The U.S. Navy has awarded Raytheon a $380.8 million contract modification to upgrade and recertify Tomahawk Block IV cruise missiles to the more advanced Block V configuration.
The modification confirms a contract first announced in December 2024 and raises the total program value to $476.5 million. It also broadens the scope of work to include Lot Five and Lot Six missiles intended for the U.S. Army, U.S. Marine Corps, Australia, and Japan.
Most of the work will be carried out in Tucson, Arizona, accounting for roughly 30 percent of the effort, and in Boulder, Colorado, which will handle about 28 percent. Contract completion is scheduled for April 2029.
The effort covers depot-level recertification and modernization activities, along with the supply of associated hardware, spare parts, and rotable pool assets. The goal is to extend the operational life of existing Tomahawk inventories while enhancing performance in contested and electronically dense environments.
The Tomahawk Block V family, introduced in 2021, features upgraded warheads, navigation systems, and communications to improve survivability against electronic countermeasures. The Block Va maritime strike variant adds a new seeker designed to engage moving surface targets, while the Block Vb variant replaces the legacy warhead with the Joint Multiple Effects Warhead System to increase effectiveness against hardened and complex targets.
While the missile’s exact range remains classified, it is expected to be capable of engaging surface targets at distances beyond 1,000 miles.
