Anzac-class frigates to receive naval gun upgrades

BAE Systems has been awarded a contract by the Commonwealth of Australia to upgrade existing Mk 45 Mod 2 naval gun systems on Anzac-class frigates with a Common Control System (CCS).

The upgrade modifies existing Mk 45 systems to eliminate obsolescence issues and extend the life of the gun system.

The CCS upgrade replaces electronics on earlier Mk 45 Mod 1 and Mod 2 gun systems to be compatible with the Mk 45 Mod 4, the latest configuration used by the US Navy. In addition to delivering commonality and interoperability with the US Navy’s gun systems, the upgrade will equip the Mk 45s with the capability to integrate future extended-range precision guided munitions, such as the hypervelocity projectile.

Work on the contract will take place at the BAE Systems production facility in Louisville, Kentucky with the first delivery planned in early 2026.
