The ''Audacious''-class battleships were designed by Sir Edward Reed at the request of the Board of Admiralty to serve as second-class battleships on distant foreign stations. ==Background and design== The principal motivation driving the Admiralty was the French policy, already well advanced, of dispatching their own small ironclads to these same distant stations. was under construction, and had been authorised. Both of these were turret-armed ships, and the press agitated for a turret-mounted armament in these newly ordered ships. The Admiralty, however, decided that as there had been built a long succession of successful broadside ironclads, and no turret-armed ships had been produced other than some coast-defence ships of low displacement and limited range, it would be better to await the assessment of ''Monarch'' and ''Captain'' before departing from the broadside principle. As the ships were intended for service in waters far distant from Britain, and given the limited efficiency of the steam engines of the period, it was necessary to equip them with a full sailing rig. Reed never wavered from his belief that in a fully rigged ship armament carried in a central broadside battery was the superior method, being unobstructed by masts and rigging. Both the designer and the Admiralty were therefore in total agreement that these ships should not be armed with turret-mounted artillery. The rig was later converted to a barque-rig, which required fewer hands to manage.〔 The ships were designed following the lines of , by then, more than five years old. Reed found that, on the dimensions of the older ship, the armament, armour and machinery would all be insufficient for the stated requirements, and asked for an increase in tonnage, which was reluctantly granted by the Board. Although four ships were required, initially only two, and were laid down. The Admiralty, following a commitment made to Parliament by the First Lord of the Admiralty, put the other two ships out to tender. Submissions of various designs were received: a broadside and turret ship from Mare & Company, a broadside ship from Palmers, a different broadside ship from Thames Ironworks, and turret ships from Napiers, Samudas and Lairds Co & Sons. All were determined to be in some way inadequate, and ultimately the third and fourth ships were built, with some delay, to the Admiralty design. This class was the first homogeneous class of battleships to be launched since the , and the last until the . 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Audacious-class ironclad」の詳細全文を読む スポンサード リンク
