Whats this ??

................................................................
These are for the indian nuclear submarines

Nuclear submarines spend most of their time underwater.

And lot of garbage is generated by the crew ie leftovers from meals etc which need to be disposed off.

For that a garbage disposal chute is used.

It allows the ejection of garbage even when the submarine is underwater.

It is a risky process , however thoroughly tested and vetted.

Garbage is collected in special bags and tied to bricks / weights to give the necessary negative bouyency so that it sinks to the bottom . It is then put into the chute , it has interlocking doors , after the inner watertight doors r locked , high pressure air is released to eject the garbage bag out of the submarine and then the outer hull doors are locked.

Principle is same as that of a torpedo being launched from a torpedo tube.

(A submarine general area of operations / patrol route even during peacetime can be determined by tracking the wastes it's generates , so this technique is employed to keep its location from not being discovered as the garbage gets dropped to the bottom of the sea )


Secondary purpose of this is to launch distress or signal cartridges


Another purpose if required under extreme special circumstance is to deliver coded messages/items of interest etc etc tied to a water proof container with a colour marker unit to the surface for retrieval by friendly helicopters or ships. This is done if the submarine cannot communicate or cannot surface or is under EMCON or wants not to for what ever reasons .

The container ascend rate is predetermined so as to allow the submarine to leave the area before the container floats to the surface and releases it marker a pre-determined time limited colour/dye which spreads on the surface for easy visual contact for the sub surface or air borne retrieval party

Explain whats inside .......................
It's initial purpose was for the transport of completely integrated nirbhay cruise missile from the labs to the test site.

You know nirbhay suffered technical problems due to it being assembled in the test site where adequate support facilities was not available. Later launch failure was tracked to this reason.

Decision was made to do the integration at the labs and transfer the same to the test site for minimum risk to mission success.

Later on it was decided to expand the scope and usage of the system for other tasks as it allowed to use the same system to transport articles of interest in a safe and secured manner without any compromise to the integrity of the said articles. It has been operationalized and in future other articles under development will use it with necessary modifications

This is my most interesting picture of 2018 which I found

View attachment 29843

This thing might look simple but what it implies it does is really intriguing and has great implications on how capabilities are far more then being claimed in the public domain.

No direct info on what the thing does is available , all it says is it is

1.for providing stabilization to the cannister

2. reduce load on the article under external induced forces (obviously it means firing load / stress )

3. Reposition the cannister to initial position after article is expended and cannister finishes cylic movements

4. Lastly move the cannister into the lower pre firing position

**********************

Definitely a cannister based missile but what the fuck is this thing part of ?

The system does not fit any know system in the public

Which cannister based missile needs stabilization and shock absorbing mechanism and then the cannister after firing it's missile undergoes cyclic movements to return to its initial position and then transitions the cannister to even lower pre launch position ( i believe storage position ) ?

Damn this is some serious stuff

Guys what do you make of this ?
I forgot to mention this

This system is related to naval application and around 45 numbers of these has been delivered.

So is it for submarines ?
But the silos are fixed in Indian SSBNs
If k15 then the 3 cannister rounds are fixed in position
If K4 then 1 cannister round fixed in position

So why are the cannister (s) being moved around in their silo ?

Unless the silo has a revolver like launch system where the cannisters are rotated and loaded into launch position ( hatch opening ) and fired and then successively the system is rotated to load the other cannisters one after another for firing. Then it means there has to be more the 3 cannisters of k15 per silo.

Or maybe it is for the LRSAM , kolkata class destroyers 32 rounds is too low , there was rumours of underdeck reloads of additional 32 rounds.

One thing I know for sure that Russians employ revolver type cannistered missile launch systems in the ships underdeck.

Don't know it's crazy :doh:

Concept i alluded to is something like this one , just to give a rough idea , no need to be exactly same.

The stabilized canister thing could be for Dhanush ASBM. Ballistic missile INS do need a stable platform for location fix.

Its canister stabilization for k15 size of missiles......from the looks of picture.

In cold war, US used to recover these garbage from Soviet subs. We need to think any other solution.

BENGALURU—India’s national defense agency has successfully tested a new Stand-off Anti-Tank (SANT) missile meant to bolster the military’s multi-platform launch capability.

The missile was tested Nov. 29 at the Pokhran field firing range in the Jaisalmer district in the western state of Rajasthan. It was developed by Research Center Imarat (RCI), the premier laboratory of India’s Defense and Research Development Organization (DRDO), in association with the Indian Air Force (IAF).

“All the mission objectives were met. A dummy target was destroyed and the missile was successfully flight tested for different ranges, including the maximum range capability in [the] Pokhran field firing range,” a senior Indian defense official said.

The missile is believed to be a further development of DRDO’s HeliNa, (Helicopter-launched Nag) missile, which has a range up to 8 km (5 mi.).

The SANT missile will have a range of 15-20 km (9-12 mi.). It is equipped with a new, nose-mounted active radar seeker to help keep the launch platform at a safe distance from the target area.

The missile has a multi-platform capability and can be launched from attack helicopters and high-altitude/long-endurance drones. It also can be integrated with strike aircraft to provide high-precision, guided, tactical air-to-ground capabilities to carry out anti-armor missions. This would enable it to take out main battle tanks and armored personnel vehicles.

Active radar seeker basically makes it a Brimstone.
Maybe DRDO could eventually add a laser homing guidance kit which would make SANT a dual sensor like the newer Brimstone.

This the defacto way in which garbage is disposed by nuclear submarines all over the world .

Incinerator is not used because it will over load the onboard scrubbers , the scrubbers are purpose built to deal with carbon monoxide and carbon dioxide only . Other gases in large quantities will destroy the membranes.

Indian scrubbers onboard indian nuclear submarines.

Stabilization is not point of contention here

The red herring is the movement of the missile cannister inside the silo both cyclic movement and up and down transition from stowage to pre firing to launch position which does not fit with the operadi of K15 cannister in the submarine silo

Anyways you can be right or I could be right or both of us could be wrong .

Keeping all options open.

Interestingly 45 nos of such system already supplied

We have immovable submarines . ............................
Yes I too have the same feeling

But still why did they classify it as a naval system. Misinformation maybe

Or maybe for submerged pontoons :biggrin2:
Not a bad idea either for tests or otherwise isn't it ?


Why make things easier for the enemy ?

Many don't know prahaar and Shaurya are in active service , though in limited nos.

Newer version of prahaar was asked by army because they wanted a higher specific impulse propallent ( higher velocity ) plus other changes after limited operational usage during exercises.
