I must admit that for all of my attempts to really enjoy well made, clever, artsy films, deep down I love a good action film. There’s something about sitting down for a couple of hours and watching something very reassuringly formulaic unfold before your eyes. We all know that things will explode, the bad guy will get away a few time and eventually the hero will capture/kill the bad guy and rescue/sleep with the girl. But there’s something encouraging and uplifting about seeing this script unfold in front of a backdrop of explosions.
So it was that my Sunday evening happened to be spent watching an action film in bed (X-Men 2 since you asked). During one of the plane chases I found myself asking, sure homing missiles are great, but how on earth do they work. Which was fortunate as to that point I was worried that I may not have learnt anything on a particularly mindless Sunday.
As you may well expect, missile systems are a relatively complex thing. First the system provides the launcher with short and long range navigation. The system the identifies whether the target is a friend or a foe by picking up their transponder code which is assigned to all military airplanes and personnel. Then the pilot picks missile type and the system checks numerous functions to ensure that they are in full working order.
When the missile launches it enables it’s on board battery to power it’s electric systems. The launcher’s tracking radar monitors the missile’s progress and computers continually judge them targets locations, course, speed etc. This information is used to continually adjust the missiles flight to ensure that it can intercept its target. When the missile reaches a certain proximity, it initiates it’s own radar to search for the target. The missile has a component to allow it to judge when it is the perfect distance away to cause maximum damage and then, finally, it explodes.
Turns out a lot goes in to making one missile find its destination. It makes you realise that military technology has come a long way since World War 2 and it’s a wonder that more aren’t killed in the line of duty.
