[not verified in body] USS Montpelier was the first submarine to launch Tomahawk cruise missiles in Operation Iraqi Freedom.

She would go on to fire all 20 missiles earning her a "clean sweep" under the command of CDR William J. Frake.

On 27 May 2004 Montpelier went through an 18-month Depot Modernization Period (DMP) at Portsmouth Naval Shipyard in Kittery, Maine.
