Other Equipment and Devices
One of the most useful and interesting FRF vehicles is the LARC-5 (Lighter Amphibious Resupply Cargo), a 4-wheel drive amphibious truck originally built for the Army in the 1960ís. Currently at the FRF there are two in operation. One is set up with a mast and boom to allow it to place instruments, lay underwater cables, support divers, and do many other things. The other Hydro-LARC is currently one of a kind; it has been set up to do bottom surveying, similar to the CRAB, and has also been converted to hydraulic power. The setup includes a GPS unit, a fathometer (sonic depth finder), and software that is able to eliminate waves and tidal fluctuations in the data and give the bottom elevation and location within 2 centimeters accuracy. Both LARCís are capable of carrying up to 4,500 kg (5 tons) and can maneuver at speeds of about 30kph (18mph) on the road and 5 knots in the water. The biggest benefit is that since there is no close inlet, everything that is used in the water must be launched from the shore and the LARC can do just that!

Another important vehicle is the forklift. This is not your ordinary forklift, however; this machine is 4-wheel drive, can carry up to 5,500 kg (6 tons) on it's forks, and has been seen picking up office trailers and trucks! The forklift is used to haul equipment to and from the beach and, on occasion, to rescue vehicles that have become stuck in the sand.
