US plans new space sensors for missile defence against 'rogue states'

Trump likely to present Pentagon findings about changing threat as justification for his planned 'space force'

Donald Trump will unveil a plan on Thursday for a major expansion in US missile defence that will rely on a new generation of space-based sensors.

The administration's long-delayed missile defence review, which the president will present at the Pentagon, will call for the expansion of the US network of sensors and interceptors designed to identify and shoot down incoming projectiles from "rogue states" such as Iran and North Korea.
