The Calypso class comprised two steam corvettes (later classified as third-class cruisers) of the Royal Navy. Built for distant cruising in the heyday of the British Empire, they served with the fleet until the early twentieth century, when they became training ships. Remnants of both survive, after a fashion; HMSCalliope in the name of the naval reserve unit the ship once served, and HMSCalypso both in the name of a civilian charity and the more corporeal form of the hull, now awash in a cove off Newfoundland.
The class exemplifies the transitional nature of the late Victorian navy. In design, materials, armament, and propulsion the Calypsos 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 the "pure" sailing corvettes, with boiler rooms, machinery spaces, ventilators, and a flue added. Of iron and steel construction, they had coppering over timber below the waterline, as did older wooden vessels. Their armament was not in turrets or barbettes, but arranged in a central broadside battery, with the four largest guns on sponsons to give larger arcs of fire. And they had both a powerful steam engine and an extensive rig of sail. They formed the last class of sailing corvettes in the Royal Navy.[1][Note 1]
Calypso and Calliope comprise Calypso class, a successor to the successful Comus class, all designed by Nathaniel Barnaby. The vessels were screw corvettes or small cruisers, and were among the Royal Navy's last sailing corvettes. They supplemented an extensive sail rig with a powerful engine.
In profile they resembled older wooden sailing frigates, from bowsprit to stern gallery. The ports in the gallery were false, and there were no quarter galleries.[2] Other differences included a nearly straight stem, a shorter battery, and sponsoned guns on the corners of the battery. Above the decks they had a full suite of masts and spars, standing and running rigging, and square and fore-and-aft sails. The shrouds were not attached to chainplates on the outside of the hull, as in older vessels, but to the inside of the bulwarks. Interposed between the masts and rigging were the ventilators and stack of the steam plant. In plan the ships shows decks common to older sailing cruising vessels, including a poop deck at the rear, the overhang of which sheltered a wheel on the quarterdeck below. The guns were all on the highest continuous deck;[3] 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 armament of the class consisted of naval rifles – breechloaders with rifling in their bores to impart a spin and therefore stability to projectiles in flight. The Calypsos differed from the previous Comus class, as they had new 6-inch rifles in place of the 7-inch muzzleloaders and 64-pounders that originally armed the predecessor class, and 5-inch guns in a battery between the 6-inch guns. There were four 6-inch (152.4mm) breechloaders in sponsons fore and aft on each side, twelve 5-inch (127.0mm) breechloaders in broadside between the 6-inch guns, and six quick-firing Nordenfelts.[4]
The Calypsos were slightly longer than their predecessors, and displaced 390 tons more.[5] 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.[5] These compound engines could drive the ships at 13¾ knots, or 14¾ knots with forced draught.[6] 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 from marine growth, and the copper sheathing was affixed to timber as in wooden ships, but that timber was not structural, but simply encased the metal hull beneath.[7] Royal Navy corvettes had been built of iron since 1867, but the Comus class and the Calypsos were built of steel.[1]
They carried a barque rig of sail on three masts,[Note 2] including a full set of studding sails on fore and mainmasts.[8] This rig enabled them to serve in areas where coaling stations were rare, and to rely on their sails for propulsion. That flexibility made them was well-suited to distant cruising service and trade protection for the British Empire.[6]
The vessels had two complete decks, upper and lower, with poop and forecastle decks. The poop contained cabins for the captain, first lieutenant, and navigating officer, with the double wheel sheltered under its forward end. The forecastle was used for the heads 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 (38mm) thick and approximately 103 feet (31m) long. This armour was about 3 feet (0.91m) 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.[9]
Both vessels had relatively short careers with the fleet and in the 1890s were relegated to training and subsidiary duties. They were present at the 1897 Review of the Fleet, held to celebrate Queen Victoria's Diamond Jubilee.[10]
Calliope had achieved fame as the only ship to escape from the 1889 Apia cyclone, and thereafter was known as the "Hurricane Jumper". After fleet service, the vessel became a drill ship on the Tyne in 1907. After the old cruiser was discarded in 1951, the "stone frigate" (shore establishment) operating there was given the name of HMSCalliope.[11]
Calypso had a less eventful and shorter naval career than Calliope, but spent more time at sea. As part of the sail training squadron, Calypso cruised in home waters, the North Sea, and the Arctic and Atlantic oceans. In 1902, after that service ended, the ship was sent to the colony of Newfoundland, and served there as a stationary training vessel for the Newfoundland Royal Naval Reserve before and during the First World War. In 1922 the vessel was declared surplus and sold out of the service, and thereafter used as a storage hulk in Lewisporte. The Calypso Foundation, a local charity engaged in training the developmentally disabled, was named after the old training ship.[12] The ship's hull was towed away to a coastal bay and burned out. It is still there, awash in the waters of the Atlantic Ocean.[13][Note 3]

A brig is a type of sailing vessel defined by its rig: two masts which are both square-rigged. Brigs originated in the second half of the 18th century and were a common type of smaller merchant vessel or warship from then until the latter part of the 19th century. In commercial use, they were gradually replaced by fore-and-aft rigged vessels such as schooners, as owners sought to reduce crew costs by having rigs that could be handled by fewer men. In Royal Navy use, brigs were retained for training use when the battle fleets consisted almost entirely of iron-hulled steamships.
An ironclad was a steam-propelled warship protected by steel or iron armor constructed from 1859 to the early 1890s. The ironclad was developed as a result of the vulnerability of wooden warships to explosive or incendiary shells. The first ironclad battleship, Gloire, was launched by the French Navy in November 1859, narrowly preempting the British Royal Navy. However, Britain built the first completely iron-hulled warships.
In the 18th century and most of the 19th, a sloop-of-war in the Royal Navy was a warship with a single gun deck that carried up to eighteen guns. The rating system covered all vessels with 20 guns and above; thus, the term sloop-of-war encompassed all the unrated combat vessels, including the very small gun-brigs and cutters. In technical terms, even the more specialised bomb vessels and fireships were classed as sloops-of-war, and in practice these were employed in the sloop role when not carrying out their specialised functions.
Steam frigates and the smaller steam corvettes, steam sloops, steam gunboats and steam schooners, were steam-powered warships that were not meant to stand in the line of battle. The first such ships were paddle steamers. Later on the invention of screw propulsion enabled construction of screw-powered versions of the traditional frigates, corvettes, sloops and gunboats.
A screw sloop is a propeller-driven sloop-of-war. They were popularized in the mid-19th century, during the introduction of the steam engine and the transition of fleets to this new technology.
HMS Monarch was the first seagoing British warship to carry her guns in turrets, and the first British warship to carry guns of 12-inch (300 mm) calibre.
HMS Calliope was a Calypso-class corvette of the Royal Navy of the United Kingdom which served from 1887 until 1951. Exemplifying the transitional nature of the late Victorian navy, Calliope was a sailing corvette—the last such ship built for the Royal Navy—but supplemented the full sail rig with a powerful engine. Steel was used for the hull, and like the earlier iron-hulled corvettes, Calliope was cased with timber and coppered below the waterline, in the same manner as wooden ships.
