In a written parliamentary answer to Conservative MP Ben Obese-Jecty, defence minister Luke Pollard said the UK joined the Common Armoured Vehicle System research and development programme in December 2025. He stated that the initiative is “a multinational programme with Finland, centred around the Patria 6×6 armoured vehicle” and confirmed that “the programme is in the assessment phase”.
The Common Armoured Vehicle System programme was launched in 2020 by Finland, Estonia and Latvia to develop a shared 6×6 armoured platform, with additional European nations joining since. Sweden and Germany entered the programme in 2022, with Germany becoming a full procurement member in January 2025. Norway and the UK joined the initiative in September 2025.
The Patria 6×6, also known as the XA-300, is a wheeled armoured personnel carrier designed primarily for troop transport but configurable for a range of roles. According to the manufacturer, the platform can be fitted with optional features including amphibious capability, enhanced armour packages and a variety of weapon systems ranging from machine guns to medium-calibre turrets and a 120mm turreted mortar.
In January 2025, Babcock UK and Patria signed a memorandum of understanding aimed at supporting a potential UK Army requirement for the vehicle, signalling early industrial alignment should the programme progress. No contract has been placed, and the MOD has not confirmed fleet size, role or timelines.
The Patria 6×6 has already been ordered by several CAVS members. Latvia has procured more than 200 vehicles, with deliveries beginning in 2021, while Sweden has ordered a total of 425 vehicles under the designation Pansarterrängbil 300, with deliveries planned through to 2030. Finland has also signalled intent to acquire 160 vehicles, following delivery of pre-series platforms for testing.
