Sweden is Developing an Advanced Submarine. It was the first operational submarine class in the world to use air-independent propulsion in the form of Stirling engines which use liquid oxygen.


The Stirling Engine Revivaler

The Stirling power module V4-275R, integrated with a liquid oxygen system, is currently built for submarines for the Royal Swedish Navy and for the offshore company Comex in France. Since mid 1985 the Stirling engine system for the Swedish Navy has been successfully tested in a full-scale submarine test section.

This technology is unique to Swedish submarines" remarks Sebastian Lenander, Manager, Assembly and Testing Stirling, Saab Kockums. By heating and cooling the gas in a Stirling engine, the piston can move in a cylinder. The submarine can then use cold seawater for cooling and liquid oxygen and diesel to create the heating of the engine.

Fortunately, this did not occur in actual combat, but was simulated as part of a war game pitting a carrier task force including numerous antisubmarine escorts against HSMS Gotland, a small.


Submarines Resurface as Growth Business

The Näcken-class submarines, also known as the A14 type, were built for the Swedish Navy in the late 1970s. The boats were authorised in 1972 and the programme was completed in 1980 . All boats were built by Kockums in Karlskrona. The boats had a teardrop hull and diving depth was 150 metres (490 ft).

The Gotland class features the noise-less Stirling engines that do not need air for their propulsion, allowing them to stay underwater for weeks when needed or switching to diesel power when.


Modern Uses of Stirling Engines

The Swedish Navy was the first to operate diesel vessels using an air-independent propulsion (AIP) system based on the Stirling engine. 1 Total Submarines in Fleet: 5 Ballistic Missile Submarines ( SSBNs ): 0 Nuclear-Powered attack submarines (SSNs): 0 Diesel-electric attack submarines ( SSKs ): 5 Air-independent propulsion ( AIP) enabled: 5/5

A Stirling engine is a heat engine that is operated by the cyclic compression and expansion of air or other gas (the working fluid) between different temperatures, resulting in a net conversion of heat energy to mechanical work. [1] [2]

by Caleb Larson L Here's What You Need to Know: Quiet submarines are difficult to hunt. The Gotland-class of submarines are the pride of the Swedish Navy. They're really quiet—and are getting.

The Gotland-class submarines of the Swedish Navy are modern diesel-electric submarines, which were designed and built by the Kockums shipyard in Sweden. They are the first submarines in the world to feature a Stirling engine air-independent propulsion (AIP) system, which extends their underwater endurance from a few days to weeks. [2]

Sweden tested a Stirling engine design in a French research vessel in the 1980s and, when it worked well, they modified an older submarine to work with the new engine design. Successes there led to the construction of three brand-new submarines, all with the Stirling engine.


Sweden’s New Submarine is Probably the World’s Stealthiest The National Interest

The Gotland-class submarines of the Swedish Navy are modern diesel-electric submarines, which were designed and built by the Kockums shipyard in Sweden. They are the first submarines in the world to feature a Stirling engine air-independent propulsion system, which extends their underwater endurance from a few days to weeks. This capability had previously only been available with nuclear.

The exercises demonstrated that the Gotland was hard to locate due to the silent Stirling engines and the Swedish submarines were the subject of considerable international attention. The world's most modern submarine programme. The A26 submarine, also known as the Blekinge class submarine, currently in production at the shipyard in Karlskrona

The submarine was put into drydock and cut in two. A fully outfitted eight meter section was the inserted. SSK Gotland Class (type A19) Stirling powered submarines. The Stirling Air Independent Propulsion (AIP) is now installed in three, Swedish Navy, Gotland Class submarines to satisfy the energy needs for prolonged underwater missions.
