Gunmakers of the world's most deadly firearm has unveiled its first ever spy-in-the-sky drone and is planning on rolling it out for public sale.

The Kalashnikov Group famous for the AK-47 will officially reveal what it is describing as a noiseless unmanned reconnaissance and surveillance aircraft at next month's MAKS international air show near Moscow.

It has a four hour flying time and can be launched by hand as Vladimir Putin's biggest weapons maker takes a step back from its AK-47 - a rifle that has killed more people than any other firearm on the planet.

Nikita Zakharov, deputy chief executive of ZALA AERO, part of the Kalashnikov empire, claimed: 'There are no rivals to the ZALA 421-16E2 either in Russia or in the world for their functionality, simplicity and reliability of operation.

'The unmanned aerial vehicle has a noiseless flight mode which is so important for defence and security agencies.

'The first drones have already been handed over to customers.'

The drone is expected to complete Russian government trials this year.

The AK-47 assault was invented by Mikhail Kalashnikov in the former Soviet Union in 1947.

More than 100 million Kalashnikov rifles have been sold worldwide, accounting for a fifth of the entire global stock of firearms.

A study by the World Bank revealed between 20,000 and 100,000 people are killed every year by handheld guns in conflicts around the world.

It is predicted most of these were attributable to the AK-47.

The simplicity of the gun means that child soldiers, like the one pictured centre with an AK-47, can use them as murder weapons

The study said: 'The AK-47 was initially designed for ease of operation and repair by glove-wearing Soviet soldiers in arctic conditions.

'Its breathtaking simplicity means that it can also be operated by child soldiers in the African desert.

'Kalashnikovs are a weapon of choice for armed forces and non-state actors alike.'

It has since been adopted as the weapon of choice by the world's barbaric terror groups including Islamic State, who used AK-47s to spray bullets into the crowd at the Bataclan in Paris in the November 2015 atrocities.

In the same year, Tunisian Seifeddine Rezgui waged a campaign of terror in the popular resort of Sousse as he fired Kalashnikovs killing 38 holiday makers.

Among other Kalshnikov lines are speedboats, clothes and missiles.
