Indian Ballistic Missile Defence Programme - Updates and Discussions

There are multiple videos from Russia- Ukraine war of Cruise missile being shot down by MANPADS.... They are fast only if they are flying directly over your head & your line of sight is compromised but even then they can be shot down in most cases.


Yeah, I know. It has always been possible from some aspects when you have sufficient LoS, like at sea. But stuff like this is extremely rare, it's not the norm. Many of these missiles are noisy turbojets, but Pak and China's missiles are less noisy turbofans. And the vast plains in those regions allows some level of LoS. We don't have that much convenience.

What we are looking at is merely the incompetence of the enemy firing their CMs, because missile routes generally pass through holes in defenses. In reality, no one has the convenience to actually be holding a MANPADS while a CM flies close enough for engagement. That's why pretty much all ADS units stick MANPADS on vehicles and have them all spread out.
 
Disagree. Igla manpads (shoulder-fired at that) are used for last ditch missile defence on most IN surface ships to this day. If manpads work in the naval context, why wouldn't they work over land? What's needed is a stabilized launcher (like France's SIMBAD) with integrated eo/ir + cueing from onboard FCR to improve detection time and kill probability.

This is one area MANPADS do work because the CM is headed towards you, the speed then becomes inconsequential as the target increases in size. And you have sufficient LoS.

In this case, the ship is the primary sensor, and the MANPADS is depending on cues from the ship followed by eyeball Mk1 to hit the target. But this requires a certain level of failure in the ship's primary ADS that forces one of the components of CIWS to step in before guns take over.

But in the plains, infantry isn't walking about like that, they have to stay hidden, ie, if the enemy was actually competent enough to threaten them. Plus missile routes are actually mapped beforehand, so CMs flying close by is not something that's as common as people expect.

That's one of the reasons why ATGMs have slightly unpredictable paths to prevent MANPADS from targeting them.

You have to take into account night time conditions as well.
 
Terrain matters as Ukraine-Russia example showed, but all the videos are of day time iirc, so maybe capable but not completely. What I think is can we have a ground based acoustic sensors across the border and even have them on top of Power Cable Towers etc. To give Early accoustic warning of low-flying cruise missile, drones or even jets, Helis etc, Is it even possible?

US stealth is defined in Acoustic spectrum also, especially for LO helis like the one used in OBL raid, where noise suppression was used in Blades design or something.

Acoustic sensors can be fooled or saturated by drones.

It's almost humanly impossible for MANPADS to shoot down low-flying CMs in any capacity. It's doing 700+ kmph. You won't hear it coming, and by the time it's over you, you look up and it's gone. So MANPADS are meant for slow-moving targets like small drones and helicopters.

There are so many videos from Russia-Ukraine where Ukrainians are using MANPADS to shoot down sub-sonic CMs AFTER they have passed over them, so in a tail chase mode and I have seen successful interceptions as well.

Addressed in previous posts above yours.

Only vehicles with staring arrays can, with some luck. In reality, you need low-level radars on the ground and airborne look-down radars.
A Cruise Missile doesn't do 700kmph at that low altitude. Most Cruise Missiles quoted speed are for high altitudes, at low altitudes its atmost 300 to 400kmph, which is doable to shoot down with IR Homing MANPADs but the engagement envelope is quite small, unless we are standing less than 300m from loci of Missile path.

Not at all, Tomahawk does almost 900 kmph at low altitude.

I wonder if our IACCS is geared up to detection & tracking sub sonic low flying CMs . If that be the case , the last ditch defence can always be the equivalent of last mile connectivity viz the last man in the OODA Loop equipped with a MANPAD be it shoulder fired or preferably tripod mounted.

Procurement & distribution of such armaments with necessary E/O sights for target detection & acquisition can be done in the thousands.

I'd advance this particular line of argument especially to the LAC when we go up against China facing Drone swarms , CM swarms & low flying VLO / LO FA. Station Mountain Warfare SPECIALIST Infantry on peaks or high ground with surveillance & tracking equipment along with these MANPADS to do the needful.

Frankly I don't think this is in the realms of sci fi or futuristic warfare anymore. This IS the time for it .

What are your views ? @Rajput Lion

Most manpads (Mistral, RBS-70) are advertised specifically as having anti-missile/point defence capability at low altitude. I don't think any mfgr would risk upsetting customers and bad press if that wasn't the case.

Many of these systems also come with integrated C2 out of the box for integration into upper echelon C4I like IACCS . If not IACCS, I'd be surprised if the Army's own Aakash Teer didn't have CM tracking capability.

Forward observers in border areas have always formed the first line of our ADGES. They likely carry manpads to shoot at targets of opportunity.
 
Nice pic by TRET.

In which case our ITCM Nirbhay , while it'd have greater chances of success against Paxtan will have limited utility against the Chinese.

Whereas previously there were a few here including myself arguing for fast tracking the development of various iterations of the Nirbhay viz the Air, Sea & Undersea versions of it apart from the land version to be inducted in the thousands in view of our upcoming war against China.

Could that be the reason we haven't seen much activity on that front? Prima facie it would seem so.

Looks like we need to focus more on expediting final certification of the STAR missile ASAP as well as it's air launched version for the royalties we pay Russia for the Brahmos is simply too high rendering huge quantities unaffordable apart from the dependencies it creates on them for the RAMJET engine which is going to bite us in conflict time.

Unfortunately this administration is heavily into penny pinching & extremely stingy when it comes to spending on defence procurement. What we're seeing now vis a vis a supplementary budget of ~ 50,000 cr is merely sum allocated to replenish stocks used in the current conflict apart from limited augmentation.
 
We did see more work on ITCM front than before. Was a matter of replacing the engine with domestic made one. Since the manik are all sort of LSP/proto units and in one test the engine igniter did not work so it plunged into the sea after booster burnout, it should get some repeated testing to prove the engine first. We have seen one LT internal report on this as well. So after 1 successful test of ITCM, there should be few more rounds to prove the ground launched version is stable and reliable. Once this is proven the other versions work can proceed esp the air launched version, in similar manner how Brahmos evolved. The sub launched version is being done in parallel and secretively so we won't know status unless they tell us.

basically way too many programs are going on at the same time and all of those need large budget, while finance dept continuously release lesser fund than requested , plus the really shortfall in manpower as well.

Imo subsonic CMs are still viable. For eg: Russkie Kh-101s have had a fairly good strike rate in Ukraine. You'd have noticed in some videos that they carried onboard countermeasures like flare dispensers (+stealth shaping) for increased terminal stage survivability. Thus far the Nirbhay program's focus seems to have been proving the basic design. Perhaps future Nirbhay variants will have better ew/sp features.

Very interesting👍. We aren't there yet but we're most definitely heading in the direction that you have alluded to.

Almost all these cruise missile interception by MANPADS happened during day light for obvious reasons......Stealth shaping is the way forward & speed..... What we really need to do is massive investment in SRBM like Iskander, Lora, PrSM type Systems.
