USNI – The Aegis ballistic missile defense (BMD) program, which is carried out by the Missile Defense Agency (MDA) and the Navy, gives Navy Aegis cruisers and destroyers a capability for conducting BMD operations. The Department of Defense’s January 2019 missile defense review report states that the number of operational BMD-capable Aegis ships was 38 at the end of FY2018 and is planned to increase to 60 by the end of FY2023.
The Aegis BMD program is funded mostly through MDA’s budget. The Navy’s budget provides additional funding for BMD-related efforts. MDA’s proposed FY2019 budget requests a total of
$1,711.8 million in procurement and research and development funding for Aegis BMD efforts, including funding for two Aegis Ashore sites in Poland and Romania that are to be part of the European Phased Adaptive Approach (EPAA). MDA’s budget also includes operations and maintenance (O&M) and military construction (MilCon) funding for the Aegis BMD program.
