At the beginning of 2015, Northrop Grumman received a contract with the U.S. Air Force to supply Minuteman III Intercontinental Ballistic Missiles. The contract is worth USD$963.5 million dollars over 5 years with an initial award value of USD$4.4 million. They are the sole award recipient and will provide an indefinite quantity of missiles. This contract extends the 50-year partnership between Northrop Grumman and the U.S. Air Force on ICBMs. Northrop Grumman is uniquely qualified to perform the necessary activities because of their 17-year experience as the ICBM prime integration contractor. The contract stipulates that Northrop will provide program management support, engineering services and emergency response. The agreement encompasses weapon system analyses, system and subsystem assessment, and technical advisement and assistance to the ICBM Systems Directorate on ground systems-related programs, risk management and mitigation. The Minuteman-III was first deployed in 1970. At the time, it was armed with a W62 warhead with a yield of 170-kilotons of TNT. It was also the first Multiple Independently Target-able Reentry Vehicles missile. In other words, a single missile is able to target 3 different locations.
