Trident Missile Launch & Emergency Blow

This is video from Petty Officer 2nd Class Beeghly
Dan Beeghly was on the USS Newport News (SSN 750) following a six-month deployment to the North Atlantic and Central Command Theater of Operations where they conducted joint operations with Allies and provided direct support to the global war on terrorism. During that mission Dan attained his sonar supervisor status and earned a distinguished service metal for his personal effort during a particular part of their mission when he resolved a serious problem with the sonar towed array.

The USS Newport News is a Los Angeles Class fast-attack submarine.

I did not shoot this video.
