The USS John Warner submarine fired Tomahawks while submerged.
The US, France, and the UK conducted missile strikes on Syrian government compounds on Friday.
On Monday, the Pentagon released short videos of Tomahawks being fired from the four US Navy ships that conducted the strikes.
The Tomahawks fired by the USS John Warner were released underwater since the Warner is a Virginia-class attack submarine, which was recently commissioned in 2015.
The Higgins and Laboon are destroyers, and the Monterey is a cruiser — they all fired Tomahawks above water.
