Delta III was an expendable launch vehicle made by Boeing. The first Delta III launch was on August 26, 1998.[4] Of its three flights, the first two were failures, and the third, though declared successful, reached the low end of its targeted orbit range and carried only a dummy (inert) payload. The Delta III could deliver up to 8,400 pounds (3,800 kilograms) to geostationary transfer orbit, twice the payload of its predecessor, the Delta II.[1] Under the four-digit designation system from earlier Delta rockets, the Delta III is classified as the Delta 8930.
