The thin guidance wires proved to be a simple and reliable way to send signals to the missile. The range of the missile is classified, but it makes for a couple of exceptionally long wires. Optical Night Sight Used The optical sight for tracking an enemy tank consists of a simple periscope that has both a visible and infrared mode. The infrared view can spot the tank's heat signature at night. This adds to the capabilities of the TOW system.
Some helicopters have the sight mounted on their mast or the top of their rotor.
This way the helicopter can hide behind a hill, with only the sight visible. The missile can then be fired and steer over the hill to the target, while the helicopter is safe from enemy fire. The TOW missile is an unusual anti-tank system that effectively uses wires to guide the missile to its target. I will try to get back to you as soon as possible.
