Visby class and Swedish Baltic defence

The class is designed for operations close to Sweden but carries enough offensive equipment to dominate a constrained Baltic sea area. Its battery includes anti-ship missiles, heavyweight torpedoes for the local environment, mines, depth charges, and anti-submarine weapons. The lack of embarked surface-to-air missiles reflected an expectation of nearby Swedish air cover and a preference for avoiding detection rather than mounting a large active defensive battery. The combination of stealth and concentrated weapons points to a navy planning to fight locally but aggressively. Later passive thermal and infrared sensors could alter that calculation by making a short-range missile fit less dependent on active emissions.
