The underwater speed will be max app. 7-8 knots.
Actually we do not have any sub right now that can dive. Freya has been decommissioned for a few months not. Kraka has a broken exhaust system, that can be repaired, but we will rather put our time into getting Nautilus ready to dive. Kraka will soon be decommissioned as well - it takes allot of time to have a sub operational!
