Mechanized Landing Craft LCM

The LCM(6) is intended primarily for the transport of cargo and/or personnel from ship-to-ship and ship-to-shore. The craft is a 56-foot twin-screw, welded-steel craft with forward cargo well and bow ramp. The design of the boat permits its transportation aboard larger vessels.

In 1959, the LCM-3 was replaced with the larger 70 ton LCM-8. LCM-8 are manned by a four man crew, Boatswainmate Petty Officer, Enginerman Petty Officer, and a nonrate fireman and seaman. The LCM-8 is constructed of steel and powered by two 12 V-71 diesel engines. The LCM-8 has twin screws and rudders, which can be controlled from the pilothouse. LCM-8 is built of welded steel; it's bottom, however, is semiflat.
