The D-design still saw the same armament but major adjustments to allocations of rooms and equipment. The design was finally chosen for a further devolpment which led to the extended D-design. The D2 was lenghtened some feet for installation of a 12,8cm twin-DP turret. A new turret for the 5,5cm twin was design, with deckpenetrating ammunitionshaft, the gun was full-auto (like the 3cm aa) now. For comparison the E-design was discussed but rejected (obsolete at draft).
The much discussed F-design was decided to get evolved into a helicoptercarrier due to its high potential.
