Is aad the xrsam....

Or aad and xrsam s are different

Different.............................

Interesting point to note
SAMs need to pull much higher G's than a ABM interceptor.

If the rendering is accurate than Vishakhapatnam class destroyers seems to have more no of cells in front of the bridge.
ie 4 distinct VLS cell clusters in the front section.

No idea , first we will need a geostationary satellite with capability to support links to UAVs etc 24x7.

If we have that then utilising SATCOM on UAV is no biggie

The Rustom-2 is currently capable of operations up to 300 km away from its control center with UHF and C-band links, and much longer away with SATCOM, still under test from live fist

Satcom under testing means we hv that geostationary satellite may be

We already have this capability in GSAT 7A. GSAT 7 also may have same capability. GSAT7 is for Navy exclusively while GSAT 7A is 70% air force & 30% for army. GSAT 7A is having 10 transponder each of which forms spot beam to get high focused data up & down-link..

The USA predator drone earlier had 5Mbps data link which has now been upgraded to 30Mbps in reaper drone. If we take India to be using 5Mbit link itself, then for a satellite like GSAT 7A with 4Gbps, theoretically about 800 drones can be commanded.

GSAT-7 has already displayed this capability of network centric warfare by connecting about 130-140 vehicles (ships and aircrafts) in an exercise.

Some other sub systems of the himshskti integrated electronic warfare system

Reciever and listening post

Don't know the function of this one

 

[porky_kicker]

Not long age there was news of integration of consoles on the INS Vikrant

This is the one - operator station of CMS ( Combat management system )

 

[porky_kicker]

Always wondered what this onei is for

Logic says interception of uplink streams at the satellite end , given the size of the array. Not sure though. Definitely military that I am sure

Anybody recognise this tarpaulin covered vehicle ?

:biggrin2:

 

[porky_kicker]

This one is also classified as a "special Vehicle"

 

[porky_kicker]

From ISRO slide , interesting though

 

[porky_kicker]

Whenever I see a tarpaulin covered truck , I get jitters

 

[porky_kicker]

For which missile I wonder

Cubic has better solution which is man portable upto some level I guess

Well it’s not a system but just the antenna.
https://www.cubic.com/solutions/c4isr/protected-communications/expeditionary-satcom

Anyway I can see a lot of improvement can be made on the current one as well. As the current one is using a generator they can be changed to FTR (fuel trailers look at ensol solutions) depending on the power requirements

Hi guys

Baba Kalyani has already said that next ATAGS will be lighter in the weight. so light gun is already in making. Just wait and let Tata and Kalyani make another prototype. The issue will be resolved.

That is a very good thing. They will do it as they ahve to sell it. Unlike DRDO who will go crying to DS / RM and push it down Army's throat without doing any thing.

Since India would be requiring about 1050 towed howitzers I wish ATGS is at least half of it. Why so ? because of production and delivery schedule. If complete order goes to ATGS, it will take them 10 years to deliver 1050 howitzers. Army would want it in time.

Baba Kalyani is the man who can make 50 pieces of ATAGS per month if MOD gives him the order. He has built Bharat Forge to a level that it supplies forgings to all automobile majors in the world. Bharat Forge products are found in German and American autos. Absolutely exceptional man and exceptional company.

Tell us how does it matter ?
Is that laid down PRFI ?
Tell us why should IA be paying 4 crores more for ATAGS compared to AtHOS and Dhanus ? Because it has larger chamber ?
Larger chamber has increased the weight of the gun. Is not it a negative factor as compared to other two guns?

Introducing unknown, undeclared factors likr mini nucs has no meaning unless that is what Indian Army is asking for. Firing a mini nuc with 155mm Howitzers is a matter of doctrine which Indian Army will decide and not DRDO or Baba Kalyani.

True sir missed the ranting against OFB and DRDO in this post though .

1. Money will remain in Indian economy this time . And 4 crore etc will be reduced too once it enters into mass production and get refined . It isn't a major concern right now.

2. Nuke shells firing capability is an added advantage if we can create such shells than 1000+ guns ready to fire them up at Porks at 40km + distance will provide tactical advantage to our troops.

3. Weight issues have been known and will be sorted out as per statement from manufacturers "Jaadu ki chadi to hai nahi " that one said and it's done.

Indigenous capability development is key for defense sector in India to back the forces else the morons sitting around will keep import ing from socks and shoes to toothbrushes.

Let the army make a call and MOD think on that.

Boss avalanche can be triggered by an explosive charge.

Yes microwaves can be used as well as water absorbs microwaves. But explosive is more efficient.

Creating a mobile particle accelerator with enough mass and energy in the beam is no small challenge.

