## SSBN 726 Ohio

**OVERVIEW:** The SSBN 726 *Ohio* is a United States Navy nuclear-powered ballistic missile submarine (SSBN) of the *Ohio*-class. Commissioned in 1992, it represents a key component of the US Navy's strategic nuclear deterrent force.

**DETAILS:**

The *Ohio*-class was conceived in the early 1970s as a replacement for the aging *George Washington*- and *Ethan Allen*-class SSBNs. The design prioritized stealth, survivability, and the ability to carry a large number of ballistic missiles. The *Ohio*-class hulls are significantly larger than their predecessors, allowing for quieter operation and improved internal arrangement. The program's goal was to provide a secure and credible second-strike capability, ensuring nuclear deterrence through the Cold War and beyond. The large missile capacity, combined with advanced quieting technology, allowed these submarines to operate undetected for extended periods, posing a significant challenge to Soviet anti-submarine warfare efforts. The *Ohio*-class design also incorporated modular construction techniques to expedite the building process and facilitate future upgrades.

The primary role of the SSBN 726 *Ohio* is strategic nuclear deterrence, achieved through the deployment of submarine-launched ballistic missiles (SLBMs). The platform’s stealth and endurance allow it to patrol vast ocean areas undetected, presenting a credible threat to potential adversaries. While primarily focused on strategic deterrence, the vessel also possesses limited self-defense capabilities against submarine and surface threats. The 533mm torpedo tubes allow the submarine to engage hostile submarines or surface vessels if necessary. Furthermore, the integrated sonar suite enables the *Ohio* to conduct surveillance and gather intelligence while on patrol. The signal ejector provides means for covert communication.

The SSBN 726 *Ohio* is equipped with an array of advanced sensors designed to enhance its situational awareness. The AN/BQQ-6 integrated sonar suite provides comprehensive detection, tracking, and classification capabilities, enabling the submarine to identify and localize potential threats. The AN/BQR-19 towed array sonar further enhances the submarine's ability to detect distant targets, while the AN/BQR-15A provides close-range detection capabilities. The AN/BPS-15A radar provides surface search and navigation capabilities. Electronic support measures (ESM) systems, including the AN/WLR-8(V)5 and AN/WLR-10, allow the submarine to detect and analyze enemy radar emissions. The AN/WLR-17 system provides enhanced electronic intelligence gathering capabilities. The inclusion of both optical and low-light television (LLTV) periscopes allows for visual observation in varying light conditions. The Trident C4 SLBM provides the primary offensive capability, while the Mk68 torpedo tubes offer a secondary means of defense.
