The '''''Agile''-class''' minesweepers are a class of US-built ocean-going [[Minesweeper (ship)|minesweeper]]s. 58 ships were built for the [[United States Navy]], 35 ships were built for the allied [[North Atlantic Treaty Organization|NATO]] navies of [[Belgian Navy|Belgium]], [[French Navy|France]], [[Italian Navy|Italy]], the [[Royal Netherlands Navy|Netherlands]], [[Royal Norwegian Navy|Norway]] and [[Portuguese Navy|Portugal]]. 13 ships were later transferred to Belgium, [[Spanish Navy|Spain]], [[Republic of China Navy|Taiwan]], the [[Philippine Navy|Philippines]] and [[National Navy of Uruguay|Uruguay]].
 
There is some confusion on how to name this class.<ref>[http://www.navsource.orgnet/archives/11/02idx.htm NavSource minesweeper class]</ref> The class is often described as the [[Aggressive class minesweeper|''Aggressive''-class]], as {{USS|Aggressive|MSO-422}} was the first ship to be commissioned. Sometimes four ships are a ''Dash''-class subclass, although all ships are of the same design.<ref>Paul H. Silverstone: ''US Warships since 1945''. Allan Ltd., Shepperton, Surrey (UK) 1986, p. 127. {{ISBN|0711015988}}</ref>

==Modernization==
Although it was planned to modernize all U.S. Navy ship of this class, only 19 ships were modernized starting with Fiscal Year 1968. The modernization cost between 700,000 and $1,500,000 $ per ship and should enable them to operate for another ten years. The ships received new aluminum block Waukesha diesel engines and the superstructure was enlarged aft. The UQS-1 sonar was replaced with SQQ-14. Two PAP-104 cable-guided undersea tools were added. Also, two 40&nbsp;hp zodiacs were carried for the purpose of mooring the new sonar reflectors. Also, a team of [[Underwater Demolition Team|mine clearance divers]] was added. Additional space on the foc'sle was needed for installation of the SQQ-14 cabling so the 40mm Bofors bow gun was replaced with a mount for a twin 20&nbsp;mm Mk 68 gun.<ref>Terzibaschitsch, p. 609; http://www.allwoodships.com/MilitaryShips/MineWarfare/AM-421,Agile-Aggressive.htm {{Webarchive|url=https://web.archive.org/web/20150402142712/http://www.allwoodships.com/MilitaryShips/MineWarfare/AM-421,Agile-Aggressive.htm |date=2015-04-02 }}</ref>
 
On July 1st, 2025, the last Agile-class minesweeper, [[USS Implicit (AM-455)|ROCS ''Yung Yang'']] retired from Taiwan Navy service. <ref>{{cite web | title=海軍大岡、永陽艦除役 歷屆艦長不捨細數服役歷程 - 軍事 | date=July 2025 | url=https://www.chinatimes.com/realtimenews/20250701003269-260417?chdtv }}</ref><ref>{{cite web | title=大岡軍艦ATF-554除役最後降旗典禮及最後身影/永陽軍艦MSO-1306最後身影(謝謝林老師Roger Lin提供) | website=[[YouTube]] | date=July 2025 | url=https://www.youtube.com/watch?v=tW5rE2HyMCc }}</ref><ref>{{cite web | title=20250701-大岡(Atf-554)與永陽(Mso-1306)軍艦今天除役,感謝二艘軍艦捍衛國家,感謝木殼船上的鋼鐵人的保家衛國 | website=[[YouTube]] | date=July 2025 | url=https://www.youtube.com/watch?v=PBT5drSboL4&t=22s }}</ref>
