From public information sources:
Ingalls Shipbuilding is located in Pascagoula, Mississippi on 800 acres of the most important real estate in America. With 11,500 employees, Ingalls is the largest manufacturing employer in Mississippi and a major contributor to the economic growth of both Mississippi and Alabama. Their 81-year legacy of shipbuilding has proven they have the talent, experience and facilities to simultaneously build more classes of ships than any other shipyard in America.
Ingalls is the builder-of-record for 35 Aegis DDG 51 class guided missile destroyers, LHA 6 class large deck amphibious ships, National Security Cutters for the U.S. Coast Guard, and the sole builder of the Navy’s fleet of San Antonio (LPD 17) class amphibious assault ships.
Originally established in 1938, the shipyard merged with Newport News shipyard in Virginia on March 31, 2011, and now forms the largest military shipbuilder in the United States. During World War Ingalls built commercial and Liberty Ships. In 1957 the shipyard won a contract to build 12 nuclear submarines, but today all nuclear submarines are built by either General Dynamics Electric Boat in Groton, Connecticut, or Newport News shipyard with is part of Huntington Ingalls.

The navy recognizes that training is expensive and critical to maintaining force readiness. The process for developing and gaining approval of a training program for new system is grueling and time-consuming. It’s not unusual for a training program implemented to support a new system to take five years of development. Final approval for a navy course is with the Deputy Chief of Naval Operations for Manpower Personnel and Training (DCNO), who is the second most senior naval officer.
To gain DCNO course approval, the navy program office managing acquisition of the new system must account for all training aids including the classroom facilities needed to support those training aids, do front-end and job task analysis, develop the curriculum, pilot the course at least once and capture all review comments (red-lining), and develop a manpower analysis of the number of instructors, support personnel required to support the course, and a five-year projection of students expected to attend the new course.
At the time I attended Instructor Training School and taught at SubTrafac the navy surface training program used the “110” standard. This standard defined the curriculum requirements for gaining formal navy approval of a training program. The submarine service of that era used the OD45519 standard, which was similar to the 110 but had more rigorous requirements for learning objectives and curriculum materials. Both standards specified format requirements for all training material such as visual learning aids, proctor guides, test banks, student training handouts, and the curriculum along with a train-the-trainer curriculum.
The 110 and OD45519 standards were paper-based systems. When I was teaching at SubTraFac in the mid-1980s micro–computer-based word processors were just becoming commercialized.
In the 1980s the navy began development of the Authoring Instructional Materials (AIM), a software management system consisting of a set of commercial and government software for the development and design of training curricula and instructional content. Today AIM is the standard tool for managing and archiving all navy instructional materials. AIM comprises the toolsets AIM I, developed for the Personal Performance Profile training approach and AIM II, developed for the Task-Based training approach. In practice, AIM I is commonly used for the surface navy training and AIM II is used for submarine training. At some point in the future the navy expects to standardize on AIM II.
AIM I and AIM II were first released between 1987 and 1997. An updated version of AIM was developed between 2006 and 2012. According to the Naval Air Warfare Center Training Systems Division (NAWCTSD), which manages AIM, the system has been able to reduce the “number of hours spent for development of new training materials by as much as 25%, and reduce maintenance of existing materials by as much as 50%” over the former paper-based curriculum systems.
One major benefit of AIM II is its capacity to store training content on a SQL server, serving as a relational database for managing the relationships between instructional material elements. Training material content is available as PDF, XML and HTML, which improves the ability to cross-utilize information in a variety of technical material (maintenance manuals, operational manuals, etc.). In 2009, Silber and Foshay estimated there was 30,000 hours of navy instructional material archived in AIM.
