Arjun Mk2

Maximum level speed. For aircraft this is at optimal altitude; for ground vehicles, top road speed. Higher means faster response and better kinematic performance.

Maximum distance: ferry range for aircraft, operational range for vehicles, maximum engagement distance for missiles. Higher means more standoff or persistence.

Engine power per tonne of vehicle weight. Higher means better acceleration and cross-country mobility.

Primary weapon: main gun, cannon or missile type.

Additional weapons: coaxial MG, remote weapon station, gun pods.

Bore diameter of the main gun or rifle. Larger throws heavier projectiles; not simply better, ammunition commonality matters.

Rounds carried (main gun) or standard magazine capacity.

Armor technology: composite, modular, ERA-fitted, uranium-ceramic. Exact compositions are classified.

Hard-kill APS (Trophy, Arena, Afganit) intercepts incoming projectiles before impact.

Explosive reactive armor (ERA) blocks that disrupt shaped-charge jets.

Sealed crew compartment with overpressure filtration for nuclear/biological/chemical environments.

Overall length including gun/probe where applicable.

Overall width, matters for rail/road transport of vehicles.

Fully loaded weight. Lighter eases transport and bridging limits; heavier often means more armor.

Personnel required to operate. Fewer reduces exposure; autoloaders trade a loader for mechanical complexity.

Powerplant model and type.

Engine output power. Higher moves more weight faster.

Turbofan, turboshaft, diesel, gas turbine, solid-fuel rocket, ramjet…

Bore diameter the round is fired from.

Total production run. Higher means proven manufacturing, mature logistics and spares availability.

Number of countries operating the system. More operators means broader support ecosystem.
