At the designated nanosecond, the interceptor missile roared out of its canister, engulfing the Lahav's deck in a ball of fire. Quickly gaining supersonic speed, it levelled out and streaked towards the incoming missile, guided by continuous target updates transmitted by the MF-STAR over a data link.
Seven kilometres short of the target, a seeker on-board the missile switched on; now the missile was itself locked onto the target, tracking its manoeuvres.
The dual-pulse motor fired again, accelerating the missile that was, by now, merely "coasting". This increased velocity allowed the missile to manoeuvre sharply, keeping up with the target's evasive zigzags - termed "target dynamics".
As the interceptor arrived a few metres from the target, a proximity fuse detonated its 23-kilo high-explosive warhead. This aims to destroy the target or damage it enough to prevent it reaching the mother warship. In Thursday's test, the Israelis claim the proximity fuse was irrelevant, since the
interceptor missile directly hit the simulated target. "It was metal on metal," says an Israeli source.

DRDO sources describe working with the Israelis in developing the LR-SAM as "a lesson in professionalism and capable project management". The LR-SAM, which was to be operationalised in October 2012, is running three years late, but DRDO admits this is
because of Indian delays in developing the dual-pulse motors, which required developing an entirely new propellant.
