Almost everyone who has ever watched a war movie has seen LCMs in action. With their huge bow ramps that drop to allow men and equipment they carry to "hit the beach" in an amphibious assault, they are the link between the beach and the large transport ships that sit offshore. Called boats instead of ships because of their size and affectionately referred to as "Mike" boats by those who love them, the Landing Craft, Mechanized (LCM) play a vital role in the Navy's amphibious assault mission.

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, known to the Marines at the Mike boat. LCM-8 are manned by a four man crew, Boatswainmate Petty LCM 502Officer, 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. Capable of carrying 60 tons of cargo, the LCM is a highly-versatile workhorse for the amphibious force commander.

The LCM-8 Mod 2 will function as a command and control (C2), personnel transfer and a light salvage/firefighting vessel. The Army will modify existing LCM-8s for this purpose. The total requirement for the Mod 2 is 14 (4 Prepo, 5 AC, 5 RC). The LCM-8 Mod 2 will perform many key support functions in conditions through sea state 3. The LCM-8's proven record of performance provides a solid platform for this modification. As a C2 platform, the Mod 2 will provide the critical link between ship and shore operation centers. It will transport Army stevedores from shore to ship/ship to shore in a protected environment. It will also be used as a MEDEVAC vessel, diver support platform, limited firefighting and light salvage boat. The Mod 2 will function in shallow inlets, rivers and surf zones. It will retain its ability to land on an unimproved beach.

The LCM-8 transports cargo, troops, and vehicles from ship to shore or in retrograde movements. It is also used in lighter and utility work in harbors. The LCM-8 is designed for use in rough or exposed waters and can be operated through breakers and grounded on the beach. The bow ramp allows RORO operations with wheeled and tracked vehicles. Its small size allows for use in confined areas. The LCM-8 can be transported by LSVs, LCU 2000s, LSTs, commercial bulk carriers, and heavy lift ships.
