Stockholm (PCGT)

The Stockholm class is a pair of warships of the Swedish Navy. Built as corvettes in Karlskrona 1984–1985, they are armed with four RBS15 anti-ship missiles, one 57 mm cannon and several machine guns. In 2017 the two units in the class were rebuilt and are now serving as patrol boats. The option to carry anti-ship missiles does however remain.

Developed in the early 1980s to counter foreign submarine incursions in Swedish territorial waters, the Stockholm-class was designed as a heavily armed vessel optimized for anti-submarine and anti-surface warfare in the Baltic Sea. The lead ship, HMS Stockholm, entered service with the Swedish Navy in 1985, showcasing advanced domestic naval engineering and early stealth-conscious design elements. Following a major modernization to ensure NATO interoperability, the vessel was deployed to the Gulf of Aden in 2009 for Operation Atalanta, where it successfully conducted anti-piracy escort missions. In 2016, the ship was reclassified as a patrol vessel after its heavy anti-ship missiles were removed, and it continues to serve the Swedish Navy in coastal surveillance and training roles.
