading cargo from ships to shore presented significant challenges. The project was managed by the U.S. Army Transportation Corps with design and manufacturing led by LeTourneau Technologies, a company known for its heavy equipment. The vehicle utilized a welded steel hull and was powered by multiple General Motors diesel engines, driving four large wheels for land travel and propellers for water movement. Its design emphasized reliability and the ability to operate in varied conditions, from the beaches of the Pacific Ocean to the rivers of Southeast Asia. Key testing was conducted at facilities like the Aberdeen Proving Ground and involved coordination with the U.S. Navy's Bureau of Ships.

Operational history

The LARC-XV entered service with the U.S. Army and the U.S. Navy in the late 1950s, seeing extensive use during the Vietnam War. It was instrumental in operations like Operation Market Time, where it helped interdict coastal supply routes, and in supporting the Military Assistance Command, Vietnam by moving supplies from deep-draft vessels to unprepared beaches. The vehicle also participated in numerous joint exercises with allies, including the Australian Army, and was deployed during humanitarian missions, such as disaster relief in the Philippines after Typhoon Karen. Its service continued into the 1970s, with some units remaining active with the U.S. Army Reserve and the Army National Guard before being gradually phased out in favor of newer systems.

Variants

The primary variant was the standard cargo model used by the U.S. Army. A modified version for the U.S. Navy included enhanced communications equipment for use as a command vessel during amphibious assaults. An experimental variant tested by the U.S. Marine Corps featured a reinforced hull and a more powerful engine package from Cummins Engine Company. No major production derivatives followed the LARC-XV, as the larger LARC-LX and smaller LARC-V fulfilled different payload roles within the same vehicle family. Some vehicles were later converted for civilian use as ferries in remote areas of Alaska and Canada.

Operators

The primary operator was the United States Department of Defense, specifically the United States Army and the United States Navy. A small number were used by the Australian Army for trials and training. After retirement from U.S. service, several were acquired by private companies in South America and Southeast Asia for industrial and logistical work. The Army of the Republic of Vietnam also utilized a limited number provided through military aid programs during the Vietnam War.
