A Boeing Delta II rocket lifted off the pad here at 5:37 a.m. PST, successfully placing five Iridium satellites in a parking orbit before being deployed to their service orbit 85 minutes after launch.

Delta rockets now have deployed 55 satellites over eleven launches for

the Iridium system, a global wireless communication network combining

the worldwide reach of 66 low-Earth orbit satellites with land-based

wireless systems to enable subscribers to connect with hand-held

telephones and pagers virtually anywhere in the world. The Iridium

system is the largest commercial satellite constellation ever launched

by Boeing.

"We're proud to support this impressive undertaking that will

revolutionize communications as we know it," said Darryl Van Dorn,

Boeing director of NASA and commercial Delta programs.

Boeing builds the Delta II rocket in Huntington Beach, Calif., while

its Canoga Park, Calif., facility produces the Rocketdyne RS-27 first-

stage main engine. Final assembly takes place at the Boeing facility

in Pueblo, Colo. The Delta launch team at Vandenberg Air Force Base

handles launch coordination and operations for Iridium missions.

Alliant Techsystems, Magna, Utah, manufactures the graphite epoxy

motors for boost assist. Aerojet, Sacramento, Calif., builds the

second-stage engine, and AlliedSignal, Teterboro, N.J., produces

the guidance and flight control system.

The Iridium system is owned by Iridium LLC, an international consortium

of 17 investor organizations representing telecommunications and

industrial companies worldwide, with Motorola Satellite Communications

Group serving as the prime contractor.
