The worst way to determine the position of a previously uncharted seamount is to run into it underwater. That is apparently what happened to the Seawolf-class attack submarine, USS Connecticut, when it hit an object while submerged on October 2.
“The investigation determined USS Connecticut grounded on an uncharted seamount while operating in international waters in the Indo-Pacific region,” 7th Fleet spokesperson Cmdr. Hayley Sims told USNI News in a Monday afternoon statement following an earlier version of this post. “Commander, U.S. 7th Fleet will determine whether follow-on actions, including accountability, are appropriate.”
