BAE Systems Integrates Mk 45 Gun on HMS Glasgow in 2024

BAE Systems has initiated the integration of the Mk 45 naval gun system onto HMS Glasgow, marking a significant milestone in the development of the U.K. Royal Navy's Type 26 frigates. This installation is the first of eight planned for the class, which aims to enhance the firepower and operational readiness of these advanced vessels. The Mk 45 system features a 5-inch, 62-caliber gun paired with a fully automated Ammunition Handling System (AHS), designed to improve safety and efficiency during operations. The AHS is capable of automatically reloading the Mk 45 gun in various sea conditions, thereby reducing the need for extensive crew involvement and ensuring reliable performance. This technological advancement is expected to streamline operations and enhance the overall effectiveness of the Royal Navy's fleet. The contract for this integration, valued at $219 million, was awarded to BAE Systems in February 2023, underscoring the commitment to modernizing the naval capabilities of the U.K. In addition to the U.K. Royal Navy, the Mk 45 system has also been selected for the Australian Navy's Hunter Class frigates, which are based on the same design as the Type 26. This indicates a growing international interest in the capabilities offered by the Mk 45 and AHS, further solidifying BAE Systems' position in the global defense market. Engineering and program support for this initiative is being conducted at BAE Systems' facility in Minneapolis, Minnesota, while production takes place in Louisville, Kentucky. The successful integration of the Mk 45 on HMS Glasgow is expected to set a strong foundation for future installations across the Type 26 class, enhancing the Royal Navy's operational capabilities.
