Drones of Death - Q and A


In Afghanistan and Pakistan, more and more missions are being carried out by unmanned aircraft, also known as drones.
The drones, controlled 6,000 miles away in the Nevada desert, can carry up to 14 missiles.The United States has the Reaper drone, the Chinese have the Invisible Sword. Robotics expert professor Noel Sharkey, from Sheffield university, explains where drones came from, and what they can do:

How long have these drones been around?
Unmanned drones have actually been used for about 30 years. They were first used for surveillance.

When did drones start to be used in attacks?
The first test of an armed drone was in 2001 by the CIA. They put hellfire missiles on what is known as a predator drone, which was previously used for spying. These are the missiles they still use today.

When was the armed drone first used on a 'real' target?
The first deployment was in the Yemen in 2002, again by the CIA. They used it to blow up a sports utility vehicle in the middle of the desert. They claimed it killed an al-Qaida member, and five of his associates.

How many armed drones are there?
There are about 200 of the armed Predator drones now; while it also has a bigger brother now called the Reaper – which can carry 14 missiles, there are about 30 of those now too.

Who 'flies' them?
At the moment the drones in places like Iraq and Afghanistan are controlled from Creech air force base in the Nevada desert. In the US you can just take a course to learn how to control these aircraft, while at the moment the British stipulate that you must have been a combat pilot to control them.

How are they controlled?
It's a bit like a console games controller. These people are sat in front of a big screen. It is actually called a "man in the loop" system. It does an awful lot of things automatically. It has high resolution cameras and sensors – it sees things on the ground. It does have heat sensors to work out whether people are in a building or not.

Who makes the decision to fire the missiles, the drone or the human?
The pilot does, although on a lot of instances they won't have that much time – the drone will identify a target and ask them whether to shoot: yes or no? A lot of the time the pilot is vetoing targets rather than finding them.

How long can the drones stay in the air for?
The predator can stay up for about 26 hours, whereas some of the unarmed drones can stay in the air for up to 72 hours.

Are other countries developing these armed drones?
Yes, at the moment there are 43 countries developing these programmes. Russia alone has 18 programmes, while the Chinese have a drone known as the Invisible Sword.

Why have they proved so popular with military forces?
Firstly you don’t have to worry about your pilot getting fatigued or shot down. If they want to go to the toilet during a shift they can and someone else can take over. After work than can go home and have a meal with the wife and kids. There's also the cost: a drone can cost $40m, whereas a fighter plane can cost $350m.
