Mission Statement

The problemLCM-8 “Mike Boat” LCAC- Landing Craft Air Cushion

LCM-1E

The solution

LENGTH : 13 m WIDTH : 8 m HEIGHT : 5 mWEIGHT : 38 tons

Buoyant Tracks on the UHAC

Mixed Load

UHAC vs LCACUHAC LCAC

Deck area (square feet) 2,500 1,800Payload (tons) 190 65

Range (nautical miles) 200 86Speed (knots) 20 40

Unlike the LCAC, the UHAC can continue moving while onshore across mud flats, tidal marsh areas, and even over sea walls of up to 10 feet in height.

Conclusions

The UHAC• prototype is a ship-to-shore connector and is half the size of

the intended machine• could work side by side with the LCAC• could save a lot of time and fuel
