Saab president and CEO Micael Johansson said: “Saab is currently building the world’s most advanced conventional submarines for Sweden. Following excellent cooperation between Saab and FMV we have ensured that Sweden has a state-of-the-art underwater capability which will contribute to keeping our nation’s waters safe for decades to come.”

Construction of Sweden’s two A26 Blekinge-class submarines has been in progress at Saab’s Kockum Shipyard since September 2015.

In late 2023, Saab pledged to collaborate with FMV on advancing underwater capability concepts.

The company plans to enhance existing solutions with new technologies, which are anticipated to be incorporated into the Royal Swedish Navy’s two A26 submarines.

The submarines feature a modular hull constructed from specialised steels, ensuring robust seakeeping abilities and operational efficiency.

Their X-rudder configuration is said to allow exceptional manoeuvrability with four independently controlled surfaces.

Moreover, the submarines demand low operational and maintenance costs.

Designed as a formidable intelligence platform, the Blekinge-class submarine can operate both autonomously and in conjunction with Saab’s Autonomous Ocean Drone and other uncrewed underwater vehicles.

It is equipped to engage in sea-bed warfare, capable of resting on the ocean floor and deploying underwater vehicles or special forces for missions like protecting critical infrastructure.

The submarine incorporates baseline autonomous capabilities, including vessel control through the Autonomous Ocean Core system.

In February 2025, Saab launched the third and final Gotland-class (A19) submarine, HMS Halland, following a mid-life upgrade at the Karlskrona shipyard.
