In this CNA Interactive Software document, we present the update of our Integrated Ship Database ISDB for the third quarter of calendar year 2012. In this version of the ISDB, as in the previous ones, we bring together data on naval ships from several different online government sources into a single combined database tool. The ISDB makes ship data readily accessible for analysis and reporting. With the database, you can see the makeup of the Navys Battleforce. You can find where ships are in their life cycle authorized by Congress, under construction, in commissionin service, in reserve, leased or loaned, stricken from the Register, or disposed. This work is being conducted as part of CNAs Historic Fleet Employment Database Project, sponsored by the Deputy Chief of Naval Operations for Operations, Plans, and Strategy N3N5. Since our initial version in 2005, we have published 26 quarterly updates. They are all available online on the Integrated Ship Database page of CNAs website www.cna.org. In the first section of this document, we present an overview of the ISDB. We tell you where to find the database online and how to access it. Then we show how the Microsoft Excel database file is organized according to worksheet tabs for documentation, database navigation, data tables, and pivot tables for display and analysis. If you are looking for details, please refer to the original 2005 users manual and to the fourth quarter 2011 update. In addition, the documentation of the second quarter 2012 update discusses the changes we made due to the Military Sealift Commands MSC organizational realignment of 2012. After the overview, we discuss changes in the database because of modifications to the Naval Vessel Register NVR, the MSC Ship Inventory, and the Maritime Administrations MARAD National Defense Reserve Fleet NDRF Inventory between July 1 and September 30, 2012. Finally, we present ship counts and inventory summaries as of September 30, 2012.
