Make that Secretary Mabus

Navy Secretary Ray Mabus is now officially just that, sworn in to the position yesterday, according to the service. A former Mississippi governor and ambassador to Saudi Arabia, the 75th secretary took his oath of office during a ceremony at the Pentagon.

Mabus replaces B.J. Penn, who was filling the role on an interim basis following the departure of former Navy Secretary Donald Winter on March 13.

In addition, according to Mabus' spokeswoman, Navy Under Secretary Robert Work was sworn in to his post this morning. A retired Marine Corps colonel, Work was previously a naval analyst and vice president at the Center for Strategic and Budgetary Assessments.

Mabus and Work were confirmed by the Senate on Monday. During an April 28 Senate Armed Services Committee confirmation hearing, Mabus and Work pledged to improve the Navy’s acquisition workforce.
