According to local media reports, the appearance of the ship forced a postponement of tests at a U.S. missile range.
The U.S. Pacific Fleet was keeping a close eye on a Russian reconnaissance ship that was off the coast of Hawaii near an important U.S. missile range.
The U.S. Naval Institute reported that the Russian Navy’s general reconnaissance ship Karelia was spotted last week off the coast of Kauai.
The ship was operating just off the U.S. territorial waters, about 24 kilometers west of the island.
International waters begin 22 kilometers from the sovereign shoreline.
On the island of Kauai is the Barkin Sands Pacific Missile Range, which is used by the Navy and the Missile Defense Agency for missile testing.
It is a range where submarines, surface ships, aircraft and spacecraft can operate and track simultaneously.
The Honolulu Star-Advertiser newspaper reported that a missile test of the Missile Defense Agency was postponed because of the appearance of a Russian ship.
U.S. Pacific Fleet spokesman Captain John Gay said in a statement to the USNI news portal that the U.S. Navy was “aware of a Russian ship in international waters around Hawaii,” noting that they would “keep an eye on it.”
