The Town class was a group of twenty-one light cruisers built for the Royal Navy (RN) and Royal Australian Navy (RAN).
 These vessels were long-range cruisers, suitable for patrolling the vast expanse covered by the British Empire.
 These ships, initially rated as second class cruisers, were built to a series of designs, known as the "Bristol" (five ships), "Weymouth" (four ships), "Chatham" (three RN ships, plus three RAN ships), "Birmingham" (three ships, plus one similar RAN ship) and "Birkenhead" (two ships) classes – all having the names of British towns except for the RAN ships, which were named after Australian cities.
HMS "Lyme" was a 28-gun, sixth-rate frigate of the Royal Navy.
 Originally ordered as a 24 gun ship to the draft of the French privateer "Tyger".
 The sixth vessel of the Royal Navy to bear the name, "Lyme", as well as "Unicorn" , which was a near-sister, were the first true frigates built for the Royal Navy.
 They were actually completed with 28 guns including the four smaller weapons on the quarterdeck, but the latter were not included in the ship's official establishment until 22 September 1756.
 The two ships differed in detail, "Unicorn" having a beakhead bow, a unicorn figurehead, two-light quarter galleries and only five pairs of quarterdeck gunports, while "Lyme" had a round bow, a lion figurehead, three-light quarter galleries and six pairs of quarterdeck gunports.
Two ships of the Royal Navy have borne the name HMS "Hyperion", after Hyperion, one of the Titans of Greek mythology.
 A third was planned but never completed:
An Aircraft Handler is a member of the Aircraft Handling branch in the Royal Navy of the UK Armed Forces.
 Aircraft Handlers are responsible for the safe movement, launching (taking off) and recovering (landing) of all aircraft onboard ships within the Royal Navy and some of the Royal Fleet Auxiliary.
 They are also responsible for aircraft crash rescue fire fighting duties on board Royal Navy ships and at Royal Naval Air Stations.
 The Aircraft Handling branch of the Fleet Air Arm in the Royal Navy was formed in 1945.
 Beforehand the duties of Aircraft Handlers were performed by members of other branches of the Royal Navy, many of whom transferred to the new branch upon its formation.
In Greek mythology, Hyperion ( ; Greek: Ὑπερίων , "Huperíōn " , "The High-One") was one of the twelve Titan children of Gaia (Earth) and Uranus (Sky or Heaven) who, led by Cronus, overthrew their father Uranus and were themselves later overthrown by the Olympians.
 With his sister, the Titaness Theia, Hyperion fathered Helios (Sun), Selene (Moon) and Eos (Dawn).
The C class was a group of twenty-eight light cruisers of the Royal Navy, and were built in a sequence of seven groups known as the "Caroline" class (six ships), the "Calliope" class (two ships), the "Cambrian" class (four ships), the "Centaur" class (two ships), the "Caledon" class (four ships), the "Ceres" class (five ships) and the "Carlisle" class (five ships).
 They were built for the rough conditions of the North Sea, and proved to be rugged and capable vessels, despite their being somewhat small and cramped.
The "Lion"-class battleships were a class of six fast battleships designed for the Royal Navy in the late 1930s.
 They were a larger, improved version of the "King George V" class with 16 in guns.
 Only two ships were laid down before the Second World War began in September 1939 and a third was ordered during the war, but their construction was suspended shortly afterwards.
 Their design changed several times in response to the removal of treaty restrictions on size and in light of war experience.
 None of the other ships planned were laid down, although there was a proposal to modify one of the suspended ships into a hybrid battleship/aircraft carrier with two 16-inch gun turrets and a flight deck.
 The two ships already begun were scrapped after the end of the war.
HMS "Unicorn" was a 28-gun "Lyme"-class sixth-rate frigate of the Royal Navy.
 She was originally ordered as a 24-gun ship to the draft of the French privateer "Tyger".
 The third vessel of the Royal Navy to bear the name, "Unicorn", as well as HMS "Lyme" which was a near-sister, were the first true frigates built for the Royal Navy.
 They were actually completed with 28 guns including the four smaller weapons on the quarterdeck, but the latter were not included in the ship's official establishment until 22 September 1756.
 The two ships differed in detail, "Unicorn" having a beakhead bow, a unicorn figurehead , two-light quarter galleries and only five pairs of quarterdeck gunports, while "Lyme" had a round bow, a lion figurehead, three-light quarter galleries and six pairs of quarterdeck gunports.
The Courageux"-class ships of the line were a class of six 74-gun third rates of the Royal Navy.
 Their design was a direct copy of the French ship "Courageux", captured in 1761 by HMS "Bellona" .
 This class of ship is sometimes referred to as the Leviathan"-class.
 A further two ships of the class were built to a slightly lengthened version of the "Courageux" draught.
 A final two ships were ordered to a third modification of the draught.
The Battle class were a class of destroyers of the British Royal Navy (RN) and Royal Australian Navy (RAN), named after naval or other battles fought by British or English forces.
 Built in three groups, the first group were ordered under the 1942 naval estimates.
 A modified second and third group, together with two ships of an extended design were planned for the 1943 and 1944 estimates.
 Most of these ships were cancelled when it became apparent that the war was being won and the ships would not be required, although two ships of the third group, ordered for the RAN, were not cancelled and were subsequently completed in Australia.
