Project history

With the construction of the Monarch class, Austria embarked on a new path with Siegfried Popper, the new Director of Naval Construction. For the first time genuine turrets were used, but like all Austrian warships, because of the budget limitations, they were too small to be efficient, well-balanced battleships, and were officially designed as Coast Defence Ships.

Ship protection

The belt had 77.7m length (83% of ship length), starting from the stem, and extended from 1.2m under to 0.9m above wl. It consisted of two strakes: upper, 270mm amidships, 200mm abreast the aft barbette and 150mm between the stem and fwd barbette; and lower, tapered from 220mm to 140mm at lower edge amidships, tapered from 160mm to 80mm at lower edge abreast the aft barbette and 150mm between fwd barbette and the stem. Aft ends of the belts were closed by 200mm bulkhead. Flat steel deck had 40mm between the stem and aft barbette and was connected with upper edge of the belt. Aft part of the ship was protected by 60mm lower deck. Upper belt between barbettes was 2.42m wide and had 60mm thickness, its ends were closed by 200mm bulkheads. 15cm casemate had 80mm vertical and 12mm horizontal protection. Main and aft CTs had 220mm sides. Barbettes had 220mm protection over the upper deck and 160mm between upper and main decks. Turrets had 250mm protection.

Naval service

Monarch had a mutiny on board in February 1918 while in Cattaro harbour. From April 1918 she was accommodation ship of the submarine base, and she was allocated to Great Britain as war reparation, and scrapped in Italy. Wien was sunk during the night of 9.10 December 1917 off Trieste by the Italian MTB MAS15 under the command of Luigi Rizzo. Budapest was decommissioned in March 1918 to serve as accommodation ship for the Pola submarine base. In May/June 1918 a 38cm/17cal howitzer 38cm Haubitze M.16  was installed instead of No 1 turret for a planned coastal bombardment which never took place. In 1920 she was allocated to Great Britain and scrapped in Italy.
