The new Massive Ordnance Penetrator (MOP) contract has been awarded to Applied Research Associates (ARA) for a two-year prototype design, according to the outlet.
Boeing, which originally developed the MOP, will team up with ARA for the design and full integration of new features, it added in an article on Monday.
The bombs the United States used against Iranian nuclear sites in Fordow, Natanz and Isfahan in a surprise attack on June 22 were GBU-57 MOPs.
The GBU-57 is a 30,000-pound GPS-guided bunker buster designed to destroy hardened and deeply buried nuclear facilities which is carried by the B-2 Spirit bomber.
Its first combat use came in the June strikes in the strikes dubbed Operation Midnight Hammer, when the Air Force dropped 12 bombs on the Fordow nuclear site alone.
The successor MOP, called the Next Generation Penetrator (NGP_ will focus on deeper penetration and reduced weight. Unlike the GBU-57, it will not exceed 22,000 pounds, and its guidance system will remain effective even if the enemy jams or disables GPS.
