No DAS

And talking about 5 gen 5.5 gen 6 gen

I don't know why this development didn't get any attention in dfi yesterday
It was in news everywhere

Because we heard this exact news a few months back ..

Unpopular opnion , what if we buy drones from Iran?

How come bro
If u have bit detailed explanation
Bcoz as far as I learnt gte is different to gtg

Lets just make in simple....

You could use a 800cc petrol engine to power up the crank shaft of your car which in turn would drive your car. Here it is acting as the engine for the car.
The same 800cc engine could be used to turn the spool of a generator which in turn would produce electricity to power up a battery pack which could be used for any purpose. Even driving you car. But in that case its called a petrol genset/ generator.

In same way, if you install Kaveri as an engine in Tejas, it would power the aircraft in flight by producing thrust. Here it is acting as an engine as the thrust generated is directly responsible for moving the aircraft. But the same Kaveri would not move the propeller crankshaft of a Ship directly. It would produce electricity to power up the gear box which in turn would move the propeller. So its a Gas Turbine Generator in this case instead of a Gas Turbine Engine. This Kaveri GTG was also planned to power Indian Railway engines.

Hope you got the gist.

This isn't good right?

This isn't related to us, but Myanmar. Bangladesh poses absolutely no threat to us.

Uncle sam nhi manenge

Unpopular opinion: How about we buy drones from Turkey ?

The missile itself after being fired can climb to a higher altitude and cruise there . Just outside the seeker acquisition envelope, the missile dives down and comes to the same altitude or closer to that of the target .
All this time, the launching aircraft is communicating with the missile via a 2 way datalink and providing mid course updates. In this way, the missile will be loosing some energy but Max range will be above 300 km or in that bracket .

AIM-54 Phoenix and the Vympel R-33 and R-37 works in this principle. The Phoenix first climes up and then flies at a stratospheric altitude and then dives down on its prey.

Every BVRAAM is launched at a higher angle of attack. Its not unique to a couple of missiles. But the higher the angle of launch, the higher would be the induced drag. So the preferred launch method is to launch from a higher altitude then the target aircraft to attain maximum range.

Now it has been clearly mentioned in the brochure that if the launch altitude is 20km, then only its range would be 340 km. So in all practical sense, its range would be somewhere in 210-230 km bracket.

Even no nose cone.

So this is a huge development and a large step closer to indigenization of our vessels

A nice step towards KMGT I would say if even it is based on it.

Nope, this is much smaller meant for supplying hotel loads. Remember it has to replace a 1MW diesel generator, so dimensions would be largely similar.

We are looking at something like this.

The GT would be even smaller, smaller than HTFE 25

I too agree that if we use KMGT, it would be highly downrated version. 12 MW against 1.2 MW don't sit right in equation.
But if industry could take it up under ToT, we could expect something based on KMGT.

I think @porky_kicker replied on this. But I am unable to view the reply.

Nope.

Not all bvraam or most bvraam aren't launched with the nose titled up at high alpha coz unlike wvraam which launches directly from the rails, most bvraam gets ejected from the pylon, falls for some distance and then the solid motor fires. So irrespective of what is your plane's alpha, the missile will be shooting off level and straight.

There will be induced drag and that's why I said the range will be reduced from 340 km but it will still be 300ish km .

Look up how the Phoenix missile worked. The Soviets modelled the R-33 to work in a similar fashion. The missile always climbed up to a higher alt irrespective of the launch altitude of the missile. In this way the missile could travel a greater distance in medium of lesser density .

JUST IN: Indian MoD approves push to acquire 400,000 *indigenous* Close Quarter Battle Carbines for the Indian Army. The latest in the meandering Indian quest for CQB carbines. via Livefist

Looks like it will be SSSDef or AstrDef

But do Kalyani-Thales, Kalyani-ARDE, Caracal-Indian etc qualify as "indigenous". @Tactical Doge @Johny_Baba

I am not suggesting that SSSDef or AstrDef have all sub components as "made in India"

Check the small arms thread apparently SSS defence isn't that good if their specs that have been posted are real probably not since they were not official

Nothing new this is well known among those who have been following mk1a program

I believe it is first 20 and not 19.
For 21st aircraft we shall use Uttam AESA.
