HMS Bellona was a 74-gun Bellona-class third-rate ship of the line of the Royal Navy. Designed by Sir Thomas Slade, she was a prototype for the iconic 74-gun ships of the latter part of the 18th century. "The design of the Bellona class was never repeated precisely, but Slade experimented slightly with the lines, and the Arrogant, Ramillies, Egmont, and Elizabeth classes were almost identical in size, layout, and structure, and had only slight variations in the shape of the underwater hull. The Culloden-class ship of the line was also similar, but slightly larger. Thus over forty ships were near-sisters of the Bellona." Bellona was built at Chatham, starting on 10 May 1758, launched on 19 February 1760, and commissioned three days later. She was the second ship of the Royal Navy to bear the name, and saw service in the Seven Years' War, American Revolutionary War and the Napoleonic Wars.
The Dido class consisted of sixteen light cruisers built for the Royal Navy during World War II. The first group of three ships were commissioned in 1940; the second group and third group were commissioned between 1941 and 1942. A fourth group, also described as the Improved Dido, or the Bellona class, were commissioned between 1943 and 1944. Most members of the class were given names drawn from classical history and legend. The groups differed in armament and for the Bellonas, in function. The Dido class were designed as small trade protection cruisers with a secondary role with the fleet providing leaders for the destroyer screen. The Didos were designed for five turrets, with twin 5.25" high angle gun turret mountings, complex modern warships and turrets, offering shell loading, -05 to 90 degree elevation to give a dual-purpose capacity with centreline turrets with potential AA possible. The new complex turrets were unreliable when introduced and somewhat unsatisfactory, at a time the UK faced a military fight for survival. During the war the original 1939-42 Didos class required very extensive increased electric generating capacity for additional radar and RPM with electrification of turret hydraulics and in the final Bellona, HMS Diadem electric turrets While some damage was experienced initially in extreme North Atlantic conditions, modified handling avoided the problem. The fitting of the three turrets forward in A, B and C positions depended on some use of aluminium in the structure and the lack of aluminium after Dunkirk was one of the reasons for only four turrets being fitted to the first group of three, while the third group had four turrets with twin 4.5" guns. The Bellona's were designed from the start with four turrets with radar-aimed guns and greater light anti-aircraft armament.
The "seventy-four" was a type of two-decked sailing ship of the line, which nominally carried 74 guns. It was developed by the French navy in the 1740s, replacing earlier classes of 60- and 62-gun ships, as a larger complement to the recently-developed 64-gun ships. Impressed with the performance of several captured French seventy-fours, the British Royal Navy quickly adopted similar designs, classing them as third rates. The type then spread to the Spanish, Dutch, Danish and Russian navies.
Sir Thomas Slade was an English naval architect best known for designing the Royal Navy warship HMS Victory, which served as Lord Nelson's flagship at the Battle of Trafalgar in 1805.
HMS Arrogant was a 74-gun third rate ship of the line of the Royal Navy, built of Suffolk oak by John Barnard and launched on 22 January 1761 at King's Yard Harwich. She was the first of the Arrogant-class ships of the line, designed by Sir Thomas Slade.
HMS Kent was a 74-gun Bellona-class third-rate ship of the line of the Royal Navy, designed by Sir Thomas Slade and built by Adam Hayes at Deptford Dockyard and launched on 23 March 1762.
HMS Edgar was a 74-gun third-rate ship of the line of the Royal Navy, that saw service in the American Revolutionary, French Revolutionary and Napoleonic Wars. Launched in 1779, she fought in the battles of Cape St Vincent and Copenhagen, two of the major naval engagements of the wars.
The Bellona-class ships of the line were a class of five 74-gun third rates, whose design for the Royal Navy by Sir Thomas Slade was approved on 31 January 1758. Three ships were ordered on 28 December 1757, with names being assigned on 1 February 1758. Two further ships to this design were ordered on 13 December 1758, at the same time as two ships of a revised design – the Arrogant class.
HMS Superb was a 74-gun Bellona-class third-rate ship of the line of the Royal Navy, designed by Sir Thomas Slade and built by Adam Hayes at Deptford Dockyard, launched on 27 October 1760 as a sister ship to HMS Dragon.
The Hercules class ships of the line were a class of two 74-gun third rates, designed for the Royal Navy by Sir Thomas Slade.
The Dublin-class ships of the line were a class of seven 74-gun third rates, designed for the Royal Navy by Sir Thomas Slade.
The Sandwich class ships of the line were a class of three 90-gun second rates, designed for the Royal Navy by Sir Thomas Slade.
The Ramillies-class ships of the line were a class of nine 74-gun third rates, designed for the Royal Navy by Sir Thomas Slade.
The Albion-class ships of the line were a class of five 74-gun third rates, designed for the Royal Navy by Sir Thomas Slade.
The Edgar-class ships of the line were a class of three 60-gun fourth rates, designed for the Royal Navy by Sir Thomas Slade.
The Essex-class ships of the line were a class of two 64-gun third rates, designed for the Royal Navy by Sir Thomas Slade.
The St Albans-class ships of the line were a class of three 64-gun third rates, designed for the Royal Navy by Sir Thomas Slade.
The Elizabeth-class ships of the line were a class of eight 74-gun third rates, designed for the Royal Navy by Sir Thomas Slade.
The Arrogant-class cruiser was a class of four protected cruisers built for the British Royal Navy at the end of the 1890s. One ship, HMS Gladiator, was lost following a collision with a merchant ship in 1908, while HMS Vindictive saw active service in the First World War, taking part in the Zeebrugge Raid in April 1918 before being sunk as a blockship during the Second Ostend Raid in May 1918.
