WASHINGTON — U.S. Navy Secretary Carlos Del Toro has named Meredith Berger to perform the duties of the undersecretary of the Navy, effective Wednesday.

Berger, who is serving as assistant secretary of the Navy for energy, installations and environment, “will relieve” James Geurts, who is set to retire this week, the service said.

Geurts has performed the duties of undersecretary since February. He joined the Navy in December 2017 as assistant secretary for research, development and acquisition.
