UK Prime Minister David Cameron has announced plans to replace the Royal Air Force’s (RAF) existing fleet of ten Reaper aircraft with more than 20 of the latest generation of remotely piloted air system (RPAS).

The new systems, which will be called Protector, will feature the very latest technology.

UK Defence Secretary Michael Fallon said: "The duty of the UK Government is to keep our country safe and we must do more as the threats we face evolve.

"This investment package will enhance our ability to address these sophisticated dangers both at home and abroad, allowing us to intervene with speed and precision to protect the people of the UK and our international partners."

The new Protector aircraft is expected to enhance the RAF’s capability to identify, track, deter and ultimately counter potential threats in addition to strengthening the country’s global intelligence surveillance and reconnaissance capability.

"This investment package will enhance our ability to address these sophisticated dangers both at home and abroad, allowing us to intervene with speed and precision to protect the people of the UK and our international partners."

Meanwhile, the new developments will also see enhancement of UK Special Forces’ equipment.

The force will receive new specialist weapons and clothing to make sure that the force benefits from latest technologies to make clear advantage over enemies.

The latest development is part of the 2015 Strategic Defence and Security Review (SDSR).

The UK Government earlier decided to spend 2% of national income in defence sector in order to meet the Nato investment pledge.
