The X-33 space plane will miss its first autonomous test flight scheduled for July because its graphite-epoxy composite fuel tanks have defects, and have failed tests.

The X-33 is a pilotless prototype for VentureStar spacecraft similar in all respects except scale, and is intended to reduce risk in the development of the full size spacecraft.

The first test flight from Edwards Air Force Base in California State to Utah State's Dugway Proving Ground is " definitely going to be delayed," said Rising, adding, "If we have to build aluminum tanks for the X-33, that will take about 18 months,"

Utah's Alliant Techsystems was paid more than $60 million by Lockheed Martin and NASA for to make the graphite-epoxy composite tanks,
