L-4 "Grasshopper and the unusual story about it as the tank killer
L-4 Grasshopper was the light observing aircraft of the second world war, and one of the most unusual tank killers in history. That aircraft has been shown that also small aircraft must be taken seriously. And that model has been improved after the Second World War. For tank-killing duties this aircraft was equipped with "Bazookas", and it was used against German tanks during the Second World War.
The reason for that was that the German tanks were better than U.S tanks, and the army needed a fast-reacting antitank vehicle, which could attack against multiple targets in a large area. The idea was that the "Grasshoppers" would fly to the front, then attack against tanks and then get more ammunition. In modern models of this kind of aircraft the "bazooka"-rockets are inside the cassette, where they can use against the target as salvos. And the thing, why this kind of aircraft is still in use is that those systems are very low noise.
Small Cessnas and other things keep less noise than helicopters, even if there is some kind of noise suppression systems installed in the helicopters. The active systems would base the loudspeakers, what is creating a horizontal layer, what would not let the sound of the helicopter coming through that sound. And in passive systems, the key element is exhaust tubes, which turned upwards. That would focus the sound away from the observer, who is standing on the ground. And that thing is the key element of modern low-noise technology.
The lightweight aircraft, which is equipped with the hollow explosive rocket, which can effectively penetrate the armor had given route to the many other things, like antitank helicopters and other vehicles. In modern times the small Cessnas are sometimes equipped with antitank or antipersonnel weapons, and the thing, that makes the HEAT ammunition very useful is that weapon can fill with propane, what is tanked on the front of the explosive.
If the chamber of the HEAT ammunition would be filled by using hydrocarbon, that thing causes an extremely powerful explosion. In some cases, this kind of model has been transferred to the anti-guerrilla operations, where they have been used with FAE (Fuel Air Explosives). This kind of explosive is effective even in the small size, and that makes them very deadly tools in the cases when the targets were some kind of guerrillas.
