3DCam - 2017 is the official out of service date for the mk3 and 3A Sea kings; even if the 2012 contract leads to full civilianisation, the RAF SAR flights won't be handed over immediately. The process is likely to take a couple of years from what I have been told and is unlikely to start until 2014 to 15 - hence the 2017 OSD.
I would like a new aircraft right now but that ain't gonna happen, shuddering along at 110 kts isn't the way to get to a job quickly.
