The DDX destroyer with its two Advanced Gun Systems (AGS) will provide future naval expeditionary strike groups the transformational naval surface fire support and sea based strike capabilities required for the nation's emerging 421 defense strategy.
Advanced Gun System (AGS) is a vertically loaded 155 mm cannon with a fully automated magazine. The gun will fire rounds up to 100 nautical mi with a sustained firing rate of 10 rounds per minute.
The following operational scenario depicts a expeditionary strike group executing non-combatant evacuation operation supported by the DDX. Real time operation of this scenario would take hours to complete, therefore time compression techniques are used.
