This cartridge was the primary anti-tank weapon used by US Army tanks during Desert Storm. Weight: 20.9kg, Length: 984mm, Propellant: JA 19 Perf (7.9kg) creating a chamber pressure of 5,600 bar. The Projectile length: 780mm. Weight: 9kg. Penetrator is made of depleted uranium. length: 684mm. Diameter: 22mm. Weight: 4.6kg. Muzzle velocity: 1,575m/sec. Target range: 3,000 mw
1. Smoke/heat

3. Sound
How do you know?
Let me break it down for you;
1. Smoke/heat
2. Impact
3. Sound
Infrared detectors monitor not only heat signatures from booster/motor heat trails of air launched weapons, but also cannon fire.
BIG heat bloom, LOTS of hot smoke, stuff like that.
see the bolded part? double arena`s ability to react
arena cannot detect launches out to 2km`s - if it could then it would be going off all the time; same as trophy as well - it is not designed to counter long rod KE rounds
by the time smoke has registered the round has allready hit , impact - the round has hit , sound the KE round has hit , heat (IR energy) you have less than 1 second to detect the bloom from the end of the 120mm gun , 2 km`s away to react to the incoming - how much less than that second? - the thermal expansion continues well after the round has hit so in the flight time your only looking at a thermal (IR) image a few meters accross - 2 km`s away.
all that smoke and flash you see in videos is after the event -what ever the tank is shooting at is either dead or , well dead before the pyrotechnics.
i pose you this - if arena is so `good` why do russia etc have K5 heavy?
I know because the average KE penetrator flies a distance greater than the ARENA's engagement range in less time than the ARENA can react.
And were forgetting something else as well, thats just DETECTION time. Engagement time is a stated .2 to .4 seconds, and at an average .3 seconds the penetrator will travel 300 meters. THATS how I know. Its simply not fast enough. Its sensors do not reach outside 50m simply because its weapon system can't reach that far.
Seeing as how KE penetrators travel quite a few times the speed of sound, number 3 is a dead point.
Impact? I must be missing something. How would impact help the ARENA block KE penetrators? Does it proceed to shoot the KE penetrators after they have already hit? I know I'm missing something.
When the system is triggered, a warning signal is activated, to warn infantrymen that may be following the tank to open some distance or take cover.
Smoke/heat...while this one might be valid I would like to see a source for the claim that ARENA's sensors reach out further than 50m.
Of course all of the above points are still moot seeing as how the ARENA is still not designed to engage projectiles as fast as a KE penetrator
While Arena-E provides an effective protection against many types of anti-tank threats, from RPGs to fast missiles such as Hellfire and TOW, it cannot defeat fast missiles (such as HVM) and tank projectiles, such as HEAT shaped charge projectiles and APFSDS penetrators. Different countermeasures are being examined to defeat these threats

KBM themselevs state ARENA is designed to counter ATGM such as TOW and Grenade type weapons like the RPG-7 - link as above.
ARENA cannot react to a KE long rod - the published sensor range is 50m - from your link(s); further in 0.4 seconds the round will have traveled 650 meters arena will not fire till after the round has hit.
ERA
ERA does not pre guess anything , does not pre detonate or any such rubbish - it ia just fast explosive;
you do know the difference between fast and slow explosives yes? wave form paterning and volume?
the fast exploives have an energy expansion rate in excess of 3000 m/sec - but over a small area. incoming at 1500 m/sec meets outgoing at 3000 m/sec when done properly the long rod will SHEER against the outgoing blast.
but its not perfect - the self sharpening of DU will ofc help.
please will you stop with the silly motion that ARENA can intercept a KE log rod - it cannot and will not - the sensor suite *might* detect the heat bloom from the 120mm gun - but that as much as it`ll get –
“The ARENA is designed to defeat projectiles with a speed of 70-700m/s. A KE penetrator is significantly faster. “
That’s correct. Projectile traveling up to 700m/s are destroyed, and while KE projectiles are not destroyed, their trajectory is affected which puts them off center, thus decreasing their penetrating ability.
at 0.4 seconds from the target the KE round is 650 meters away
at 25 meters ythe system willl have
0.01 seconds to react - not a chance .ever.
arena simply cannot react fast enough - your making out the system can do something which frankly - the laws of phsysic says it can`t –
RADAR - is radioa waves , which travel at a set frequency vs distance –
`speed of light` - great - thats light - by the time you see or detect the flash - the round is 50% of the way towards you.
arena is a great system for dealing with ATGM and mortar and grenades - but is useless against hyersonic round - 1750 m/sec is just above MACH 5.
please understand that arena (or trophy) will not react to a KE long rod - it is NOT designed to.
btw im waiting on an email from the maker (as i did when i emailed eurojet about the EJ2000 in gripen) - and quite frankly they will laugh at the notion it can intercept a KE round.

the israeli iron fist APS is being developed to intercept KE rods
KE penetrators do not emit a massive muzzle flash all along their flight path. I don't doubt that the T-95 can detect when a tank has fired, what I doubt is that it can detect and track the penetrator when its fired, and so far all evidence seems to point away from that, including the source that happens to specifically state that the ARENA cannot defeat KE penetrators.
So far I can find zero information on the T-95s radar, and I have a LOT of trouble believing that a small, tank radar can track a tiny KE penetrator any more than it can track a bird.
And NO, the T-95 is almost NEVER going to have the ridiculous army of sensors and radars all along the penetrators flight path that would be necessary to classify and track it. On the front lines, all it has is itself and datalink with other tanks along side it which won't help at all to track KE penetrators.
Iskander will still deny that he is wrong.
Iskander can be told a FACT and he will deny it and bring up some useless infomation that was published back in 2000 or even before.
He with out a doubt has an inferiority complex with the west!!!
Have you even read the information published by KBM or looked at there website?
the israeli iron fist APS is being developed to intercept KE rods
i don`t actually care that you say about it - KBM , thats the company that make and sell it , quite clearly state it is not designed to have an effect whatsoever against APFSDS shells ; it is designed to intercept ATGM`s and grenades.
so continue to argue with blocks of pointless text , the company that make the system have contradicted you.
