The Airlander 10 is a hybrid airship designed by UK-based firm, Hybrid Air Vehicles.

The lightweight airship, seen here in a concept illustration, can carry up to 10 tons and stay in the air for five days continuously.

It was originally designed for the U.S. military to use for surveillance of troops and conflict zones overseas. But a lack of funding grounded the project.

HAV bought the technology back and is underway with plans to lift off again thanks to a £3.4 million ($5.1 million) grant from the UK government, aimed at helping emerging technologies and job creation.

The helium-filled Airlander is pictured in a giant shed in Cardington, England, in February 2014.

The craft's cockpit has space for one pilot and an observer. Here, Bruce Dickinson, singer with rock band Iron Maiden, sits in the driving seat. He is one of the company's private investors.

At just over 300-feet long, the Airlander is the world's largest aircraft -- longer than the largest commercial passenger airliner, Airbus 380, pictured (239 ft) and the Antonov An-225 (275 ft).
