## Highlights

This report responds to House Report 111-491 to accompany a bill for the National Defense Authorization Act for Fiscal Year 2011 (H.R. 5136). The House Report noted that according to the environmental impact statement for the proposed homeporting of additional ships at Naval Station, Mayport, Florida, homeporting of a nuclear-powered aircraft carrier would result in temporary surges of maintenance employees associated with the 3-year depot-level maintenance cycle for the aircraft carrier. The homeporting of the aircraft carrier at Mayport is projected to begin in fiscal year 2019. Also, the House report raised questions about the potential impact that the additional depot-level workload would have on the sustainability, efficiency, capabilities, and stability of the maintenance employees who would travel from Navy depots to Mayport to perform the maintenance. To examine these issues, the House report directed GAO to provide an assessment of the readiness and cost impacts of the aircraft carrier homeporting and maintenance at Mayport on the Navy's traveling workforce. In response, our objectives were to determine the extent to which (1) the Navy has identified potential workforce-related costs associated with the planned move and used cost-estimating best practices to do so and (2) the readiness of the traveling workforce may be affected by having an aircraft carrier homeported in Mayport, and any mitigation measures the Navy has planned and implemented to address any potential impact.
