USACE LARC-5

The LARC-5 (Lighter Amphibious Resupply Cargo) is an Army amphibious vehicle that is used to deploy instruments, support diving activities, collect data, and tow a variety of sensor and survey "sleds". The LARC-5 survey vehicle is 10.6 m (35 ft) long, 3 m (10.2 ft) wide and 3.3 m (11 ft) tall. It has a maximum land speed of 40 kph (25 mph) and approximately 11 kph in water, with a typical survey speed of 7 kph.
