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

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 Stirling Engine Revivaler

HSwMS Gotland (Gtd) is a defense [2] submarine of the Swedish Navy. It was the first ship of the Gotland -class, which was the first operational submarine class in the world to use air-independent propulsion in the form of Stirling engines which use liquid oxygen and diesel as the propellant.

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

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.

Saab Receives Further Order For Blekingeclass Stirling AIP Submarine For Swedish Navy

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).

Saab Receives Further Order For Blekingeclass Stirling AIP Submarine For Swedish Navy

Saab image After a first attempt made by ThyssenKrupp's owned Kockums, the A26 program was finally launched in 2015 after FMV (Swedish Defence Materiel Administration) placed an order for two new generation submarines for the Royal Swedish Navy.

1,490t Expand HMS Gotland first of class. The submarine is equipped with a Kollmorgen search-and-attack periscope. The submarines are fitted with four 21in and two 15.75in torpedo tubes. The 9SCS Mark 3 Combat Management System has three multifunction consoles. HMS Uppland.

The Stirling Engine Revivaler

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.

Submarines Resurface as Growth Business

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.

Submarino sueco classe 'Gotland' pronto para novo motor AIP Poder Naval

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.

Meet the Impressive Swedish Invention That Turned Its Submarine Fleet Into the World's Finest

The Swedish sub would be playing the adversary to America's massive constellation of anti-submarine surface combatants, helicopters, fixed wing aircraft, and especially nuclear submarines..

Swedish Navy’s HSwMS Gotland submarine completes midlife overhaul Naval Technology

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

This 1 Invention Made Swedish Submarines Among the Best The National Interest

The air-independent Stirling engine has been used in Swedish submarines for 30 years. The basic principle is still the same, but much has happened since in this area: digital control system, new generator and recovery of the residual heat in the exhaust gases to produce hot water for comfort on board are some of the measures taken.

Modern Uses of Stirling Engines

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]
