In response to industry requirements Boeing has developed the capability to enclose payloads in the fairing prior to transport to the launch pad for launch vehicle integration. Both Delta 2 and Delta 3 use the same Boeing-built booster engine, as well as similar avionics systems, launch operations infrastructure and liquid oxygen tanks to minimize cost and maximize flexibility. The diameter of the booster fuel tank was increased from the Delta IIs to reduce length and improve control margins. Fla. handles launch coordination and operations. Calif. The first Boeing Delta 3 sits atop pad 17B at Cape Canaveral.
Cryogenic fuels produce more energy, allowing lift of heavier payloads.
The RLB10-2 also incorporates a larger exit cone for increased specific impulse and payload capability. It provides contamination control and protects the satellite from aerodynamic, acoustic and thermal environments through launch and ascent phases of flight. Flight software includes the standard flight program and a mission constants database specifically designed to meet the customer's requirements. The solid rocket motor storage area, Delta checkout facility and high pressure test facility at Cape Canaveral also were modified to assemble and check out the Delta 3. The site is capable of processing and launching both Delta 2 or Delta 3 vehicles.
