Summary
Iridium 83 to 87 launched on an United States Air Force Delta II 7920-10C from Space Launch Complex 2W, Vandenberg SFB, CA, USA on November 6, 1998. It was United States Air Force's 1,001st launch, 14th this year and humanity's 4,278th orbital launch attempt. It was the 11th Delta II 7920-10C flight and the 5th this year. The payload was bound for low Earth orbit (LEO). Iridium 2, one of 6 catalogued objects, reached a 530 × 541 km orbit inclined 86.0°. 6 objects from this launch are catalogued, 5 of them payloads.

About this launch
Iridium provides global mobile telecommunications services using a constellation of 66 low earth orbit satellites in a 86.4° inclined orbit. Although 77 satellites were originally envisioned for the system and spawned the name based on the 77th element in the periodic table, the system has been scaled back. Motorola's Satellite Communications Group designed and manufactured the Iridium satellites with Lockheed Martin providing the LM-700A spacecraft buses.
