Rockwell International announced that GSFC had awarded it a $6.5 million contract to produce seven more RS-27 engine systems for NASA's Delta launch vehicle, to be delivered beginning in October. Each of the liquid fuel systems consisted of a main engine and two vernier engines combining to produce about 207,000 pounds of thrust; Rocketdyne-built hardware left over from the Saturn program would be used in the new system, reducing costs to the taxpayer. Rockwell would static-test the systems at its Santa Susana laboratory in California before delivering them to NASA; it had delivered 60 RS-27 systems since production began in 1973. In the 150-launch history of Delta, 101 launches had used the older Rocketdyne Thor MB-3 engines; the other 49 used the newer, more powerful RS-27s. (Rockwell Release RD-1)
