Proof and Experimental Establishment (PXE) conducts instrumented design and developmental trials of armament stores, i.e., weapons, ammunition and their components by dynamic firing;. Ballistic evaluation of armour materials.; Technical evaluation of imported weapons and ammunition;. Carries out various out-turn proof of weapons, ammunition and their components and armour produced by Ordnance Factories, PSUs and trade firms. PXE also undertakes periodical depot check proof; investigation firing for failure analysis; undertake range specific projects/ tasks in aid of supporting test and evaluation. Analysis of ballistic data and design parameters. Modelling and simulation of the ballistic impact of armour. Radar cross-section (RCS) and radar absorbing material (RAM) performance simulation facility.
