Landing Craft Infantry
Landing Craft Infantry were designed to deliver soldiers and marines quickly during an
amphibious assault on enemy territory.  LCIs didn't share the limelight like the more
glamorous aircraft carriers, battleships and destroyers. In fact they earned the name
"Waterbug Navy," when an admiral looked down from his battleship and watched the LCI's
down below scurrying back and forth, and commented that they looked like a bunch of
waterbugs. Landing craft were 158 feet long and 23 feet 3 inches wide at the middle. The
hull or skin was made of 1/4 inch steel plate. The propulsion of the ship was two sets of
quad General Motors 6 cylinder diesel engines generating 1600 HP ; 8 engines total.

LCI's used at Marinduque: 634, 639, 688, 702, 703, 712, 750, 1001, 1006, 1025, 1071,

Landing Ship Medium
Landing Ship Medium were amphibious assault ships of the United States Navy in the World
War II. Of comparable size to Landing Ship, Tank and the Landing Craft, Infantry, there were
558 LSM (Landing Ship, Medium) made for the USN between 1944 and 1945. The majority
of vessels built on this versatile frame were regular transports however there were several
dozen that were converted during construction for specialized roles.  
General Measurements: Length 203.5 feet  Beam 34.5 feet
Speed 13.3 knots Endurance 4,900 miles (12 kts)
Weights: Displacement (Light) 520 tons Displacement (Loaded) 900 tons
Payload (Beaching) 150 tons
Crew (Typical) Officers 4  Enlisted 54
Standard LSM Armament: 1 - 40mm Cannon Twin Mount  4 - 20mm Cannons

LSMs used at Marinduque: 315
LSM-315
The ship was built by the Pullman Standard Car Manufacturing Company in Chicago, Illinois
and was commissioned into the United States Navy (USN) as USS LSM-315 on 13 July
1944. She was assigned to the Pacific Theater of Operations and saw action during the
liberation of the Philippines during 1944 and 1945. Following the war she was
decommissioned on 14 June 1946 and laid up in the Pacific Reserve Fleet.
PT boats were a variety of torpedo-armed fast attack craft used by the United States Navy in
World War II to attack larger surface ships. "PT" is the US hull classification symbol for
"Patrol Torpedo". The PT boat squadrons were nicknamed "the mosquito fleet". The
Japanese called them "Devil Boats".  The PT boats used in World War II were built using the
planing-type hull form developed for racing boats. They were much smaller (30–75 tons) and
faster (35–40 knots). They were designed to strike at larger warships with torpedoes, using
relatively high speed to get close, and small size to avoid being spotted and hit by gunfire.
They were much less expensive than large warships. PT boats were much faster, smaller,
and cheaper than conventional (displacement hull) vessels.
