Raytheon has secured a $380.8 million contract modification from the US Navy to modernize Tomahawk Block IV cruise missiles and recertify them to the Block V standard, advancing the Navy’s long-range strike modernization program. The award raises the total value of the contract, first announced in late 2024, to approximately $476.5 million.
The expanded scope of work covers Lot Five and Lot Six Tomahawk missiles intended for service with the US Army, US Marine Corps, and allied operators including Australia and Japan. Contract activities will be concentrated at Raytheon’s sites in Tucson, Arizona, and Boulder, Colorado, with completion scheduled for April 2029. The program includes depot-level refurbishment, modernization efforts, and the provision of supporting hardware and spare components.
The Block V upgrade focuses on extending the operational lifespan of existing Tomahawk inventories while integrating new capabilities to counter advanced air defenses and electronic warfare threats. First fielded in 2021, the Block V variant introduces improved navigation accuracy, upgraded communications, and enhanced resistance to electronic countermeasures.
Among the key enhancements, the Block Va maritime strike variant adds a seeker capable of engaging moving surface targets, while the Block Vb variant incorporates the Joint Multiple Effects Warhead System, increasing effectiveness against hardened and high-value targets. Although the missile’s precise range is undisclosed, it is believed to exceed 1,000 miles, reinforcing Tomahawk’s role as a cornerstone of US and allied long-range strike capability.
