1934, Duca degli Abruzzi Class

Two light cruisers laid down. Duca degli Abruzzi and Duca d'Aosta. Evolution over the previous class but with same general layout. Beam and displacement have been increased significantly to 8000tons.

Main armament is 4 duple 152/53. Although ballistically similar to the previous weapons they are in fact different. A vertically-sliding breech block is used and the mounting elevates up to 80°. As in the previous model the loading trays move with the gun allowing loading at any angle. Under development since 1930 with the stillborn 135/54 the mounting has undergone a few designs iterations as problems with ammunition supply were noticed. The sea trials onboard the cruiser Quarto were especially useful. Another change to the mounting are the increased train and elevation rates for increased usefulness against small craft and the new generation monoplanes. Other armament consists of 47/62 in the standard quadruple mountings, and 6 duple stablised twin 25mm mountings.

Machinery is similar to the previous class but with output being slightly increased.

Armour consists of a 100mm thick external inclined belt and considerable deck armour. The chosen range of engagement over 150-200hm when performing escort duties dictated the need for increased deck armour against 150mm and 210mm shellfire.

Alberto da Giussano Rebuilt 1934

Da Guissano will be rebuilt into an anti-aircraft cruiser mounting the 100/65 gun in 8 mountings. The lack of a larger anti-aircraft weapon resulted in the choice of the 100/65 which is distinctly lacking against surface targets. However it is an excellent AA gun. The trade off was thought to be acceptable. The arrangement of the mountings provides reasonable arcs of fire. Also included in the reconstruction was a newer, larger superstructure and new engines.

Something more along the lines of a traditional cruiser rather than the previous abberrations. Reasonable size with a big hull to put lots of stuff. Its slightly cramped at the moment due to the aircraft facilities but they were thought to be needed, and it'll make a good cinema. Still haven't really decided on the main armament, I might go for triples instead, but Italy does have a lot more experience with quadruple mountings and the extra firepower might be needed. Armament is rounded out by the standard 100/65 and new, roomier quadruple 47mm mountings. No torpedoes from lack of space mainly, but probably of limited utility as well. Everything else is average to good.
