DRDO and PSU's

It's impossible to have 360° coverage with just one radar, no matter how much gymnastics you do with swash plates.

Even if you theoretically traverse your swash plate ±90° then also you'll have just 270° of coverage [2x (45° electronic beem steering + 90° mechanical swash plate traversing)]. And if you mechanically traverse beyond 90° then the fuselage of the fighter itself would start blocking your radar.
Sorry for the late reply but I meant the rotation not coverage. I Should've been more clear.

But my main point was why would they go for a swivel mechanism rather than a swashplate. What are the upsides ?
 
I have a question for fellow membran. Why DRDO doesn't have a CCM program yet ? Why should India (a missile powerhouse) should pay royalty to MBDA for a product we can easily develop. I read a long time ago of a astra variant with ir seeker was in the works but no CCM per se. BTW such a vulgar name for a missile 'ASRAAM'

Priorities. BVR was first priority now that they are maturing medium range missiles will come with ir guidance.
 
Question is what will be the final weight of the submarine. Arihant is 6k to 7k tonne sub. Current diesel subs were 3K tonne. Loves to see this version how DRDO reducing the overall dimensions.

3k ton is design goal. But requirement of VLS cells and more batteries than current gen subs will mean bigger dimensions.

Latest South Korean sub is touching 3800 ton displacement so I guess ours should be similar.

4000 ton displacement is my estimate given the range and endurance we need.

What exactly is a swash plate!? It's a swivel mechanism that has 2 DoF; one in traverse and the other in elevation. No enemy plane is coming at you from exosphere nor from below the ground; so even if your field of view is constricted to a mere 90° cone then also there won't be much of a compromise. Having coverage in traverse is what matters because usually it's the flanks from where a bogie comes in.

So it's better to save some cost and complexity instead of having marginal improvements.

> When WVR missiles were the hottest thing in the market (late 90s) we were in our infancy of air-defence missile with Akash still working on improving its RF seeker
> As we started getting matured in both missile propulsion and seeker (both RF and the IIR seeker, developed for Nag ultimately culminated into a family of seeker used everything from VSHORAD to KKVs) the trend of WVR missiles started to fade away as now and even in future almost all of the engagements will happen in BVR
> Hence BVR, not WVR
> Only in the last two years we've started to see the resurgence in the use of WVR missiles to shoot down enemy cruise missile and loitering munitions

tl:dr; we already had all the components of a WVR missiles but the actual need for it in combat was not enough to justify full scale R&D. But now as dynamics have changed, we might see one on couple of years.
BTW such a vulgar name for a missile 'ASRAAM'
What's vulger in "AIM-132 Advanced Short Range Air to Air Missile"!?
I think you're complaining on a wrong platform, take your grievance to the person because of whom you're perceiving it to be vulgar.
 
All 155/39, 155/45, 155/52 Wheeled SPH weighs around 25-30 tonnes. Only exception is Caesar from France which weighs 17 tonnes. But even France is upgrading the armour which results in 25+ tonnes.

BF ones is on par with all contemporary systems.





This submarine is based on Arihant design with all Arihant Vendor ecosystem will come into picture. So we will have VLS etc.

Question is what will be the final weight of the submarine. Arihant is 6k to 7k tonne sub. Current diesel subs were 3K tonne. Loves to see this version how DRDO reducing the overall dimensions.

Again should never went for P75I, when we are sitting on Arihant sub design.
155/39 Kalyani MARG is 18T

NG-CCM is the next project for DRDO. It will be our WVR missile. Till then BDL have License to produce ASRAAM (AIM-132). We can brought them from BDL and also BDL can sell them to NATO bois. Win Win for both BDL and IAF.

Putting the VLS should increase the overall size of the Sub. Loves to see how DRDO sizing down the Hull from 6k to 4k tonne. Most probably we will go with Brahmos UVLS. May be 16 or if Nirbhay based missile is ready. Then we have cheaper alternative also.
 
Do you mean degree of freedom ?

There, marginal improvements 👍
but the actual need for it in combat was not enough to justify full scale R&D
Not sure if I fully agree with this take but ok 👍

"Grievance" ?

It was an observation rather (maybe a frivolous one). It wasn't a cheapshot at any member's personal life 🏳️‍🌈.

I sincerely apologise if I have offended anyone here. It wasn't my intent.

Are you sure NG-CCM is a different project than ASRAAM domestic production ? If so this makes perfect sense

NG-CCM will be an Astra based missile using IIR. May be further refinement.

ASRAAM production happens whether we require or not. NATO after Ukraine war saw the constraint in weapons production. Western countries cannot produce required quantities. So to avoid this, license production is going with Manufacturing countries like us. BDL is getting the contract left, right and centre. OEM business is heating up, Adani is another Big OEM with IAI, DRDO as partners.

Even Australia is trying to setup few manufacturing plants for weapons production.

NG-CCM is program name for adopting ASRAAM iirc.

There seems contradicting reports regarding NG-CCM. DRDO developing an NG-CCM. Nothing to do with ASRAAM.

IAF inducts ASRAAM as NG-CCM.

So the weapon will be called as NG-CCM. So the product from DRDO will receive an name.
