Also you guys to realize that there is a fragmentation warhead that is used in javelins that is very similar to fragmentation methods used for killing aircraft. Though mostly this is used for killing anything that isn't armored while it would still technically work just as good killing most commonly engaged armor targets.

Javelins are not suited for jets due to the short range though and slow speeds but things like gunships and helicopters are more than plausible targets as long as it has a strong IF signal to which just about every helo in the world has. I mean this is no different than shooting a javelin at a tank on top of a hill.

and ultimately if you expect it to do something out in the field you just created a demand for another contract; Things can get developed if they persistently become an issue to soldiers.

Slight problems.

Javelins are pure IR.

How would a helo pilot know he was being locked onto and fired upon? Unless he saw the missile separation he wouldn't know to launch flares and if you're using a top down attack he's just as prone to must humans to not looking up. His war is beneath him usually. As proven through the entire cold war, lack of training and experience does not make a technologically superior position immune to technologically inferior methods in hands of highly experienced personnel. So the whole agility argument goes out the window soon as a chopper pilot is caught idling somewhere to probably gun down your friends across the street.

Also the IR signal from a helo is near the engine exhaust which on most helicopters is on the top or the tail rotor. The fragmentation warhead was specifically designed to frag against very soft targets not penetrate so even a near proximity causes it to go off for max effect.

Finally Structural Paneling made with Aircraft Aluminium Grade is strong enough from most directions of impact to set most detonators off.

There are exceptionally very few helicopters that can eat an anti tank munition anyways, the HInd being the only one off the top of my head due to the compartmentalized firewalls.

Also if you want to attack a chopper, you do it from the top is the best way to do it. total lack of armor and generally that is where the engines are located.
