There are about nine US ships in the region, including cruisers and destroyers carrying teams that can board and search other vessels, according to the AP.
The officials spoke to the AP on condition of anonymity because they were not authorized to discuss the ship movement on the record.
The US actually began moving assets to Yemeni waters on April 19, before news broke of the apparent planned interdiction of an Iranian weapons shipment. According to a
US Navy press release on April 20th, the USS Theodore Roosevelt, an aircraft carrier, transited to the Arabian sea the day before while accompanied by a guided-missile cruiser.
The ships "have joined other US forces conducting maritime security operations in the Arabian Sea, Gulf of Aden, the Strait of Bab-el-Mandeb and the Southern Red Sea," the Navy states.
The
Bab el-Mandeb stretches between Yemen and the Horn of Africa, and is one of the world's busiest oil chokepoints. Fighting in Yemen, and recent gains by Al Qaeda and Houthi fighters, could potentially threaten open passage through the waterway, which is 18 miles across at its narrowest point.
The presence of US warships could help protect commercial waterways potentially impacted by the Yemen conflict — although American military planners now apparently hope they can also deter Iran from getting even more involved in the country.
