Designing 69 Meters Littoral Mission Ship Based on the 60 Meters Fast Patrol Boat Platform to Improve Multi-Task Warfare

Abstract

60 meters fast patrol boat class is well known as one of the successful programs in the build of local warship in the national shipyards. Due to the higher tension in the South China Sea recently, therefore, it is urgently to have some better ships both quantitatively and qualitatively. To reduce procurements costs and shorten the delivery time then an LMS type with a length of 69 meters would be proposed based on the proven design of 60 meters FPB. Improvement of the platform not only about its size and capacity but also multi-task missions. The LMS will support missions of patrolling and intercepting as a fast patrol craft, moreover additional tasks including anti-surface warfare, mines-warfare, hydrography and intelligence, surveillance, and reconnaissance (ISR), also bio & chemical warfare duties. LMS will have a low radar cross-section by improving its stealth design and the addition of a helideck to accommodate a medium-sized helicopter. Ship able carries up to three standard ISO-containers as complementary logistics when the deck not being occupied by helicopter. LMS needs only 20% more engine power when its draught is 0.1 m higher and 21.5% more displacement compare with the FPB at a similar speed of 24 knots.
