The EOC 4-inch 50 caliber was a British naval gun designed by the Elswick Ordnance Company for export customers in the years before World War I that armed warships of the Republic of China and the Greek Navy. These ships served in both World War I and later World War II.
History[]
The EOC 4-inch 50 caliber began life as a design produced by the parent company of Elswick, Armstrong Whitworth for export customers called the Pattern P. These guns did not serve aboard ships of the Royal Navy.[1]
Construction[]
The EOC 4-inch 50 caliber was constructed of an A tube and wire wound with a protective outer jacket. It also had a horizontal sliding-wedge breech and fired fixed quick fire ammunition.[1]

EOC 4-inch 50 caliber guns armed coastal defense ships, destroyers and protected cruisers.
Coastal defense ships:
- Yongfeng class - Two of the four ships of this class Yongjian and Yongji were armed with a single bow mounted EOC 4-inch gun. While Yongfeng and Yongxiang were similar in configuration they carried a single bow mounted Krupp 10.5 cm SK L/40 gun instead.[2][3]
Destroyers:
- Aetos class - The four ships of this class had a primary armament of four EOC 4-inch guns. One was bow mounted, one was amidships and two were at the stern.[4][5]
Protected cruisers:
- Chao Ho class - Two ships of this class Chao Ho and Ying Swei had a secondary armament of four shielded EOC 4-inch guns on sponsons amidships. The third ship of the class named Elli was sold to Greece before completion and had a different armament scheme.[6][7][8]
