The squadron operates the MH-60R Seahawk in roles including anti-submarine warfare and anti-surface warfare, supporting USS Theodore Roosevelt (CVN-71), USS Nimitz (CVN-68), and other carrier strike groups during patrols in the Pacific Ocean and Indian Ocean. HSM-70 personnel regularly train with allied forces such as the Royal Australian Navy, Japan Maritime Self-Defense Force, and Royal Navy as part of multinational exercises like RIMPAC and Talisman Saber.
Overview
HSM-70 functions as a rotary-wing component of United States Navy Carrier Air Wing operations, integrating with platforms such as F/A-18E/F Super Hornet, EA-18G Growler, and E-2D Hawkeye to execute maritime interdiction and littoral surveillance. The squadron's mission complements shipboard assets including Arleigh Burke-class destroyer, Ticonderoga-class cruiser, and Los Angeles-class submarine units by providing airborne anti-submarine and targeting capabilities. HSM-70 maintains readiness cycles aligned with Carrier Strike Group deployment schedules and naval aviation training protocols administered by Commander, Naval Air Forces.
History
HSM-70 was established in the late 2000s as part of a reorganization that transitioned legacy helicopter squadrons into the HSM designator to better support Carrier Air Wing requirements and the introduction of the MH-60R Seahawk. Early detachments deployed aboard USS John C. Stennis (CVN-74), USS Ronald Reagan (CVN-76), and USS Carl Vinson (CVN-70) for Western Pacific operations including freedom of navigation transits near South China Sea hotspots and cooperative patrols alongside Republic of Korea Navy units. The squadron participated in humanitarian assistance and disaster relief missions coordinated with United States Pacific Command and partnered with organizations such as United Nations agencies during regional crises.
Organization and Structure
HSM-70 is organized into flight crews, maintenance divisions, and administrative support sections consistent with Helicopter Maritime Strike Squadron templates under Naval Aviation doctrine. Leadership includes a commanding officer, executive officer, and senior enlisted advisor, who coordinate with Carrier Air Wing command and shipboard aviation detachments on embarked deployments aboard aircraft carrier. The squadron's maintenance structure works closely with Naval Air Systems Command supply chains and leverages spare parts managed through Fleet Readiness Centers and Naval Supply Systems Command logistics to sustain MH-60R sortie generation.
Aircraft and Equipment
The squadron operates the MH-60R Seahawk configured with dipping sonar, airborne active sonar, sonobuoy launchers, and multi-mode radar for anti-submarine and surface warfare missions. HSM-70 aircrews employ weapons such as the Mk 54 torpedo, AGM-114 Hellfire, and crew-served sensors integrated with the AQS-22 system and shipboard combat systems like Aegis Combat System and AN/SPY-1. Mission systems are supported by maintenance protocols from Naval Aviation Maintenance Program standards and are interoperable with command-and-control networks including Link 16 and Cooperative Engagement Capability during joint operations.
Operations and Deployments
HSM-70 deploys embarked on aircraft carriers and amphibious ships for carrier strike group operations, counter-piracy patrols, and maritime security operations alongside multinational task forces such as Combined Task Force 151 and Task Force 71. Past deployments included participation in RIMPAC exercises with the Canadian Forces and Royal New Zealand Navy, bilateral exercises with Philippine Navy units, and support for freedom of navigation operations backed by United States Indo-Pacific Command. The squadron also conducts training exchanges with United States Coast Guard units for search and rescue and maritime interdiction missions.
Insignia and Traditions
The squadron emblem features a stylized Spartan helmet and trident motifs reflecting maritime strike heritage and classical warrior iconography associated with units like the United States Marine Corps scout units and carrier-based aviation traditions. HSM-70 observes naval aviation rites such as cross-decking ceremonies, change of command traditions recognized by Chief of Naval Operations guidance, and commemorations tied to historic events like Battle of Midway anniversaries when deployed in Pacific theaters. Unit awards and recognitions have been documented within Navy Unit Commendation and Meritorious Unit Commendation frameworks.
