Cosmos Class MG110
The Naval Special Services Group (SSGN), numbering 1,000 marines, is responsible for conducting unconventional operations at sea and along the shoreline. Delivery or insertion of maritime special forces includes fixed- wing/helicopter low-level parachuting, light craft beaching and underwater conveyance, for which the navy operates at least three Cosmos Class MG110 miniature submarines (SSI) and some swimmer- delivery vehicles.
On the basis of design developed by PN Dockyard, this type of mini submarine has been constructed at PN Dockyard. These mini-submarines can be used for various purposes like attacking enemy units in harbour with Frogmen/Charriots, at sea with torpedoes, at shore installations by commandos etc. other uses include mine laying, defensive barrier in shallow waters, advance pickets duties, intelligence gathering etc.
Although the Italian Navy pioneered the use of human torpedoes (known today as swimmer delivery vehicles or SDVs), in today's Italian Navy there are no midgets. However Cosmos of Livorno has sold a number of midgets abroad. The SX 404 type sold to Pakistan in the early 1970s have been replaced by three [or possibly four] Italian-built SX-756-class midget submarines, delivered in 1988. These displace 40 tons and are capable of diving to a depth of 100m. They can carry six swimmers and two SDVs, as well as 2 tons of explosives.
X-Craft 908 P/A as Shallow Water Attack Submarine(SWAS) is used to carryout mine laying torpedo attack, frogman operations and commando landing. The contract of these mini submarines was signed with Italian firm M/s COSMOS in 1986. First of these craft was brought to Pakistan in semi knock down condition in 1988. Subsequently all X-Craft were assembled in Pakistan with TOT. Presently, X-Craft are being operated under COMSUBS alongwith other conventional submarines.
