Malaysia has a modest submarine force consisting of two Scorpenes: KD Tunku Abdul Rahman, commissioned in January 2009 and KD Tun Abdul Razak, commissioned in December 2009. Malaysia occasionally has low level naval confrontations with the Indonesia Navy over territorial boundaries and seabed oil rights (see my post about latest Ambalat flare up). Malaysia would also be sensitive about Singapore's growing submarine fleet (including Singapore's order in late 2013 of 2 HDW 218SGs). Malaysia is also in competition with countries in the northwest Pacific for resources in the South China Sea. To meet competition from Indonesia Malaysia's two Scorpenes are based at Sepanggar, Sabah.
Scorpenes, like Australia's Collins, are attack submarines, with no capability to search for or recover crashed aircraft. Unlike most countries in the region Singapore has a highly specialised Submarines Support and Rescue Vessel (SSRV) the MV Swift Rescue. SSRVs are very expensive and rarely used - which explains why so few small to medium size navies have them.

"PORT KLANG, Malaysia — Malaysia's first ever submarine was delivered Thursday to colourful fanfare and a royal visitor, in an acquisition that the government said "completes" the country's navy.
Naval officials said the submarine would be based in Sabah state, on Borneo island, where it will undergo fine-tuning before it is deployed in search and rescue and military exercises.
