Iridium's $5B satellite phone network went bankrupt nine months after launch

Motorola conceived Iridium in the 1980s as a satellite telephone network that would cover the entire planet, including the poles, oceans, and every patch of land that cellular towers did not reach. The system required 77 low-Earth orbit satellites — the element iridium has 77 electrons — and cost approximately $5 billion to build, making it one of the most ambitious private space projects of the 20th century.

Iridium launched commercial service on November 1, 1998. The handsets cost $3,000 each and weighed 454 grams — about the size of a brick. Calls cost $3 to $7 per minute. The service required a line-of-sight connection to the sky, making it unusable indoors or in cars. By the time the network was operational, cellular coverage had expanded far beyond what Iridium's original business plan had assumed, and the target market of business travelers simply did not see the value.

On August 13, 1999 — just nine months after launch — Iridium filed for Chapter 11 bankruptcy. The company had approximately 20,000 subscribers, far below the 500,000+ needed to service its $4 billion in debt. Motorola wrote off its investment. In March 2001, the Iridium system was sold out of bankruptcy for $25 million to a private investor group. The sale was a fraction of the $5 billion construction cost and one of the most dramatic wealth destructions in telecom history.

The new owners restarted service in 2001 with a lower cost base, targeting niche markets — maritime, aviation, military, and oil and gas. The company eventually became profitable, listed on NASDAQ in 2009, replaced its constellation with the $2.9 billion Iridium NEXT system, and reported $830.7 million in revenue in 2024. In June 2026, Iridium agreed to be acquired by Rocket Lab. The story is one of the great comebacks in business history, but it does not erase the original failure.
