**OVERVIEW:** The SS 22 *Carrera* [Scorpene] is a diesel-electric attack submarine operated by the Chilean Navy.

**DETAILS:**

The *Scorpene* class submarines represent a collaborative Franco-Spanish venture intended to produce a modern, cost-effective, and exportable submarine design. The development was driven by the need for a potent yet affordable submarine for navies with diverse operational requirements. The design prioritizes stealth, incorporating advanced hydrodynamics and acoustic damping measures to minimize its acoustic signature. The class has proven successful in the export market, being acquired by several nations seeking a modern and capable submarine platform. The *Carrera*, commissioned in 2005, represents Chile's commitment to maintaining a modern and effective submarine force, allowing it to project power and maintain maritime security within its Exclusive Economic Zone (EEZ). The selection of the Scorpene class reflects a strategic decision to invest in advanced submarine technology without the associated high costs of nuclear propulsion.

The *Carrera*'s primary roles encompass anti-submarine warfare (ASW), anti-surface warfare (ASuW), intelligence, surveillance, and reconnaissance (ISR) missions, and potentially, support of special operations forces (SOF). In an ASW role, the submarine leverages its stealth and advanced sonar suite to detect and track enemy submarines. For ASuW, the *Carrera* is capable of engaging surface combatants with torpedoes. The submarine's endurance and sensor capabilities allow it to conduct long-range surveillance operations, gathering valuable intelligence in contested maritime environments. Its relatively shallow draft compared to larger submarines allows it to operate more effectively in littoral waters.

The *Carrera* is equipped with a comprehensive sensor suite to facilitate its various operational roles. The TRS 3100 Calypso III radar, further identified as the DRUA 33C variant, provides surface search and navigation capabilities. The AR-900S electronic support measures (ESM) system allows for the passive detection and identification of radar emissions from surface ships and aircraft. The TSM 2233M Scylla sonar suite, incorporating both the DSUV 2H towed array and the DUUA 2D hull-mounted array, provides long-range detection, tracking, and classification of underwater targets. The TSM 2243 fire control system integrates sensor data to provide targeting solutions for the submarine's torpedoes. The Series 30 SMS Photonics Mast replaces a traditional periscope, providing enhanced situational awareness and reducing the submarine's vulnerability to detection. The C303/S decoy launching system allows the *Carrera* to deploy countermeasures against incoming torpedoes.
