An insect-sized spy drone with four flapping wings and four legs is set to become Britain's latest weapon in the war on terror.

The Dragonfly drone fits in the palm of a hand and has four flapping wings and four legs.

It can fly through the air with great agility, allowing it to penetrate buildings through open windows, and perch on surfaces to eavesdrop.

It can detect incoming objects and buildings, meaning it can avoid obstacles at high speeds.

It is one of a number of pieces of kit being developed by the Ministry of Defence as part of an innovation drive.


An anti-drone device that uses lasers to burn holes in enemy drones will also be added to the Army's kit.

It works in two ways - burning a hole in a drone to damage its electronics, and overloading light sensors on the aircraft causing it to malfunction.

The MoD's innovation fund is overseen by a Dragon's Den-style panel, which companies and individuals can pitch to.

There is £800m up for grabs over a 10-year period, to support research and development for new weapons.

A mobile robot that can detect chemical weapons is also being developed, as well as virtual reality helmets to let pilots train on the ground.

Defence Secretary Michael Fallon said: "This new approach will help to keep Britain safe while supporting our economy with our brightest brains keeping us ahead of our adversaries.

"Backed by a defence budget that will rise every year until the end of the decade, it will ensure that the UK maintains its military advantage in an increasingly dangerous world."
