Gotland Class submarine

The Gotland Class - one of the world's most modern conventional submarine. It is designed and built to meet all possible submarine missions: anti-shipping operations, ASW-missions, forward surveillance, special operations and mine-laying tasks.


The Gotland Class can carry a powerful array of wireguided and homing weapons, including newly developed multipurpose homing torpedoes, missiles and mines.

The Gotland was the world's first submarine class in operation with an air independent propulsion (AIP) system. The Stirling AIP system, combined with a number of unique features including overall low signatures, extreme shock resistance and a powerful combat system, provides the ultimate in non-nuclear submarine technology.

Three submarines of the Gotland class, HMS Gotland, HMS Uppland and HMS Halland are now in service with the Royal Swedish Navy.

The Gotland Class combat system and sensor suite are carefully selected for submarine warfare of today and for the future. Detection, identification, weapon launching and control are performed by the combat system at distances well beyond the horizon.

On board, the complete suite of equipment incorporates the latest of technologies. There is, for example, an innovative, newly developed sonar and fire control system incorporating powerful new means for target motion analysis for the determination of target course, speed and position.

The combat system integrates data processing with weapon control. All types of sensors, navigation and weapon control equipment, integrating consoles and tactical programmes are included in the system.
