Challenger 2
WesternFV4034 Challenger 2
The Challenger 2 is the British Army's main battle tank, produced by Vickers Defence Systems (now BAE Systems). It features unique Chobham 2 (Dorchester) composite armor — considered the strongest passive armor of any NATO tank — a 120mm L30A1 rifled gun, and a stabilised thermal imaging fire control system. The UK pledged 14 Challenger 2 tanks to Ukraine in January 2023 as the first Western MBT commitment.

✓ Strengths
- •Exceptionally strong Dorchester composite armor — resistant to most HEAT warheads
- •Rifled gun fires both APFSDS and HESH — versatile against different targets
- •Outstanding crew protection record historically
- •Excellent fire control system — high first-shot hit probability
⚠ Limitations
- •Heaviest operational Western MBT at 62.5t — bridge weight limits apply
- •Diesel-powered (not gas turbine) — lower maintenance demands than Abrams
- •Only 14 supplied — too few for decisive operational impact
- •Unique rifled ammunition — can't use standard NATO 120mm rounds
Notable Use
In September 2023 one Challenger 2 was destroyed during Ukraine's counteroffensive — the first recorded combat loss of a Challenger 2 in the tank's operational history. The UK subsequently supplied additional CR2 tanks and ammunition, with a total pledge of 14 tanks.
Ukraine War Context
The UK's Challenger 2 pledge in January 2023 was a diplomatic breakthrough that encouraged Germany and the US to approve their Leopard 2 and M1 Abrams shipments. Ukraine deployed the small fleet in the Zaporizhzhia counteroffensive sector. The unique British HESH and APFSDS ammunition required a dedicated supply chain.
