Stratolaunch has revamped its website with some new photos of its gigantic carrier aircraft under construction at the Mojave Air and Space Port.
The twin fuselage airplane will be the largest aircraft in the world, with a 385-foot wing span. Powered by six Boeing 747 engines, the aircraft will have a payload of more than 500,000 lbs. (226,796 kg) and an operational range of approximately 2,000 nautical miles (3,715 km).
The Stratolaunch aircraft is designed to air launch launch vehicles. The company has an agreement with Orbital ATK to use its Pegasus small-satellite booster.
In March, billionaire backer Paul Allen has said he hopes the carrier aircraft will make its first flight test by the end of the year.
