Design The design for the class had a displacement of 270 tonnes. The ships had a length of , a beam of , and a draft of . The vessels were capable of , being powered by two General Motors (Cleveland) 8-268A, 2-cycle diesel engines which drove two shafts. The ships had a complement of 32. Their armament comprised one single 3-inch/50 caliber gun mount, two 20 mm anti-aircraft guns and two depth charge projectors. ''YMS-1''-class ships were relatively small compared to larger contemporary US Navy ships. This led to a view by some sailors that the YMS-designated ships were cramped and particularly unsteady. These conditions were described (and surely exaggerated) by one auth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-air Warfare
Anti-aircraft warfare, counter-air or air defence forces is the battlespace response to aerial warfare, defined by NATO as "all measures designed to nullify or reduce the effectiveness of hostile air action".AAP-6 It includes Surface-to-air missile, surface based, subsurface (Submarine#Armament, submarine launched), and air-based weapon systems, associated sensor systems, command and control arrangements, and passive measures (e.g. barrage balloons). It may be used to protect naval, ground, and air forces in any location. However, for most countries, the main effort has tended to be homeland defence. NATO refers to airborne air defence as counter-air and naval air defence as anti-aircraft warfare. Missile defense, Missile defence is an extension of air defence, as are initiatives to adapt air defence to the task of intercepting any projectile in flight. In some countries, such as Britain and Germany during the World War II, Second World War, the Soviet Union, and modern NATO a ...

85 Mm Air Defense Gun M1939 (52-K)
The 85 mm air defense gun M1939 (52-K) (russian: 85-мм зенитная пушка обр. 1939 г. (52-К)) was an Soviet anti-aircraft gun, developed under guidance of leading Soviet designers M. N. Loginov and G. D. Dorokhin. This gun was successfully used throughout the German-Soviet War against level bombers and other high- and medium-altitude targets. In emergencies they were utilized as powerful anti-tank weapons. The barrel of the 52-K was the basis for the family of 85-mm Soviet tank guns. After the war some 52-Ks were refitted for peaceful purposes as anti-avalanche guns in mountainous terrain. Virtually every country behind the Iron Curtain received this gun after World War II for their air defense. In the Soviet Union itself, these guns were largely superseded by the 100 and 130 mm guns. Description Adopted in 1939, the 85-mm M1939, like its German counterpart the 88-mm Flak 18/36/37, was meant for air defense. Like many anti-aircraft (AA) guns of the er ...
