The mission of the Air Force Intercontinental Ballistic Missile Fuze Modernization program is to develop and produce a form, fit, functional replacement Mk21 Arming and Fuzing Assembly for the legacy Mk21 fuze, which is utilized with the W87 warhead.The Air Force ICBM Minuteman III MMIII fuzes require recapitalization due to the legacy fuze being three times past the original design life. In MMIII sustainment, there is an ongoing refurbishment program however, this activity will not meet fuze quantity requirements under the current known force structure. The Mk21 replacement fuze is being designed for a 30-year design life which will meet current and future Combatant Command ICBM needs for MMIII and Ground Based Strategic Deterrent. The Air Force is leveraging the Navys Mk5 Alteration 370 program to maximize commonality and achieve cost savingsavoidance over the lifecycle.
