The current naval plan for Cambodia appears as follows:
---- Four 160t "sea trucks", named Kampot, Ratanakiri, Ta Khmao, and Serei Saophoan, shall be built in the local drydock at a rate of one per quarter. These vessels are wooden hulled and shall serve as unarmed (or meagerly armed) coastal transports and tenders.
---- Four 160t torpedo boats of the La Combattante II class shall be ordered from France, with two boats ordered in Q3/46, and two more in Q4/46. These boats shall be named Battambang, Koh Kong, Preah Sihanouk, and Kampong Speu. Delivery shall likely occur sometime in 1947. These boats shall be used for coastal patrol and coastal defense.
---- Sixteen fast riverine patrol craft, of ten tons each, will be delivered from Q1 onward at a rate of four per quarter.
---- 560 tons remain unspoken-for at present. Among the ideas I have in mind are a set of very small coastal or harbour minesweepers, a port tug, or a small group of MTB-sized coastal gunboats.
