Orbital ATK and IMI Systems Partner to Jointly Introduce New Weapons Technology for the U.S.

Orbital ATK (NYSE: OA), a global leader in aerospace and defense technologies, and IMI Systems Ltd. have announced a teaming agreement in which Orbital ATK will produce and supply a U.S. version of IMI’s 500-lb Multi-Purpose Rigid Bomb (MPR500) and the MPR family of bombs for the United States.

With today’s warfighting landscape shifting to an increasingly asymmetric environment, there is a growing demand for high versatility, high reliability and low collateral damage precision weapons with a penetration capability. According to IMI, the MPR500 is similar in form and fit to the MK-82 and offers proven penetration capability and controlled fragmentation for a concentrated blast.

“Our first initiative in this agreement will be exploring how MPR500, a combat proven technology, can be transitioned into an economical and rapidly fielded solution for our U.S. warfighters,” said Pat Nolan, Vice President and General Manager of Missile Products within Orbital ATK’s Defense Systems Group. “We are hopeful that this relationship will lead to future product enhancements and additional opportunities for Orbital ATK and IMI Systems to collaborate.”

Orbital ATK’s Defense Systems Group is an industry leader in providing innovative and affordable precision and strike weapons, advanced propulsion and hypersonics, missile components across air-, sea- and land-based systems, ammunition and related energetic products.
