I was at CVRDE chennai 2 weeks back, saw a turret that afaik doesn't belong to arjun, t90s or t72s. I will describe it once I get a closer look the next time I'll be visiting.

This study is being carried out to replace RBU. You are just saying the same thing on loop.

ASROC is a good anti sub weapon, but RBU is just like a sidearm an infantry man carries along with his main arm. RBU has seen its prime and is getting obsolete now. So we need something to replace it. A anti sub/torpedo rocket is much more cheaper then a onboard torpedo which again is much cheaper then a anti sub missile.

Replacing RBU with another unguided rocket launcher, seriously dude? Bolt action rifles were replaced by Assault rifles, now next gen upgrade in Assault rifles will be FCR sights and fused thermal sights. What are you going to upgrade exactly beside range which in itself is not really an upgrade coz range is just too low, anyway how about 90R Rocket which was a real upgrade to RGB 60 rockets of RBU, no guidance upgrade? Increasing the range means increasing the size means you can only squeeze out so much range perhaps max of 10kms, which already takes so much place. I hope you didn't missed the news of Slava class cruiser ammo below deck blowing up, ammo of RBU below deck is not enclosed in protective coverings.
At best the best logical upgrade could be a guided rocket like 90R with range extension fired from current RBU launchers to extend their usage and life.
How does one put a red line where capability is paramount to cost and only after crossing that capability red line can the cost be considered?? In this context are RBU really COST-CAPABILITY effective? For example time of 3rd gen fighters have really gone and you can't expect IAF to get more 3rd gen fighters as they are really cheap, i hope you get the point.
And you haven't yet told where are you planning these new developed launchers????? And I don't think IN will be keen to strip away their current RBU launchers.
If everything sounds loop to you then i am sorry to say that you haven't yet produced any logical counter argument and your statement about RBU is no more than euphemism.

Kaveri will not go into Tejas anytime soon, which is a single engine fighter. Not until it successfuly demonstrates few 1000 hours in a flying testbed with another backup engine over the course of next 5-6 years. If it cannot match the thrust to weight ratio of Tejas, IAF will not accept it over f404 that has very high uptimes with very minimal maintenance

Yes but that means India would be a slave to US in terms of strategic geopolitical considerations. That is not something that the GoI would tolerate so IAF needs to figure out a way to get around that.

Is it more like the arjun turrets or the russian t series ones?

You have written an essay which is totally irrelevant with the development and the news.

RGB-60 has been indigenized back in 2010. In 2018 DRDO came up with a new ER-ASR system to be fired from same RBU-6000. Now since the RBU-6000 launcher is a huge bulky one, DRDO and L&T has joined hands to design a different launcher based on Pinaka. No one is developing a Pinaka rocket based ASR. It would fire the same ER-ASR or even 90R. (https://www.deagel.com/Defensive Weapons/RPK-8/a001949)

On other hand, don't get fooled by the homing head of 90R.

Its guidance is as same as RGB-60, which is ship based SONAR.

wait why are they testing the lca mark 1 now?

Air frame Certification. Without this, don't expect orders for Tejas.

What do integrated electric propulsion do basically

Its basically combining electric power from two different source for a single purpose. In this case driving the propeller shaft of ship.

According to various sources From Indian Media, It's a success. The Akash missile was tested at the Pokaran field firing range in Jaisalmer on last Wednesday (27th of April 2022). Please refer to these sources:-

What do integrated electric propulsion do basically

Integrated electric propulsion (IEP) is an arrangement of marine propulsion systems in which gas turbines or diesel generators or both generate electricity which is then used to power electric motors that are responsible to move propellers.

IEP replaces traditional propulsion system like COGAG for ships which eliminates the need for clutches and reduces or eliminates the need for gearboxes by using electrical transmission rather than mechanical transmission of energy. It provides more control and can sometimes be even more energy efficient.

Combined gas turbine and gas turbine (COGAG) is a type of traditional propulsion system for ships using two gas turbines connected to a single propeller shaft. A gearbox and clutches allow either of the turbines to drive the shaft or both of them combined. It is mainly used in destroyers and high performance ships.

Combined diesel and gas (CODAG) is a type of traditional propulsion system for ships that need a maximum speed that is considerably faster than their cruise speed, particularly warships like modern frigates or corvettes.

-------------------------------------------------------------------------------------------------------
While CODAG and COGAG use mechanical energy of the engine to drive the propeller, IEP converts mechanical energy of the engines to electric energy and then drives the propeller using electric meter.
This provides better control and efficiency.

Jaisalmer | Akash missile is being tested these days at the Pokaran field firing range of Jaisalmer district of Rajasthan, which has witnessed many successful tests. The prime version of the Akash missile is undergoing successful trials at the range. This missile can hit up to 30 km in the sky. It can go up to 60 km in one go. The biggest feature of this missile is that this missile can also be controlled in the air and can also target from drones to fighter jets through its own sensors. Akash Prime directly competes with the US-made Patriot missile system. Its target is better than the Patriot. The missile successfully destroyed the target during the test on Wednesday. DRDO since last three days

And testing is being done under the supervision of army officers. New advanced features have been added to the Akash Prime surface-to-air missile. Along with this, its firepower is also being tested in the scorching heat. Akash missile is the first air-to-air missile made in India. They can be fired from any vehicle or permanent place on the ground. Akash Prime has become the third important missile of this class. Akash missiles are developed by DRDO and manufactured by Bharat Dynamics Limited. The responsibility of manufacturing its surveillance, radar, command center and launcher is with Bharat Electronics, Tata Power Strategic Engineering Division and
