UK unveils upgraded Challenger 3 tanks amid debate over drone relevance

The upgraded Challenger 3, derived from 1990s Challenger 2 hulls, was presented at a Bedfordshire showcase, highlighting a 120mm gun capable of striking three-mile-distant targets and a new explosive reactive armour that blasts outward when hit. Major Colin Macintyre, a veteran of both Gulf Wars, praised the tank’s survivability, while Major Joseph Murray explained its automatic threat-response system against rockets and grenades.

Critics argue that drones have rendered heavy armour less useful, citing Ukrainian generals’ limited use of tanks and retired US General David Petraeus’s call for drone-only units. The tank lacks built-in anti-drone tools, though RBSL’s Nick Berchem suggested retrofits could be added later. Production of the 148 units, each costing £5.4 million, is slated for next year, but gearbox upgrades could push deliveries to 2029, and training cuts have forced a shift toward simulator-based crew preparation.
