A Russian nuclear-powered attack submarine armed with long-range cruise missiles operated undetected in the Gulf of Mexico for several weeks and its travel in strategic U.S. waters was only confirmed after it left the region, the Washington Free Beacon has learned.

It is only the second time since 2009 that a Russian attack submarine has patrolled so close to U.S. shores.

The stealth underwater incursion in the Gulf took place at the same time Russian strategic bombers made incursions into restricted U.S. airspace near Alaska and California in June and July, and highlights a growing military assertiveness by Moscow.

The submarine patrol also exposed what U.S. officials said were deficiencies in U.S. anti-submarine warfare capabilities—forces that are facing cuts under the Obama administration’s plan to reduce defense spending by $487 billion over the next 10 years.

The Navy is in charge of detecting submarines, especially those that sail near U.S. nuclear missile submarines, and uses undersea sensors and satellites to locate and track them.

The fact that the Akula was not detected in the Gulf is cause for concern, U.S. officials said.

The officials who are familiar with reports of the submarine patrol in the Gulf of Mexico said the vessel was a nuclear-powered Akula-class attack submarine, one of Russia’s quietest submarines.

A Navy spokeswoman declined to comment.

One official said the Akula operated without being detected for a month.

“The Akula was built for one reason and one reason only: To kill U.S. Navy ballistic missile submarines and their crews,” said a second U.S. official.

“It’s a very stealthy boat so it can sneak around and avoid detection and hope to get past any protective screen a boomer might have in place,” the official said, referring to the Navy nickname for strategic missile submarines.

The U.S. Navy operates a strategic nuclear submarine base at Kings Bay, Georgia. The base is homeport to eight missile-firing submarines, six of them equipped with nuclear-tipped missiles, and two armed with conventional warhead missiles.

“Sending a nuclear-propelled submarine into the Gulf of Mexico-Caribbean region is another manifestation of President Putin demonstrating that Russia is still a player on the world’s political-military stage,” said naval analyst and submarine warfare specialist Norman Polmar.

“Like the recent deployment of a task force led by a nuclear cruiser into the Caribbean, the Russian Navy provides him with a means of ‘showing the flag’ that is not possible with Russian air and ground forces,” Polmar said in an email.

The last time an Akula submarine was known to be close to U.S. shores was 2009, when two Akulas were spotted patrolling off the east coast of the United States.
