Raytheon has secured a $380.8 million contract modification from the U.S. Navy to modernize and recertify Tomahawk Block IV cruise missiles to the Block V standard.
The award formalizes a deal announced in December 2024, bringing the total contract value to $476.5 million, and expands modernization work for Lot Five and Lot Six missiles to be delivered to the U.S. Army, U.S. Marine Corps, Australia, and Japan.
Contract performance will be centered primarily in Tucson, Arizona, and Boulder, Colorado, which together account for the majority of the workshare. Completion of the effort is expected by April 2029.
The contract includes depot-level refurbishment and recertification, as well as the integration of upgraded hardware, spare components, and rotable pool assets. The objective is to extend the service life of existing Tomahawk stocks while enhancing their effectiveness in highly contested electromagnetic environments.
The Block V Tomahawk family, introduced in 2021, incorporates improved navigation, communications, and warhead options to counter electronic warfare threats. The Block Va variant is optimized for maritime strike, featuring a new seeker capable of engaging moving surface vessels, while the Block Vb variant introduces the Joint Multiple Effects Warhead System to expand lethality against hardened and complex targets.
Although official range figures are not disclosed, the missile is widely assessed to have the ability to strike surface targets at ranges exceeding 1,000 miles.
