Alfredo Cappellini was an Italian monitor converted from the floating crane GA53 during World War I. She bombarded Austro-Hungarian positions during the Eleventh Battle of the Isonzo in 1917 before she was wrecked off Ancona on 16 November 1917. Development and descriptionAlfredo Cappellini was built when Cannone navali da 381/40 guns from the {{sclass-|Francesco Caracciolo|battleship|2}}s became available after their construction was suspended in 1916. Her guns were built by Ansaldo-Schneider and originally destined for the {{ship|Italian battleship|Francesco Morosini||2}}. Converted from the floating crane GA53, she displaced {{convert|1452|LT|MT}}, with a length between perpendiculars of {{convert|36|m|ftin|sp=us}}, a beam of {{convert|18|m|ftin|sp=us}} and a draft of {{convert|2.4|m|ftin|sp=us}}. The ship was powered by one {{convert|265|ihp|kW|lk=in|adj=on}} vertical double-expansion steam engine. On sea trials the ship reached a maximum speed of {{convert|3.76|kn|1|lk=in}}, but her maximum speed in regular service was about {{convert|3.5|kn}}.[1]Her hull and gun turret were unarmored, but she was protected by two anti-torpedo nets.[2] Her main guns could elevate 20° and her turret could traverse 30° to either side.[1] They fired an {{convert|884|kg|0|abbr=on}} armor-piercing shell at a muzzle velocity of {{convert|700|m/s|0|abbr=on}} to a range of {{convert|27300|m|0|abbr=on}} at maximum elevation.[3] ServiceAlfredo Cappellini was launched in 1915, even before the battleships were officially suspended, by the Orlando Shipyard, in Livorno, completed on 24 April 1917 and commissioned four days later. Her first action came during the Eleventh Battle of the Isonzo in August 1917. She, in company with the Italian monitor {{ship|Italian monitor|Faà di Bruno||2}} and the British monitors {{HMS|Earl of Peterborough||6}} and {{HMS|Sir Thomas Picton||6}}, bombarded Austrian positions with little noticeable effect.[4] She was wrecked on 16 November 1917 off Ancona.[1]References1. ^1 2 Trawick and Wiltering, p. 298 2. ^Gardiner and Gray, p. 287 3. ^{{cite web|url=http://www.navweaps.com/Weapons/WNIT_15-40_m1914.htm|title=Italian 381 mm/40 (15") Model 1914 |date=9 October 2006|accessdate=18 November 2009}} 4. ^{{cite book|last=Buxton|first=Ian|title=Big Gun Monitors: Design, Construction and Operations 1914–1945|publisher=Naval Institute Press|location=Annapolis, MD|year=2008|edition=2nd revised and expanded|page=71|isbn=978-1-59114-045-0}} Bibliography{{refbegin}}
