The billion dollar question arises just after the launch. According to some folks , the TVC vanes are jettisoned just after the missile has been vectored to its required heading .

Some other folks say the TVC arrangement that is the vanes remain with the missile throughout its envelope .

I am still looking up on this .

Astra mk2 design is similar to Barak-8.

Why Do We Need 'Israeli's UHF & VHF radars ??

Swordfish is an advanced L-band active phased array radar developed by the Defence Research and Development Organization (DRDO). Unlike the most radars used by Indian forces, the Swordfish is capable of successfully detect, track and stop inbound ballistic missile threats. The radar was specifically built with Israeli assistance to meet the demands of a fledgling Indian Ballistic Missle Defence (BMD) system. The main reason for the high altitude requirement was to ensure that the inbound threat could be eliminated in outer space by exoatmospheric interceptors.

Swordfish has proven itself in over 10 successful missile interceptions including two* exo-atmospheric hit-to-kill (H2K) interception. The existing variant of radar has a range of 600-800 km and can detect targets as small as cricket ball at a long distance. The maximum target speeds up to which it can be tracked by Swordfish is over Mach 12.
In the fully automated, multi-layer mode, a single battery of BMD system could engage 6 high-speed ballistic targets with up to 98% kill probability (when 2 exo-interceptors are launched simultaneously and 2 endo-atmospheric interceptors are in standby mode). All Pakistani ballistic are well within the engagement envelope of the BMD system. But something has changed- Ababeel MIRV-capable missile.
Pakistan first announced its test of the MIRVed missile on 24th January 2017. However, during the test firing of the missile, it was not carrying any MIRVs and it would be years before the missile is operational. Ababeel has a range of 2000 km and it can carry at least 3 MIRVs. While the missile is still well within the engagement envelope of Indian BMD, smaller warheads are likely to be troublesome.
Why?

MIRV warheads are very small, and the shape itself makes RVs inherently low observable from all direction. Frontal RCS can be smaller than that of a golf ball. Low RCS can drastically reduce the probability of detection and thereby delay the launch sequence - the result is reduced kill probability.

Super-Swordfish cometh
Super-Swordfish radar was first unveiled in 2012, it was stated to be twice as powerful as older swordfish radar. The new radar has a range of over 1500km, facilitating early detection of inbound threats. if reports are to be believed, Super-Swordfish is already operational.
The interesting fact is that the development of Super-Swordfish probably started after Pakistan started working on a MIRVed missile. According to National Interest, 'The BBC reported back in 2010 that Pakistani missile designers were receiving substantial assistance from China in developing MIRV technology. The Ababeel appears to have a large nose cone, which may allow it to carry multiple warheads even if they are slightly larger than normal MIRVed warheads.'

Even though Pakistan tested Ababeel in 2017, India had already begun consolidating missile defence. Older RF guidance based Prithvi Interceptor missile has been replaced by much improved Prithvi Defence Vehicle (similar to THAAD). The new interceptors can intercept RVs at altitudes above 150 km. Since PDV is guided by an IIR seeker it can easily detect RV at a long distance thanks to a high-temperature differential between RV and cold space. On paper, PDV is superior to S-400's 40N6 missile, owing to its superior guidance and hit-to-kill target engagement mechanism.

Can Ababeel be intercepted?
The reentry speed of Ababeel's RVs is well within the interception envelope of PDV and AAD. Any High-Value Asset (HVA) is likely to be protected by multiple BMD missile batteries. Given the weak economic state of Pakistan, there won't be overwhelming numbers of this type of expansive missiles and Indian BMD will be continuously updated to counter new threats.

AD-1/AD-2 interceptors for a midcourse interception

A possible new addition to BMD early warning system

“A single early-warning satellite, giving you constant, complete coverage of the country, is unique,” according to Dr V.Jayaraman, former Director at ISRO’s Hyderabad-based National Remote Sensing Centre.

