Two sailors hurt after explosion caused by rapid depressurization aboard USS Louisiana

Two sailors hurt after explosion caused by rapid depressurization aboard the Navy’s USS Louisiana ballistic-missile submarine: Authorities say problems arose during ‘routine’ test of the ship’s air system

  • Two people were injured after an explosion on the USS Louisiana at the Puget Sound Naval Shipyard near Seattle on Saturday 
  • Several people from the nearby town of Bremerton said they heard a loud boom
  • The explosion happened at midday just as a routine compartment air test was being conducted
  • Two people suffered injuries during the test and were taken to hospital 
  • Their injuries are not considered life-threatening

Two people were taken to the hospital after an explosion aboard a docked U.S. Navy vessel in Washington state Saturday.   

The incident occurred on the Navy’s USS Louisiana ballistic-missile submarine while it was stationed at the Puget Sound Naval Shipyard near Seattle, and saw two people taken to the hospital for non life-threatening injuries. 

Military authorities said the explosion was the result of rapid depressurization in one of the ship’s cabins during a ‘routine’ test of the vessel’s air system. 

Five other sailors were ultimately seen by Navy medics, but did not require medical attention.

Residents in the area said they heard a blast just after noon in the Bremerton area.

Shipyard officials have since explained the problem as a malfunction occurring  during a routine compartment air test on the Ohio-class sub. 

The vessel ‘experienced a problem’ in the forward logistics escape trunk, according to Puget Sound Naval Shipyard spokeswoman Anna Taylor. 

It led to a rapid depressurization on the 560-foot sub, which caused a loud noise. 

The incident caused a dislodged a scaffolding enclosure and “other equipment” inside the submarine, a spokesperson for the shipyard said.
