Due to rogue Pakistan’s and not-so-trustable China’s possession of ballistic missiles, India was forced to initiate a Ballistic Missile Defence (BMD) Programme to protect herself by developing Anti-Ballistic Missiles (ABMs), and after one and a half decade of tiresome research and extensive tests, India developed a Two-tier BMD, a one-of-a-kind in the world which consists of two exo-atmospheric / high altitude interceptor Prithvi Defence Vehicle (PDV), Prithvi Air Defence (PAD) and one endo-atmospheric / low altitude interceptor Advanced Air Defence (AAD) which can destroy incoming ballistic missiles upto 5000km, 2000km away and 200km respectively.
Destroying Pakistani Ballistic Missiles wouldn’t be difficult for Indian ABMs. Most potent missile in Pakistan’s Missile Arsenal is Shaheen II which is basically a Chinese M18, first revealed in 1987 Beijing Air show and Shaheen III is under test which is an improvised Shaheen II and have an extra 250km range than Shaheen II. Chinese M18 is now retired from China’s missile arsenal.
However, the new generation of Ballistic Missiles are more smarter and lethal than before. Such new generation of ballistic missiles have maneuverable thrusters to avoid being destroyed by ABMs, releases Multiple Independently targettable Reentry Vehicles (MIRVs) or simply multiple warheads, decoys to confuse the ABMs, even the warheads are maneuverable and goes by the name of Maneuverable reentry Vehicles (MARVs) and still very accurate (Russian Topol-M ICBM and Chinese DF41 ICBM is such an example). This makes current ABMs extremely difficult to perform its job, which is obviously to destroy the enemy’s ballistic missiles.
So how can India achieve a solid Ballistic Missile Defence?
The idea is quite simple, upgrade the two-tier BMD to four-tier BMD to make sure the warhead never touches Indian soil. Now the question arises what are the two new things included in four-tier BMD? Its none other than much hyped KALI and the new Aditya. Both are Directed Energy Weapons (DEWs) but still different from each other. So now I am gonna explain by portraying a highly possible realistic scene when an enemy fires a sophisticated ballistic missile against India and how these two new weapons and ABMs together can help india achieve a foolproof BMD. Before starting, you must know that a ballistic missile have three phases :-
1. Boost Phase (Ascending)
3. Terminal Phase (Descending)
Scene 1 – The enemy fires a Ballistic Missile with MIRVs targeting several Indian cities.
Scene 2 – Knowing ballistic missiles at Boost Phase travels at an altitude of 300 km or more and thousands of kilometers away towards Indian cities, the BMDs are useless because it can intercept Ballistic Missiles at Terminal Phase i.e. only when the ballistic missiles come down to 150 km altitude or less. The Indian Command Center fires KALI 5000 DEW that emits powerful electron beams as high as 650 km altitude and fries the guidance computer inside the missile, making the missile go haywire or malfunction. But it still doesn’t stops Ballistic Missile Warhead from hitting India.
Scene 3 – As the Ballistic Missile reaches closer to India and gains speed at its mid course, a high altitude interceptor missile (PDV or PAD) is launched. Since the KALI 5000 already fried the computer inside missile, the Ballistic Missile couldn’t perform its evasive functions i.e use thrusters, decoys etc and completely delaying the release of MIRVs, even the MaRVs become as dumb as MIRVs since they are controlled by guidance computers which is fried by KALI 5000, making it easier for the interceptor to hit & destroy the enemy’s incoming missile. If for some reasons the interceptor failed to hit the missile’s payload, but hit the missile’s body instead [ It’s truly difficult to have a pinpoint accuracy i.e. hit missiles’s payload travelling at Mach 20+ ], the payload enters into a free fall.
Scene 4 – As the PDV / PAD destroys ballistic missile’s body…
*Sub situation A – The impact made the missile’s payload enter into a free fall, prompting the missile command centre launch a low altitude interceptor (AAD) to destroy the payload.
*Sub situation B – The impact made the MIRVs inside the payload get separated and enters to a free fall to various Indian cities, prompting the command centre to launch a salvo of AADs to destroy all MIRVs. Let’s just assume here one of the MIRVs slipped past the AAD which is less likely.
Scene 5 – As the last of the MIRVs enters below 20km altitude, the command centre uses the last weapon in the Four-tier BMD which is Aditya Laser DEW to explode the MIRV instantly by heating up the MIRVs skin to several hundred degrees, leading to detonation of explosives inside MIRV’s payload.
In this way, the Four-tier BMD defence can help India protect from even the most advanced Ballistic Missile.
[N.B. – This article is a pure suggestion and explains how Indian BMD can evolve in coming years. There is no Four-tier BMD currently with India nor any plans to induct it. There are some challenges to overcome, if all goes well, India will sure get a Four-tier BMD-like defence by 2020. ABMs, KALI 5000 needs few more tests and if DRDO really does well with a 100 Kilowatts Aditya Laser DEW, things would go very positively.]
