A US Navy ship operated in the Irish Exclusive Economic Zone (EEZ) for a period of four months.
Virginia Ann, a coastal supply vessel with a gross tonnage of 3,518 has capabilities for advanced subsurface activities.
During this time, the ship reportedly had its transmitter turned off, according to a report by the Irish Times.
The ship's actions raised concerns among Irish authorities regarding compliance with international maritime laws.
The ship's presence without an active transmitter hindered its visibility to other vessels in the area.
The Irish government lodged a formal complaint with the US government over the ship's activities.
The US Navy responded, stating that the ship was operating lawfully and was engaged in routine operations.
The issue highlighted the importance of transparency and communication between nations in maritime activities.
