Features
As of 2008, the Gotland-class attack submarine is one of the most modern submarines of the Swedish Navy in service, mainly designed for submarine missions such as antiship/antisubmarine warfare, collecting of intelligence (communications intelligence (COMINT), electronic signals intelligence (ELINT)), forward surveillance, special operations, and mine-laying tasks.[2]
On the water surface, the submarine is powered by two sets of
Kockums touts extreme manoeuvrability for this class due to the hull design and a well-placed X rudder. The X rudder provides four control surfaces, along with two mounted on the sail, which enables sharp turns and the ability to operate very close to the seabed. Ship automation and computerized steering allow a single operator to steer the submarine in depth and course, which also results in a smaller crew complement, leading to good accommodation standards and low operating costs.[3]
The class has many features that enhance stealth, helping it to remain undetected. All shipboard machinery is isolated and mounted on rubber dampeners to reduce vibrations and noises; a

Overhaul
Initial discussions
In March 2013, Kockums received an initial order for an overhaul for two of the Gotland-class submarines. The overhaul was expected to be completed by 2017. With these upgrades, the submarines would be able to remain in active duty until after 2025.[15] On 2 April 2014, the Swedish defence minister, insisting on the importance of submarines to the security of Sweden, announced the Government's intent to upgrade two of the Gotland-class vessels, as well as purchase two new "stealth" submarines of another type.[16]
Mid-life upgrade contract
Negotiations concluded on 30 June 2015 with the signature of a contract between Sweden's
