Thank you, Sachin, Dinesh & Indranil for the informative responses. All points make sense.

The way to go would be like the T-14, with an unmanned, lightly armored turret to save costs, but tons of electronics to ensure situational awareness. Taking it one step further, build a NAMICA with 40 LAHAT (13 kg each for 6 km range), INVAR (17 kg each for 4 km range), Spike and MPATGM (14 kg eac...

+ does anyone have the definitive dimensions of the lifts? The lifts can currently carry the MiG-29K and the Tejas Mk1. Boeing has confirmed that the F-18 will fit on the lifts. The Rafale M cannot fit on the lifts. Dassault is suggesting detachable wingtips. F-35B and F-35C will not fit either. I ...

I have a nagging suspicion that the length of time it takes to build a ship in India is a function of budget and not the industrial capacity of the yard. So if the budget is improved and made available on a timely basis the ship itself can be finished in 5 to 6 years. Absolutely true. Money is rele...

Question for Helicopter Gurus and HAL Folks - Why do we de-rate engines of our helicopters? I understand HAL Cheetah has de-rated engines. Seeing the HAL Brochure above, I see the LCH has slightly de-rated engines. What are the benefits of using de-rated engines? Why not use peak power of the engines?

I would suspect slight maneuverability degradation with the legion pod but that is entirely due to the USAFs requirements for the pod not only to carry the sensor but also a self contained computer and room for a pod to pod dedicated data link. The tiger eyes is much more compact though it has the ...

You're very wrong regarding your speculation of "ad-hoc fashion" Litening for A2A tracking is a very well established capability for two decades. Incase you missed reading it earlier, the Litening AT pod referred in the A-10 datasheet is a second generation pod fielded 2003. It clearly me...

If that was the case, it is peculiar why IA assumed a 4 crew, 120MM Arjun would be equal to Centurion. A cursory glance on the weight of M1A1, Leo, Chally would tell you what a 4 crewed modern tank would weigh! if you want to replace Centurion's with Chally, you are getting a 60 ton tank! Even if T...

The most peculiar question, I have on the Arjun saga is how was a GSQR for 4 men tank issued, when our primary tank was 3 men, with autoloader T72! Then complains about how it turned out be "overweight"! The primary tank was 4 man Centurion and Vijayanta. The Vijayanta was then the most n...

Arguably the IAC-1 has had a much smoother journey in the sense that it isn’t at the bleeding edge of tech, all the delays just seem to have been self-imposed. In my earlier post, I mentioned that IAC-1 was first in class. Just like a first in class fighter like Tejas requires immense lab based mod...

Who are these two credible folks? One of them is Grp Cpt HVT. Interesting. I didnt find any reference to the IR program in the request for grants for funding, hence asked.

This is an utterly beautiful and cutting edge ship but the time taken to build her and get her into service is utterly indefensible,2018 was a decent target, I don’t understand how they slipped by FIVE years.

This is most likely the case. Using a podded system for a2a work doesn't seem to be the most optimal solution, esp. when you have a powerful irst slaved to your hmd already. Yes, precisely. You can use them in specific cases for a multi-target function but that's not exactly its primary role for ai...

MICA's tvc will help in making quick turns after initial launch when the motor is still burning but is useless in terminal phase. Not sure if the terminal maneuverability of the MICA will be a whole lot better than an AMRAAM etc. MICA has both bank to turn and skid to turn capabilities. The motor i...

tsarkar I am sure the IA has thought of that.. I hope so. Reading the INSAS story on twitter made me realize the move to 5.56 was not based on field experience but a HQ decision based on theories of flatter trajectory and a desire to follow NATO.

Doesn't direct impingement lead to more heating and require more cleaning for fouling? Both cases are frequent in sustained combat.

For example, Jaffna University

After all this do we really need the AK203 production line? No. No one pays royalty for AK design. Even USD 200. I would rather go with Munger made AK's that are quite reliable. The makers are all ex IA/OFB fitters. Both Trichy and SSS AK designs use milled receivers. Doesn't it affect cost of acqu...

Mica has the best maneuverability among all BVRAAM. It sacrifices range for maneuverability.

Good design thinking as simple range advantage isnt effective given how Su-30MKI evaded the AMRAAMs.

I am guessing IAF is giving two hoots to the French tantrum that no French missile with non French radar.

tsarkar

Can the Litening pods also be used for detecting aerial targets? Yes. The IAF has been using Litening as a FLIR for over two decades. It works better than the Su-30MKI or MiG-29 IRST. A big hint is the Su-30MKI in Red Flag Exercises carrying ACMI pods for Air to Air combat and Litening pod on the i...

Would it have been a wise decision to build aircraft with lossy radomes or no radomes? And send them to combat like that?
