Starlink internet, operated by Elon Musk's SpaceX, has become a critical tool for Ukraine's military, providing vital high-speed connectivity on the battlefield.

The satellite network, which relies on over 10,000 active satellites, offers internet access in remote areas and conflict zones, proving essential for Ukraine's defense against Russia's full-scale invasion launched in February 2022.

However, a recent unexpected restriction by Starlink limited drone speeds to 100mph (160km/h), causing disruptions to battlefield missions and Ukraine's ability to counter incoming Russian attacks. Connectivity was reportedly restored by the following evening.

This incident underscores the profound impact Starlink's services can have on the conflict, with experts warning that such disruptions could lead to increased casualties. Kurt Volker, former US ambassador to NATO, stated that cutting off this communication capability would be a "cynical and callous decision."

Starlink's ease of use, requiring only a terminal pointed at the sky and plugged in, makes it ideal for battlefield deployment. Ukrainian soldiers report that the service simplifies reconnaissance operations by allowing real-time streaming and translation.

While Starlink is available for civilian use, SpaceX also offers Starshield, a military-grade service with enhanced security features like encryption, built upon the Starlink network. The US government has authorized Ukraine's use of both Starlink and Starshield.

In February, Elon Musk reportedly cut off Moscow's access to the service, a move that provided Kyiv with a significant advantage in communication and drone operations over conventional, more easily jammed radio networks.

The reliance on Starlink highlights a new dimension of modern warfare, where robust and resilient internet connectivity is as crucial as traditional military hardware, raising questions about the vulnerability of such critical infrastructure in ongoing conflicts.
