USS "Mahan" began a Selected Restricted Availability (SRA) at the BAE Systems Ship Repair shipyard in Norfolk, Virginia on 6 January 2010. The extensive upgrades and installations received during this time focused on improving the ship's Command and Control capability. "Mahan" left the shipyard on 10 March, and completed a light-off assessment on 25 March, ending the SRA. The remainder of 2010 was dedicated to completing Basic Phase training, which had commenced prior to starting the SRA in 2009, conducting Integrated Phase training, and final repairs and installations to ensure "Mahan" was materially ready for an extended deployment. "Mahan" participated in the Amphibious Readiness Group's COMPTUEX in July, resulting in certification for maritime support operations. "Mahan"s executive officer was relieved on 17 September 2010 following an investigation and commodore's mast.
