Poland signs for three Saab A26 submarines

Poland will sign a contract on 29 June for three Saab A26 submarines, diesel-electric boats built for stealth in shallow Baltic waters (Defence24, Euronews). The deal ends roughly three decades of procurement failure. The purchase rebuilds a military specialty: trained crews, maintenance know-how, and the people and parts to keep submarines at sea, all of which Poland is close to losing entirely.

What Poland Is Actually Buying

The A26 is a 66-metre boat equipped with air-independent propulsion, a system that lets a conventional submarine stay underwater for weeks without surfacing to recharge batteries. It carries torpedo tubes and a modular bay for special forces or unmanned underwater vehicles (Marine Poland). Sweden's Saab designed it for exactly Poland's operating environment: shallow seas, dense shipping lanes, coastal noise, and short distances between NATO and Russian naval areas (Saab).

The contract goes beyond hulls. It includes crew training and investment in Polish shipyards so that Warsaw can eventually maintain and repair the boats domestically, without depending on Swedish facilities in wartime (Defence24).

The most urgent element may be a bridge lease of an older Swedish Södermanland-class boat to keep Polish submariners trained while the A26s are built. Poland's submarine force has eroded to a single vessel, ORP Orzeł, commissioned in 1985 (Fakt). The first A26 is expected between 2030 and 2032 (Rzeczpospolita). Without a gap-filler, the navy risks losing its last qualified submarine crews before a new boat ever arrives.

A NATO Sea That Still Lacks NATO Submarines

Since Finland and Sweden joined NATO in 2023 and 2024, every Baltic coastal state except Russia belongs to the alliance (Puolustusvoimat). That reshaped the strategic picture, but alliance membership alone does not produce deterrence. NATO sets up command structures and planning frameworks. It does not buy, crew, or maintain submarines on any nation's behalf. Each country must deliver its own platforms and trained people.

Poland is plugging a national gap into a Nordic-Baltic underwater environment where Sweden already has decades of operational experience (Marine Poland). A quiet A26 can force an adversary to assume an unseen NATO platform is lurking near chokepoints and port approaches, complicating hostile planning (BAE Systems).

Industrial politics shaped the outcome. German-language coverage framed the result as a loss for Thyssenkrupp Marine Systems, which also competed (Euronews DE). No public scoring has explained why Sweden won. The likelier account: Saab offered what Poland needed most, a Baltic-specialised design, a gap-filler boat to prevent crew extinction, and a path to sovereign repair capacity (Rzeczpospolita).

The Cable Question Submarines Cannot Answer Alone

The deal lands as Baltic underwater infrastructure faces grey-zone threats, from anchor-dragging to suspected sabotage of data cables, power interconnectors, and pipelines (FIIA). Officials may link submarines to infrastructure protection, but the connection is indirect. A26 boats add covert surveillance and deterrent uncertainty. Actual cable defence requires persistent sensing, coast guards, drones, attribution tools, and repair ships (War on the Rocks). Finland tested one concrete approach: using distributed acoustic sensing on existing cables to detect anchor threats before damage occurs (Elisa).

The EU is building its own layer. On 23 June, the European Commission funded the first two Regional Cable Hubs, including €2.5 million for a Baltic hub and a separate €40 million call for rapid submarine-cable repair capacity (European Commission, 2EU Brussels). Finland coordinates the Baltic hub alongside Denmark, Germany, Estonia, Latvia, and Sweden. Poland is not among the participants, buying undersea military capability on a bilateral Swedish track while the EU's first cable-security coordination runs through a different group.

Sunday's contract signing closes a three-decade procurement gap. The harder question is whether Poland's three boats get wired into the wider architecture of sensors, patrols, repair teams, and NATO command before the next cable incident forces the answer.
