IW1/Mk21A

Abstract

The Mk21A Reentry Vehicle (RV) program will design, develop, produce and deploy an integrated RV capable of delivering the Interoperable Warhead 1 (IW-1) nuclear warhead when released from the Ground Based Strategic Deterrent (GBSD) Intercontinental Ballistic Missile (ICBM). The major activities in the Technology Maturation and Risk Reduction (TMRR) phase of the Mk21A RV program include 1) Government system engineering, analytics, and test capability development, 2) RV Risk Reduction, and 3) Weapon System Integration Risk Reduction. Reentry vehicle components include a high velocity nosetip, high impulse transducer, fuze, aeroshell forward section, body section and rear cover, radio frequency subsystem with antennas, RV spin-up system, inflight disconnect cable and other electrical cables. The MK21A program will include prime contractor development of applicable support equipment, data, flight test hardware, infrastructure, training materials while examining and mitigating weapon system integration risks, and any needed nuclear surety and certification and system vulnerability assessments. This program element may include necessary civilian pay expenses required to manage, execute, and deliver Mk21A RV weapon system capability. The use of such program funds would be in addition to the civilian pay expenses budgeted in program elements 0605826F, 0605827F, 0605828F, 0605829F, 0605830F, 0605831F, 0605832F, 0605833F, and 0605898F. BA7 - This program is in Budget Activity 7, Operational System Development because this budget activity includes development efforts to upgrade systems that have been fielded or have received approval for full rate production and anticipate production funding in current or subsequent fiscal year.
