The Etna was
one the first antiaircraft cruisers build in Italy. Originally
ordered by Siam (now Thailand), it was laid down in 1939 Taksin
, equipped with six 15,2 cm guns. In 1942 the ship was taken over
by Italy and it was decided to continue it as an anit-aircarft
cruieser which also could serve as flagship. The ship was still
under construction in Trieste when it was captured by German troops
after the surrender of Italy on 10.09.1943. To prevent their use
by the Germans, the ship was sunk by the retreating Italians.
Completed about 60%, the Germans never intended to continue the
construction, after the war, it was found scuttled in Trieste
harbor, refloated and scrapped.
