After a pair of crashes involving U.S. Navy ships in the Asia-Pacific killed more than a dozen people last year, the Navy's efforts to develop its leaders is receiving renewed attention.

Last week, the Navy inaugurated the College of Leadership and Ethics at the U.S. Naval War College in Rhode Island.

Seventeen sailors were killed last year in two collisions with commercial vessels involving guided-missile destroyers, the Fitzgerald in June off Japan and the John S. McCain in August as it approached Singapore.
