At just 2.4 kg (5.3 lb), the US Navy’s new Spike missile is significantly smaller than any other missile of its kind. It was originally intended to be used with a lightweight hand-held launcher, but its size meant it was perfectly suited to unmanned aerial vehicles (UAVs).

Spike’s highly precise targeting system combines an imaging electro-optical sensor with laser guidance and is capable of locking on to a target as small as a motorcycle.
