Helina has been worked on from 2009. Nag is about 30 years old now!!!!

is that problem? finally we don't have to import such atgm that is huge savings of foreign reserves.
and 30 years ago nag was different than today it is. it should be given new name so that people don't find excuses to discredit drdo..

Just correcting the facts!

As I've been saying Helina is actually more important than Nag! Between IAF/IA there's an urgent need of at least 10,000 Helinas!!!

Why is DRDO/ADRDE building an Airship (Hindenburg type blimp)? This is not an Aerostat.

Will it be used as a mobile aerial surveillance system that moves from point to point - slow AWACS?

But they're also simultaneously building an larger aerostat system (Prahari) - this will be larger than Nakshatra (Nakshatra being larger than Akashdeep).

Yes. It is being developed to act a aerial surveillance system for both the borders and for internal security!

IR based ATGMs are very costly and are not cost effective
USA is the biggest user of javelin missile but even they are finding it very costly
The cost of each javelin or spike missile is around rupees 2 crores even though certain news items try to understate the cost
In comparison the cost of Advanced milan or konkur missile is around rupees 20 lacs
But the dalals want to import the costliest items

All USA equipments and ammunitions are overpriced except for basic guns and bullets. The guns and bullets are also available in civilian models and hence the cost is low. Eclusive military only goods in USA is excessively expensive.

Javelin costs 1 crore, not 2 crore per unit. A small screw costs thousands of rupees in USA. It is not a surprise that Javelin has such price tag

Does that 20 lakhs include the license fee to French/Russian companies?? (India normally pays in royalties a sum equivalent to the production cost itself!)
And not to mention the amortization of the fixed costs of the plant??

Static, tethered low level air defence especially for low flying cruise missile. Though there are many variables like weather, terrain etc. to be taken into account, it is better to have the system than not.

I think you missed the entire point of my post.
DRDO is building an Airship: non-tethered & a moving blimp

Are you sure of this? Is there a source with more details? I though such airships were not considered as safe and hence discarded

They were considered unsafe for intercontinental travel using HYDROGEN filled blimp; because hydrogen is flammable (that's what happened with Hindenburg). Using Helium makes it pretty safe. It's more of a fancy ride thing nowadays than for serious travels.

DRDO's Airship will however be unmanned that will travel for days with surveillance equipment on board.

DRDO is simultaneously building a large tethered aerostat also - it's called Prahari!

I might have. I did not hear about a DRDO airship. Some kind of source would be appreciated.

These are tethered aerostats bruh. They are not going anywhere.

This publication has both Aerostat and Airship.

My bad. I overlooked it in a hurry.

Ironically, the tethered aerostat described in detail in that publication (Nakshatra) has been rejected by the Army! The current Prahari project (larger Aerostat than Nakshatra) hasn't been described.

Seems like after the TD for a small airship is successful ADRDE/DRDO will be building a Stratospheric Airship; something like this....

These will be great for surveillance - cheap, long endurance & out of reach of enemy missiles.

Ashok Leyland wins tender for defence tracked combat vehicles


NEW DELHI: Hinduja Group firm Ashok Leyland today said it has bagged a tender in the defence tracked vehicle space, marking its foray into the niche segment.

"As per the scope of work, the company will collaborate with Combat Vehicles Research and Development Establishment (CVRDE), Chennai, for manufacture, assembly and testing of light weight clutch for the design and development of weight optimised 1500 hp automatic transmission for main battle tanks," Ashok Leyland said in a statement.

Ashok Leyland Head - Defence Amandeep Singh said, as a part of the company's strategy to expand its business scope.. it has been working on tracked vehicles.

"With this win, we mark yet another milestone where we start working on the tracked vehicles that our soldiers use. We see huge potential in repowering and upgrading of existing BMPs/Tanks of the Indian Army," he added.

He said the tracked combat vehicle opportunity also exists in several other countries which use Russian made combat vehicles.

https://www.thalesgroup.com/en/worl...-airship-already-being-called-swiss-knife-sky

These will be great for surveillance - cheap, long endurance & out of reach of enemy missiles.

Here's my idea of how the Stratospheric Airship should be designed/used:

Endurance : 2 to 5 years
Power : Solar panels
Payload : 400-500 kgs
Num. req : ~250

PAYLOAD:

- PESA radars from Su-30MKI
Once Super Sukhois get new AESA radars, the existing radars could be fitted onto the Airships. The weight of the radar can be reduced from its current 400 kgs to around 250kgs simply by changing all the heavy metallic fixtures to some really light & not-so-strong fixtures. Current radar is designed to withstand upwards of 10g forces, whereas the Airship will barely encounter around 1/20 of it at the max.
The radar can provide 360 degree air-to-air (400kms range!) , air-to-sea & also ground mapping via SAR. To lower power consumption, it could operate in intermittent fashion - 100ms ON, 100 ms OFF(say)!

-Day and night/thermal camera with 50kms range

-ELINT/SIGINT


250 of these can cover the entire border (land & sea) and provide 24/7 long distance coverage, with very little operational cost!! And since they'll be at 20 kms altitude, no anti aircraft missile can take it down!!
