Lockheed Martin High Altitude Airship
Lockheed Martin is a respected name in the field of Aeronautics, electronics, information and space systems. The company has recently made yet another breakthrough airship and has named it HALE-D. The word HALE-D is an acronym and stands for high altitude long endurance demonstrator. The blimp is actually a big robot airship and is designed to operate at the altitude of 60,000 feet. The airship is powered by a series of photovoltaic cells.
The blimp works by floating up above the jet stream and then with the help of its motors it anchors itself at one place, offering a view of over 600 miles, and then helps in providing warnings about short and long range missiles, surveillance and target redemption, communications, environmental monitoring and everything else which a satellite is expected to do.
In other words, this airship, which is similar in functionality to satellites, is far faster, versatile, eco friendly and user friendly than the conventional satellites and above all it is far cheaper from its predecessors. Lockheed has recently finished work on the demonstrator and is awaiting concerned people’s responses.
