My new ship under construction at SHI is DP class 3, with a Kongsberg DPC-2 (two controllers) forward and a DPC-1 aft, in the ECR (one controller.) The sister ships have a DPC-3 forward (three controllers), and DPC-1 aft, which is what I’m used to on other ships.

The one Class 2 ship I was on only had a Kongsberg DPC-3 forward with no fire back up.

Any idea why I only have two controllers forward? I remember the Pathfinder class had three controllers forward but in two different rooms. What do the other SHI ships out there have? Unfortunately Kongsberg works for the shipyard and I have had no contact with them.
