2.Active Protection System (for Arjun) Warhead Based on EXPLOSIVELY FORMED PROJECTILE (EFP)

( From the paper by Sarbjit Singh, TBRL, Chandigarh, dss 2010)


In short, this warhead works like a shotgun shell , forming a circle of 6-7 jets of molten metal travelling @ mach 6, destroying the incoming ATGM.





DETAILS:


TBRL have developed a multi EFP based warhead for APS. Such a warhead with suitable detection system mounted on MBTs, command control bunkers and important installations provides protection from antitank rockets/missiles including
top-attack Anti-Tank Guided Missile (ATGM).

The detection system incorporates the solutions for use of multi-functional millimeter radar with “instant” scanning of all protected sector to detect and track antitank targets.

Protective ammunition is housed in silo sections arranged around the turret.


A systematic study for development of multi EFP based warhead capable of destroying incoming Anti-Tank Guided Missile (ATGM) at a safe distance of 20-30m from the intended target has been carried out.

A warhead of 190mm diameter has been designed using 7 numbersof liners of 45 mm diameter.

All seven liners were formed into EFPs which perforated 10mm mild steel target plate kept at 5 m distance. A total number of seven holes were recorded on the target within 550mm scatter.

Thank you for photos. Are they can be used for AIP?

I think they can but more improvement may be needed for submarine operation. The block on the truck has 30kW power. German U-212 (U31) is powered by 9 HDW/Siemens PEM fuel cells with 30 kW each. So may be it can.

Hey Kinetic sir,any news about the AESA based MPR ? Is it ready for testing??

As far as I know from various news sources and DRDO websites, the MPR prototype is ready and trial will start soon or already started.
