Jump in capability of Anti-Submarine Missiles.

While Anti-Submarine rocket/missile delivered systems are not new they have not been actively pursued by many countries recently, though the US, Russia, and Japan presently field them.

India has however recently tested a supersonic anti-submarine missile that carries a lightweight torpedo which can be released over a designated area that has a substantialy greater range than any presently in service.

India’s SMART or Supersonic Missile Assisted Release of Torpedo has a predicted range of up to 400 miles, releases its payload, the acoustic homing light torpedo which is reported to have an endurance of approximately six minutes or operational range of around 10 miles at a speed of 33 knots to try and find its target.

This greatly enhances stand off range now poses a hugely increased threat to submarine operations from the Indian Navy, who has recently become a much more active member of Quad in the coalition which is now standing up to China’s illegal expansion in the S China sea.

Don't you need to know where the submarine is before you fire a missile at it? A 400km sphere contains an awful lot of water.

I think you also need to know where it is after you've fired a missile at it. The sneaky buggers have a habit of not staying in the same place.

It's barking. 400 miles at mach 2 (for sake of argument) is 19 mins flight time. During that time, a boat doing 10 knots will have moved 3 miles (or one third of your torpedo range) and that's without any consideration of sonar accuracy, which won't be brilliant at that sort of distance.

Sorry, I missed separation, submersion and explosion in the video here, but some guy claimed it all happened anyway. Is this really the same nation that phones me twice a day about pretending to be my bank, or an accident I've never had? Doesn't bode well, really.

So an updated Ikara and still shite. Bugger to chip and paint after.

The range is so one ship can cover a wide area in which other ships can call in fire missions.

And the torpedo does 33 knots.

Remind me again why Spearfish was created.....

In most cases most weapon systems are not being used at the extreme limits of their range.

At 100 miles and 5 mins the torpedo will be almost on top of it.

And if the missile is receiving in flight updates from nearer sonar sources the sub will be pinpointed all the way.

Hardly barking.
 
On a tangent

but

could you imagine living on an Indian submarine?

I think they would recruit exclusively from the guys that go down gold district sewers to extract milligrams of gold fillings after a process that would make most people wretch their own arse through their mouth.
 
Nope, but go on then, please tell me how you get a targeting solution at 400km?

Keeping in mind @Not a Boffin's Post #5.
The last thought in post #13 answers that question quite nicely, maybe there are local targetting sources that can point to where the sub went.

Presumes an in-flight re-targetting capability which is secure and a very sophisticated battlespace C2.

In-flight updates from "nearer" sonar sources would be very advanced indeed.

It may be pertinent that 5 mins latency is a lot more than we tend to use when a launch platform is in contact with the target boat.
