S. Military and published by Independently Published. This book was released on 2018-08-04 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: The combination of negative real budget growth and unchanged operational use has stressed the resources of the United States Navy, resulting in an annual average over-budget execution of $0.77 billion per year in Navy-wide ship depot maintenance since FY2010. The Navy's active ship maintenance budget only supports 70 percent of the ship maintenance projected in FY2017; a significant portion of over-budget execution and delays has occurred with submarine availabilities. Delays to a submarine's return to the fleet results in a decrease of the overall operational availability (Ao) of already diminishing submarine force levels. In this thesis, data collected from Pearl Harbor Naval Shipyard (PHNSY) is analyzed to investigate possible factors impacting the ability of maintenance activities to complete SSN 688-class submarine maintenance availabilities as scheduled. The analysis illustrates a systematic underestimation of availability duration due to the use of outdated historically based estimates following a significant shift in maintenance strategy in 2012. Additionally, the analysis shows a significant increasing trend in the average number of man-days required to complete a job. This thesis provides a narrowed focus for future studies attempting to determine the cause of this trend. Finally, this thesis proposes a solution to the systematic underestimation of availability durations by illustrating the inherent error in the current equation and providing a notional equation to remove that error.

Book Synopsis Assessment of Surface Ship Maintenance Requirements by : Robert Button
Download or read book Assessment of Surface Ship Maintenance Requirements written by Robert Button and published by Rand Corporation. This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Department of Defense is likely to face years of declining resources as the U.S. government grapples with fiscal challenges. These challenges affect every account, including those associated with surface ship maintenance and operations. At the same time, there has been widespread concern that surface ship materiel readiness is declining due to a high pace of operations and a sense that there have been many instances of deferred maintenance. The need to balance fiscal reality and a continued need for ready ships is likely to be an ongoing challenge. At the request of the Assessment Division of the Office of the Chief of Naval Operations, this report: (1) determines the impact on long-term fleet readiness, Operational Availability (Ao), and Expected Service Life (ESL) caused by near-term reductions in Operations and Maintenance (O&M) accounts; (2) recommends potential strategies to minimize negative impacts to Ao and ESL and maintain the largest, most capable fleet possible; (3) develops a maintenance requirement concept, per ship class, that supports ESL, but allows for some risk within the maintenance strategy; and (4) defines the risks to Ao and ESL resulting from the new requirement. The methodology could be applicable to multiple ship classes.

Book Synopsis Costs of Submarine Maintenance at Public and Private Shipyards by : United States. Congressional Budget Office
Download or read book Costs of Submarine Maintenance at Public and Private Shipyards written by United States. Congressional Budget Office and published by . This book was released on 2019 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Public shipyards conduct a large majority of all submarine maintenance. Those shipyards are Navy-owned and -operated, but the Navy has been experiencing long delays—sometimes as much as several years—to obtain maintenance on its submarines at those shipyards. As a result, some submarines have missed deployments or had shortened deployments. The Navy has sent several submarines to private shipyards for overhauls in recent years but could send more. This report compares the costs of submarine maintenance at public and private shipyards. This analysis focuses on depot maintenance—specifically, Docking Selected Restricted Availability (DSRA) overhauls— for the Navy’s Los Angeles class attack submarines (SSN-688s). DSRAs are medium-sized maintenance events that last several months and occur every four to six years over the 33-year lifetime of an SSN-688 submarine. They include maintenance, repairs, and upgrades; the submarine is put into a dry dock to enable work on the hull, propulsion, and systems (which would otherwise be underwater).

Book excerpt: The United States faces major challenges in dealing with Iran, the threat of terrorism, and the tide of political instability in the Arabian Peninsula. The presence of some of the world’s largest reserves of oil and natural gas, vital shipping lanes, and Shia populations throughout the region have made the peninsula the focal point of US and Iranian strategic competition. Moreover, large youth populations, high unemployment rates, and political systems with highly centralized power bases have posed other economic, political, and security challenges that the Gulf states must address and that the United States must take into consideration when forming strategy and policy.

Book Synopsis Sustaining U.S. Nuclear Submarine Design Capabilities by :
Download or read book Sustaining U.S. Nuclear Submarine Design Capabilities written by and published by . This book was released on 2007 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. submarine eet currently numbers more than 50 fast attack submarines (SSNs) and 18 submarines built to launch ballistic missiles (SSBNs). All are nuclear powered to maximize the duration and speed of underwater operations. While the submarine eet has been decreasing in size since the end of the Cold War, it is anticipated that the U.S. Navy will sustain a force of several dozen boats into the foreseeable future. Submarines are almost continually being built to replace older ones that must be retired. As is the case with surface ships, submarines are built in classes sets of boats constructed to a common design. Designing a new class of nuclear submarines is a very large and complex endeavor, lasting 15 years or longer and requiring 15,000 to 20,000 man-years at the prime shipyard contractor alone.
