Just to add, it's now really easy to build a cheap 360degree computer vision system based on commercial technology, which can instantly detect, classify and launch against a helicopter, because it is silhouetted against a clear sky. I imagine they will be mounted on pretty much every vehicle, and will nullify the advantage of surprise/mobility/hiding which the helicopter relies upon.
one of the Key features modern choppers use is low level attack often in and around Terrain. They are not always nice and clearly visible. The Addition of systems like Millimeter band Radar also comes in as those can see well beyond the visual range and allow long range attack with ATGM from a long range pick of the Shorad and then start taking Tanks
. Also as to Shorad being "Cheap" that depends on a lot of factors but a good Shorad system can cost just as much as the Tanks that it supports in example the K30 costs 5.7 million US well the 2K22 Tunguska will cost 16 million US.
And if armies start to deploy fleets of accompanying airborne drones (which also have computer vision systems), where does that leave the attack helicopter?
Attack choppers also have Countermeasures and Vision systems already.
The Attack chopper still has some advantages, first it's more nimble. Although Drones Theoretically should be more agile by not having squishy humans aboard. There Communications rely on maintaining alignment with satellites to keep feeding data to there operators. this limits them as if they loose contact they go dumb as a post. It's like fighting the Silence from Dr. Who. you Start the fight but the moment you loose sight you forget when you were doing. Because AI is not at the level to continue a maneuver with out making the Drone Very expensive. Also today Drone Choppers are still in the light weight range where manned Aircraft tend to have the extra weight capacity/
Does that mean attack helicopters become killers of drones and other helicopters, and it is the drones that perform close air support?
Attack Choppers have the Flex to do all of the above and then some. The Chopper gunner can remote the Drones and coordinate the attack well standing off and using it's long range weapons to assist in the kill.
And Shorad systems are being oriented to try and cover more for Drone attacks.
Talking heads on Chinese TV with military background like to say reliability of equipments is paramount for the PLA.
That's standard for every military. It has to work in all possible environments and situations.
Any new equipment should not have more than 30% new components
What justifies "new" and What justifies "old" I mean The Autoloader in the Type 99 is a Carousel like that in the Russian T90, T80,T72 but it's not the Exact same model. it's not that they took a T72 ripped it open and pulled the Autoloader and dropped it in the Type 98 hull. I mean saying that only 30% is new does that mean that it's actually 70% old tank?
The way that is phrased is so wide you can drive a Super tanker through it sideways. I mean the way that is phrased could be interpreted a million different ways.
Obviously the Type 99 is a new tank it's not a Type 88 hull with a new turret.
When I say Conservative What I mean is that the PLA studied existing Tanks took concepts that Worked and designed a Tank around those. but that's generally how all nations design armored vehicles to a wide degree. All vehicles quote really. It's a very rare thing when someone tries to totally reinvent the Wheel. And Even Tanks like the Type 10 and K2 are based on existing and proven technologies.
but from a Doctrinal perspective the Type 99 is a very conservative Eastern Block Tank of the Third Generation. They didn't try a 152mm gun or try a unmanned turret or cram a laser gun and VLS cell on the Bustle. Rather they started with a proven chassis layout, and a verity of systems inspired by proven quantities. Then aim to upgrade the tank incrementally to deal with the next steps up.
