Why does shtora take away ERA protection on the T-90, while on the T-80U shtora is placed on top of ERA and doesnt replace it?
That is at the thickest part of the turret armour, plus the emitter uses layers of ceramic plates that are heated (note the extensive cooling fins around it).
If the enemy want to hit a metal box in front of the thickest armour on the tank who cares... how is that a weakness?
Shtora dazzelrs allegedly need a long time to be pointed at a missile to spoof it
Which just proves he does not know how they work and does not know what he is talking about.
Shtora dazzlers are invisible to the naked eye and work against the Giononmeters built in the the wests SCLOS ATGMs. A gionometer is a device... an optical port on a missile launcher like Milan or TOW or HOT that tracks an IR flare or beacon on the tail of the outgoing missile and its job is to calculate the deviation of the missile from the point of aim so the system can calculate a manouver for the missile to move back into its centre of aim.
The Shtora dazzlers... as their name implies does not spoof anything... it sends out an intense IR signal so the the tiny IR beacon from the outgoing missile is lost in the wall of IR light coming from the two dazzlers... when the ATGM launcher cannot tell where the missile is it does not know what command signals to send and it will generally fly straight into the ground or veer off and miss by an enormous margin.
Shtora would not work on Kornet because the launcher does not track the missile, the missile looks back at the launcher and finds its place within the laser field directed at the target and it manouvers itself into the centre of the beam.
The T-90 is far too slow(Irrelevant, strategic mobility is more important than tactical)
No commander's thermals
Western tanks are too heavy and too slow and way too expensive... and in the case of the Abrams only the US could afford the fuel burn rate.
The TOW2, Hellfire and Spike are resistant to the shtora and they're NATO's main ATGMs.
No they aren't... because Shtora includes an entire suite that includes smoke grenades that are still effective against all of those systems... and it is automatic.
Can the dazzlers scramble the tank's IR signature, making it difficult for thermals to spot it?
Not really. In a thermal imager the dazzlers would look light bright spotlights turned on, but not overwhelmingly so. From an IR tracking system looking for a small flare it will look like trying to see a candle flame being held up with a light house light lit behind it... the flare would not be visible.
Through a thermal imager you would probably see both.
A better question would be what western tank does better... Kornet... Vikhr... Khrisantema... Ataka... and now LMUR and Hermes... their new vehicles have a system called Quarry that is a laser based anti optics system...
Plus T-90 was developed and deployed in the 1990s during several economic collapses.... but even now they are funding their military and introducing new military kit and equipment that is brand new and state of the art in some cases with no western equivalents, while the west is abandoning allies and cutting procurement numbers so they can spend more on nukes... which sounds like an admission of defeat to me...
But lets give them the benefit of the doubt... the original T-90s lacked a separate commanders thermal sight, the gunner had one but the commander didn't... SHTORA Dazzlers only had a limited period of effective use because as ATGM makers learned how they worked they would adapt their systems so they were no longer effective... SHTORA is so much more than the two dazzlers of course but lets carry on... their position is ideal for their role but does leave weak spots on the tanks heaviest armour locations and we know western penetration performance claims were bullshit for all their missiles and weapons. The T-90 is not the fastest tank, but its power to weight ratio is pretty good having a 1,000hp tank that is 20 tons lighter than most western tanks.
Is that sufficient to call them useless junk that suck?
Sounds like a child describing an ice cream flavour they don't much care for...
Still, the T-90 was developed and put into service during a very difficult time for Russia when there was almost no funding and several economic collapses, yet they made some and put them in service and these days are upgrading all their T-90s to an improved T-90AM level that eliminates many of the old problems like the thermal sights and the dazzlers have been replaced presumably by a system called Quarry that is a laser based anti optics suppression system.
Also they are introducing its replacement in the form of the T-14... a brand new from the ground up scratch built new tank... as well as introducing stealth fighters and stealth bombers and new attack helicopters and infantry equipment second to none... their training seems excellent and their airdefence network is the strongest in the world by far... but lets compare with the mighty west... Britain is spending billions on Trident and can't afford new tanks or F-35s... it seems they have realised they can't win a conventional war and are putting their eggs into the nuclear missile basket.
The British tank... 1916 to the early 2020s... RIP.
No wonder his panties are in a bunch.
