Bigger Delta II to Loft Sirtf
Los Angeles Boeing will build an uprated version of the Delta II for the Jet Propulsion Laboratory’s Space Infrared Telescope Facility (SIRTF) that carries about 10% more payload, or a total of 4,550 lb. to geosynchronous transfer orbit. The uprated launcher is called the Delta II Heavy Lift, and borrows the 46-in.-dia.
