The "Marathon"-class cruiser was a class of second class cruiser of the Royal Navy ordered under the naval programme of 1887.
 The class was a smaller version of the "Mersey" class (lead ship - HMS "Mersey" ).
USS "Wichita" (CA-45) was a unique heavy cruiser of the United States Navy built in the 1930s.
 The last American cruiser designed to meet the limits of London Naval Treaty, she was originally intended to be a "New Orleans"-class heavy cruiser, accordingly with the maximum main armament of three triple 8 in gun turrets.
 These were instead placed on an improved hull derived from the "Brooklyn"-class light cruisers, with increased armoring.
 This design would go on to form the basis for the later World War II-era heavy cruisers such as the "Baltimore"-class cruiser s.
 The ship was authorized by the 1929 Cruiser Act, laid down at the Philadelphia Naval Shipyard in October 1935, launched in November 1937, and commissioned into the US Navy in February 1939.
Between the 1870s and 1910s, the Austro-Hungarian Navy built a series of cruisers of various types, including small torpedo cruisers, protected cruisers, fast scout cruisers and large armored cruisers.
 The first modern cruisers were the three "Zara" class begun in the late 1870s; a fourth vessel, "Lussin" , followed in the early 1880s.
 These ships proved to be unsatisfactory in service, and so to gain experience building effective vessels, the Navy ordered the two "Panther"-class cruiser s from Britain.
 These were used as the basis for the domestically-built "Tiger" .
 Toward the end of the 1880s, the Navy shifted from building small torpedo cruisers to larger protected and armored cruisers, the first of which were the two "Kaiser Franz Joseph I"-class cruiser s.
 These provided the basis for the armored cruisers "Kaiserin und Königin Maria Theresia" , "Kaiser Karl VI" , and "Sankt Georg" , built between 1891 and 1905.
The Spanish Armada (Spanish: "Grande y Felicísima Armada" , literally "Great and Most Fortunate Navy") was a Spanish fleet of 130 ships that sailed from La Coruña in August 1588, under the command of the Duke of Medina Sidonia with the purpose of escorting an army from Flanders to invade England.
 The strategic aim was to overthrow Queen Elizabeth I and her establishment of Protestantism in England, with the expectation that this would put a stop to English interference in the Spanish Netherlands and to the harm caused to Spanish interests by English and Dutch privateering.
The AN/SPS-40 is a United States Navy two-dimensional, long range air search radar that is capable of providing contact bearing and range.
 It was used on "Perth"-class destroyer s, "Charles F. Adams"-class destroyer s, "Spruance"-class destroyer s, "Belknap"-class cruiser s, "Leahy"-class cruiser s, "Knox"-class frigate s, "Bronstein"-class frigate s, "Hamilton"-class cutter s, "Raleigh"-class amphibious transport dock s and many other ship classes.
 Its "basket" antenna with the over-the-top feed line was a familiar sight throughout the Navy even into the late 1980s.
 It was replaced by the AN/SPS-49 on newer ships and on ships that received the New Threat Upgrade.
The 15.5 cm/60 3rd Year Type (60口径三年式15.5cm3連装砲 , 60 kōkei sannenshiki 15.5 centi sanrensōhō ) was a dual-purpose naval gun used by the Imperial Japanese Navy on the "Yamato"-class battleship s as secondary armament in four triple turrets, the "Mogami"-class cruiser s in five triple turrets, the "Tone"-class cruiser s in five triple turrets (The Mogami & Tone class were later converted to five twin 20 cm/50 3rd Year Type naval gun turrets) and on the light cruiser "Ōyodo" in two triple turrets.
 They were also deployed on 60° single mounts as coastal defense guns in the Tokyo Bay area.
 Construction was of the monobloc type with autofretting and used a Welin breech block mechanism which could be operated either hydraulically or by hand.
 Their slow rate of fire, limited elevation and slow traverse made them unsuitable for the AA role, but they were an excellent anti-ship weapon.
HMS "Effingham" was a "Hawkins"-class heavy cruiser of the Royal Navy.
 She was commissioned at Portsmouth in 1925, having had her construction halted for several years following the end of the First World War in 1918.
 She was named after Lord Howard of Effingham, one of the leaders of the fleet that defeated the Spanish Armada in 1587.
 Completed in 1925, the vessel saw action during the Second World War and was escorting a convoy to Norway in 1940 when she ran aground.
 The crew was evacuated and the cruiser destroyed by a torpedo from an accompanying destroyer.
The "Zara" class was group of four heavy cruisers built for the Italian "Regia Marina" (Royal Navy) in the late 1920s and the early 1930s.
 The class comprised the vessels "Zara" , "Fiume" , "Gorizia" , and "Pola" , the last of which was completed to a slightly different design.
 The ships were a substantial improvement over the preceding "Trento"-class cruiser s, incorporating significantly heavier armor protection at the cost of the very high speed of the "Trento"s.
 They carried the same main battery of eight 203 mm guns and had a maximum speed of 32 kn .
 Among the best-protected heavy cruisers built by any navy in the 1930s, the heavy armor could only be acquired by violating the terms of the Washington Naval Treaty, which limited cruiser displacement to 10000 LT .
The "St. Louis"-class cruisers were a class of three cruisers that served in the United States Navy at the beginning of the 20th century.
 Authorized in fiscal year 1901 by an Act of Congress of 7 June 1900 as part of the naval buildup touched off by the Spanish-American War, the "St. Louis"-class cruiser initially began as an improved "Olympia" .
 However, during the design phase, decisions were made that increased the size of the vessel from to , including adding protection that resulted in the designation "semi-armored cruiser".
 This led to a larger power plant, and other decisions were made to try to increase speed and range, such as using smaller 6 in guns instead of 8 in guns, and adding coal capacity.
 The completed ship at 9,700 long tons was the same displacement as a full armored cruiser (such as the Royal Navy's "Monmouth" class , launched four years prior to the "St. Louis" class) without the same armor.
 One reference describes the class as "among the earliest well-documented examples of creeping growth in warship design".
HMS "Spartan" was an "Apollo"-class cruiser of the Royal Navy constructed in 1891.
 The design was a variant of the "Marathon"-class cruiser .
 The ships had quick firing guns which were effective as a broadside, but less so when attempting to fire fore or aft.
