United Kingdom In development Rheinmetall BAE Systems Land (RBSL)
Challenger 3
A deep rebuild of the British Army's Challenger 2 hull, replacing the rifled gun with a NATO-standard 120 mm smoothbore and adding a new turret, modern fire control and Trophy active protection. Deliveries to the British Army are planned through the late 2020s.

Availability & export
UK export-licensed
Subject to UK SPIRE licensing (ECJU); generally available to allied states.
Channel: Government-to-government or direct
Fielded & proven
Limited · 1 operator
In service since 2027. Status: announced.
Lifecycle cost (est.)
$25M – $35M
Acquisition is only ~30% of lifecycle cost — operating & support dominate over ~30 yrs. Rough 2.5–3.5× the unit price.
Interoperability
Derived guidance from public data — export regime by country of origin, lifecycle from the GAO ~30% acquisition rule. Verify eligibility, pricing and offsets with the manufacturer and your acquisition authority.
Full specifications
Performance
Speed, range, altitude and engagement capability.
- Max speed
Maximum level speed. For aircraft this is at optimal altitude; for ground vehicles, top road speed. Higher means faster response and better kinematic performance.
- 60 km/h Stronger than 24% of main battle tanks
- Range
Maximum distance: ferry range for aircraft, operational range for vehicles, maximum engagement distance for missiles. Higher means more standoff or persistence.
- 450 km Stronger than 32% of main battle tanks
- Power-to-weight
Engine power per tonne of vehicle weight. Higher means better acceleration and cross-country mobility.
- 19.3 hp/t Stronger than 28% of main battle tanks
Firepower
Armament, payload and guidance.
- Main armament
Primary weapon: main gun, cannon or missile type.
- 120 mm Rheinmetall L/55A1 smoothbore
- Secondary armament
Additional weapons: coaxial MG, remote weapon station, gun pods.
- 7.62 mm coaxial + remote weapon station machine guns
- Caliber
Bore diameter of the main gun or rifle. Larger throws heavier projectiles; not simply better — ammunition commonality matters.
- 120 mm
- Ammunition
Rounds carried (main gun) or standard magazine capacity.
- 40 Stronger than 42% of main battle tanks
Protection
Armor, countermeasures and survivability.
- Armor
Armor technology: composite, modular, ERA-fitted, uranium-ceramic. Exact compositions are classified.
- Composite armor with modular add-on packages
- Active protection
Hard-kill APS (Trophy, Arena, Afganit) intercepts incoming projectiles before impact.
- Trophy
- Reactive armor
Explosive reactive armor (ERA) blocks that disrupt shaped-charge jets.
- No
- Countermeasures
Self-protection: chaff, flares, DIRCM, towed decoys, smoke dischargers, jammers.
- Trophy APS, smoke grenade launchers
- NBC protection
Sealed crew compartment with overpressure filtration for nuclear/biological/chemical environments.
- Yes
Physical
Dimensions, weight and crew.
- Length
Overall length including gun/probe where applicable.
- 8.3 m
- Width
Overall width — matters for rail/road transport of vehicles.
- 3.5 m
- Height
Overall height. Lower profile is harder to spot and hit for ground vehicles.
- 2.5 m
- Combat weight
Fully loaded weight. Lighter eases transport and bridging limits; heavier often means more armor.
- 66,000 kg
- Crew
Personnel required to operate. Fewer reduces exposure; autoloaders trade a loader for mechanical complexity.
- 4
Propulsion
Engine, power and fuel.
- Engine
Powerplant model and type.
- Perkins CV12 diesel
- Engine power
Engine output power. Higher moves more weight faster.
- 1,200 hp Stronger than 53% of main battle tanks
- Propulsion type
Turbofan, turboshaft, diesel, gas turbine, solid-fuel rocket, ramjet…
- Diesel
Sensors & avionics
Radar, sensor suite and datalinks.
- Sensors
IRST, EO/IR turrets, laser designators, sniper pods, thermal sights.
- new-generation fire control system, commander's panoramic sight
- Thermal imaging
Thermal sights for night and obscured-visibility operations.
- Yes
Program
Cost, production scale and operators.
- Unit cost
Approximate flyaway/unit cost where public. Defense pricing varies hugely by contract, offsets and configuration. Lower is cheaper.
- $10,000,000 Stronger than 25% of main battle tanks
- Units built
Total production run. Higher means proven manufacturing, mature logistics and spares availability.
- 0 Bottom 4% of main battle tanks
- Operator countries
Number of countries operating the system. More operators means broader support ecosystem.
- 1 Stronger than 23% of main battle tanks
