The U.S. Navy’s Portfolio Acquisition Executive (PAE) Strategic Systems Programs’ (SSP) W93 Mk7 program has entered into the Engineering and Manufacturing Development (EMD) phase of the Defense Acquisition System after achieving Milestone B this year. During the EMD phase, the program will focus on completing production design and proving that the design is producible to meet the needs of the Navy. The W93 warhead and the Mk7 reentry body assembly are the first United States nuclear warhead and reentry system program initiated in nearly four decades and will provide a modern warhead to the U.S. submarine launched ballistic missile fleet. ... Looking to the future, PAE SSP is actively modernizing the sea-based leg of the nuclear triad through the development of the D5LE2 strategic weapon system and pioneering regional strike capabilities of the future through development of SLCM-N and the non-nuclear hypersonic conventional prompt strike system. https://www.ssp.navy.mil/News-Media/News/Article/4610170/navy-w93-mk7-program-enters-new-phase-of-development/
