What happened to the 1000+ lane metres? Have the Berlins been changed to accomodate that requirement?The Canadians never seem to be all that forthcoming with this sort of info but the Cantabria and Berlin classes were the final shortlisted designs.
While I haven't been able to find any details on the Navantia proposal the Protecteur class seems to offer more capability than the standard Berlin. I would be the first to admit these claims seem pretty dodgy ... and yes it is a wikipedia page.
AFAIK the RCN competition was for an AOR, if that’s the case Cantabria makes perfect sense but convert either design to carry many vehicles and you destroy the liquid cargo capability.
