USN reveals JMEWS warhead upgrade plan for Tomahawk Block IV

13 December 2017

The US Navy (USN) is advancing plans to introduce a multi-effect warhead into the RGM/UGM-109E Tomahawk Block IV cruise missile as part of the weapon's forthcoming mid-life recertification.

In a pre-solicitation notice published on 8 December, the Naval Air Systems Command (NAVAIR) outlined the requirement for fiscal year 2019-23 (FY 2019-32) Joint Multiple Effects Warhead System (JMEWS) Engineering and Manufacturing Development (EMD) over a 44-month period. The intention is that Raytheon Missile Systems will be sole-sourced for the design, integration, testing, and evaluation of JMEWS kits to be installed in Tomahawk Block IV All-Up-Round missiles.

JMEWS, which was the subject of a Joint Capabilities Technology Demonstration (JCTD) completed in 2012, is essentially a shaped charge/follow through design.
