Ship project history


Wooden-hulled. Copies of French batteries employed in the Crimean War. Intended to carry 16 guns but two guns were deleted to keep down the draught. Although complete as single-screw, Meteor and possibly others were quickly altered to triple-screw, with wing shafts presumably driven through a belt arrangement. Aetna was fired and launched herself 3/5/1855 (two days earlier than planned date) when she was nearly complete, but her remained incomplete and later BU on river bank.

Ship protection

Modernizations
