GPS Spoofing Forces MSC Antonia Aground in Red Sea

January 23, 2026

INCIDENT

On 10 May 2025, Liberian‑flagged container ship MSC Antonia ran aground in the Red Sea. The ship was en route from Marsa Bashayer, Sudan, to Jeddah, Saudi Arabia. Multiple maritime intelligence analyses have determined that the grounding was caused by deliberate GPS/GNSS interference — including spoofed and jammed signals. The interference misled the vessel’s navigation and AIS positioning systems. The Antonia remains aground as of mid‑May 2025, with efforts underway to refloat the vessel. All crew members were reported safe, with no injuries from the accident.
