Iridium Communications Inc.

Iridium Communications Inc. stands out with a constellation of 66 low-Earth-orbit satellites delivering true global coverage[1][2]. This unique architecture – where each satellite links to its neighbors – ensures resilient worldwide connectivity even in the most remote or contested environments[2]. Iridium’s network has become mission-critical for sectors needing beyond-line-of-sight communication, from military push-to-talk systems to maritime safety services. As Europe pursues its own secure satellite connectivity (e.g. the IRIS² program), Iridium represents both a model and a strategic partner to watch: its L-band network can provide an alternative to non-European providers, yet its U.S. ownership also highlights the very dependency challenges that EU strategic autonomy seeks to overcome[3][4]. The reader will find below a deep dive into Iridium’s corporate structure, technology offerings, and role in the European defense-technology landscape – assessing how this U.S. satellite operator aligns with Europe’s goals for interoperability, deterrence, and supply-chain resilience.
