India’s own Bond gadget spying under water

The independence I am looking for is at least traveling 10 Nm without external support. Highly doubtful for such a tiny sub. Let me give you some perspective. It weighs around as much as my Toyata Camry.

The task you are proposing would be much better done by a good diesel electric submarine.

Have you ever been or on a ship or a sub?
Do you even know how many auxiliary machinery a Diesel engine requires?
 
I haven't but I know a car sized submarine can't possibly hold that stuff at this point in time.

So pls take it from some who has been working ..a diesel engine for a 4 meter long sub not a good idea.

Battery pack of a scorpene sub which weighs thousand times heavier than this allows it to remain submerged for weeks time and run a 7 kts.

I know. That is why I am trying to disprove that this sub could have such range.

I think you misunderstood my post about the diesel sub. I was talking about using something like the Scorpene for such a task, not the 1.5 ton sub,

A sword can not do the job of needle.

A 6 meter tall(draft) 2000 tone submarine can not enter a harbor undetected... it will stick out like a sore thumb and will taken out by naval batteries.
 
Developed by the Naval Science and Technological Laboratory (NSTL), Visakhapatnam, the vehicle is a mini-submarine with its own intelligence and capabilities to launch surprise surgical strikes on any target across the seas.
Why are they talking like this. Weapons are not tested yet. When that is tested then only you can say that it can be used for attack purpose also.

A 1.5 tonne submarine can not carry weapons when even the lightest torpedos weigh around half a tonne like the mark 46.
Agreed, but it still a technology demonstrator, it could be easily modified to carry weapons in future.

Fine not the Scorpene but it still needs enough power to be independent. That is impossible now with a 1.5 ton sub. Something in the 100-500 ton range might work.
 
They are testing the technology,after that we'll build a bigger one..
And its a good innovation :cheers:

Not to be a buzz kill again but small submarines attached to ships for exploration have been used for years now.

I would be willing to change my mind if you could provide a source on this submarines new innovations that is more definitive.
 
Give a reason for your ROFL please or you will be regarded as flaming.

Don't expect anything more than that.

BTW I think you didn't notice that it is for surveillance, reconnaissance etc etc not a weapon. It is like UAV, not UCAV. It has sonars, cameras etc and doesn't meant to attack enemy vessels though DRDO working on larger one. Above all we should wait for more info.

you are correct on most of the points. just for clarification to all members, this vehicle is only for sea floor mapping. not related for direct military purposes at all.
stupid media made it sensationalist and some members got carried away.

OK buzz killer, its our first. We are not as advanced as you guys. Also i hope what you are talking about is unmanned and not just smaller submarine for surveillance. I also hope you share some articles on this stating that many countries have this tech. Don't tell later that only 5-6 countries have this capacity. Bye the way i really hope you guys have something like this because otherwise it would really ironic.
 
Here's the complete article.
The country's strategic defence research crossed a major milestone with the Defence Research and Development Organisation (DRDO) successfully completing the sea trials of the indigenous Underwater Autonomous Vehicle (UWAV), the marine equivalent of Unmanned Aerial Vehicle (UAV).
Developed by the Naval Science and Technological Laboratory (NSTL), Visakhapatnam, the vehicle is a mini-submarine with its own intelligence and capabilities to launch surprise surgical strikes on any target across the seas. The crucial phase of tests including its launch from a defence ship and manoeuvring through various depths began early last December. The results were evaluated through January and a confirmation that the tests had met all parameters was arrived at this week.

With this, India joins the league of naval powers with indigenous prowess to propel an unmanned, underwater vehicle that can give jitters to its opponents. The 1.5-tonne, 4.7-metre vehicle can stay underwater for any number of days given the fact that it is powered by silver oxide fuel cells, a variant of the ones used in ballistic missiles.

Once launched from a ship (the sea trials were done from Sagardhwani, a research ship operated by Kochi-based Naval Physical and Oceanographic Laboratory (NPOL) in the Bay of Bengal), the vehicle can dive up to a depth of 50 metres and cover "many nautical miles", sources said.

"We can programme it for a specific mission and once launched it will complete the task and reach a prescribed rendezvous. We have also developed a special launcher for launching it and reclaiming it," sources told this newspaper.

The programme will now move to a project phase where the NSTL will work closely with the Indian Navy to weaponise the UWAV.

Top sources said the UWAV will also serve as a prospective carrier for BrahMos supersonic cruise missiles. "The advantage is that we can launch it from our waters and wait in safe waters for her to get back after the mission. And at any stage of the operation, we can intervene and control her using remote techniques," sources said.
Underwater unmanned vehicle trial successful
So, obviously this a scaled down technology demonstrator prototype. Further development will depend on the success of this experiment.
