IN P8Is and SU-30 Escort off the coast of Pakistan

[Khafee]

This is incredible (if true)!

What is the source of this info if you don't mind my asking?

Note: Pure speculation

 

[Khafee]

I don't think PN has Sub Rescue Platform, I do stand corrected about INs having theirs delivered.

The one IN has, have a look at the max depth it can operate. It would have been useless, in this scenario.

 

[MIRauf]

650 Meters diving depth, you are right, it be useless for this. If there was an explosion, waiting for USN SOSUS to confirm it, sooner or later it will come out. How are PN's SOSUS capabilities ? do they have any deployed around their areas ?

 

[space cadet]

at the depths that I think you guys are talking about, a sub would have imploded before it ever hit the bottom. But this is all speculation, I think the P8 was just doing some ISR

 

[Blackbirdz!]

1) The proximity to Kekra1 is no coincidence.

2) They tried to booby trap Kekra1 well heads, via UUV

3) While trying to deploy UUV, via the torpedo tube, it blew up. Taking both to their watery graves.

4) S21, a Scorpene class sub, was in that area, and in all probability is the one lost.

Watch India's Deadliest Sub INS Kalvari Dive Underwater, Shoot Missiles bwahahaha

 

[MIRauf]

They were not in our EEZ they were in our territorial waters....

within 12 miles off the coast ?

 

[Thorough Pro]

There is no shortage of stupidity in India, if their highest leadership can award a medal to a loser pilot for shooting down a phantom F-16 without firing a missile, they can do anything.

A sub is too significant to hide...it would be stupid if they attempted such a thing.

 

[Thorough Pro]

PN knows we don't need to waste any ammo on them, IN is quite capable of sinking its subs in knee deep coastal waters

i doubt PN would sink the sub, I can only think of an accident...

 

[Thorough Pro]

Rescue would be if the personnel are alive, salvage would be for the sub

Are Sub salvaging and sub rescue 2 different things? I don't think the depths were are talking about there would be any survivor after 4 to 5 days.

 

[Thorough Pro]

I think we do, but the rescue is possible only up to a certain depth. For personnel rescue, the equipment should be onboard the sub to let them escape. Easier said than done.

I thought it was a Scorpene sub...India is going to have six of those(well 5 now?)...so it would be immensely helpful if Pak could get its hands on one.

I'm surprised to know that Pak doesn't have a sub recovery system...considering that PN has 5 subs plus a few more midget subs. So what exactly is the plan if something happens? The crew is left to their fate?

I've never heard of a submarine with rescue equipment onboard for its personnel...so they can escape. When a sub sinks...I've only read the news of other sub rescue assets going after it.

Usually most single hull submarines around the world can operate in a range of 300m to 400m depth...others can go even deeper. So if a sub is already 300m under water...and something starts going wrong and the crew loses control...at first the crew will try everything to fix the problem as they would have been trained to do bcuz I highly doubt that jumping ship would be the first thing they were trained for. This would cause the sub to sink further...now consider the pressure difference on the inside and the outside of the sub. It would probably become impossible to open any hatch with human strength...
...if the hatch is powered(to overcome the pressure difference) to allow for it to be opened in case of emergency...then it would only work if the power generation system on board(or batteries) are still working. If the power has failed then it's the same problem of pressure difference keeping the hatch closed forcefully. Even if the hatch is opened somehow...now that water will be gushing in with extreme force again owing to pressure differences...and it would make it hard for the personnel on board to exit out of it right away. They would have to allow for the water to fill in so the pressure differences can equalize a bit...in which case now with water filling fast they will be sinking further which could be highly dangerous for the human body. If they do make it out... optimistically at 400m depth...their bodies will be subjected to going from 1 ATM of pressure to 39.6 ATM of pressure in a matter of seconds. This is for the subs that operate at some of the shallowest depths(300m)...and assuming the crew decides to escape rather quickly after trying to regain control...and the sub has sunk only another 100m.

If u r aware of an example where the crew escaped a sinking sub at some depth...plz do share...I would like to know.

I would think that the only way crew can escape themselves from a sub...is if it has sort of UUV(except not unmanned in this case) like escape pod. If the sub is lost at depth for whatever reason...the crew goes inside this escape pod...which can almost be ejected like a torpedo. This is just purely speculation on my part.

Allah O Akbar, isn't this the same one which was lurking around our waters after 27th?

That's already covered in my post...as in it assumes a depth of 300m or more.
...the suite is for ~180m depth or less.

My post is regarding 300m depth or more...which is pretty standard for submarines. From that depth...the crew would need some sort of a escape pod like thing inside the submarine...or other assets will have to be deployed for submarine recovery(which is how it's done around the world).
