 navy. In design, materials, armament, and propulsion the Calypso show evidence of their wooden sailing antecedents, blended with characteristics of the all-metal mastless steam warships which followed. Their appearance and layout was similar to "pure" sailing corvettes, with boiler rooms, machinery spaces, ventilators, and a flue added. Of iron and steel construction, they had coppering

 below. The guns were all on the highest continuous deck; the battery was shorter than on wooden vessels with full-length gun decks, as the class carried fewer (although more powerful) guns than corvettes and frigates in the classic age of sail; all guns were carried in the waist of the ship, between the poop and forecastle.

The Calypsos differed however from the previous Comus class, as they had new 6" rifles in place of the 7" muzzleloaders and 64-pounders that originally armed the predecessor class, and 5" guns in a battery between the 6" guns.

The Calypsos were slightly longer than their predecessors, and displaced 390 tons more. Their engines were of 4,023 i.h.p., over 50% more powerful than those of their nine predecessors, which gave them one more knot of speed. These compound engines could drive the ships at 13¾ knots, or 14¾ knots with forced draught. The hulls of these vessels were of course adapted for the screw driven by their reciprocating steam engines. In common with older vessels, they were coppered to reduce fouling

 and working space for the cables. Between these was the open quarterdeck in the waist of the ship, on which the battery was located. Under the lower deck were spaces for water, provisions, coal, and magazines for shell and powder. Amidships were the engine and boiler rooms. These were covered by an armoured deck, 1.5 inches (38 mm) thick and approximately 103 ft (31 m) long. This armour was about 3 ft (120 cm) underneath the lower deck, and the space between could be used for additional coal bunkerage. The machinery spaces were flanked by coal bunkers, affording the machinery and magazines some protection from the sides. The lower deck, above the machinery spaces, was used for berthing of the ship's company; officers aft, warrant and petty officers forward, and ratings amidships, as was traditional. The tops of the coal bunkers, which projected above deck level, could be used for seating on one side of the mess tables, which were arranged fore-and-aft. The living spaces were well-ventilated and an improvement over prior vessels.
