UK MOD DE&S Issues £20m 9mm Ball NATO Ammunition Competition Through Defence General Munitions Project Team

Technical Summary

The UK Ministry of Defence (MOD), acting through Defence Equipment and Support (DE&S) and its Defence General Munitions (DGM) Project Team, has issued a competitive procurement notice for 9mm Ball NATO and 9mm Drill ammunition under Find a Tender Service notice 011363-2026. The estimated value is £20,000,000 excluding VAT (£22,000,000 inclusive of VAT). The contract is structured as a five-year base period with three additional one-year option periods, providing a maximum eight-year supply window with break clauses. Tender deadline as published was 13 March 2026, placing the award decision squarely in the second quarter of 2026 with first deliveries expected against the FY2026/27 ammunition replenishment cycle.

The procurement falls within the 9 × 19 mm Parabellum NATO standard, governed by NATO STANAG 4090 (NATO Standardisation Agreement — 9mm Parabellum NATO Ball Cartridge), and meeting the dimensional, ballistic and pressure parameters defined under STANAG 4090 Annex A. The Drill component, used for weapon-handling training across the UK Armed Forces and the Defence School of Police and Guarding, is a fully inert variant manufactured under STANAG 4090 dimensional control without primer, propellant or projectile core. The cartridge family is the standard sidearm round for the Glock 17 Gen 4 (in service with the British Army and the Royal Navy) and the Heckler & Koch MP5 (in service with specialist policing and Royal Marines roles).

£20 million for 9mm Ball NATO and Drill ammunition over a five-year base term with three option years — the eight-year addressable value sits at approximately the £32 million mark and signals an annual replenishment rhythm that would equate to around eight to ten million ball rounds per contract year on benchmarked unit pricing.

Analysis of Effects

9mm Ball NATO is a Full Metal Jacket (FMJ) projectile of nominal mass 7.5 g (124 grain) propelled to a STANAG 4090-specified muzzle velocity of approximately 360 m/s from a 117 mm barrel. Muzzle energy at this velocity is approximately 490 J. The propellant charge is a double-base nitrocellulose / nitroglycerine smokeless powder of approximately 0.4 g per round; the primer is a Boxer-pattern percussion primer charged with either lead styphnate or lead-free Sintox/SynTech equivalents to meet the contemporary green-ammunition policy lines published under DSA 03.OME Part 5 and the underlying Health and Safety Executive (HSE) lead-exposure limits.

The hazard classification for the cartridge as packaged is Hazard Division 1.4, Compatibility Group S (HD 1.4S) under the UN Recommendations on the Transport of Dangerous Goods (Model Regulations) and STANAG 4123, with the NATO Ammunition Safety Group (NASG) applying the Assembly Rule at the cartridge level. NEQ per round is dominated by the propellant charge at ~0.4 g; aggregate NEQ for a single 25-round palletised case (the standard UK MOD shipping unit) is approximately 0.4 g × 25 = 10 g, and for a 1,000-round bulk pack approximately 0.4 kg. Stockpile-level NEQ for a typical year’s contract obligation, based on benchmarked £0.50–£0.65 per round and the £20m / five-year envelope, lies in the range of approximately 12–16 tonnes of propellant net explosive content distributed across the order — modest, but operationally significant for storage planning at depot level.

Personnel and Safety Considerations

For ammunition technicians (Royal Logistic Corps Ammunition Technicians, RAF Armament Technicians, Royal Naval Armament Supply staff) the 9mm Ball cartridge is an HD 1.4S commodity with the simplest possible storage profile under DSA 03.OME Part 2 and the underlying explosive licensing regime issued by the Defence Land Range Safety (DLRS) and the Defence Ordnance Safety Group (DOSG). The specific stockpile arithmetic of interest is the proximity rule for HD 1.4S items co-located with HD 1.1 stocks: HD 1.4S contributes only its mass to the NEQ summation only insofar as packaging and Compatibility Group rules permit (S indicates the item is so insensitive that no significant external hazard is presented in normal storage), and STANAG 4439 / AOP-39 insensitive-munitions logic does not apply as cartridge ammunition does not enter the IM regime.

The lead-styphnate-versus-Sintox decision is operationally consequential. Indoor ranges — including the Joint Service Indoor Marksmanship Trainer (DCCT) and unit ranges at Bisley, Catterick, Pirbright and Lympstone — have moved progressively to lead-free primers since the 2018 HSE Workplace Exposure Limit revision; the DGM tender specification is expected to require Sintox or equivalent lead-free chemistry. The Drill ammunition variant carries no propellant and no primer and presents no explosive hazard in storage, though it does still fall under UK Firearms Act 1968 Section 57 controls owing to dimensional similarity to the live round. UK MOD policy continues to colour-code Drill rounds in accordance with JSP 482 / DSA 03.OME marking conventions.

Data Gaps

DATA GAP: Quantity per year — the FAT notice does not publish the per-year ball-round and drill-round quantity, only the aggregate £20m envelope. Implied unit-volume estimates depend on the awarded unit price.

DATA GAP: Bidder shortlist — competitive bidders are not yet disclosed. Likely bidders include Swiss P (incumbent under DGM/1911), CBC Brazil, Manroy / Federal, MEN Germany, FN Herstal, Sellier & Bellot and Olin Winchester.

DATA GAP: Lot structure — the FAT notice does not confirm whether the requirement is divided into Ball and Drill lots or awarded as a single combined contract, which materially affects the small-bidder participation profile.

DATA GAP: Sovereign-supply weighting — whether the evaluation criteria include a UK-content or Defence and Security Industrial Strategy (DSIS) weighting in line with the SDR 2025 sovereign munitions pipeline policy is not stated in the public notice.
