> UK's 16x shell-output expansion runs months behind; capacity target doubled after a mid-2025 rethink

## Summary

[Bae Systems](/en/entity/bae-systems)' new explosive-filling plant at Glascoed in South Wales — pitched as a
16-fold increase in [United Kingdom](/en/entity/united-kingdom) 155mm shell output — is running roughly six months
behind schedule. BAE attributes the slip to a mid-2025 decision to double the plant's
originally planned capacity; testing is under way with no revised launch date. The site
targets ~500,000 shells a year and sits inside a £150m UK production-expansion programme and
the £2.4bn Next Generation Munitions Solution framework, recently widened by the MoD toward
£410m. The delay matters for British Army stockpile rebuilds and continued resupply to
[Ukraine](/en/entity/ukraine); it contrasts with [Rheinmetall](/en/entity/rheinmetall)'s faster German ramp — see
[Rheinmetall says Germany has overtaken the US in conventional ammunition output](/en/n/germany-ammunition-overtakes-us-2026) and Shell Production.

## By the numbers

- 16x — planned 155mm output increase at Glascoed.
- ~6 months — reported schedule slip.
- ~500,000/yr — targeted shell output once running.
- £150m — UK munitions production-expansion programme.
- £410m — expanded MoD munitions contract value.
- 1,260 — BAE staff across five UK munitions sites.

## Why it matters

Glascoed is Britain's single biggest bet on artillery throughput. A multi-month slip leaves
the UK reliant on imports and continental lines just as Europe scales, exposing how hard
greenfield explosives capacity is to stand up at speed.

## What to watch

- A revised Glascoed commissioning date.
- Whether doubled capacity (toward ~1m/yr equivalents) is confirmed.
- Further MoD call-offs against the NGMS framework.
