Raytheon eyes guidance sensor and processor to enable Tomahawk missile to hit moving enemy vessels at sea

PATUXENT RIVER NAS, Md. – Smart munitions experts at the Raytheon Co. are moving forward with a U.S. Navy program to retrofit the venerable Block IV Tactical Tomahawk missile for the anti-ship role with a new sensor system to enable the weapon to attack moving enemy vessels at sea.

Officials of the Naval Air Systems Command at Patuxent River Naval Air Station, Md., announced a $7.2 million order on Thursday to the Raytheon Missile Systems segment in Tucson, Ariz., to support the Maritime Strike Tomahawk (MST) rapid deployment capability.

The order calls for Raytheon to update technical data package of the guidance test set, and upgrade existing units to support the MST additions -- including hardware and software.

The Maritime Strike Tomahawk program is planned for initial operational capability in 2022, with procurement of upgrade kits continuing into 2023. Raytheon has been sole Tactical Tomahawk missile producer since 1994.

Raytheon's research on this program will involve architecture and algorithm development; prototyping; modeling and simulation test analysis; modernizing test equipment; hardware and software development; captive carry build-up and test; ground launch; and testing aboard surface warships.

Raytheon will provide 32 Maritime Strike Tomahawk upgrade kits in 2020; 50 kits in 2021, and 80 kits in 2022, at an estimated cost of about $457.9 million.

Navy joint task force commanders increasingly face long-range anti-ship missiles that threaten their surface forces and potentially deny access to mission-critical areas of operation, so they need a near-term capability to counter hostile surface forces. Without this, the Navy could face loss of life or critical mission failure, Navy officials say.

The Tactical Tomahawk missile has unique flight, launch, and information-processing capabilities that a seeker modification could help meet these needs affordably, officials say. Raytheon can integrate a new sensor suite into the Tactical Tomahawk quickly, and is the only known source with the technical knowledge to update the missile quickly enough for rapid delivery to the Fleet.

Since 2012 Raytheon has spent about $55 million of its own money for studies, mock-ups, and engineering analysis to find a Tomahawk missile seeker solution with the limited space available inside the missile to accommodate seekers, ancillary equipment and the processor.

For the Maritime Strike Tomahawk, Raytheon is proposing a seeker, processor, software, and a new inertial measuring unit for terminal maneuvers. Raytheon also is redesigning the system’s power budget and system cooling.
