I am unable to determine from my naked eye if the waterline is higher, but not sure if 4 BMs will cause a visible change to a sub's waterline mark. You're probably right. 17t x 4 = 68t. Arihant's displacement when surfaced is apparently 6000t. I'll assume you are right. Does it even look like the s...

It would appear like there is no 'greenfield' assembly line for the LCA, existing buildings/hangars have been repurposed for it. Not true. Plenty of photos in AK's article below.

Indranil, is that correct - up to 80 pulse motors on one rocket? Or should it be 8?

Thank you, brar ji.

Brar ji, I was going to thank you at several points but each time I thought I'd wait in case you were to add more text and it helped - because you added useful information until your very last edit: The entire point of a Mid-Course guidance through data-link is to make sure that the missile is at a ...

Radar guided BVRAAMs need to switch their radars on for the end game.. The technology where an AWACS allows a silent shoot all the way hasn't come online yet. So until then, if a fighter radar can't pick up the stealth target at useful range, how would that little thing in mijjiles nose cone stand ...

PratikDas

If we can't be assured of seeing first, is there a point to all the investment? Should the money instead be invested in 1000s of BVRAAMs which invade enemy airspace like locusts? If you can't see, what will you fire your BVRAAMs towards? I'll fire them toward what my AWACS sees, which will be much ...

PratikDas

All fighters, including the light ones will require stealth features ( seeing first is critical ), high TWR (which is what drives supercruise) and networking capability. This has me worried. We can invest a lot in stealth but how would we know if our stealth is better than Chinese stealth? RCS numb...

To fit 8 Warhead into K-15 of diameter 0.74 m, each Warhead must have a diameter less than 22.9 cm. :) Perhaps we can do that. I have no reference.

There must have been a mistake. I really don't see how a missile designed to fit in 3 units to one missile tube of the Arihant can have 8 warheads. They can have 3*300kt FBF/BF or 8*20kt fission RV ,depends on the size/weight of physics package and rv and that's how major power increase their uploa...
