Kampot-class, Cambodian Sea Truck laid down 1946
This design is a classic example of the Asian-built "Sea Truck": designed to be easily and cheaply manufactured and maintained in all manner of primitive conditions. The Cambodian Navy will employ the craft for training, transport of men and materiel, and virtually every other task under the sun.
