Naval Surface Warfare Center Crane Division Naval Surface Warfare Center Crane Division is the principal tenant command located at Naval Support Activity Crane . NSA Crane is a United States Navy installation located approximately southwest of Bloomington , Indiana and predominantly located in Martin County , but small parts also extend into Greene and Lawrence counties . It was originally established in 1941 under the Bureau of Ordnance as the Naval Ammunition Depot for production , testing , and storage of ordnance under the first supplemental Defense Appropriation Act . The base is named after William M . Crane . The base is the third largest naval installation in the world by geographic area and employs approximately 3300 people . The closest community is the small town of Crane , which lies adjacent to the northwest corner of the facility . Operations . With an increasing demand in the 1990s and 2000s by the U . S . military for bases to support multiple functions rather than being sole - purpose installations , Crane has taken on a broad variety of development and support operations . These include expeditionary warfare systems , fleet maintenance and modernization , radar , power systems , strategic systems , small arms , surface and airborne electronic warfare , night vision system s , and undersea warfare systems . Crane is also involved in systems development for the upcoming DD ( X ) class of destroyer for the U . S . Navy and the Littoral Combat Ship .

The Maritime Electronic Warfare Systems Division models a systems engineering sustainment system that automates Electronic Warfare ( EW ) Systems sustainment activities . The model is created using the IBM Rational Rhapsody tool using the SysML modeling language and DoD Application Framework ( DoDAF ) . The sustainment model implements life - cycle activities including logistics delays based on real or proposed replacement part reliabilities , quantities , and locations , along with workflows and processes to support a performance - based sustainment ( PBS ) solution for Electronic Warfare Systems . Using SysML and DoDAF , the interactions between Crane employees , automated tools , the Electronic Warfare systems , and data to accomplish PBS are simulated . The Maritime Electronic Warfare Systems Division provides modeling and simulation for shipboard Electronic Warfare ( EW ) Systems . Scenarios have been constructed to characterize the effects of various threats on EW systems and to develop technology for increasing system performance . Antenna patterns measured in the anechoic environment are used to both enhance models and validate simulations . Special Missions .

The Small Arms Weapons Systems Division utilizes a weapon shock simulator to augment live - fire on weapon accessories and other weapon mounted electronics to ensure proper survivability . Measured shock profiles from actual weapons are used with the simulator to test the survivability of batteries , electrical connections , and optical components . This division also uses a six - axis platform that simulates sea states for testing auto - tracker software . The Electro - Optic Technology Division uses modeling tools in a number of applications . Examples include using a variety of commercially available tools to do the following : Additional modeling capabilities within the Special Missions Focus Area use common modeling tools ( i . e . Finite Element Analysis , MATLAB , COMSOL , etc . ) as well as tools developed within the government to better understand electro - optic phenomena , warfighter technology applications , benefits and trade spaces of new technologies , etc . History . In the late 1940s an ammunition quality evaluation unit was added by the Bureau to expand its quality control system . As the complexity and sophistication of weapons increased in the 1950s and 1960s , Crane ’ s activities , capabilities and expertise expanded in scope under the newly formed Bureau of Weapons to include small arms , sonobuoy surveillance , microwave tubes , POLARIS missile s and other scientific and engineering support to the Bureau . In the 1960s , Crane came under the command of the newly established Naval Ordnance Systems Command and began providing technical support for weapons systems including logistics , in - service engineering , repair , overhaul , and design . In the 1970s Crane ’ s support began to include batteries , rotating components , electronic components , failure analysis , and standard hardware and new technologies related to night vision systems . In 1974 , Crane came under the Naval Sea Systems Command that was established from the merger of the Naval Ordnance Systems Command and Naval Ship Systems Command . Shortly after in 1975 , Crane ’ s name was changed to the Naval Weapons Support Center that more accurately reflected the true function of the installation . In 1977 , a major change occurred with the designation of the United States Army as the single - service manager of conventional ammunition . This resulted in the establishment of the tenant command , Crane Army Ammunition Activity ( CAAA ) that took over the loading , assembly and storage of ammunition at the installation . CAAA and Crane ’ s strong partnership continues today . In 1992 , Crane ’ s name was changed to the Crane Division , Naval Surface Warfare Center when the warfare centers were established under the related systems commands . Today grown from its ordnance roots , Crane is recognized world wide as a modern and sophisticated leader in diverse and highly technical product lines . In 2005 , the Base Realignment and Closure Commission recommended to retain most existing operations at Crane , with weapons and armaments research , development and acquisition , and test and evaluation , except gun / ammunition , combat system security , and energetic materials to Naval Air Weapons Station China Lake . This resulted in a net loss of 672 civilian jobs from the base Tenants . Naval Support Activity Crane hosts a number of different commands and divisions . These are : Geography . The base is the third largest naval installation in the world , comprising approximately of territory . Lake Greenwood , an lake , is entirely encompassed by the base . Reconstructive White Oak wood for the is harvested from this base from a grove of trees known as " Constitution Grove " . Time Zone . Most of Crane sits in Martin County . When the rural county voted to switch over to the Central Time Zone during Indiana ' s 2006 conversion to daylight saving time , it isolated Crane from the counties in which most of its workforce resided . After a year , the county petitioned the Department of Transportation and a move back to the Eastern Time Zone was approved .
