Indian Sonar and Torpedo developments

Did you loose the train of though? You claimed pumpjet is part of french help not me. I was asking for evidence.

Its been a decade since projects like shakti has been closed. People like you living in MMRCA era.

I think you should read again. I said we do not know what's part of the collaboration and that DRDO already has a pumpjet program.

As for Shakti, you mean a program that apparently ended 10 years ago by your claim, but was tested by the IN only last year? :rolleyes:

Also, MMRCA is still around, only under a different name.

This is varunastra 🤦‍♂️. Shakti was a separate program.

This is the sub-launched version of the Varunastra called EHWT now renamed Takshak. (improved battery, higher speed and other tweaks iirc)

What your snippet talks about is a program before Shakti torpedo, and Shakti is the weapon that was to be pursued if the old pumpjet design worked as intended. It's like if HSTDV worked, we will make a weapon using it, but if it failed, we would go back to the drawing board.

So the old pumpjet TD ended, replaced by a new program in 2018. But the Shakti torpedo itself still exists. The issue is they made the mistake of naming a TD project "Shakti" instead of some forlorn abbreviation like HSTDV or SFDR.

In any case, going back to the earlier claim, foreign collaboration is not expected through direct import, we want to refine our own tech. The indigenization expectation is 95-97% for SSNs, so it's obvious we are looking at a domestic project.

Any reference to your claims?

Not sure abut this. EHWT is a clean sheet design. Sub Varunastra will be ready soon, its less ambitious. cc @marich01

The issue with TDs is it's difficult to get such data on the Internet. But you can see previous examples like Astra and Nirbhay. Astra went through 3 design phases, the first 2 became TDs. And Nirbhay transitioned to ITCM and LR-LACM. So DRDO stopped naming TDs and started using abbreviations, with names coming in later. Shakti is from the same era as Astra and Nirbhay. DRDO also made another change, where they will showcase technologies only after the TD phase has progressed sufficiently or has completed.
 

Italian 'Black Shark' back in contest for navy's torpedo need​


Italian 'Black Shark' torpedo, which courted controversy more than a decade ago after it came under allegations of corruption and irregularities, is back in contention for an Indian Navy requirement of heavy weight torpedoes for the Kalvari class submarines.

Manufactured by Leonardo, erstwhile Finmeccanica, the torpedo is being considered for the requirement of 48 heavyweight torpedoes after the Italian company was taken off the blacklist. Other options for the estimated ₹3,000 crore contract are from Germany and France.

The Navy has been seeking to acquire new HWTs for over a decade now. The last bid was a competition between a German and a French torpedo for the requirement, with the French F21 coming out to be technically compliant and the lowest bidder. However, the contract could not reach the signing stage.

The defence ministry subsequently approved a two-pronged plan - acquisition of a limited quantity of 48 torpedoes to meet immediate requirements from a foreign vendor and a Make in India plan for the larger requirement. Defence Research and Development Organisation could take a lead role on the indigenous project by roping in a private partner.

The Black Shark was the frontrunner for a requirement of 98 torpedoes in 2008-09. However, the project was dropped in 2013 and the case was referred to the Central Bureau of Investigation by the defence ministry.

Do anyone know the specifications of ALWT motor ?

Not the motor specifically. But we do have some information about the ALWT's performance figures:

@Ashwin found the spec sheet of the ALWT I was looking for. From MoD Annual Report 2018-19 :
View attachment 14228
The ALWT is on par or better than most lightweight torpedoes out there in the world today. The only thing left to improve upon is the maximum depth. Right now operating depth is at 600 m, assuming a safety factor of 0.8 the maximum attainable depth is 750 m. There are torpedoes out there with 1000 m maximum depth. Of course with the upcoming SMART engagement ranges that were previously impossible will be attained. Range and speed will be further improved when the high energy density batteries come. DRDO/NSTL was also working on super-cavitation technologies for underwater weaponry.

Well since you made a thread let's keep these photos of the ALWT here :

In the recent years we have seen an unprecedented expansion of domestic EV components manufacturers. Much of this tech can be weaponized.

New Indian start-up making a number of electric motors for 2-wheeler: scooters to performance bikes, 3 wheelers, forklifts, cranes, robotics etc. Their motors are based on the axial flux technology.
