A House committee announced Wednesday it will hold a hearing to look into collisions involving the USS John S. McCain and USS Fitzgerald following a summer of deadly military mishaps that have raised questions about the readiness of U.S. forces.

The Armed Services hearing on Sept. 7 will look into underlying problems of Navy readiness that might have caused or contributed to the separate collisions, which left seven Fitzgerald sailors dead and as many as 10 dead from the McCain.
