A pocket-sized spy drone disguised as a hummingbird has been unveiled by a major Pentagon contractor measuring just 16 centimetres and weighing less than an AA battery.
The mini spy plane can fly up to 11 miles an hour and took five years to develop at a cost of $4million.
Army chiefs hope to use the drone's tiny camera to spy on enemy positions in war zones without arousing detection and eventually deploy it into both rural and urban environments.
Experts hope the drone, which can fly just by flapping its wings, compared with current models which rely on propellers, will eventually be able to swoop through open windows and perch on power lines.
The demonstration by AeroVironment - one of the world's biggest drone suppliers - lasted eight minutes and saw the new creation fly through a door into a building and out again, and withstand winds of five miles per hour.

| Unsuspecting: The tiny hummingbird spy drone has a wingspan of just 16 centimetres and propels itself like a real bird - just by flapping its little wings |
Current drones, like the $30million Global Observer, pictured, are shaped like planes - but the new hummingbird creation is aimed at going unnoticed behind enemy lines |
Todd Hylton, Hummingbird programme manager for the Pentagon's research arm said it 'paves the way for a new generation of aircraft with the agility and appearance of small birds.'
Matt Keennon, AeroVironment's manager on the project, said the milestone of building a machine inspired by nature pushes the limits of aerodynamics.
He added: 'This is a new form of man-made flight'.
AeroVironment already produces a number of different drones for the US Army.
Last year it had 2,182 orders from the army for its Raven drone, which weighs four pounds with a wingspan of four-and-a-half feet.
Around 86 per cent of its orders come from the Government, meaning last year it was paid a whopping $215million from the Department of Defence.
The company, based in California with 732 full-time employees, expects to sell even more drones to the Government once rules are relaxed to allow spying within America.
The unveiling of the Hummingbird comes just weeks after the same company launched its $30million Global Observer with a wingspan similar to a Boeing 747 which can survey an area as large as Afghanistan.
Chris Fisher, project manager at AeroVironment explained: 'It gives the guy on the ground the opportunity to see what's on the other side of the hill. There's only so much you can see with binoculars. A small [drone] can get up and go over the hill. That gives the ground soldier a capability that is huge.
He added: 'One of the things we benefit from is the average young person in the military has hours and hours of video games experience. They are attuned to holding these things in their hands; moving the joysticks around with their thumbs and that's how our planes are flown. To an 18-year-old it's extremely simple.'
