BAE System to Provide Mk 45 Naval Guns for Aussie Hunter Frigates

BAE Systems has secured a contract to supply the Royal Australian Navy's new Hunter class frigates with multiple sets of the Mk 45 Medium Caliber Gun and automated Ammunition Handling System (AHS).

The Mk 45-gun system comprises the 5-inch, 62-caliber Mk 45 Mod 4A naval gun, paired with a fully automated AHS.

This system ensures continuous ammunition supply to the gun, even in challenging high sea state conditions, eliminating the need for crew assistance. The automated gun system not only enhances Sailor productivity but also mitigates risks to Sailor safety, thereby bolstering the operational capability of the Mk 45 at sea.

The contract activities are scheduled to commence in 2023 and conclude in 2036. Engineering tasks will be carried out in Minneapolis, Minnesota, while production will take place in Louisville, Kentucky.
