About: Harbour defence motor launch

An Entity of Type: ship, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

The harbour defence motor launch (HDML) was a 72 ft (22 m) long British-designed motor vessel used for harbour defence during World War II. Nearly 500 were built by numerous Allied countries during the war. The HDML was designed by W J Holt at the Admiralty in early 1939. During the war HDMLs were constructed, mainly by yacht builders, in the United Kingdom and a number of other Allied countries. In view of their later expanded combat roles in some Commonwealth navies some HDMLs were re-designated as "seaward defence motor launches" (SDML) or "seaward defence boats" (SDB).

  • Le Harbour Defence Motor Launch sono state una tipologia di unità costruite per la Royal Navy britannica durante la seconda guerra mondiale per proteggere le installazioni portuali e litoranee da incursioni nemiche. In totale vennero costruite 486 unità, spesso utilizzando piccoli cantieri navali privati viste le misure ridotte delle imbarcazioni. Il progetto, risalente al 1939, venne presentato all'Ammiragliato da W J Holt. (it)
  • Рейдовий сторожовий катер (англ. harbour defence motor launch, HDML) — невеликий британський патрульний катер, що застосовувався у Другій світовій війні. Ці катери були створені В. Дж. Холтом (W J Holt) в Адміралтействі на початку 1939. Впродовж війни було побудовано 464 рейдових сторожових катери, переважно будівниками яхт у Великій Британії та її домініонах, а також у США. Враховуючи розширення бойової ролі цих катерів у деяких флотах Співдружності націй вони були перекласифіковано на «морехідні моторні сторожові катери» (англ. «seaward defence motor launches» (SDML) або "морехідні сторожові катери (англ. — «seaward defence boats» (SDB).
