Poland signs a final contract worth about $4.8 billion (47 billion kronor) with Saab AB for the purchase of three Saab A26 submarines, according to multiple outlets. The agreement is presented as a major, long-term procurement intended to strengthen the Polish Navy’s undersea capabilities, particularly for operations in the Baltic Sea, a region highlighted by Swedish leadership as important to collective security across NATO. The Swedish Prime Minister Ulf Kristersson characterizes the deal as large and long-term and links it to broader allied security. Defense News also reports that the procurement package includes an additional, separate arrangement for a near-term “gap filler” boat. That vessel is intended to help Poland bridge capability gaps for Baltic Sea missions while also supporting training for Polish sailors until the submarines are delivered.
