The US Navy (USN) is requesting about USD11 billion for submarine acquisition and research and development (R&D) for fiscal year 2019 (FY 2019).
The FY 2019 request includes about USD7.3 billion for Virginia-class fast-attack submarines and USD3.7 billion for Columbia-class vessels, which are slated to replace Ohio-class strategic-missile submarines (SSBNs).
The budget request includes about USD7.2 billion for two Block V Virginia-class submarines and related advance procurement and economic order quantity funds, which are part of the FY 2019-23 multiyear procurement plan.
The Block V hulls, USN documents said, will include improvements in acoustic stealth and on-hull sensors. The second hull in FY 2019 will include the first Virginia Payload Module, a hull section with four additional payload tubes capable of carrying an additional 28 Tomahawk cruise missiles, which increases the Tomahawk per-ship capacity to 40 from 12.
