**OVERVIEW:** The A 26 Blekinge is a diesel-electric submarine currently under construction for the Swedish Navy. The class represents a significant advancement in Swedish submarine design, focusing on modularity, stealth, and operational flexibility in the Baltic Sea environment and beyond.

**DETAILS:**
The A 26 program was initiated to replace the aging *Södermanland*-class submarines and address evolving strategic requirements. Saab Kockums, the primary contractor, designed the *Blekinge*-class incorporating a modular design philosophy. This allows for easier upgrades and adaptations throughout the submarine's operational life. The modular construction also facilitates the integration of new technologies as they emerge, maintaining the platform's relevance against future threats. A key design element is a focus on low acoustic, magnetic, and infrared signatures, enhancing the submarine's ability to operate undetected in littoral environments. Furthermore, the design emphasizes crew comfort and habitability during extended deployments. The program has faced delays, but the lead boat, *Blekinge*, is currently undergoing sea trials.

The primary roles envisioned for the *Blekinge*-class are anti-submarine warfare (ASW), anti-surface warfare (ASuW), and intelligence, surveillance, and reconnaissance (ISR) operations. Its quiet operation makes it particularly suited for ASW in the shallow, complex waters of the Baltic Sea. The boat is also designed to conduct special operations missions, facilitated by a large multi-mission portal (MMP) capable of deploying divers, remotely operated vehicles (ROVs), or other specialized equipment. This feature expands the operational envelope beyond traditional submarine warfare roles. Additionally, the *Blekinge*-class is equipped to deploy mines and conduct covert surveillance missions, providing a versatile platform for a range of naval and strategic tasks.

The *Blekinge*-class integrates a suite of advanced sensors and weapon systems to achieve its mission objectives. The Scanter radar provides surface surveillance and navigation capabilities. The CSU 90-2 hull-mounted and flank array sonars, along with the IPS CSU 90 integrated sonar system, offer comprehensive underwater acoustic awareness. The ES-3701 Seawatch electronic support measures (ESM) system allows for passive detection and identification of radar emissions. The Series 30 SMS Photonics Mast provides high-resolution visual and infrared imagery. The SA9510S electronic warfare suite offers additional capabilities in signal analysis and countermeasures. Armament includes both 533mm and 400mm torpedo tubes, providing flexibility in engaging a variety of targets. A signal ejector allows for the deployment of countermeasures and communication buoys.
