NASA issued a Cooperative Agreement to Lockheed Martin worth about $1 billion over 42 months to build and fly the X-33.

NASA's industrial partners, in addition to Lockheed Martin, and its Skunk Works research, development, and testing facility in Palmdale, California, were Boeing Rocketdyne (engines), B.F. Goodrich Rohr (thermal protection systems), Sverdrup (ground support equipment). and AlliedSignal (electronics).

• Lockheed Martin

In addition to the Lockheed Martin homepage, the firm supplies news about the X-33.

For the latest news from Lockheed Martin on the X-33, check out their press releases.

Lockheed Martin planned to use the experience gained in designing, building, and flying the X-33 to build a commercial reusable launch vehicle to be called VentureStar.

• Lockheed Martin Skunk Works

The Skunk Works has been conducting secret developmental work since World War II.

The name "skunk works" comes from a comic strip called "Li'l Abner," and the strong odors that characterized the facility's early years when it was located in Burbank, California.

It was the locus of most X-33 activity, including most importantly construction of the vehicle.

Although the Skunk Works maintains a home page, the firm does not furnish a special X-33 page.

Skunk Works is now referred to as Lockheed Martin Aeronautics Company-Palmdale, CA.

• Rocketdyne

Now that Rocketdyne has been integrated into parent corporation Boeing, the firm no longer has a home page as such.

• Rohr

Rohr is now a division of The B.F. Goodrich Company. The Rohr home page is now up and running with a company overview, financial information, "Products and Programs," and a "News & Events" section.

• Sverdrup

Visitors to the Sverdrup home page no longer can find information about the company's participation in the X-33 project.

• AlliedSignal

Since the merger of AlliedSignal with Honeywell, the AlliedSignal home page no longer exists. Instead, it has been replaced by the Honeywell website.