*In the first exoatmospheric flight PDV didn't have any target.

Any idea whether India plans mid course interception.. Can AD-1 and AD-2 double up as mid course interception missiles for 2000 km range missiles, while doing terminal phase interception for 5000 km range missiles.. Or do we have a new class of mod course interception missiles under development?

Its Well known that Mid course Interception program covered by PAD Which upgraded to PDV 1 And PDV 2

Its Divided in Two stage


hit-to-kill (HTK) interception achieved by the Defence Research & Development Organization’s (DRDO’s) updated exo-atmospheric ‘PDV’ anti-ballistic missile (ABM) interceptor on February 11, 2017, was a watershed moment in the history of India’s ballistic missile defence (BMD) program. The exo-atmospheric intercept achieved at an altitude of 97 km validated among other things, the improved guidance algorithm used for this test-mission, since the incoming missile target had deviated significantly from what would have allowed an intercept along a typical minimum energy trajectory (MET) for an ABM interceptor. Instead, the PDV test-vehicle had to slam into the target at the far end of its engagement boundary and at a lower altitude than what a ‘standard’ MET intercept would have entailed.

An intercept of this nature may also be indicative of the maturity of the on-board imaging infrared seeker (IIR), the responsiveness of the divert and attitude control system (DACS) used by the PDV’s kinetic kill vehicle (KKV), as well as the sensor fusion achieved by various tracking systems involved in the mission.



A closer look at PDV

PDV serves as an exo-atmospheric interceptor for India’s emerging two-tier ballistic missile defence (BMD) system consisting of both endo and exo atmospheric interception capability. DRDO first tested PDV in 2014 (see the embedded video) in a mission that was essentially used to validate the ABM interceptor’s integration with the detection, tracking and automated launch control systems associated with the two-tier BMD scheme and no actual intercept was attempted that time over. This latest test however was used to prove the KKV used by PDV by destroying an actual incoming warhead in a HTK mission.


Now, PDV replaces the PAD ABM interceptor, which was first tested in 2006, as the kill vector in the high-altitude interception leg of the two-tier system conceived under Phase-I of India’s BMD programme. However, while PAD was essentially a high endo-atmospheric system with a ceiling of around 85 km, PDV is a true blue exo-atmospheric interceptor capable of destroying targets at altitudes of up to 150 km. This puts PDV in a different category in terms of its navigation set-up and homing seeker capability. Instead of sporting a radio frequency (RF) seeker like PAD, PDV uses a strap-down IIR seeker developed by DRDO’s Research Centre Imarat (RCI) with a 128 x 128 focal plane array.

Left unsaid in this latest BMD test by DRDO is the clear demonstration of the low earth orbit (LEO) capabilities of PDV. PDV is actually a predecessor to another exo-atmospheric interceptor currently under development that can neutralize RVs at altitudes of over 300 km. Taken together this means that India has all the elements in place for a direct ascent counter space system that can potentially be used for anti-satellite purposes. This in turn means that India now has a very strong hand in the Space NPT that is currently being quietly negotiated by the world’s nuclear powers.



Stage Two



The weapon system
For a successful ASAT demonstration, scientists from the Defence Research & Development Organization (DRDO) had to first ensure that they had a system in hand with the following capabilities:

1. The means to track an orbital object with extreme accuracy.

2. The capability to boost a kinetic kill vehicle (KKV) to the desired altitude.


3. A KKV that was accurate enough to hit a target moving at a relative velocity of nearly 10 km/s with respect to it.

The KKV is capable of shooting down hostile objects moving at 10 km per second at a far higher altitude of nearly 1200 km.

Now to Develop that We need Completely New Boosters For AD-1 And AD-2
DRDO already working on this for India’s next generation AD-1 & AD-2 ABMs are out. AD-1 will be able to intercept MRBM class of Ballistic Missiles while AD-2 will have the capability to intercept IRBM class of Ballistic Missile
