U.S. Navy leaders are recommending a sweeping list of changes in sailor training, crew requirements and safety procedures to address systemic problems across the Pacific fleet that led to two deadly ship collisions earlier this year that killed 17 sailors, according to a copy of the report obtained by the Associated Press.

A critical report scheduled to be released Thursday calls for about 60 recommended improvements that range from improved training on seamanship, navigation and the use of ship equipment to more basic changes to increase sleep and stress management for sailors.
