Attack Helicopters combat survivability

Can you enlighten me what is with Longbow Radar in helos ? Is it some sort of silver spoon to avoid Helos from threats ?

There was some discussion not too far back, I think it's in the last few pages of the Ka-52 thread.

Anyways, longbow is the mast mounted radar on the Ah-64. In theory, it allows it the hide behind a treeline and look over top for tanks and whatnot, without exposing the gunship itself. The Soviets had really good SHORAD; shilka, Tunguska, etc. Conventional strafing or circling like you see in Iraq and Syria, would have be suicide on the battlefield the Ah-64 was designed to fight on.

No. It allows the helicopters to spot the enemy from a ways away and allows the helicopter to track a target and use the Hellfire AGM-114L to a designated target. Problem is, it has 8km range and a shorad such as pantsir or latest variants of Strela-10 would be able to also detect it within range. Pantsir and Tunguska would see it even farther away and be able to take the helicopter down from that far. While it is a good system, it doesn't actually protect the helicopter from the enemy at such distances if the enemy has a half decent shorad. While Vikhr can operate at same range as hellfire or even greater (10km), it still falls within same ranges of the shorads. Now the issue is that the person thinks that the helicopter can fire and just flee. But I don't believe that is entirely true as it may need to still gain the info from the longbow radar (someone please correct me). And against the targets in question, both Ataka, AGM-114 and Vikhr works perfect, with the Vikhr and Ataka costing not nearly as much as the expensive AGM-114. But they require the helicopter to be tracking the targets with its laser system. Mind you, the helicopters such as Mi-28nm and Ka-52 carry radar so theoretically I imagine they could use 9M123 and operate similar. I am also not sure of this though.

The whole discussion was really sad. This Scar guy was getting extremely defensive and didn't provide any actual information to back up his claims but was quick to call others people claims drivel but not actually properly argue it or explain in detail.

Hermes is supposed to be related to the Pantsir-S missile and will be ground, air, and sea based with a precision delivered payload of about 30kgs... it should be rather potent.

It would be interesting in the sense that the Pantsir-S is inertially guided and then command guided for the terminal phase but these missiles are inertially guided and then terminally guided.

One would suspect they could still be used against an aircraft, so that means any nearby Hermes artillery batteries could be used to support a Pantsir-S battery against a heavy air attack... perhaps with laser homing or MMW radar or IIR seekers in a fire and forget mode.

The point is that no one there is entirely correct. At some points they are correct but the deeper the discussion goes the more they show halftruths, lot of myths and missconceptions aswell not a single person there even understands or appears to have not read any manuals of any army how they are operating and the factual reality of engagement procedures and ranges. Maximum weapons range is all fine and dendy, but Apaches could not even come above 5km maximum Hellfire range in a plain, desert with almost no cover for iraqi tanks and they still had an average engagement range of 3.2km. Now imagine the very same scenario in a urban/rural battlefield in europe. Helicopters would enter effective and lethal zones of even the weakest 14.5mm KPVT machineguns and militaries tend to have something bigger for everything that flies where it shouldn't.

Especially important point, considering that the Apache's cockpit glass isn't even rated to defeat 7.62x39mm/AKM fire let alone 14.5x114mm, 23x115mm or even 30x165mm caliber rounds fired from a Tunguska/Panstir.

Also I don't know why people keep talking about the ability for helicopters to hide behind tree-lines as being touted as some kind of major advantage, when SHORAD can hide behind tree-lines even easier than helicopter could, and with the additional advantage of electro-magnetic spectrum camouflage. What's also interesting is that Russia has developed and putting in to service ground surveillance radars capable of differentiation of objects needing only 5 cm of separation, which are also capable of differentiation between blades of grass and vegetation, trees, animals, human figures....so recognizing an helicopters blades would be child's play for those radars.

I remember chatting to a guy in the 1990s who was a tank commander and he said the thermal imagers they had then and the fire control systems meant that during exercise he could easily see helicopters hovering behind trees just by the heat signature and exposed rotor blades. He said the army he was in didn't have dedicated anti helo rounds but an APFSDS round would completely penetrate any tree or group of trees like a white hot knife through butter and smash a helo out of the sky behind.

A Russian tank commander in a T-90M could of course lase the tree and then add 10 metres and fire above the tree with a standard HE FRAG round fitted with an ANIET fuse and set the round to explode directly above the helicopter... with devastating results...

The problem with this tactic of scanning for targets while hovering behind trees is two fold.

Not only can any modern PESA ground based SAM radar track such targets, since to hover in 10-30m altitude means that you are not further than 4km away from the SAM/SHORAD, which means you are as clear as a dying star at a night sky, despite trees being some source of clutter reflection, but the background is still the Sky a very poor environment of clutter and reflections of radar waves, aswell rotor blades have a very high amount of radar wave reflection aswell they are easily distinguishable from most sources, since they turn and have constantly a changing angle and surface they reflect the radars back, which every SAM radar can track and recognize as a source of artificial object and not a clutter.

That was the first problem, very short range, highl RCS since radar and rotor blades are still lifted above trees/obstacles.

The second problem is that was found with Longbow radar based on the MMW which has a high resolution but from a very flat illuminating angle like in the case of hovering behind obstacles, the system has very hard problems distinguishing a source and where exactly it is. The radar waves come flat in and come flat back and the radar can not distinguish accuratley how long the tank is or might even be filtered out like the tests have shown problems with the high amount of stationary targets being seen as clutter and filtered out. While the helicopter tries to scan for the target tank a close by Shorad will immidiatley notice the radar scanning and will not have huge problems to find its prey and work against it.

Those problems are years old and have been only addressed since the Block 3 came out and to what level they have been solved is a different question, but such problems are normal to such radars especially for their purpose. The amount of clutter a sky gives is almost non existent compared what all the sources for clutter on the ground can produce and those were the results from Iraqi flat desert with low amount of objects. Europe would be a nightmare for using Radars with lot of success in this kind of setting or purpose.

Radars should always be seen as sumpliment for awarness never as a garantee or a major technology that should have highest priority for pilots and what sources of information they should trust. Military intelligence of observers and UAV's are much more useful for that role than radars, but they are just as subject to camoflauge tactics of military to hide entire weapon plattforms.
