A Lockheed Missiles and Fire Control spokesman said the new version is "part of a planned upgrade" of the JASSM "family of missiles" which includes the baseline AGM-158A JASSM, the AGM-158B JASSM-ER, and the Long-Range Anti-Ship Missile AGM-158C...
The upgrade includes a new missile control unit computer, "which will support the other planned capabilities," the spokesman said. These include "new wing designs to increase standoff range through aerodynamic efficiency, and a new GPS unit to further advance our level of protection."

Lockheed Martin (NYSE: LMT) received an Undefinitized Contracting Action for $37.7 million from the U.S. Air Force for continued development of a new wing design for the Joint Air-to-Surface Standoff Missile – Extended Range (JASSM-ER).
The new wing design will add greater range to the cruise missile, which currently has a range of more than 500 nautical miles. Analysis on an enhanced wing design began in March 2016.
"We've developed a novel design that provides additional standoff range to further increase pilot survivability in an Anti-Access-Area Denial threat environment," said Jason Denney, program director for Long Range Strike Systems at Lockheed Martin Missiles and Fire Control. "Our customers trust our already proven design and we look forward to enhancing its capabilities for warfighters."
