Project history

Good ships, but deficient in heavy armament. Carlo Alberto which could be distinguished from her sister by the presence of a mainmast, was used from 1902 for Marconi's first long range radio experiments at sea. Both vessels were designed by Eng Insp Edoardo Masdea.

Ship protection

150mm belt protected full ship length and casemate, it was closed by 37mm deck.

Modernizations

None.

Naval service

In 1907-10 Carlo Alberto served as a TS for torpedo ratings and gunners, and in 1917 she began conversion, in Venice NYd, to a troop transport, the work being completed in 1917-18 in Taranto NYd. From 4.4.1918 she was renamed Zenson, being recommissioned on the same day. Vettor Pisani was used as repair ship from 1.11.1916 to 27.11.1918.
