The SLS system seems to be geared towards maximum of Shaurya launch. 7 tonne and 10 m long corresponds to the K-15 (6.2 tonne and 10 m long). Hope they can also use it from brahmos series and other SAM's.

Why use Brahmos or SAM for this rectangular cannister for 7 ton Missile? Brahmos are already inside the VLS

 

[Kalki_2018]

So the floating test range will only do K-15? What about K-4/5 etc.

SAM systems are much smaller and this will be unnecessarily bulky. These are just naval version if TEL. Brahmos can be a good contender. Barak-8 weighs less than 400kg and is way short whereas Brahmos weighs 3tons and is longer.

The biggest advantage I see is that these can be reloaded easily and they can be camouflaged as a civilian container and launched from cargo ships

For long range testing of

1. AShMs eg cruise missiles / hybrid ballistic cum cruise missiles.
2. MIRVs
3. IRBMs/ICBMs where the missiles will be fired from land.
4. Long range SAMs
5. ABM interceptors
6. Tactical manuvering ballistic missiles
7. SLBMs fired from pontoons / submarines

Etc
Etc

India does not have the required large continous desolate and unhabited landmass to conduct the required tests in full flight envelope with an instrumented and telemetry capability .

So floating test range gives you the flexibility to stretch yours legs as much as you want , you only need to position your tracking ships at the appropriate distance which could be near the Antarctic if the need be.

SLS is a part of the floating test range and for the time being will come into play when it tests ABM interceptors for interception of hostile missiles at 5000km range. Present interceptors can target hostile missiles fired at 2000km range, this 2000km range interception is presently stimulated by 300km range Prithvi missiles. This does not allow full real world stimulation of the 2000km range interception scenio as one would like to. It is enough but still not enough.

In future long range missiles will be fired from land at ranges of 5000km or so and since the missiles will fly their full range they will be able to perform the required anti ABM manuvers and deploy decoys etc and the SLS equipped ships located at appropriate distance far into the ocean will fire the interceptors to destroy them. Thus drdo will be able to stimulate and validate in real time the capability of the indian ABM against a hostile missile with all its offensive and defensive capabilities at play.

No... All the K family missile would be of same length with varying girth. So K15 K4 K5 would be 10 m each and may be K6 would be somewhat longer, but not much.

 

[Kalki_2018]

Last I checked K-5 was to be 12 m long only K-4 is 10 m in length.

 

[Chinmoy]

I believe you are talking about K6 which is speculated to be of 12 m length. As far as open source goes, K5 is also speculated to be of 10 m in length as it has been designed to fire from Arihant class subs which have a beam of 11m.

Yes SJha is wrong CVRDE is yet to find partners(since 2014), they issued EoI again in 2017. Maybe no one has shown interest b'cuz army yet to order Arjun mk-2. That's why DRDO was requesting army to do so.

The powerpack of 1800HP appears to be bit extreme for the size limitations. By the way, where did you learn that the project has been extended to 2022?

Making tanks is not a hard thing. It is just about the fund allocations. India prefers to allocate funds to more pressing things that take longer durations of time like Naval propulsion, Tejas, Kaveri engine and hence cuts the funds from simpler items which could be done any time in short notice. As Doval said, tanks have now become less important. Airpower and hence Tejas plane is more important

@Sancho look at 8:30 about GaN radar research done by DRDO. So much for your ranting about lack of GaN foundry

For that one need no confirmation, their are several papers on GaN Avilsble in the defence science general

@Sancho regularly used to irritate about India not having GaN research. So, I just got an opportunity to point it out to him with more simple and explicit evidence

Their are various people in IDF who suggest India shouldn't take the project AMCA, because we lack rnd, I suggest them to search anything related aerospace quoting drdo, they will get several papers regarding that. Vision is the difference.

@Sancho are u a Indian or a German bro.
You're inferiority complex suggests that you are the same breed as Dhurv Rathee, sucking on Mata Merkels feet for cheap euros.

He said upto 40W S band modules are completed but 100-110W S band modules are needed for ground based radar. He then says that 10-12W X band radar for fighter aircrafts are already ready and in production.

I am not sure if it is GaAs or GaN module. He may have been speaking generically on the AESA radar module and might have spoken of GaAs. If he was speaking of GaN, then the question arises as to whether UTTAM radar is GaN

Acc to latest paper, the breakdown voltage they reached is 150V and operating voltage to 50V, with the addition of field plate in S band for 1mm gate width HEMT
