Mk21A/W87-1
Abstract
The Mk21A Reentry Vehicle (RV) program will design, develop, produce, and deploy an integrated RV capable of delivering the W87-1 warhead when released from the Sentinel (GBSD) weapon system. The Mk21A program will provide needed performance and security enhancements over the Mk21 RV to meet the upgraded requirements for the Department of Energy (DOE) W87-1 warhead, while ensuring the time certain delivery of both the W87-1 and Mk21A programs. The Mk21A will also meet the requirements laid out in the Sentinel (GBSD) weapon system Capability Development Document (CDD) as directed by Air Force Global Strike Command. The Mk21A RV includes: shape stable nose tip; high impulse transducer; arming and fuzing system (AFS); aeroshell forward section, body section, and rear cover; radio frequency subsystem with antennas; RV spin-up system; in-flight disconnect cable; and other electrical cables. The major activities in the Mk21A RV Technology Maturation and Risk Reduction (TMRR) phase include: (1) Trade Studies, (2) Prototype designs, (3) government systems engineering, analytics, and test capability development, (4) RV risk reduction, and (5) Weapon System (WS) integration risk reduction. During the Engineering and Manufacturing Development (EMD) phase, the Mk21A program will include prime contractor development of a critical RV design, applicable support equipment, data, flight test hardware, infrastructure, and training materials while examining and mitigating weapon system integration risks, nuclear surety, hardness and certification, and system vulnerability assessments. Additionally, the program, in conjunction with the National Nuclear Security Administration, will develop test assets to ensure the integration and qualification of the Mk21A and W87-1 on Sentinel (GBSD) weapon system. This program element may include necessary civilian pay expenses required to manage, execute, and deliver weapon system capability.  The use of such programs funds would be in addition to the civilian pay expenses budgeted in program element 0605827F, 0605828F, 0605829F, 0605831F, 0605832F, 0605833F, 0605898F, 0606398F. In FY2022 $934K was expended for civilian pay expenses in this program element, and in FY2023 $0 is forecasted for civilian pay expenses in this program element.
