AMS

What AMS does

AMS is a privately-held defence support services provider, founded in 2001 and headquartered in Exeter, UK with operational offices in Dubai (UAE free zones) and Florida. The company delivers four integrated service lines to ministries of defence and international organisations globally: Maintenance, Repair & Overhaul (MRO) for military land systems; Field Support Representatives (FSR) providing frontline technical assistance embedded with armed forces; Technical Training Services for operators and maintainers; and Supply Chain Services covering spare parts procurement, defence vehicle procurement, and end-to-end logistics. Underlying technology includes the proprietary FASTrax supply chain management platform and digitally enhanced asset oversight tooling supporting predictive maintenance.

The company generates revenue primarily through long-term managed service contracts with government customers — including UK MOD, US DoD, UAE Armed Forces, Ukrainian MOD, Algerian Military, and UN/NATO missions — supplemented by professional services for training and transaction-fee supply chain work. Distribution is direct-to-government via tender processes, with strategic OEM partnerships (Navistar Defense, BAE Systems, Pearson Engineering, Roke Manor Research) providing channel and teaming access. Operational scale is significant for a privately-held SME, with a claimed footprint across 60+ countries, 1,100+ active suppliers, and programmes managing up to 130,000+ vehicles. In 2026, AMS was acquired by Calian Group Ltd. as part of Calian's defence services expansion strategy.

Core offering

AMS provides maintenance, repair, and overhaul (MRO) services for military land systems and equipment operated by government defence forces. Its offering spans four integrated service lines: depot and field-level MRO, Field Support Representatives deployed to customer sites, bespoke technical training for military personnel, and end-to-end supply chain services covering spare parts, defence systems, and vehicle procurement, supported by the proprietary FASTrax system.

Product overview

AMS provides defence support services as a single unified offering centred on Maintenance, Repair & Overhaul (MRO) for military land systems and equipment. The company's portfolio consists of four integrated core service lines: MRO (depot and field-level maintenance, repair, overhaul, and modernisation programmes), Field Support Representatives (FSR) providing frontline on-site technical assistance, Technical Training Services (operator and maintenance training), and Supply Chain Services (sourcing, procurement, and logistics). These services are designed to work together to ensure military equipment remains mission-ready, with the supply chain operations supporting MRO activities through spare parts and materials procurement, and FSRs providing immediate field-level support while training programmes develop workforce competencies.
