YOKOSUKA, Japan - The improved Los Angeles-class, fast-attack submarine USS Tucson (SSN 770) arrived in Yokosuka, Japan, Jan. 10, for a visit as part of its Western Pacific deployment.

With a crew of approximately 147, Tucson is conducting a multitude of missions and showcase the latest capabilities of the submarine fleet during the ongoing deployment.

"USS Tucson has maintained a high state of operational readiness and contributed to a sustained U.S. presence in the Western Pacific in support of our allies," said Cmdr. Ted O'Harrah, Tucson's commanding officer.

Tucson's crew has the ability to operate in varying environments and is always prepared to tackle any mission that comes their way.

"The men have worked and trained hard thus far on deployment and their performance over the past four months has met and surpassed expectations," said Master Chief Machinist's Mate John Adams, Tucson's chief of the boat.

For many of the crewmembers, this is their first time visiting Yokosuka.

"I am looking forward to sightseeing in Tokyo and possibly watching a drift racing competition," said Electronics Technician Steven Swain, a radioman onboard Tucson.
