OVERVIEW: The S 139 Hamza [Khalid Class, Agosta 90B] is a diesel-electric attack submarine (SSK) operated by the Pakistan Navy. Commissioned in 2021, it represents the latest iteration of the Agosta 90B design, incorporating improvements to sensor suites and potentially other systems relative to earlier boats of the class.

DETAILS: The Agosta 90B class submarine is the result of a collaboration between France and Pakistan, with the design originating from the French Agosta 70 class but incorporating significant upgrades. Pakistan sought a capable submarine to enhance its naval capabilities and provide a credible deterrent in the Indian Ocean. The Hamza represents the culmination of this program, built with technology transfer agreements that allowed for significant Pakistani involvement in the construction process. The design emphasizes quiet operation to enhance its ability to evade detection in littoral environments. This class has consistently been upgraded to retain its effectiveness against modern threats. The procurement and integration of advanced sensors and weapons were key objectives, contributing to the submarine's overall combat capability.

The Hamza's primary roles encompass anti-submarine warfare (ASW), anti-surface warfare (ASuW), and area denial operations. Its advanced sensor suite, particularly the TSM 2233M Scylla sonar system which features both a hull-mounted active/passive sonar (DSUV 2H) and a towed array sonar (DUUA 2D), provides a significant advantage in detecting and tracking both surface and subsurface targets. The installation of the SharpEye X-band radar allows for improved surface surveillance and navigation capabilities in congested waters. The DR 3000U radar intercept receiver enhances the submarine's situational awareness by detecting and analyzing enemy radar emissions. The GIDS SLTA (Submarine Laser Threat Assessment) system provides a crucial capability for identifying and responding to laser rangefinders and designators used by enemy platforms. The platform is also capable of supporting covert insertion/extraction of special operations forces, though the extent of equipment for this is classified.

The Hamza's operational effectiveness is further enhanced by its modern armament and countermeasures. The 533mm torpedo tubes provide the capability to launch a variety of torpedoes and potentially anti-ship missiles, enabling it to engage both surface combatants and enemy submarines. The integration of the Zargana countermeasure system provides a layered defense against incoming torpedoes, increasing the submarine's survivability in a hostile environment. The combination of advanced sensors, potent weaponry, and a relatively quiet design makes the S 139 Hamza a formidable asset for the Pakistan Navy.
