Warning: Calibre too large for machine gun - 3rd battery

Designed to exploit the new turbine technology, the ship makes use of 8 boilers, 2 fully coal fired, the rest oil-sprayed coal (so 25%+(75*0.9))=92.5% coal

Range is 3 weeks at 10 knots, with a 10% reserve

A protected cruiser, armor is 90mm on the slopes and 30mm on the flat.
Heavily armed, I had some misgivings about the heavy guns on a small hull, but she's larger than the PG-Erie (4x6", 2000t) class and far lighter armed than the Etna class PCs of 3530t.

25t- The ships are fitted with long range wireless
16t- fitted with 2 broadside torpedo tubes on each side- with 16 torpedoes.
40t- mines on fantail.

ed: noticed I originally posted version without superimposed guns, posted the correct version, same tonnage.
