LVTE1 was the engineer version of the LVTP5. A large, toothed, V-shaped excavator blade was mounted on the front of the vehicle, and it could clear a path through a minefield that was 16" (41cm) deep and 12 feet (3.7m) wide. Plastic foam-filled buoyancy tanks were fitted to the rear of the blade to help the LVTE1 keep the right attitude while afloat, and explosive bolts could be issued during combat to jettison the blade should it become damaged or otherwise a hindrance. A rocket-propelled line charge was carried in either side of the cargo compartment, and these were elevated hydraulically. The used line charge pallet was discarded after firing. The familiar machine gun cupola was installed between the commander and driver.
Late-production LVTE1s were powered by the Continental AVI-1790-8 12-cylinder, fuel injected gasoline engine found on the 90mm gun tank M48A2. These vehicles did not feature recessed radiator compartments on the rear sides, and also lacked the armored covers for the engine air intake and exhaust on the rear deck.
