What happened

Israel and Iran fought a twelve-day war from 13 June 2025 to 24 June 2025.[6]

On 17 June 2025 the tanker Front Eagle collided with the tanker Adalynn about 25 nautical miles north-east of Khor Fakkan, UAE; Adalynn's 24 crew were evacuated.[1]

Windward said Front Eagle had experienced sustained GPS and AIS interference beforehand, and that about 1,000 vessels were affected by interference in the region between 12 June and 15 June.[1]

Front Eagle's operator, Frontline, called the collision a navigational incident unrelated to the conflict, and no source has shown that interference caused it.[1][5]

What our map showed

Our map shows aircraft reporting low GPS position accuracy. It does not show who or what caused it. A day is a full UTC day, so short events can be diluted.

Ships use AIS, not ADS-B, so our map shows aircraft over the same waters, not the ships themselves.
