The huge submarine spotted off the coast of Co. Donegal today may have been carrying nuclear warheads - but probably wasn't. Such a vessel is equipped to carry nuclear warheads, but it's thought this particular submarine wasn't doing so. "If they were packing nuclear warheads they would be deep in UK waters," the naval source said. All reported sightings of submarines are notified to Irish authorities but since this vessel was well outside the 12-mile range, it means it was outside Irish territorial waters. This submarine is operating on the surface outside Irish Territorial Waters and is in line with UN Convention on the Law of the Sea (UNCLOS) rules for transit through International Waters.
