Being 20.12m longer and 2.12m wider these upgunned versions of the Kaiserin Augusta class shouldn't have a NEDS problem. The TT are on the sides forward of the midships 15cm guns. Also included are 30 mines for improvised minelaying (Offensive or defensive). At a little over 29 1/4 knots they can operate as GTB leaders, or screen for the fleet.
