Project history

MAS430 was further development of "12-ton" SVAN boat of WWI-era. At the expense of installation of much more powerful engines the speed was significantly increased. Anti-submarine armament was presented by five small 50kg DCs and hydrophone.

MAS437 belonged to "SVAN high-speed diesel" type, diesel-engined variant of "SVAN 14-ton fast" type. Because of installation of heavier diesels she was received a little bit more larger than petrol-engined boats, but in the speed practically has not lost.
