It was the last type of gun to be fitted to British submarines, finally being retired in 1974. Development and serviceDevelopment of the Mark XXIII began in 1942, as a lighter replacement for the QF 4-inch gun Mark XXII, which was based on a gun introduced in 1911. It was too late to see service in World War II, but was fitted to Amphion-class submarines that completed after October 1945.[2] It was also fitted to some T-class submarines.[1] Between 1955 and the early 1960s, the Amphion-class boats were modernised with new streamlined conning towers and casings. This work included the removal of the deck gun, although the underlying supports for the gun mountings were retained in case they were required. This facility was put to use during the British involvement in the Indonesia–Malaysia confrontation from 1962 to 1966, when the flotilla of Amphion-class submarines which were deployed in the conflict were again fitted with Mark XXIII guns. These were used to counter blockade-running Indonesian junks and other small vessels.[3] HMS Andrew retained her gun into the 1970s; the last firing was on 2 December 1974.[1] Surviving examplesHMS Andrew's Mark XXIII gun is preserved at the Royal Navy Submarine Museum, Gosport.[4] References1. ^1 2 {{cite web |url=http://www.navweaps.com/Weapons/WNBR_4-33_mk23.htm |title=Britain - 4"/33 (10.2 cm) QF Mark XXIII |last1= |first1= |last2= |first2= |date=22 October 2008 |website=www.navweaps.com |publisher=Tony DiGiulian |accessdate=21 March 2014}} 2. ^{{cite web |url=http://www.feralchicken.co.uk/lambert-plans/encom/naval_weapons_comp.htm |title=Naval Weapons, Equipment, Fittings & Boats. |last1=Lambert |first1=John |last2= |first2= |date= |website=www.feralchicken.co.uk/lambert-plans/ |publisher=John Lambert Plans |accessdate=21 March 2014}} 3. ^Akermann, Paul (2002), [https://books.google.com/books?id=boO7WGL21EQC&pg=PA427&lpg=PA427&dq=Amphion+class+submarine+deck+gun&source=bl&ots=LRGqpa4xn9&sig=Ctqg3ejDPZLaR7rKTO-e3Q8_orY&hl=en&sa=X&ei=poEsU_iNHMiY0AWxqYAI&ved=0CC0Q6AEwADgK#v=onepage&q=Amphion%20class%20submarine%20deck%20gun&f=false Encyclopedia of British Submarines 1901-1955], Periscope Publishing Limited, {{ISBN|1-904381-05-7}} (pp. 426-427) 4. ^{{cite web |url=http://www.navy.mil/navydata/cno/n87/usw/issue_19/royal_navy2.htm |title=Royal Navy Submarine Museum |last1=Whitman |first1=Edward C |last2= |first2= |date=Summer 2003 |website=www.navy.mil |publisher=Undersea Warfare - The Official Magazine of the U.S. Submarine Force |accessdate=21 March 2014}} External links
