ICBM Reentry Vehicles

Abstract

The Intercontinental Ballistic Missile (ICBM) Reentry Vehicles (RVs) activity will design, develop, produce, and deploy integrated RV systems capable of delivering the W87-1 warhead and future warheads when released from the Sentinel (GBSD) weapon system. The Mk21A program will meet the requirements laid out in the Sentinel (GBSD) weapon system Capability Development Document (CDD) as directed by Air Force Global Strike Command, and will provide needed performance and security enhancements over the Mk21 RV to meet the upgraded requirements for the Department of Energy W87-1 warhead. 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 Next Generation Reentry Vehicle (NGRV) program will ensure the Sentinel (GBSD) weapon system continues to meet CDD requirements in an evolving threat landscape by leveraging advanced capabilities matured by the Research & Development (R&D) and ICBM Demonstration/Validation communities in support of the Air Force's Reentry Vehicle Strategy. Future NGRV solutions will integrate with current and/or future warheads and will include acquisition of complementary countermeasures, embracing the modular and adaptable tenets of the 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. 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 the current or subsequent fiscal year.

Document Details

• Document Type: R2 Budgetary Justification
• Publication Date: Oct 01, 2024
• Source ID: 0101328F_7_3600_PB_2024
• Change Summary Explanation: FY22 budget increased from FY23 PB due to a $7.499M reprogramming from ICBM Fuze Modernization (PE 0604933F) to support additional risk reduction activities on the Mk21A TMRR contract. FY23 budget decreased from FY23 PB due to a $3M Congressional Mark citing excess to need. FY24 budget increased from the FY23 PB based on several factors. First Mk21A's recent cost estimates refined the Sentinel integration costs. Specifically, the cost increase is attributed to changes needed to the Payload Reentry System requirements (+$43.4M). Secondly, Mk21A added another fight test due to the anomalous flight test in July 2022 (+$48M). Lastly, NGRV funding was accelerated to begin early acquisition activities in FY 2024 (+$15.5M).
