Seems kinda long missile.

What the f is wrong with people here...

We tested a effing BMD from a ship and there's hardly 5-6 post about it...you all seem more interested in whether 200gm explosive is good or 1.5kg

Only three such unique systems exist as of now and only five countries have developed them...
France - Italy = Aster-30
US of M = Aegis
Russia - China = S-300

There are so many questions. What VLS are we using? Which design it is? Based on existing AD-1/2 lineage or completely new? Explosive or KE?

And you all want loitering munitions

You are correct, we should be more excited. The reason is, BMD is such a niche technology that it might never see the light of day. Perhaps protecting coastal cities or from Chinese anti-ship ballistic missiles, but that too a far-fetched scenario.

Loiter munitions are more practical and effective. Likely to be used and be the game-changing factor.

But from a technological perspective things are absolutely opposite.

I can buy a Chinese FPV chassis with BLDC motors and propellers under 10k. Another 10k and I'll have a flight control systems together with GPS. The only thing I'll be needing now is few grams of ammonium nitrate and some ball bearings.

But just imagine the R&D for a naval BMD

Is this measurement accurate? This would make AD1 longer than Brahmos.

Anyone know what Israeli and Poland LMs were the competitors for this?

Hope, they start inducting canister launched LMs too in huge numbers.

For Poland it was for sure WarMate and for Israel it could have been Hero series, though I'm not sure

its mostly piggy backing off open source software.

Open source does not mean poor quality. Quite the opposite in fact in many cases

@AnantS , It might seem counter intutive, but custom encryption is dangerous. As of now, the existing key based encryption where you can generate large keys making it almost impossible to crack the encrypted payloads is a very good model.
Custom encryption can lead to some math wizard from a foreign country figuring out weaknesses in the custom encryption and we may end up in the enigma type of situation.

Open source models allow researchers world over to have a go at the encryption and figure out weaknesses and address them. While there could be someone who has figured out something, the rigour with which researchers try to break is largely public and weaknesses come to public notice sooner or later.

In terms of actual dimensions it may not be accurate but if you're calculating based in this particular image then it's pretty accurate.

The rim diameter of Tata LPTA is 20 inches and the diameter of the first stage booster is roughly equal to the rim; so it's too 20". That would be quite close to the 0.5m claimed.

As for it being longer than BrahMos; no it's almost equal. If you consider the length of BrahMos together with its cold gas generator then both missile's lengths become quite equal.

No open source doesn't mean Bad quality. But it would be considered lousy job if open source are not heavily customized to give your own flavor.

Well this sounds well and good of there are regular s/w updates like OTA or plugged. But right now these drones are burned with firmware and delivered. I doubt there are OTA upgrades available. Even if they were available how feasible will be for grunts to update their stocks at frontline. Custom atleast can give you control over variability of encryption logic in each batch. Now as as @binayak95 alluded, drones use customized version of open source. Usually companies who have their inyernal products based on open source usually have road map to keep on upgrading to latest stable release after through vetting. So you theoratically could have best of both worlds.

Only if we have a good ecosystem of researchers in crypto math & computers.

Otherwise, we can see dangers like this

Did they say that the range is 15 kms?
For a drone that size, aren't the logistics more difficult?

Folks I am back
And back with some queries
What's the status of nagastra 2 or LM1 which is actually anti tank loitering munition
Is it under development or is it under testing or something else

There is a higher chance that we will be having dedicated BMD vessels in form of NGD.

Uptill now what our radar range??

 

[ezsasa]

this video says INS anvesh launches do not required NOTAM. is this a correct statement?
=======
INS Anvesh – 1st floating missile test range (FTR) could have been used for Naval BMD trial
