That core was augmented by vessels fleeing the Japanese advance, particularly twenty-one Dutch vessels later known as the "KPM vessels" after the Dutch shipping line's name, Koninklijke Paketvaart-Maatschappij. As of 28 April 1942 the Army fleet had grown to twenty-eight ships and by 24 January 1945 that fleet of large ships exceeded ninety with a peak of ninety-eight by 1 August 1945. That number did not count a much larger fleet of small vessels, ranging from landing craft, barges and other floating equipment to seagoing vessels under 1,000 tons, including the Small Ships Section of requisitioned and locally constructed (2,712 craft) vessels manned largely by Australian civilian employees, 1,719 as of June 1945, of the U.S. Army, and many such vessels and floating equipment delivered from the United States. The permanent fleet of SWPA almost had as many vessels as the Army’s general fleet during some periods, though those vessels were often small, obsolete, in poor condition and under unorthodox management in comparison.