Unnecessary extraneous issues being brought into the subject.
Our Scientific community is more of James Bonds and very less scientist inventors or problem solver.
They offer everything else except for what is asked for. That has become a survival doctrine for DRDO.
If Indian Army asks for MPATGM offer them a 40 kg missile. If Army wants a sub machine carbine / gun offer them Trichy Rifle or Ghatak or an LMG instead.

ATAGS is 25 ltr chamber :capacity : as compared to 23 ltrs of other guns.

and
https://www.thehindubusinessline.co...ogramme-on-high-trajectory/article9854276.ece

The larger chamber results in higher pressure and in turn to longer range but at the expense of higher weight. So, this is what I intended to say. Since AtHOS has same chamber capacity as Dhanush, it makes little sense to select it

Size of chamber is not critical issue but the weight is. 23 ltr chamber is good enough for highest BMC and for achiving 45 km range. It can fire all kinds of existing ammunition including a mini nuclear shell.

"Mobility" is important for Indian conditions and weight is a factor that impinges on mobility. Simple.

For the moment Dhanus has no comparsion with ATHOS as the former is 45 caliber Howitzer and later 52 caliber with a range of 38 km and 45 km respectively. Inspite of that ATHOS is cheaper than Dhanus

Dhanus will have to come up with 52 caliber howitzers, a technology which OFB have developed for ATAGS and therefore should be easy without incurring any additional cost in developing a technology They have all basic wherewithal im matellergy and forging capacities hence should be competitive in pricing.



Let us see how things work out. They are in competitive process so they better pull up their socks rather than pulling strings.

Indigenous Might
Kalyani Group facility to produce 250 ATAGS a year

Younis Ahmad Kaloo

At the recently concluded 10th edition of DefExpo, which witnessed the participation of 671 exhibitors, of which 517 were local, India’s defence manufacturers had on display their sophisticated weapon systems and offered them as solutions to modern-day needs of the Indian armed forces.

Kalyani Group’s stand


Kalyani Group, an Indian multinational showcased five-gun platforms, including the 155/39 calibre gun system called Ultra-Light Howitzer (ULH) which was launched at the exhibition. Termed the ‘futuristic artillery gun’, the ULH comes in two variants: the conventional Recoil ULH and Advance Hybrid Recoil ULH.

According to the company, Conventional Recoil ULH is a 155mm/39 calibre long range field artillery weapon system weighing less than 4.8 tonnes. While Advance Hybrid Recoil ULH is a variant of Conventional ULH which incorporates state-of-the-art advanced recoil system, thus further bringing down the weight of the gun to less than 4.5 tonnes.

The guns, as the company said, have been explicitly designed to meet the growing requirements for flexible and accurate artillery fire support capable of rapid re-deployment by the battlefield helicopters and also being towed by lightweight limber or utility vehicles. Moreover, the ordnance of both the guns was proof fired at P2 pressure March this year at CPE, Itarsi.

“Kalyani Group has always been at the forefront of technology and is today a one-stop solution for artillery platforms. The ULH is a complete game changer and puts us straight up on the world map. We have designed and developed these ULHs which are futuristic in outlook and use. This will ensure that the solution remains valid and in service for a very long time, thereby proving to be cost and effort effective solution. These guns are the perfect example of ‘Make in India’,” said Director of Kalyani Strategic Systems Ltd, Rajinder Singh Bhatia.

Chairman and managing director, Bharat Forge, Baba N. Kalyani while addressing a media gathering at the exhibition also spoke about the features of the gun and offered it as a solution to the Indian Army’s artillery requirements in tougher terrains.




“We have a tough job carrying artillery as compared to China, which has built four-lane roads at the top of the mountains. Our ULH can be lifted by a helicopter,” he said.

Kalyani Group’s other artillery products include Bharat 52, Bharat 45, Garuda 105 and Advanced Towed Artillery Gun System (ATAGS), which it has developed in partnership with Defence Research and Development Organisation (DRDO). The Group’s contribution to the making of the ATAGS involves gun structure, gun control and automation, barrel and breech and battery command post.

“We have been able to fire up to 48 kilometres in range, which is the highest ever range that a 155mm/52 calibre artillery gun has been able to achieve in normal ammunition. The consistency and accuracy of firing is extremely good. The gun is very stable and has fired more than a thousand rounds so far and has had no trouble,” said Kalyani at DefExpo-2018 in Chennai. “We a have plant ready which can produce roughly 250 guns a year,” he added.

Exhibition apart, Kalyani Group also made some announcements about forging relations with foreign companies and expanding the product profile. In one such announcement the company said that Kalyani Group and Technodinamika, the holding company in Russia, have decided to come together to form a strategic partnership for producing the undercarriage systems in India for all types of aircrafts. A memorandum of understanding (MoU) was also signed in this regard. In yet another announcement the company said that along with TR Research and Development Ltd. it is working to develop and provide diving support systems, unmanned underwater vehicles/ autonomous systems and batteries for Indian defence.
