The commander of the U.S. 7th Fleet in Yokosuka, Japan, has been relieved of duty, according to The Wall Street Journal.

Vice Adm. Joseph Aucoin, a three-star commander, was scheduled to retire in a few weeks.

The news of his dismissal follows the collision between the USS John S. McCainand a tanker on Monday. The vessel was damaged on its port side, and 10 sailors presumed dead. The remains of some have been found in sealed compartments on the vessel, and the search continues.

There have been four incidents involving U.S. Navy vessels in the region this year: the USS Fitzgerald collided with a container ship off the coast of Japan in June, killing seven sailors, USS Lake Champlain hit a South Korean fishing boat in May and the USS Antietam ran aground off the coast of Japan in January.

Admiral John Richardson, U.S. Navy Chief of Naval Operations, has called for a global operational pause after the last incident as well as an operational review and a comprehensive review. The comprehensive review will examine the process by which the Navy trains and certifys its forces that are foward-deployed in Japan including both tactical and navigational proficiency, and it will be in addition to the investigations that look into the details of the collisions.

The review will be headed by Admiral Philip Davidson, and Richardson says its scope will not only span the Navy, but look outside the military as well.
