Jaguar's over Sow lake . Jaguar's included US made CBU 105 Sensor Fuzed Anti Tank Smart bomb in its arsenal. Chinese Light Tanks will get enough bombs to eat.

I believe we need to develop a dedicated ground attack aircraft for Himalayas

This bomb is a game changer which we use.

Something on the lines of A-10 Thunderbolt. But we arent rich enough for that and need to be content with Jaguar and Harpy.

Range 150 km

It’s pretty good considering the nose cone size of Tejas, the same Uttam can give 400km in Su-30MKI.

It will not only decrease dependence, but will increase our GDP growth, R&D, Employment, And will make sure this money used in R&D will only give better equipment in future.

I smell lie here .


They can under stating like most other manufacturer , with 700 or so module it can accommodate , i would argue for a 250 range , maybe 150 km is for 0.1 m^2

DRDO UXOR Robot

I don't know what is this. But the news tells DRDO developed Sonar Drone.

DRDO has developed a Sonar Drone for the Indian Navy.

DRDO's Sonar Drone Model that has already been fitted on INS Kolkata and INS Chennai. The Indian Navy has placed an order for 10-15 more sonar drones.

Swarm of Unmanned Underwater Vehicles and Autonomous Under water vehicles powered by AI and different kind of Underwater sensors are the future . Similar like Swarming Drones and Swarming UGVs DRDO also working on Swarming UUVs . And another important product which is under development is AUV mother Ship, which can carry numerous AUVs launch and recover them .

You mean to say a 90-110 tonnes displacement interceptor craft can't have it because it requires different mount, power system and control unit?
What's the weapon system with USN mk-vi patrol boat? A boat having 70-80 tonnes displacement?

And coming to roles, it is evident that authorities deem it to be within the envisioned roles so they are trailing it and are it talks with Elbit and OFT/BEL for local production.

Whether finally authorities decide to include it in the platform is a separate issue but that things have proceeded to what I have appended in my previous responses points to the fact that I shall not be able to accept your response on face value.

That being said, we can wait for a couple of years to find out if these puppies make it on the interceptor crafts ( L&t, Bharati or ABG).

Now see, there lies the problem with us. We start comparing platforms at the drop of hat. AT 109 tons, mounting a RCS is not a problem. But problem would arise after that.
Lets have a look at the class of IBs we are talking about.

First, the roles it have to perform.

Now if we look at its functions, it has to carry out SAR and disaster relief operation along with patrolling. Means you have to make it a multipurpose vessel and mounting a RCS would seriously hamper it.
How? Lets look at that aspect too.

As you could see, an RCS mount means we have to change the design of the whole craft drastically. In the 2nd pic the blue lines denote the water level of the vessel. The vessel is designed to move with a draft of 1.4 m. Mounting a RCS would mean changing this which in turn would affect its maneuverability.

So mounting a RCS is not a big deal, but the big deal is that it would have its effect on the deign of the ship which in turn would effect its performance.

But yes, the same class of boats would go in P.Tso where these RCS would play a vital role as those boats would be performing a different set of activity altogether. So the tests done were to see its feasibility in that aspect. But our moron media would mount anything anywhere.

1. Weight of RCWS including mount is between 150-250 kg. ( Similar to or twice the weight of operator and helper/spotter on the same raised deck)
2. No deck penetration required.
3. So, no change in bulkhead and so/or no change in draft of the craft/boat.
4. No change in roles as manually operated 12.7 mm gun was already carried on board ( designed along with it). So no vertical escalation is envisioned by putting in a RCWS.

Next?

Have attached two files to show whether addition of about 150-250 kg RCWS at foredeck will alter the 'draft' of 90-110 tonnes displacement interceptor craft substantially as claimed by @Chinmoy.

Members can check the change in draft of the boat when light displacement is changed to full load/ departure displacement/ load test in the thesis attached.
Also, the boat in the study is substantially smaller than the Indian Coast Guard I/C whose specifications have been attached in the second attachment ( ABG class).

I am not trying to foretell the outcome of RCWS trial with Indian Coast Guard. But, if it fails it will most likely be not related to reason/s mentioned by the said member.
