; 10 U.S.C. 7921 note) established the policy of the United States to have available, as soon as practicable, not fewer than 355 battle force ships, with funding subject to the availability of appropriations or other funds. (8) The Department of Defense has been able to achieve program efficiencies and cost savings by using multiyear and block buy contracting with many weapons programs. These contracting strategies are currently being utilized to procure Ford-class aircraft carriers, Arleigh Burke-class destroyers, Virginia-class submarines, and John Lewis-class fleet oilers. 3. Sense of Congress on implementation of the Securing the Homeland by Increasing our Power on the Seas Implementation Act It is the sense of Congress that to achieve the national policy of the United States to have available, as soon as practicable, not fewer than 355 battle force ships— (1) the Navy must be adequately resourced to increase the size of the Navy in accordance with the national policy, which includes the associated ships, aircraft, personnel, sustainment, and munitions; (2) across fiscal years 2021 through 2025, the Navy should start construction on not fewer than— (A) 12 Arleigh Burke-class destroyers; (B) 10 Virginia-class submarines; (C) 2 Columbia-class submarines; (D) 3 San Antonio-class amphibious ships; (E) 1 LHA-class amphibious ship; (F) 6 John Lewis-class fleet oilers; and (G) 5 guided missile frigates; (3) new guided missile frigate construction should increase to a rate of between two and four ships per year once design maturity and construction readiness permit; (4) the Columbia-class submarine program should be funded using the National Sea Based Deterrence Fund with funds that are in addition to the Navy budget in recognition of the critical single national mission that these vessels will perform; (5) stable shipbuilding rates of construction should be maintained for each vessel class, utilizing multi-year or block buy contract authorities when appropriate, until a deliberate transition plan is identified
