HMS Pylades was the sole member of the Pylades class of first-class screw corvettes that served in the Victorian Royal Navy. Pylades was a development of the previous Highflyer class with a greater beam. The vessel served under two commanders who later became admirals, Captains Arthur Acland Hood and Edwin Tennyson-d'Eyncourt. A third commander was Captain Michael de Courcy, remembered in the name of De Courcy Island, one of the Gulf Islands off the coast of British Columbia along with Pylades Island, which is named for the corvette. In 1855, Pylades served in the Baltic Sea during the Crimean War. In 1859, the vessel was the last Royal Navy warship to visit the San Juan Islands during the San Juan Boundary Dispute. In 1863, the ship's presence helped diffuse the Chesapeake affair that could have led to the British Empire joining the American Civil War. After serving across the British Empire, the ship was decommissioned and sold to be broken up in 1875.

In May 1850, the Surveyor of the Navy Baldwin Walker was managing the transition from sail to steam across the navy at the time of budget constraints. The first fifth-rate screw frigates had just been ordered, the Highflyer class, which would be later rerated as first-class corvettes. A follow-on order of four frigates of 1,500 bm was made. However, this was amended to one frigate, Aurora, and the remaining three vessels were downgraded to smaller corvettes.[1] One these was Pylades, originally ordered on 24 December 1852 as an additional Highflyer. The design was revised before being laid down, with a wider beam, and the new vessel became the sole member of the Pylades class.[2]

The corvette had an overall length of 192 ft 9 in (58.75 m) and a length between perpendiculars of 165 ft 0.5 in (50.30 m), with a beam of 38 ft 4 in (11.68 m) and design draught of 19 ft 7 in (5.97 m). Design displacement was 1,956 long tons (1,987 t) and 1,268 bm although the vessel was 1,267 bm as completed. The ship was equipped with a horizontal single expansion marine steam engine built by John Penn and Sons that had two cylinders, each with 55 in (1.4 m) bore and 5 ft (1.5 m) stroke. Rated at 350 horsepower (260 kW) and 1,106 indicated horsepower (825 kW), the engine drove a single shaft, to give a design speed of 10.119 knots (19 km/h; 12 mph).[2] The screw had two blades, which caused the stern to oscillate while under steam. The engine was complemented by a ship-rig. Under sail, the vessel could attain 7 knots (13 km/h; 8.1 mph).[3]

At launch, Pylades carried a heavier armament than any other corvette in the navy at the time.[4] The main weapons consisted of twenty 8 in (200 mm) 42 cwt[Note 1] 32-pounder smooth bore muzzle loading (SBML) guns mounted on broadside trucks. Ten were mounted to each side. A single 10 in (250 mm) 95 cwt 68-pounder SBML pivot gun was mounted on the deck.[2] Although installed at the bow, the pivot gun was flexible, being designed to be mounted both at the bow and stern and to fire both shells and shot.[4] The ship had a complement of 250 officers and ratings.[2]
