Mk4B Shape Stable Nose Tip
Abstract
The Mk4B (formerly referred to as Mk4A) Shape Stable Nose Tip (SSNT) effort will convert reentry body (RB) forward shell assemblies (FSAs) from legacy carbon composite nose tips to SSNTs. This will require ground and flight testing of SSNT RBs, updates and modifications to RB documentation (Weapon Specifications, Interface Control Drawings, product drawings, etc), updated Fire Control software for fleet implementation, conversion of war reserve RBs to FSAs with SSNT, procurement/conversion of surveillance and flight test units, Strategic Weapons Facility (SWF) logistics implementation planning and execution, and review and updates to both the Mk4B surveillance planning and the DoD share of National Nuclear Security Administration (NNSA) Office of Secure Transportation (OST) for shipping. FY 2023 will be the last year of development for the Mk4B program.
