Description
There is a requirement for the Maritime Command & Control, Targeting, Navigation, and Communications Team (C2TNC) within Sense, Decide and Communicate (SDC) to provide obsolescence recovery for the Platform Data Management System 4 (PDM 4) fitted to Vanguard Class Submarines. PDM In-Service Support is currently provided through contract CSA/3049. PDM4 has been in operation since the early 1990s with an expected in-service period until 2015. The original Out of Service Dates (OSD) has been extended by up to 100%, and no provision of additional stores was made when the OSDs were extended. As a result, work is now required to address the high-risk obsolescence issues, where there are low stores and items which require regular Survey and Repair. Failure to do this will adversely impact the operational capability of the CASD Vanguard Class Submarines. Currently the two main areas of concern are (1) Power Supply Units (PSUs) of which there are three variants and (2) PEC SIOs. Both items are critical to the safe operation of PDM4.
