**OVERVIEW:** The S 353 *Preveze* [Type 209-1400, *Preveze/Gür* Class] is a diesel-electric submarine operated by the Turkish Naval Forces.

**DETAILS:**
The *Preveze* class represents an advanced derivative of the ubiquitous Type 209 diesel-electric submarine, specifically the 209-1400 variant. These submarines were developed to meet the Turkish Navy's requirements for a modern, capable submarine force able to operate effectively in the demanding littoral environment of the Aegean and Mediterranean Seas. The design incorporates improvements over earlier Type 209 variants, focusing on enhanced acoustic quieting, increased automation to reduce crew size, and an improved combat system. The class benefits from technology transfer agreements, allowing for significant local construction and integration of domestic subsystems, bolstering Turkey's indigenous defense industry. The naming of the class after the Battle of Preveza reflects Turkish naval history and strategic ambition.

The primary roles of the *Preveze* class are anti-submarine warfare (ASW), anti-surface warfare (ASuW), and intelligence, surveillance, and reconnaissance (ISR). The class is well-suited for covert operations, surveillance, and the protection of Turkish maritime interests. The 533mm torpedo tubes provide a significant offensive capability against surface combatants and submarines. The integration of the Zargana countermeasure system enhances survivability against torpedo threats. The *Preveze* can effectively engage in sea denial operations in key chokepoints.

The *Preveze* benefits from a sophisticated sensor suite. The FAS 3-1 sonar provides an effective active and passive detection capability. The TAS-3 towed array sonar further extends the submarine's passive detection range, crucial for ASW operations. The S 63B fire control system integrates the sensor data and manages weapon engagements. The Type 242 Sealion radar provides surface search capability. The CSU 83/1 attack console, IPS CSU 83 integrated processing system, and MAS 83 mine avoidance sonar enhance the submarine's situational awareness and operational effectiveness. The inclusion of both optical and low-light television (LLTV) periscopes allows for visual observation and target identification in varying light conditions. The signal ejector provides for the deployment of decoys and communication buoys.
