The US Navy has taken another step toward extending the service life and combat relevance of its MH-60 Seahawk fleet by bringing multiple defense companies into a prototype modernization effort expected to support operations through 2050.Sierra Nevada Corporation, Lockheed Martin Rotary and Mission Systems, Rockwell Collins, and Technology Security Associates have been assigned complementary technical roles. Their work will address aircraft integration, mission-critical avionics, digital systems, and validation of open architectures.The H-60 Multi-Mission Helicopter Program Office is managing the initiative with support from the Royal Australian Navy. The opening phase will concentrate on preliminary engineering designs for flight-critical avionics and the helicopter’s digital backbone. It will also prepare aircraft for upcoming demonstrations and testing. A subsequent phase will move toward prototype production and verification.Digital engineering is expected to play a central role by enabling engineers to model systems before extensive physical testing begins. At the same time, Modular Open Systems Approach standards will make it easier to incorporate emerging technologies without requiring extensive changes to the aircraft’s basic architecture.The approach could serve as a model for future vertical-lift programs where rapid technology insertion and long-term adaptability are important requirements.The Seahawk’s history dates to the Navy’s search for a replacement for the SH-2 Seasprite during the 1970s. The resulting SH-60B, derived from the UH-60 Black Hawk, entered service in 1984 and established the foundation for today’s MH-60 family.Modern MH-60R helicopters are optimized for submarine hunting, surface warfare, electronic warfare, and command functions. MH-60S aircraft perform a broader range of missions, including mine countermeasures, rescue operations, special operations, and surface warfare.The government is using an Other Transaction Authority mechanism through the Naval Aviation Systems Consortium to work with the selected companies. Formal agreements will be finalized following negotiations and completion of the Phase 1 work requirements.
