in that case, not possible i guess because of 40 km range..
it is possible very much. Tactical N carrying delivery systems to enage with pak and china must be of short range.
Prahar missile is less than 200km , Nasr Paki missile is just 60km..

so this torpedo can do that too.

Can a nuclear warhead fit technically into torpedo?
Yes..

Does it make tactical sense to release a torpedo with nuclear warhead , which is launched from either from a ship or a sub which travels at a speed 15-30 knots released anywhere between 30-40 KM from shore?
NO..

yes it does because it would be element of surprize in case of incoming enemy fleet.

Being a layman I have similar doubt as one of the member that why we are going for german torpedo when we have varunastra ? is it because german torpedos can be launched from submarines and varunastra cannot or there are some other factors

This is a great achievement. Slowly but surely nau sena is inducting desi kinetic systems;

IRL replaced Russian RBU-6000
iTT replaced Russian TTs
OFB manufactured ASW rockets
Kavach countermeasure rockets
Maareech decoys
Brahmos missile
l&t uvls
Mr-sam (sort of Indian)
Ofb made ak-630
Bhel made 76mm cannons
Guessing ammo is made by ofb

And now finally own torpedo

Varunastra is just a ship based torpedo. Submarine based version is still under testing by NSTL. So we are importing submarine launched versions from Germany as stop gap measure.

Varunastra will also be adapted for use from submarine torpedo tubes. Trials will begin soon enough.

[tejas warrior] NTSL is developing heavyweight thermal torpedo (which will be submarine launched) and the name is Shakti thermal heavyweight torpedo. It will be a monopropellant fuelled torpedo.

Shakthi's propulsion technology is thermal which is quite different from Takshak and Varunastra. Takshak is the submarine version of Varunastra.

Sneek Peek into India’s Indigenous Torpedo Program


It was exactly 130 years ago when the first submarine fired a Torpedo while it was submerged till date torpedo is still one of the most powerful weapons in naval warfare, and will remain an indispensable instrument for upholding maritime security in future. For many decades to come it is unlikely to change . Yesterday out of 196 countries on Planet Earth , India joined elite few (8) Countries who have their own Ingenuously developed Heavyweight Torpedo programme when it handed over Ship-based indigenously built Varunastra Heavyweight anti-submarine torpedo to Indian Navy for which Navy will place orders for 75 of this HWTs for deployment in all its front-line warships . Naval Science and Technological Laboratory (NSTL) in Visakhapatnam which is part of the DRDO consortium of laboratories and also is the only establishment in India which has been tasked to develop underwater weapons systems for Indian Navy . let’s have a peek look into India’s underfunded Torpedo programme .

TAL (Light Weight Torpedo) aka Shyena : TAL is 2.75 metres long, weighs 220 kg and packs 50 kg of explosives which was inducted into Indian Navy on March 3, 2012, which was also India’s first production grade Torpedo which entered production at Bharat Dynamics Limited (BDL), Hyderabad. TAL is an electrically propelled, self- homing Torpedo with 95 per cent indigenous components which can be launched both from ships and helicopters. It can hunt submarines with a speed of 33 knots with endurance of six minutes in shallow and deep waters and can operate at a maximum depth of 540 metres Navy at that time had placed orders for 25 TALs.

Advanced LWT (ALWT) : ALWT is successor programme of TAL which has some minor corrections and major improvements over TAL after taking active feedbacks from Indian Navy . ALWT is still under development and little progress has been reported about it publically but ALWT was supposed to ready for trials by 2016.

Takshak : Takshak is heavyweight torpedoes (HWTs) to be launched from a submarine against other submarines or warships . Takshak HWTs is a submarine-launched variant of Varunastra HWTs with wire guidance . Takshak uses wire as a medium of communication between the torpedo and the firing submarine . If the wire breaks before it hits its target then Takshak becomes an autonomous torpedo like its Varunastra ship-launched variant which can travel up to a distance of 40 km for taking out submarines and can operate up to a depth of 400 m. Takshak HWT programme is key and significant torpedo programme which will be the main armament of many indigenously to be developed Nuclear Ballistic missile submarines and Nuclear attack submarines in future .

Shakti HWTS : India plans to develop advanced Thermal Propulsion Engine for Heavy Weight Torpedoes. Under development is a torpedo called Shakti with thermal propulsion, which can generate 500 kilowatts of power and rev up the engine within a second to propel a Torpedo to travel to its target at much higher speeds than what is provided by conventional propulsion .

DRDO-Developed, BDL-Built Varunastra HWT Handed Over To Indian Navy For Service-Induction

It was in the late 1980s that the DRDO’s Vizag-based Naval Science and Technological Laboratory (NSTL) initiated R & D work on developing three types of torpedoes: a lightweight torpedo, a heavyweight electric torpedo, and a heavyweight thermal torpedo.

The first, known as Torpedo Advanced Light (TAL), was meant to be a 220kg torpedo capable of being launched from warships and helicopters, have a top speed of 33 Knots in both deep and shallow waters, incorporate a self-homing guidance system, and was to be powered by electric batteries which would last for six minutes. It was only in 1998 that the TAL’s technical trials began, while user-trials commenced only by 2007. The IN began service-inducting the BDL-built TALs in 2011.


It was on December 24, 2008 that the NSTL had stated that the ‘Varunastra’ heavyweight electric torpedo being developed by it will be ready for service-entry by 2009. The Varunastra, weighing 1.5 tonnes, having a length of 7.6 metres and a 40km-range, was meant to be launched from shipborne twin-tube launchers already developed indigenously by Larsen & Toubro. However, it was only on September 26, 2013 that the NSTL stated that it had completed the creation of state-of-the-art facilities required for the design, testing and prototype production of heavyweight torpedoes like the Varunastra, meaning user-trials of the Varunastra were then still two years away.

The NSTL-developed Shakti thermal torpedo runs on monopropellant fuel, which can burn without oxygen and so is useful in underwater operations. Under development since 1996, the NSTL took nearly seven years to develop the engine and fuel for Shakti. The monopropellant fuel can generate 400kW of power and enable the Shakti to move at faster speeds (almost double that of an electric torpedo) and at depths of up to 600 metres. Technical trials of the Shakti are still underway in shallow waters, and user-trials won’t commence till 2016 at best.

This is the most important thing as of now ..

We need submarine based torpedoes more than ship based ..






will soon be fired from a submarine.

"We will soon be test-firing the torpedo from a submarine. Some minor modifications will be needed for that," he said.

Varunastra will also be adapted for use from submarine torpedo tubes. Trials will begin soon enough.

Their will be little changes to original design for quick adaptation, Besides wire guided is best regarding safety ..

Present requirement, is the need for submarine launch torpedo in mass ..

So can we assume that
Submarine launched varunastra will not be wire guided ?
