(B) A description of the initiatives of the Secretary of the Navy to ensure that activities key to facilitating the maintenance and modernization of naval vessels (including with respect to increasing workforce and industrial base capability and capacity, shipyard level-loading, and facility improvements) receive sufficient resourcing, and are including in appropriate planning, to facilitate the requirements specified in subparagraph (A). (2) A certification by the Secretary that both the budget for that fiscal year and the future-years defense program submitted to Congress in relation to such budget under section 221 of this title provide for funding for the maintenance and modernization of naval vessels at a level that is sufficient for such maintenance and modernization in accordance with the plan under paragraph (1).
