BL 9.2-inch Mk IX – X Naval Gun
The BL 9.2-inch Mk IX and Mk X gunsMk IX = Mark 9, Mk X = Mark 10. Britain used Roman numerals to denote Marks (models) of ordnance until after World War II. Hence these were the ninth and tenth models of BL 9.2-inch gun. were British breech loading guns of 46.7 calibre, in service from 1899 to the 1950s as naval and coast defence guns. They had possibly the longest, most varied and successful service history of any British heavy ordnance. History The Mk IX/X guns succeeded the BL 9.2-inch Mk VIII naval gun and increased the bore length from 40 to 46.7 calibres, increasing the muzzle velocity from . The Mk IX was designed as a coast defence gun, with a three-motion breech. Only fourteen were built and the Mk X, introduced in 1900 and incorporating a single-motion breech and changed rifling, succeeded them. As coastal artillery, the Mk X remained in service in Britain until 1956, and in Portugal until 1998. A total of 284 of the Mark X version were built by Vickers, of whic ...

Radar
Radar is a detection system that uses radio waves to determine the distance ('' ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution. Th ...

Greek Cruiser Georgios Averof
''Georgios Averof'' ( el, Θ/Κ Γεώργιος Αβέρωφ) is a modified armored cruiser built in Italy for the Royal Hellenic Navy in the first decade of the 20th century. The ship served as the Greek flagship during most of the first half of the century. Although popularly known as a battleship () in Greek, she is in fact an armored cruiser (), the only ship of this type still in existence. The ship was initially ordered by the Italian Regia Marina, but budgetary constraints led Italy to offer it for sale to international customers. With the bequest of the wealthy benefactor George Averoff as down payment, Greece acquired the ship in 1909. Launched in 1910, ''Averof'' arrived in Greece in September 1911. The most modern warship in the Aegean at the time, she served as the flagship of admiral Pavlos Kountouriotis in the First Balkan War, and played a major role in the establishment of Greek predominance over the Ottoman Navy and the incorporation of many Aegean islands to ...

Elswick Ordnance Company
The Elswick Ordnance Company (sometimes referred to as Elswick Ordnance Works, but usually as "EOC") was a British armaments manufacturing company of the late 19th and early 20th century History Originally created in 1859 to separate William Armstrong's armaments business from his other business interests, to avoid a conflict of interest as Armstrong was then Engineer of Rifled Ordnance for the War Office and the company's main customer was the British Government. Armstrong held no financial interest in the company until 1864 when he left Government service, and Elswick Ordnance was re-united with the main Armstrong businesses to form Sir W.G. Armstrong & Company. EOC was then the armaments branch of W.G. Armstrong & Company and later of Armstrong Whitworth. EOC's main customer in its early years was the British Government, but the Government abandoned "Armstrong guns" in the mid-1860s due to dissatisfaction with Armstrong's breech mechanism, and instead built its own rifled ...

The ''King Edward VII''s were among the last pre-dreadnoughts built for the Royal Navy before the construction and launch of the revolutionary battleship HMS ''Dreadnought'' in 1906, which immediately rendered them obsolescent. The ships served with the Atlantic Fleet from 1905 to 1907, when they were transferred to the Channel Fleet, though this service lasted only until 1908–1909, when they were reassigned to the Home Fleet.

Cressy-class Cruiser
The ''Cressy''-class cruiser was a class of six armoured cruisers built for the Royal Navy around 1900. Their design’s incorporation of a pair of 9.2-inch guns and armoured sides served to address criticism directed against the previous — advances made possible by their 1,000 ton increase in displacement over their predecessors. The ships were notably stable, except for a susceptibility to pitching. Service Until 1908, the ships served in Home waters, the Mediterranean and the Far East. On the outbreak of the First World War ''Cressy'', ''Aboukir'', ''Hogue'', ''Bacchante'' and ''Euryalus'' formed the Seventh Cruiser Squadron. Due to the obsolescence of the ships and because they were crewed by inexperienced reservists the squadron was known as the " Live Bait Squadron". This epithet proved prophetic when ''Cressy'', ''Hogue'' and ''Aboukir'' were sunk in a single action on 22 September 1914 by the German submarine ''U-9'' near the Dutch coast.
