About Department 495 - Hull Planning Yard Engineering 

Planning Yard and Fleet Support Engineering (D495) is a multi-discipline organization responsible for supporting the current submarine fleet, which consists of delivered OHIO SSBN/SSGN, SEAWOLF, and VIRGINIA Class hulls. D495 provides operational availability and capability to the fleet through maintenance and enhancement activities. These activities include managing potential design changes to commissioned ships (i.e. Ship Alteration drawings), developing documentation for class/ship modernization, making recommendations for service life extension, and providing technical direction in support of emergent problems (i.e. Liaison Action Requests (LARs)).
