Lockheed Martin and D-Wave will collaborate to realize the benefits of a computing platform based upon a quantum annealing processor, as applied to some of Lockheed Martin's most challenging computation problems. Lockheed Martin established a multi-year contract that includes one system, maintenance, and services. [43]
The new craft was designed and built by prime contractor Lockheed Martin Skunk Works in Palmdale, California, under a $247.5 million NASA contract. With factory rollout now complete, the X-59 will ...
This is a list of aircraft produced or proposed by the Lockheed Aircraft Corporation from its founding as the Lockheed Aircraft Company in 1926 to its merging with Martin Marietta to form the Lockheed Martin Corporation in 1995. Ordered by model number, Lockheed gave most of its aircraft astronomical names, from the first Vega to the C-5 Galaxy.
The Lockheed Martin Skunk Works began developing the QSST in May 2001 under a $25-million contract from SAI. Designed to cruise at an altitude of 60,000 feet (18,288 meters) at speeds of Mach 1.6 to 1.8 (approximately 1,218 to 1,370 statute miles per hour, or 1,920 to 2,204 kilometers per hour) with a range of 4,600 statute miles (approx. 7,402 km), the two-engine gull-wing aircraft was ...
