Having made a Virginia Class it seemed right to make a full hull version as would be seen in a dockyard. This is a full hull out of the water/dry dock version of  the Virginia Class submarine of which there are currently 17 in service with the US Navy and more being built.  This is a second production run and these dont have a self supporting stand so need a dry dock or a bit of blue tack. Only just noticed this difference.   8700tons  370ft long. Length 90mm nearly 4 inches Ref  S103
