GROUND BASED STRATEGIC DETERRENT (GBSD)
Abstract
The Ground Based Strategic Deterrent (GBSD) will design, develop, produce and deploy a replacement for the current Intercontinental Ballistic Missile (ICBM) Minuteman III (MM III) weapon system. The GBSD program is scoped to deliver a fully integrated weapon system beginning in FY29 timeframe to close key capability gaps and vulnerabilities identified in the GBSD Capabilities Based Assessment, GBSD Initial Capabilities Document, and the GBSD Analysis of Alternatives; and to mitigate ground-based deterrent degradation due to MM III component age-out and attrition. The GBSD program will include Prime contractor development of applicable support equipment, data, flight test hardware and infrastructure, and training material while examining and mitigating risk during the MM III to GBSD transition. This program includes any needed nuclear surety and certification and system vulnerability assessments. The major activities in the GBSD program include 1) Government system engineering (SE), analytics, and test capability development; 2) Flight System (FS) Risk Reduction; 3) Weapon System Command and Control (WSC2) Risk Reduction; 4) Launch Systems (LS) Risk Reduction; 5) Weapon System Integration (WSI) Risk Reduction. Government SE investments include development of an organic, computer-aided, model based systems engineering (MBSE), integration, test software, product life-cycle management (PLM) framework, and modernization of existing SE labs and infrastructure. FS is an integrated missile stack which includes the propulsion, post-boost, guidance, and re-entry systems (RS) sub-components. WSC2 encompasses all command and control components and interfaces, associated ground hardware, ground control equipment and associated software directly related to the survivability, monitoring and launch of the replacement flight system. LS include Launch Control Center (LCC), Launch Facility (LF) restoration, modernization of real property and structures and associated ground mechanical systems. WSI risk reduction includes non-proprietary open systems architecture with well defined interfaces and a modular design at the weapon system level to allow future modification and technology insertion. This program element may include necessary civilian pay expenses required to manage, execute, and deliver GBSD 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. BA4 - This program is in Budget Activity 4, Advanced Component Development and Prototypes (ACD&P) because efforts are necessary to evaluate integrated technologies, representative modes or prototype systems in a high fidelity and realistic operating environment.
