The Stratolaunch is huge, but it’s not the strangest aircraft ever built in Southern California

Southern California has long been the breeding ground for new and unconventional aircraft.

It was the birthplace of such fanciful dreams as the Spruce Goose seaplane, which only had one flight. The region served as home base for a number of secretive military projects, such as the U-2 spy plane, the SR-71 Blackbird spy plane and the B-2 stealth bomber.

Now, another unusual aircraft is taking shape in Southern California — the Stratolaunch Systems giant rocket-carrying aircraft.

First announced in 2011, the giant plane is designed to air-launch satellites into orbit. It is expected to have a wingspan of 385 feet — longer than any plane every built — and is being constructed in Mojave, Calif., by Vulcan Aerospace, a Seattle company backed by Microsoft cofounder Paul Allen.

Take a look at some of the other unconventional aircraft and spacecraft that have roots in Southern California.

DC-3 airliner

The DC-3 airliner was built in Santa Monica by the Douglas Aircraft Co. in the 1930s and 1940s. The aircraft was the country’s first reliable passenger plane and revolutionized commercial air travel.

U-2 spy plane

The U-2 spy plane was built in Burbank at Lockheed Corp.’s secretive Skunk Works facility.  The plane has played a key role in U.S. intelligence gathering since its first flight in 1955.

X-15 rocket plane

The X-15 rocket plane was built in Downey by North American. The plane, which set altitude and speed records in the 1960s, demonstrated that a winged aircraft could fly to and from space.

SR-71 Blackbird spy plane

The SR-71 Blackbird spy plane was built in Burbank at Lockheed Corp.’s Skunk Works starting in the 1960s. The high-altitude jet set a record in 1990 for its cross-country flight from Los Angeles to Dulles International Airport, near Washington, in 68 minutes and 17 seconds.

Night Hawk

The F-117 stealth fighter/bomber, also known as the Night Hawk, was built in the 1980s in Burbank by Lockheed Corp.’s Skunk Works. After the introduction of the stealthier F-22 in 2006, the Pentagon retired its fleet of F-117s.

Voyager

The Voyager was built in Mojave by Dick Rutan, Jeana Yeager and others. The plane was constructed of hardened paper and graphite fiber and weighed only 939 pounds. In 1986, it completed the first nonstop, unrefueled flight around the world.

SpaceShipTwo

The SpaceShipTwo civilian spacecraft was built in Mojave by aerospace pioneer Burt Rutan’s Scaled Composites LLC for Virgin Galactic. SpaceShipTwo was intended to take paying customers into space, but an early version broke apart during a test flight in 2014.
