BAE Systems’ Naval Guns for RN Type 31 Frigates

Five Bofors 57 Mk3 and 10 Bofors 40 Mk4

Under a contract with Babcock International, BAE Systems is to supply five Bofors 57 Mk3 and 10 Bofors 40 Mk4 gun systems for the Royal Navy’s (RN) Type 31 general-purpose frigate programme, with the first of the five contracted vessels expected to enter service in 2027.

Both close-in weapon systems are designed to protect the ships against modern and future complex threats. They also offer the RN optimised ammunition types, including the cost-efficient and programmable Bofors 3P all-target munition.

We will be providing the most cutting-edge gun system technology available, which can adapt to different levels of conflict, including peacekeeping missions, local coastguard operations, and military operations,” explained Lena Gillström, Managing Director for BAE Systems Bofors. “This contract increases the number of European nations deploying our advanced, flexible weapon systems.”

BAE Systems’ scope of work for the Type 31 programme also includes services, tools, spares, documentation and support. Both naval gun systems will be manufactured at BAE Systems’ facility in Karlskoga, Sweden, with deliveries expected to take place 2023-2024.  

The Bofors 57 Mk3 naval gun is installed on several ship types globally, and is in use with the navies and coast guards of eight nations, including Canada, Finland, Germany, and Sweden, as well as the United States, where it is known as the Mk110 naval gun. BAE Systems has built and delivered more than 100 Bofors 57 Mk3 naval guns to customers around the world. The Bofors 40 Mk4 naval gun is the latest generation in the 40mm family, and with this contract , the RN becomes its fifth operator.
