Poland and Sweden signed a €4.2 billion arms deal on June 29, 2026, for three A26 Blekinge-class submarines to be delivered between 2030 and 2038, with Poland receiving temporary use of HMS Södermanland until then. The diesel-electric submarines are designed for Baltic Sea operations and can remain underwater for days in complete silence. Poland currently operates only one aging Russian submarine, making this purchase critical to its naval modernization as NATO members strengthen defenses amid Russian aggression in Ukraine and uncertainty about US security commitments under President Trump. Saab will establish maintenance facilities in Poland operated with local companies to enhance Polish defense autonomy.
