A Telemetry Probe is a device used by the UNSC. Its function is to attach to the hull of a spacecraft and track its movements through slipspace, reporting its findings back to the UNSC.

Operational HistoryEdit

In 2537, a prowler, the UNSC Razor's Edge, managed to attach one to a Covenant ship at the Battle of New Harmony. The warship was tracked to K7-49, a Covenant shipyard facility seventeen light years from the furthest reaches of human space.[1]

This sparked Operation: PROMETHEUS, in which the all 300 of the SPARTAN-IIIs in Alpha Company were deployed to destroy the shipyard. Although the mission was a strategic victory, with the Covenant abandoning what was left of the facility, Alpha Company was wiped out in its entirety.[2]
