A naval sustainment plan is being implemented to keep the fleet’s final shipboard defensive mounts mission-ready through a coordinated upgrade and overhaul cycle. The initiative ties production support to incremental enhancements, conversions, and maintenance to ensure the last line of ship defense remains available as threats evolve. The compact gun-mount system couples a high-rate-of-fire rotary cannon with radar and electro-optical sensors for search, track, and short-range engagement, and recent iterations added surface-engagement and stabilized imaging capabilities to handle small, low-signature threats. The modernization and sustainment approach stabilizes supply chains and maintenance schedules, so ships retain a reliable protective layer without abrupt platform changes. Effective employment of the system relies on disciplined fire control and accurate sensor-to-shooter loops, because engagement windows are measured in seconds.
