BAE Systems to deliver naval guns for Royal Navy’s Type 31 frigates

Defence, security and aerospace company BAE Systems has won a contract to produce and deliver Bofors 40 Mk4 and Bofors 57 Mk3 naval guns for the UK Ministry of Defence’s Type 31 general purpose frigate program.

The agreement, through a contract with Babcock International, will supply the Royal Navy with a set of advanced, multi-purpose gun systems for its fleet of five ships, with the first unit expected to go into service in 2027. 

Specifically, the latest contract with BAE Systems includes five Bofors 57 Mk3 medium caliber guns and 10 Bofors 40 Mk4 small caliber guns. Both close-in weapon systems are designed to protect the ships against modern and future complex threats. The guns also offer the Royal Navy optimized ammunition types, including the cost-efficient programmable Bofors 3P all-target munition.

“We will be providing the … gun system technology … which can adapt to different levels of conflict, including peacekeeping missions, local coastguard operations, and military operations,” Lena Gillström, managing director for BAE Systems Bofors, said.

BAE Systems’ scope of work for the Type 31 program 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 in 2023 and 2024. 

The Bofors 57 Mk3 naval gun is installed on various ship types around the world and is in use with the allied 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.
