On the turret there are 24 smaller vertical launcher tubes likely intended for that (aside of another 24 rotating smoke grenade launchers). What they atually launch is another question. The vertical launchers are for multi spectral smoke and soft countermeasures against top attack. Against Lahat, normal horizontally launched smoke grenades will do the job. Perhaps in the future one one of the two vertical smoke launchers could be replaced with other hard kill interceptors (just like the ones of the Arena-M, cassettes that launch vertically and rotate mid air so that the explosion and fragments go upwards). But i digress, people often forget that APS also comprises softkill measures. Beer 1 Quote Link to comment Share on other sites More sharing options...

That's possible basically only in deserts or if the enemy is completely stupid. Sorry for the double post. It´s not that hard. Lahat travels at 250-300 m/s. During that time, the shooter has to be static in position. That gives the T-14 up to 20 seconds to locate the shooter in a straight line. Depending on the range characteristics of the T-14 radar (of which we can only speculate) it may even track the Lahat since (or shortly after) the launch. However Afghanit not only detects ATGMs via radar, there are also visual detection devices, which could make locating the point of origin even easier (and this without accounting for the automatic target recognition capabilities claimed for the FCS). All this, while valid for ATGM, is also valid for any kind of ammunition shot at the tank. As an israeli tank commander said in an interview last year: an APS isn't really a defensive system.

Actually the scenario I was picturing was more the t-14 being lazed by a drone overhead or something, rather than the tank itself - although iirc the sights it uses are capable of laser designating. Also I was just spitballing what the guy might have meant. Its certainly possible he was just using the term missile to refer to the L55A1 apfsds round being developed to counter the newer soviet armour.

Lahat is still a very good option though and the only GLATM available in 120mm. While i doubt its effectiveness against T-14 i do see it´s usefulness against the much more numerous against T-72 and T-90 models Quote Link to comment Share on other sites More sharing options...
SH_MM Posted July 11, 2020 Report Share Posted July 11, 2020 12 hours ago, alanch90 said: Lahat may have a very good maximum range (8km) and top attack but its not fire and forget and the missile is fairly slow, meaning that the tank has to be exposed to enemy fire during a long time. If the gunner loses visual on the target, the missile is useless. The claimed range seems questionable. While IAI states this range on its website, it doesn't distinguish between air-launched and ground-launched ranges. Wikipedia took its infromation from an old Defense-Update.com article, which weren't the most reliable When Rheinmetall offered the integration of LAHAT into the Leopard 2 MBT, the maximum range was stated as about 6 kilometers. 11 hours ago, VPZ said: Lahat can be detected only when target is illuminated by laser (at the end of the flight). First of all, LAHAT can still be detected by all kinds of sensors - optical/IR/UV sensors, radars, etc. LAHAT needs the target to be illumanted in order to be a laser homing missile. Firing the missile, then hoping the tank remains in place/at a position that a last second laser illumination will allow it to hit the target is not a realistic scenario. 7 hours ago, alanch90 said: Lahat is still a very good option though and the only GLATM available in 120mm. John Cockerill and Luch of Ukraine also have developed the laser beam-riding Falarick ATGM in the calibers 90, 105 and 120 mm. The 120 mm Falarick has a range of 5,000 meters, but with just 630 mm penetration against steel armor protected by ERA, it has more of a multi-purpose warhead than an anti-tank one. There is also Luch's Konus ATGM for the T-72-120 and T-84-120 Yatagan, from which the Falarick was derived. It has a slightly more powerful warhead (minimum penetration of 700 mm steel after ERA), but that still falls short by quite a bit from being a threat to the T-14 Armata tank.

It's impossible because of topography. Even optical artillery observation systems placed on ground platforms are limited there to maximum 3 kilometers.

If fired on 3000 meters far target, the APFSDS will get there in around 2 seconds. LAHAT would need some 10-15 seconds. For all the time the target has to be illuminated and the missile flies slow and is relatively easy to detect and eliminate through both soft and hard kill measures - good luck with APFSDS. That has to be taken into account because here we speak about the future armament of the Challenger, i.e. for use against future threats (most likely more modern and more capable than those of today). Sure it's good against T-55 in the desert but in any case it seems to me like another example of preparing for a war of the past. Ground-launched ATGMs sure still play a role but nearly all their advantages can be exploited by an infantry team hidden somewhere on the hill with a long line of sight. The purpose of a tank is different. Quote Link to comment Share on other sites More sharing options...

To add to the point - modern ATGMs are getting longer anges and NLOS capabilities (Serbian ALAS, Isreali Spikes, French MMP, Chinese AFT-10 and so on) and a jeep or lightly armored AFV can fling much more powerfull and more effective ATGMs than a tank. GL-ATGMs can be somewhat usefull for a tank to fight against enemy infantry ATGMs teams using not a top of the line weapons, but it needs to be NLOS or at least F&F capable and have range of a Kornet; or in long range ambush situations, when first hit probabiliy against moving targets is very needed.

I don't think that NLOS is something for a tank. IMHO tank shall do tank things and not play also the supporting roles. But I do agree that if a missile is used in a future tank, it shall be F&F.

NLOS means that you can fire on an enemy which is out of your line of sight and that means you need some means and people to monitor beyond the line of sight which is not a work of the tank and its crew.

Not only that. If the missile is LOAL (lock on after launch) able (like Brimstone, Spike, etc.), then the operator can fire it in a general direction and either he himself looking through the missiles optics can lock on a target, or alternatively, the missile can lock itself on whatever seems like a target under the parameters chosen by the operator before firing. In a GLATGM this is very useful for example against enemy tanks that are shooting and going immediately hull down. So, if you know that "behind that hill over there" there's an enemy tank platoon in prepared firing positions, you just use these missiles and problem solved (unless there are APS involved). Supposedly these capabilities are built into the Sokol-V and that's why i see it as a very significant leap compared to previous soviet derived GLATGMs. Quote Link to comment Share on other sites More sharing options...

Beer Posted July 23, 2020 Report Share Posted July 23, 2020 The LEP has a completely new turret, right? Does it mean that the single piece ammo is all stored in the bustle and not just everywhere around the tank like with the standard Challenger 2?

Serge Posted July 23, 2020 Report Share Posted July 23, 2020 Yes. They are. A one piece ammo is so long, you can’t find tiny place to stow it. Not the least point : segregation of ammo from the crew is called to improve the whole tank survivability.

BaronTibere Posted July 23, 2020 Report Share Posted July 23, 2020 If you watch the video rheinmetall put out recently there is a glimpse of what looks like a leopard 2 sized bustle rack. So I don't think all the ammo will be in the bustle, especially given the location of the commander's sight. I expect the rest is in the hull somehow.

N-L-M Posted July 25, 2020 Report Share Posted July 25, 2020 In the Challenger 2, much like the Chieftain and Challenger 1, the ammo in the hull is stowed all over the place, but the 3 main bins of vertical propellant charges, if removed, provide adequate space for storing unitary ammo horizontally. Likewise, the frontal hull propellant racks, when removed, provide some more space there, though that likely requires rejiggering of the rest of the internal components there, as the unitary 120 is much longer. Perhaps that area wasn't touched, and the 15 are stowed horizontally where the 3 main bins were, nose to nose from 2 sides. Such an arrangement would also make them fairly accessible to the loader, somewhat making up for the low overall load.

FORMATOSE Posted July 25, 2020 Report Share Posted July 25, 2020 I guess they retained the stowage space on the right side of the driver, putting the 15 rounds on his left. Quote Link to comment Share on other sites More sharing options...
