akd Posted February 5, 2015 Share Posted February 5, 2015 Are you sure about that? Well, that was the information released in conjunction with the mock-up of the system shown on a T-72B3 at RAE 2013. Regular arena is said to cover 20-40 degree vertical arch around the turret. From what I understand - Arena-E is fired at a straight vertical angle (i.e. 90 degrees) so in theory it should be able to engage anything flying above the turret...

Note the positioning and natural ballistic path of protective elements - what direction do you think they are designed to fly at by default? 0 Quote Link to comment Share on other sites More sharing options...
Sgt Joch Posted February 6, 2015 Share Posted February 6, 2015 turn the sound off... those victory shouts are annoying that is the best part, I love how he "chants" the missile onto the target. I may start using that in my PBEMs. 0 Quote Link to comment Share on other sites More sharing options...

Same or similar to old Arena. You may be confusing flight path of the munition with intercept envelope. The munition flies up and out, then fires a cone of shrapnel down at the incoming projectile, so a 45-60 deg. trajectory for the munition does not mean it can intercept projectiles approaching at that angle. 0 Quote Link to comment Share on other sites More sharing options...

Thank you for pointing out the obvious friend, of course the vertically launched explosive plates might very well change their tracjectory to intercept approaching missles from multiple angles, then again they may not and go straight for what is flying right above the turret. There are quite a few discussions of new Areana-E's capability to engage Javelins around the net; perhaps you might want to read up on a few before continuing this discussion? For the record, I am not 100% certain that it is effective anti-Javelin platform; but from the design standpoint - it is certainly much better suited for that role than the original Arena...

akd Posted February 6, 2015 Share Posted February 6, 2015 (edited) A new active protection system from Russia appeared today at RAE-2013, as part of the display of a series of upgrades offered to The T-72 main battle tanks. The new system, dubbed Arena-3 [Arena-E] covers 360 degrees in four quadrants with four modules, which seems to comprise two sensors two effectors. According to the manufacturer, two targets can be intercepted at each direction, at 0.3 second intervals. The system is effective at elevation of +20 degrees and -6 degrees. It is designed to intercept projectiles and missiles at a distance of 50 meters from the protected tank. The previous configuration included multiple effectors and a high profile radar that has not received well among tank crews. According to the tank manufacturer Uralvagonzavod, the system is effective at target velocity of 70-1000 meter/second (pertaining to RPGs, anti-tank missiles and HEAT tank rounds). The upgraded T-72 with Arena-3 weighs 46.5 tons. http://defense-update.com/20130925_a-new-arena-aps-debut-at-rae-2013.html Old Arena was +15 degrees and 70-700 m/s.

Look, Arena, let alone Arena-E are still semi-experimental systems that have not been addopted for service in any country. They are works in progress and any technical details that we can find on them are dubious at best... my point though was that the setup of Arena-E allows for vertial take-off (and likely) interception of missles at top angles. We certainly don't know that for sure, but that seems to be where this design is headed... which is only logical afterall... 0 Quote Link to comment Share on other sites More sharing options...

Nerdwing Posted February 6, 2015 Share Posted February 6, 2015 Wasnt -E the export variant anyways? Why would the -E be superior to the normal variant? 0 Quote Link to comment Share on other sites More sharing options...
panzersaurkrautwerfer Posted February 6, 2015 Share Posted February 6, 2015 Dude. You're both diming him out for not being precise enough about a system that might or might not do anything at this point, while using the lack of concrete information to speculate on capabilities that might be beyond merely an upgraded Arena system. Either way imagine the sensor portion of intercepting a very steep angle missile might be the bigger trick 1 Quote Link to comment Share on other sites More sharing options...
John Kettler Posted February 6, 2015 Share Posted February 6, 2015 Arena, an outgrowth of the earlier Drozd system, was designed to primarily deal with inbound ATGMs. That it was able to smite RPG projectiles was a bonus. The major problem with Arena was that all the supporting gear towered over their turret roofs, spoiling tactical surprise. Arena-E was developed to drop the vertical profile, making the tankers happy, but it caused a 25% loss of vertical coverage to do so. Neither Arena nor Arena E was designed to handle top attack weapons using a vertical type dive. there are technical solutions vs high divers, but Arena-E, as presently designed and implemented, can't do the job at all. Given a few sharp engineers and a decent budget, I bet I could come up with something very quickly and largely OTS to greatly increase survival odds vs top attack a la Javelin, but it wouldn't be cheap, starting with a zenith coverage radar system or something else to do the job.
