J-CATCH (Joint Countering Attach Helicopter)

A dedicated Army aviation unit for counter air operations; is it necessary?

I've been searching the internet for info on attack helicopters and stumbled onto a 70's experiment called J-CATCH which has some very interesting results in helo's vs jets in combat. The second link actually provides kill to loss ratios from F-15's, F-4's and A-10's for the different types of weapons used. This is before the AMRAAM so if the test was done today, perhaps the outcome would be much different. Don't know. It's interesting to note that the helicopters were only armed with guns though.

Long time ago I read that a gunship helicopter, if armed with Sidewinder, would be quite formidable in the "dogfight" era of A2A combat, in large part because it could turn to point at the enemy quicker than most fighters could.

But as you say, modern BVR missiles could eliminate that threat entirely.

Some Cobra's had carried Sidewinders, though I don't think they often bothered to. This would have made a great anti-aircraft defense system for Army armored units, since many would often be escorted by gunships anyway. And we've seen Apache's with Stinger pods. But since there's been little threat so far to helicopters being threatened by enemy fighters, they aren't carried all that often.

And in fact the pics of Apache's you've seen with Stinger launchers must only be from when they have been in their test and evaluation phases or mocked-up, as even the latest Block Longbow's aren't even equipped to launch such weapons. Fitted, yes - but launched, no. And of note, the Comanche was going to be the first helicopter in the U.S. Army (or even the whole U.S. military) inventory that had a dedicated air-to-air capability. It was able to hold 12 x Stinger's internally or a whopping 28 x Stinger's in total with the stub wings fitted!

You are probably correct about the Longbow Apache. But I do seem to recall seeing a few pics or video of an older Apache actually firing a Stinger missile while in flight...probably from a static hover, onto some cheap target. I'm guessing it's more for a confirmation of launch safety for the helicopter than anything.

There was mention in the earlier tests I'd heard about, that it was more difficult to pick up IR signatures on helis at that time, because of the cooling effect of the rotors, and the distances for a jet using IR is typically further away. But that was the 1970's or so, and we all know that this would not be true of today's advanced IR seeker/trackers...the Russian Archer would likely not even need the heat from the engines at all to track a heli: the rotor tips might do the trick, and it's got a prox fuse like many today. Meaning, one heli down. Unless the heli gets a lucky shot in.

It's worth considering that the last time I checked the Pk of a Stinger, they listed it as about 25%. But that was in the late 1980's, and likely from a ground launch. I have no idea if that number has climbed, and if it would be higher from a helicopter launch.

Effective range is a real limiting factor (using IR short-range missiles from a near static launcher). Having even the occasional helo with a few manpads (or even an R-73!) does create a potentially pricklier environment for fast movers.

The few helicopter vs. helicopter kills happened in the Iran-Iraq war and involved ambushes using anti-tank missiles (often with SACLOS guidance)...

Concerning Apaches, for the Japanese AH-64D, or AH-64DJP as they refer to it, Stingers are actually standard issue mission equipment. (And besides that, they have a way cooler painting scheme, just not as cool as the Israeli ones! wink )

However, one major and possibly lethal drawback coming with helicopter A2A combat is the difference in average altitudes of helicopters and fixed wing aircraft. As FW AC mostly fly higher, a helo would have to point the nose up to focus/track/engage. I do know the AIM-92 has a larger sensor scan radius and the FCR can scan in a dome-shaped area but generally you would have to have a nose up orientation in a helo in a dogfight. And as you might already guess, nose up means slowing down which soon makes a helo a stationary sitting duck.

JayPee - Some good points you make!

In reply to an earlier comment regarding jet fighters having a so-called advantage with BVR missiles, bear in mind that these missiles work best with enemy aircraft at similar high altitudes with no obstacles. Helicopters would be almost on the ground in comparison, with 'clutter' and physical obstacles being in the helicopter's favor - meaning possibly no target acquisition to start with and a missile barrier, respectively.

Also, jets can out-fly and out-manouvre an incoming missile, especially lighter/cheaper ones like Stingers and Starstreaks. A helo can only hope to dodge high speed highly agile A2A missiles.

My mom always told me, never start what you can't finish. So I think it's safe to conclude that potential A2A missiles mounted on helos are solely for use against other smaller helos. Which brings us to the next topic, current pacts and alliances hardly allow hardware versus hardware wars. It's basically hardware versus insurgents living in tents shooting their AKs at a hull which can withstand direct incoming 23mm. The only relative challenge the US has faced was Iraqi hardware back in '91. And even they got rolled pretty badly overnight.

It's funny actually, every documentary or digital brochure you find about Apaches and similar helos brag about how these machines can take out massive amounts of armored vehicles in seconds. However, what is required nowadays are anti-personnel tactics and machinery. Lots of modern hardware is used for different purposes than what it was initially designed for. Simply because it was designed to fight a war which never happened.

Modern AAMs work just fine against helis. An F-15C is easily capable of picking up and classifying a helicopter that's landed, as long as the rotors are moving - from 40-50nm. Neither AMRAAM nor sidewinder had any trouble dealing with low flying helis (there's a famous blue on blue there as proof). Stingers aren't doing bad either. There's a reason why helis are mounting all manners of countermeasures, DIRCM, MAWS, and ECM suites these days ... the reason is that without their help, the modern fighter with modern AAMs will make short work of your eggbeater ... even if it's sitting on the ground.

GrayGhost - Thanks for the info, but I never specified 'modern' AAMs, just so you know that I wasn't even pretending to cover the whole spectrum with my perhaps seemingly complete answer.

So as long as the rotors of a helicopter are spinning, it is possible for an AAM to lock on and act as an ASM? Cool, so that little 'quirk' in Longbow 2 where I was locking onto landed Hinds, Hips and Havocs with Stingers wasn't a game bug then!?

Also if LB2 is anything to go by, no amount of fancy DIRCM, MAWS or ECM suites will do a sh*t the good, as it's the one who first gets a missile 'off the rail' that has the complete advantage. And as a Stinger only has a range of around 5 or 6 Km, we all know how that ends up...

In any case, I'd hope that Western missiles/acquisition suites are the most advanced and that any potential Eastern enemy would be using less advanced or older generation missiles/acquisition suites that are less effective at picking out helicopters from ground clutter, etc. As long as an F-15C has an advantage, that's all that matters!
