Ground Deployed Advanced Mortar System

Delivering the next generation of close fires for the British Armed Forces.

The UK Ministry of Defence (MOD) requires a close fires solution to boost integral firepower at unit and sub-unit level. Working in collaboration with ST Engineering, we present the 120mm Ground Deployed Advanced Mortar System (GDAMS).

GDAMS is more than just a mortar system; it is a strategic asset designed to meet the British Army’s future operational needs and is primed for export to the UK’s partners. By leveraging its platform-agnostic, modular and highly deployable features, GDAMS positions the UK at the forefront of next-generation, digitally enabled indirect fire systems. Our partnership with ST Engineering also ensures continued innovation through a spiral development roadmap, which includes integrating AI and automation.

In a world of ever-changing uncertainty, it is more critical than ever to provide integrated solutions that deliver unmatched capability, availability and adaptability.

A vehicle mounted GDAMS for every mission

The 120mm GDAMS can be operated by a two-person crew and boasts rapid deployment and stowage times of just 15 seconds, providing unmatched mobility and responsiveness in high-tempo operations. The hinged mortar system is vehicle agnostic, allowing it to be mounted on various vehicles, including in-service platforms such as Jackal, Coyote and Foxhound. The 120mm GDAMS is compatible with a full suite of standard smoothbore munitions: high explosive, illumination, IR illuminated and smoke.  It is capable of precision and extended range (9km) functionality with manual, electronic and smart fuzes, making it the ideal choice for any mission.

The versatility of the 120mm GDAMS is complemented by advanced fire control and targeting systems that enhance accuracy, effectiveness and reduces the time to engage targets. The 120mm GDAMS also offers the patented blast diffuser to drastically reduce noise exposure, increasing stealth and crew safety.

The fully digitalised communication system is both quicker for operators and reduces the risk of human error when manually inputting co-ordinates, leading to a shorter deployment time and more accurate adjustments.  

UK sovereignty at the heart of production

Working with ST Engineering’s world-leading technology, the 120mm GDAMS will be manufactured at our production facility in Devonport, Plymouth. Production will support UK sovereignty by leveraging a British supply chain, including the re-establishment of barrel manufacture in the UK through our partnership with Perfect Bore, who bring exceptional pedigree in barrel manufacture.

Together with building and sustaining a truly UK supply chain; with a successful bid, the 120mm GDAMS production line will also create around 70 new skilled roles at our Devonport facility, as well as additional jobs within the wider supply chain. The new roles will leverage and upskill our existing workforce in Plymouth, as well as offer development opportunities to those who have previously found it difficult to gain employment in the local area through our skills-based work academy programme.

Our state-of-the-art production facility at Devonport sits within the bounds of the South Devon Freeport Zone. With the ability to export at competitive rates due to its Freeport production base, GDAMS offers significant growth potential for UK defence exports, contributing to the nation’s long-term economic and strategic goals whilst simultaneously supporting the UK’s Land Industrial Strategy.

We stand ready to deliver end-to-end solutions

Our strategic partnership with ST Engineering brings together extensive systems integration expertise and cutting-edge land systems technology. Babcock’s close relationship with the British Army and its track record in systems delivery, paired with ST Engineering’s global leadership in mortar technology, ensures that GDAMS is not only tailored for UK defence needs but also competitive on the international market.

We understand the MOD’s priorities, and we stand ready to deliver an end-to-end solution, strengthening defence to meet today’s needs of the British Armed Forces, with innovations to sustain the needs of tomorrow.
