Only a 4% increase from last year's budget of 5.94L Cr. Given we have ~5-6% inflation and increasing dollar price we have essentially reduced our defence budget

Interim budget. This is going to increase anyway.

How much time till the deal is done and we have our first mq9

Deal?

Now there would be negotiation before making any deal.

 

[Anupu]

So had some free time and did some digging. This is the supposed satcom on Tapas a mechanically steered antenna in an era where even Starlink provides an AESA antenna for Satcom. Bhai log kya phook rahe hai yahan. I won't be surprised if data transfer rates are shit.

I was asking for like an overall estimated timeline

 

[Chinmoy]

what if it isnt an exercise ?

In that case too, this jugaad would be more practical then this.

2nd half of 2026 in all probability.

And what's wrong in that?

MQ9

Happy?

 

[Anupu]

And what's wrong in that?

On digging deeper surprisingly nothing, almost everyone uses but apparently, there is a difference in KU band and Xband for transfer rates (X band gives faster data transfer rates). This is such a low-hanging fruit though.

Yeah already looked it up.

Happiness lies in HD quality and additional details.

????

X band operates in 8 GHz to 12 GHz whereas Ku band operates in 12 GHz to 18GHz. Means Ku band uses a much wide spectrum then X band which makes it much more resilient.

Ku band supports a much higher throughput then X band which is what we require for data communication. Higher throughput means high data rate which means much better real time data reception from and to the drone.

So instead of X band, Ku band is used for SATCOM in all modern drones.

Meanwhile MQ-9B's SATCOM terminal

Yes, you are right, it's more like they are using a wide-band antenna which can operate in both Ku and X bands allowing for faster data transfer rates. Also, Ku band can give almost 10mbps easily making it viable for surveillance drones. I learned some new things today.

Seems like an old pic

I believe that multi spectrum decoys might be the latest addition inside that balloon.

Rudram-II in all its glory.

Range-300-330 km when launched from altitude.
Has a 155 kg warhead.
There are two variants.Anti radiation with PHH and mmW seeker and ground attack variant with IIR seeker.

What is the difference in the roles of Rudram II and Brahmos ALCM when the former is used for ground attack?

cheaper missile basically

I just want to understand, how does someone in IA posts this Normandy type landing video and think that Indian public truly see the greatness of IA and it's MOderNiZatioN. Do they really think that we are utter fools and can't see what's going on.
IAF and IN are generations ahead of IA in terms of modernisation. And the funny thing is apparently Ground forces are the easiest to modernised as it's projects are relatively less technologically challenging and less expensive than those of naval and Air forces.
Guys sorry but if this bullshittery continues on, I'll be betting my money on PLA than IA in case of a conflict.

TBH that landing craft reminded me of a tipical *SRTC bus.
