But that's not a true autoloader. True autoloaders manage ALL rounds & charge without any manual intervention.

What do you mean by that

Please explain the whole process of true auto loading step by step as you claim to know

A true autoloader will load ALL rounds and ALL charges (one after another to fire) without a single crew member needing to get off the vehicle.

What makes you think that's not the case with ATAGS ?
ie with the loaded 6 rounds and their charges

AFAIK the ATAG’s all-electric drive operates its automated mechanisms ie ammunition handling, opening and closing the breech, and ramming the round into the chamber.

Anyways no point banging our heads, in the near future we will know for sure if it is sports a true auto loader or not

Cheers , hope no misgivings

Autoloaders don't work in towed artillery that way. In towed artillery, the autoloader only loads the rounds in the magazine that has been loaded. To load all the rounds in ammunition storage automatically, you need a SPG type vehicle. Such systems are also prone to malfunction, engine shut down, fuel depletion etc. Since the mechanism of autoloader makes manual loading difficult, once the failure occurs, the guns won't be able to be fired without repair. Having higher number of moving parts is always undesirable

He meant to say that all rounds will be loaded into the magazine in automatic manner from the ammunition storage, not just fire 6 rounds and then require refill. He wants a large number of ammunition/shell to be automatically fired as in SPG/ K9 Vajra, something like a heavy machine guns with chain ammunition.

Ballistic missiles are those that travel in ballistic trajectory with little maneuvering and minimal course correction. A plane typically travels at 1 Mach speed and a BM launched from it will not have a fully known initial position. Each millisecond difference in launch time can alter the initial position. Also, the initial speed is not a constant. So, the requirements for travelling in ballistic trajectory is flouted. Hence BM can't be fired accurately by a plane

Hmmmmmm.........................

By that logic, earth rotates roughly at a speed of 1.2 Mach at its equator. Then any BM launch from near equator is sure to miss its target right? But again by same logic any cargo plane traveling at 800km/h is much more stable platform to release a BM. Isn't it so?

Any way every BM has a basic configuration to cope with parallax error during launch and every missile with INS does have its initial launch position known to its flight computer.

Rotation of the earth won't affect as everyone rotate with it. So, the relative speed is 0.

The ballistic missiles travel in parabolic path and not in a guided manner. Missiles like ATGM are not ballistic missiles. Ballistic missile motors are fired initially and only meant to power the initial momentum. If the rocket is firing during reentry or in descent path, then it is not called ballistic missile. It is just a missile, a dual pulsed missile or cruise missile

Sorry my mistake. Didn't put it the way I should have.

Rotational speed of earth is highest at its equator then its pole. So going by your logic, any missile launched from Alaska at any Chinese base in south of Indian ocean would miss it by miles. Or we could also say the reverse too. If China wants to take out the US missile sites at Alaska, they too would miss them by astronomical margin. Because near equator, speed of earth's rotation is 1670 kmph whereas in Alaska it would be 704 kmph. It means a missile launched from Southern Indian ocean would miss its target in Alaska by miles.

Isn't it so?

You are speaking of Coriolis force. Yes, that is a know issue. That is why one needs to know the location of the missile perfectly before launch. The right adjustment is done taking into consideration the difference in speed of various points. If the initial position or speed is variable as in case of air launched BM, the coriolis point will play a big role

I was not talking about Coriolis effect.

Now when adjustment could be done during surface launch, why the same can't be done during air launch? Remember that the relative velocity of the missile after being released from the cargo bay would be same as that of the plane.

First, the difference between the speeds of rotation causes Coriolis force which is an imaginary force, a mathematical construction to get a picture of the difference in the force required to reach the destination after taking the effect of Earth's rotation

The initial velocity correction can't be done in air launch as the direction of velocity will not be constant. Taking North as 0 degree, let usa say the ppane was flying in direction if 34 degree or 36 degree. This is difficult to calculate. Also, ballistic missiles are preprogrammed simple missiles that need a specific launch condition. Adjustment in launch condition may not be possible. Also, the important aspect if ballistic missile is that the direction if acceleration is upwards in parabolic path. Forward acceleration in a flat line is not done in BM. The shaurya type missiles are not BM.

Missiles can be launched from a plane. But that won't be ballistic missile. It can be precision guided missile but will not follow parabolic path

It looks like a Namibian MPV, one was under testing years ago

Google for confirmation.

You are conceptualizing the whole thing in a wrong perspective.

Whenever you release a body from a moving platform to fall free, it would have its own relative velocity. Now velocity being a vector quantity does have associated numbers like speed, direction, magnitude. At any given moment of time these numbers could be calculated or could be pre-programmed.

In case of recent Brahmos firing, you might have noticed how the missile has undergone a free fall before firing its engine. So its relative velocity at the time of fall is equal to what it was during release and its direction too was what the fighter was flying to before release. Now the firing took place because of INS, not because it has been triggered off remotely. In same manner, INS does works in a BM too. The only difference is in firing mechanism. For a ALBM, it would be pre-programmed for it. It would know at what altitude it would have to go off.

Moreover a Bomber or cargo plane would not roam off aimlessly before releasing its payload. It would have its precise location and altitude known to it. Same would go to the missile before release. So you see, there is basically no problem in releasing a BM from plane. Moreover in the video I shared, it had been shown how it fires up. Only problem is to stabilize its fall which is also shown to be taken care of.
