Your guess as to what

1500 lbs at 200 knots. Does a dud torpedo really knock people over in a 20,000 ton submarine? 1500 lbs is like me throwing my golf cart at a sub.

Wouldn't it have to be another sub?

Update: Guam's drydocks are gone. That is a serious problem considering the tensions in the Indo-Pacific and the South China Seas.

http://Hurt USS Connecticut Highligh... Key Guam Base

Sixteen years ago, the attack submarine USS San Francisco (SSN-711) struck a seamount, surfaced, and went to the island of Guam, America’s westernmost outpost in the Pacific Ocean. After the hurt sub arrived at Guam’s Apra Harbor, the Los Angeles class submarine went into a local dry dock, where shipyard workers made the damaged ship safe enough to make a 6,500-mile journey home to Puget Sound Naval Shipyard for permanent repairs.

History, it seems, is repeating itself. Earlier this month, after the Seawolf class attack submarine USS Connecticut (SSN 22) struck an underwater object, the damaged sub surfaced and made for America’s safe-haven at Guam.


But this time, the reception of the USS Connecticut is going to be a little different.


Today, the only thing Guam offers the USS Connecticut is privacy. The dry dock that supported the USS San Francisco is gone. A handful of Guam-based ship repair workers are available, but they are only certified to conduct basic, pier side repairs. Only the specialists aboard a set of 42-year-old submarine tenders can help.



If the damage to the sub is severe, it will be a real struggle to patch up the USS Connecticut enough so it can make a safe transit to the Navy shipyards in either Hawaii or Puget Sound—over 6,500 miles away.



The Navy’s lack of ship repair support in the central Pacific is a serious matter.

It is most likely that it just struck an uncharted underwater terrain feature.

Would passive sonar pick that up?

Well, flip a coin. The Navy likes your version. Good call (as far as we'll probably hear).

USS Connecticut: Navy investigation finds US nuclear-powered submarine hit uncharted underwater mountain.....

McAuliffe’s decision to have Weingarten speak at rally mocked by Republicans



A US nuclear-powered submarine that struck an underwater object in early October had hit an uncharted underwater mountain, an investigation found, forcing it to head from the South China Sea to Guam for repairs.


The USS Connecticut had been operating in the contested waterway when it struck the object on October 2, but it was unclear at the time what it had hit.


"The investigation determined USS CONNECTICUT grounded on an uncharted seamount while operating in international waters in the Indo-Pacific region," a 7th Fleet spokesperson told CNN in a statement. US 7th Fleet operates in the Western Pacific and Indian oceans.


The command investigation for the USS Connecticut has been submitted to Vice Adm. Karl Thomas, the commander of 7th Fleet, for his review, according to the statement. Thomas will decide whether "follow-on actions, including accountability, are appropriate."

Navy sacks USS Connecticut leadership following underwater crash.....

The U.S. Navy has relieved the leaders aboard the USS Connecticut, a nuclear submarine that crashed into an “uncharted seamount ” last month, of their command.


A spokesperson for the 7th Fleet told the Washington Examiner on Thursday that Vice Adm. Karl Thomas, commander of the fleet, relieved Cmdr. Cameron Aljilani as commanding officer, Lt. Cmdr. Patrick Cashin as executive officer, and Master Chief Sonar Technician Cory Rodgers as chief of the boat.


Capt. John Witte will assume duties as interim commanding officer, while Cmdr. Joe Sammur will assume duties as interim executive officer, and Command Master Chief Paul Walters will assume duties as interim chief of the boat.


The USS Connecticut is currently in Guam undergoing a damage assessment and will return to Bremerton, Washington, for repairs, according to the fleet.....snip~
