The Navy has been procuring Virginia SSN-774 class nuclear-powered attack submarines since FY1998. The two Virginia-class boats requested for procurement in FY2017 are to be the 25th and 26th boats in the class. The 10 Virginia-class boats programmed for procurement in FY2014-FY2018 two per year for five years are being procured under a multiyear-procurement MYP contract.The Navy estimates the combined procurement cost of the two Virginia-class boats requested for procurement in FY2017 at 5,408.9 million, or an average of 2,704.5 million each. The boats have received a total of 1,623.3 million in prior-year advance procurement AP funding and 597.6 million in prior-year Economic Order Quantity EOQ funding. The Navys proposed FY2017 budget requests the remaining 3,188.0 million needed to complete the boats estimated combined procurement cost. The Navys proposed FY2017 budget also requests 1,767.2 million in AP funding for Virginia-class boats to be procured in future fiscal years, bringing the total FY2017 funding request for the program excluding outfitting and post-delivery costs to 4,955.2 million.The Navys proposed FY2017 budget also requests 97.9 million in research and development funding for the Virginia Payload Module VPM. The funding is contained in Program Element PE 0604580N, entitled Virginia Payload Module VPM, which is line 128 in the Navys FY2017 research and development account.The Navy plans to build some of the Virginia-class boats procured in FY2019 and subsequent years with an additional mid-body section, called the Virginia Payload Module VPM, that contains four large-diameter, vertical launch tubes that the boats would use to store and fire additional Tomahawk cruise missiles or other payloads, such as large-diameter unmanned underwater vehicles UUVs.The Navys FY2016 30-year SSN procurement plan, if implemented, would not be sufficient to maintain a force of 48 SSNs consistently over the long run.
