The United Kingdom’s L111A1 heavy machine gun is set for a major firepower upgrade after the government awarded a 20-million-pound ($27.3 million) contract to arms maker FN Herstal, part of its broader effort to modernize its frontline weapons and increase firepower.
The decade-long program combines a two-year mid-life improvement initiative with eight years of in-service support, according to the UK Ministry of Defense.
“This upgrade will ensure the weapon system continues to contribute significant firepower across British Army and Royal Navy operations,” it said.
FN Herstal, the UK’s sole manufacturer of military assault rifles and machine guns, will carry out the upgrades at its Kent facility.
Deliveries are scheduled in phases: 18 percent of upgraded machine guns by March 2026, 50 percent by March 2027, and the remaining 32 percent by March 2028.
“Great to mark our continued partnership with the Ministry of Defense in our 50th year of manufacturing in the UK,” the company said, highlighting its long-standing role in supplying Britain’s armed forces.

What is the L11A1 Machine Gun?
The L111A1, an upgraded version of the legendary Browning M2, provides highly versatile firepower. It can be mounted on a tripod for ground operations or fitted to vehicles, giving commanders flexible options for both defensive and offensive engagements.
New features, including a soft mount and quick-change barrel, reduce recoil and improve accuracy, allowing soldiers to engage targets up to 2,000 meters (6,600 feet) away. It weighs roughly 32 kilograms (70 pounds) and fires .50-caliber rounds from a 50-round belt at 485 to 635 rounds per minute.
“This mid-life upgrade will further enhance the lethality of our close combatants,” British Army Head of Military Capability Delivery Nick Serle said.
