The US Navy has awarded Raytheon a $380.8-million contract modification to modernize and recertify Tomahawk Block IV cruise missiles to the Block V standard.
The award confirms a contract announced in December 2024, bringing the total contract value to $476.5 million. It also expands the scope of work for Lot Five and Lot Six missiles destined for the US Army, US Marine Corps, Australia, and Japan.
The majority of the work will be performed in Tucson, Arizona (30 percent), and Boulder, Colorado (28 percent), with contract completion expected by April 2029.
The contract encompasses depot-level recertification and modernization, along with associated hardware, spares, and rotable pool assets.
At its core, the effort seeks to extend the service life of existing Tomahawk inventories at scale while adding capabilities to keep the missile effective in contested, electronically dense environments.
Tomahawk Block V
Introduced in 2021, the Block V family incorporates upgraded warheads, navigation, and communications to improve resilience against electronic countermeasures.
The maritime strike variant, Block Va, adds a new seeker to engage moving surface targets.
Block Vb replaces the legacy warhead with the Joint Multiple Effects Warhead System, expanding the target set with improved effects against hardened or demanding aimpoints.
Although its exact range is undisclosed, the missile is expected to be capable of striking surface vessels at distances exceeding 1,000 miles (1,609 kilometers).
