Context paragraphs:
Daihatsu-class landing craft: The Daihatsu-class or 14 m landing craft (大発 , abbreviation of 大型発動機艇 which means "large motorized boat") was a type of landing craft used by the Imperial Japanese Army from 1937 to 1945, in the Second Sino-Japanese War and World War II.  It had a bow ramp that was lowered to disembark cargo upon riding up onto a beach.  After reviewing photos of a Daihatsu landing craft, this was adopted by American landing craft designer Andrew Higgins in developing the Landing Craft, Personnel (Large) (LCP(L)) into the Landing Craft, Personnel (Ramped) (LCP(R)) and later the Landing Craft, Vehicle and Personnel (LCVP).  However, the Daihatsu landing craft was more seaworthy than an LCVP due to its hull design.  It was constructed of a metal hull and powered by a diesel engine.

Andrew Higgins: Andrew Jackson Higgins (28 August 1886 – 1 August 1952) was the founder and owner of Higgins Industries, the New Orleans-based manufacturer of "Higgins boats" (LCVPs) during World War II.  The company started out as a small boat-manufacturing business, but later became one of the biggest industries in the world with upwards of eighty thousand workers and government contracts worth nearly three hundred fifty million dollars.  General Dwight Eisenhower is quoted as saying, "Andrew Higgins ... is the man who won the war for us.  ... If Higgins had not designed and built those LCVPs, we never could have landed over an open beach.  The whole strategy of the war would have been different."  Adolf Hitler recognized his heroic war efforts in ship production and bitterly dubbed him the "New Noah."

Higgins Industries: Higgins Industries was the company owned by Andrew Higgins based in New Orleans, Louisiana, United States.  Higgins Industries is most famous for the design and production of the Higgins boat, an amphibious landing craft referred to as LCVP (landing craft, vehicles, personnel), which was used extensively in the Allied forces' D-Day Invasion of Normandy.  Higgins also manufactured PT boats, and produced the first American airborne lifeboat, the model A-1 lifeboat.

LCM (2): The Landing Craft, Mechanized Mark 2 or LCM (2) was a landing craft used for amphibious landings early in the United States' involvement in the Second World War.  Though its primary purpose was to transport light tanks from ships to enemy-held shores, it was also used to carry guns and stores.  The craft was designed by the Navy's Bureau of Construction and Repair and the initial production contract was let to the American Car & Foundry Company.  A total of 147 were built by this company and Higgins Industries.  Because of its light load capacity and the rapid production of the superseding LCM (3), the LCM (2) quickly fell out of use following the Allied invasion of North Africa in 1942.
