The
Ersatz Monarch-class (
Replacement Monarch-class)
battleship was a projected new class of four battleships which were to be constructed for the
Austro-Hungarian Navy in 1914–19. Designed to replace the
Monarch-class battleships (which later became
coastal defense ships), each of the new battleships were to carry ten
35 cm (14 in) L/45 guns as their primary armament,
[1] a slight improvement over her predecessors, the
Tegetthoff class. The ships were 175.2 metres (575 ft) and were designed to displace 24,560 tonnes (24,170 long tons; 27,070 short tons).
The Austro-Hungarian Navy intended to lay down the first vessel in July 1914, but the outbreak of
World War I that month caused the Navy to postpone construction until September. Ultimately, none of the vessels were laid down and they were formally cancelled in late 1917. However, four of the 35 cm guns had been built and were transferred to the
Austro-Hungarian Army for use on the
Italian Front.
