OVERVIEW: The SSN 719 Providence [Los Angeles Class, Flight II, VLS] is a nuclear-powered fast attack submarine in service with the United States Navy. Commissioned in 2021, it represents a later variant of the Los Angeles-class, incorporating improvements in stealth, sensor technology, and weapons capabilities, including the addition of a vertical launch system (VLS).

DETAILS:
The Los Angeles-class was conceived as a high-performance replacement for the preceding Sturgeon-class submarines, intended to counter the evolving Soviet submarine threat during the Cold War. The class emphasizes high speed, advanced sensor suites, and a diverse weapons payload, enabling it to perform a wide range of missions. The Flight II variants, such as the Providence, incorporate refinements based on operational experience and technological advancements. A key enhancement is the inclusion of a 12-cell Mk45 Vertical Launch System (VLS) for Tomahawk cruise missiles, significantly increasing the submarine's strike capability against land-based targets. The design incorporates noise reduction measures to improve acoustic stealth, a crucial attribute for evading detection in anti-submarine warfare (ASW) operations.

The Providence is primarily designed for anti-submarine warfare (ASW), anti-surface warfare (ASuW), and strike warfare. Its advanced sensors, including the AN/BQQ-5E(V)3 sonar suite with the BQS-13 spherical array and AN/BQS-15 close-range sonar, provide a comprehensive underwater acoustic picture, enabling the detection, tracking, and engagement of enemy submarines and surface vessels. The VLS allows the submarine to launch Tomahawk land-attack missiles, providing a potent capability for striking strategic targets ashore. The 533mm Mk67 torpedo tubes offer a flexible means of delivering a variety of ordnance, including Mk48 ADCAP torpedoes for ASW and ASuW engagements, as well as mines for covert offensive operations.

The Providence’s sensor suite provides a robust detection and analysis capability across the electromagnetic and acoustic spectrums. The AN/BLQ-10(V)2 electronic support measures (ESM) system allows for the detection and identification of radar emissions, providing situational awareness and supporting electronic warfare operations. The AN/WLR-9A radar warning receiver further enhances situational awareness by detecting and analyzing radar signals. The installation of the AN/TB-29A towed array provides increased low-frequency detection ranges, improving ASW effectiveness. Additionally, the AN/TB-34 thin line towed array enhances close in detection and localization. The Type 18 Periscope SUBIS Mod provides advanced optical and electronic imaging capabilities for surface observation and targeting. The AN/BPS-15A radar allows for surface navigation and target detection when surfaced.
