Submarine Launched Ballistic Missile (SLBM). Early FYDP efforts will primarily consist of developing programmatic planning and structure to support the continuing
study and future program along with further exploration and refinement of the concept studies that resulted from the FY19 Navy Feasibility Study. Programmatic efforts
will consist of program planning and development of cross-agency plans (risk and opportunity, decision documentation and communication). Following the results of the
Navy Feasibility Study, refinement of the concept study will be accomplished through system trade studies and drafting initial high level requirements documents in order
to support the program entering a Phase 2 (Feasibility Study and Design Options) / 2A (Design Definition and Cost Study) effort in FY24.
In FY21, the project will further refine the down-selected concepts, screening criteria and programmatic tradeoffs (e.g., cost, schedule, technical maturity) for the
concepts being considered. Additionally FY21 will begin aeroshell development efforts to include developing the materials and infrastructure necessary to support a
mass mock flight experiment shortly after Phase 3 (Engineering Development) authorization.
The Integrated Nuclear Weapons Security System (INWSS) (3158) efforts support the Nuclear Weapons Security program and SSBN Escort mission. The policies and
requirements regarding the safeguard of nuclear weapons within the Department of Defense is established by DoD S5210.41M. Within the Department of the Navy,
nuclear weapons are limited to TRIDENT Fleet Ballistic Missiles (FBM), either deployed aboard TRIDENT submarines or located landside at Naval Submarine Base,
Kings Bay, or Naval Submarine Base, Bangor where missiles are first assembled as well as repaired. The Chief of Naval Operations (CNO) has assigned the Strategic
Systems Programs (SSP), the FBM program manager, with mission responsibility for the safeguard of FBM nuclear technologies. This budget supports efforts directed
at improving the current technological baseline through a series of studies. These efforts will improve countermeasure technologies to address detection, delay and
denial.
