Lawrence Brennan, a former US Navy captain and an expert on maritime law, said the Invincible is a scientific-research vessel and was unlikely armed except for “small arms for self defense.”

The US Navy officially lists the Invincible as a “missile range instrumentation ship” that monitors missile launches and collects data, so it was likely in the region because of Iran’s repeated ballistic-missile launches.

The Invincible carries out a mission similar to that of the Russian spy ship that sat outside a US submarine base in Connecticut.

CNN reported that the Viktor Leonov, which conducted similar patrols in 2014 and 2015, was off the coast of Delaware Wednesday, but typically it only travels as far as Virginia.

The ship is based with Russia’s northern fleet on the North Sea but had stopped over in Cuba before conducting its patrol along the Atlantic Coast and is expected to return there following its latest mission.

The vessel is outfitted with a variety of high-tech spying equipment and is designed to intercept signals intelligence. The official said that the US Navy is “keeping a close eye on it.”
The Leonov is a Vishnya-class spy ship, as is a Russian vessel that trailed the US ship that encountered close-flying Russian aircraft in the Black Sea on Friday.

U.S. ship changed course toward Iranians on Saturday : Iran commander | Reuters

A U.S. Navy ship changed course toward Iranian Revolutionary Guard vessels in the Strait of Hormuz on Saturday, a guard commander was quoted as saying on Wednesday while issuing a warning.

A U.S. official told Reuters on Monday that multiple fast-attack vessels from the Revolutionary Guard had come within 600 yards (550 meters) of the USNS Invincible, a tracking ship, forcing it to change direction.

But guard commander Mehdi Hashemi said the incident, the first of note between the countries’ navies in those waters since January, was the fault of the U.S. ship, telling the Fars news agency: “The unprofessional actions of the Americans can have irreversible consequences,”
