The Sidewinder has a highly explosive warhead and an infrared sensor for target detection. The Sidewinder’s guidance system was designed to lock on to the hot exhaust of aircraft engines or anything else that shows similarities with an engine. With a price of 85,000 US-Dollars, the Sidewinder is relatively cheap and it has limited all-weather capabilities. The Sidewinder is a Fire-and-Forget missile, meaning that it is able to destroy a target on its own after lock-on.
