China and Taiwan are also claimants of the reef. Like Spratly Island, Ladd Reef lies to the west of the Philippines-defined "Kalayaan Islands" claim area.[1] NamesThe English name Ladd Reef was coined by Richard Spratly in late March 1843, after Captain Ladd of the ship Austen, who seemed to be the first to have seen the reef.[2] The Chinese name Rìjī Jiāo was coined in 1947 to replace the 1935 name Lādé Jiāo (拉德礁),[3] which was transliterated from the English name Ladd. GeographyLadd Reef lies west of Dangerous Ground in the western half of the Spratly Islands, to the south of Coronation Bank, southwest of West London Reef (West Reef) and {{convert|15|nmi}} west of Spratly Island.[4] This coral reef lies on a northeast-southwest axis, {{convert|3|nmi}} in length, {{convert|1|nmi}} in width, and spans over an area of {{convert|9.9|km2|ha acre sqmi}}. It is entirely submerged during high tide, but there are some stones jutting out of the sea during low tide.[5] StructuresThe reef is uninhabited but contains a Vietnamese lighthouse (built in 1994)[6] with the inscription Hải đăng đá Lát[7] (literally "Ladd Reef Lighthouse"). The lower portion of the lighthouse consists of quarters for a handful of Vietnamese soldiers and the lighthouse keeper. Other informationIn 1945, towards the end of the Second World War, a Dutch submarine (HNLMS O-19) ran aground on Ladd Reef.[8] References1. ^{{cite web |url=http://www.gov.ph/1978/06/11/presidential-decree-no-1596-s-1978/ |year=1978 |title=Presidential Decree No. 1596 (Philippines) |publisher=The Official Gazette of the Republic of the Philippines |accessdate=2014-07-15}} {{Spratly Islands topics}}{{asia-geo-stub}}2. ^{{cite book|author1=Hancox, David |author2=Prescott, Victor |title=A Geographical Description of the Spratly Islands and an Account of Hydrographic Surveys amongst Those Islands |year=1995 |publisher=University of Durham, International Boundaries Research Unit|url=https://www.dur.ac.uk/ibru/publications/view/?id=229 |series=Maritime Briefings |volume=1 |isbn=978-1897643181 |page=[https://books.google.com/books?id=7Qu9fi-luTYC&pg=PA15&lpg=PA14&focus=viewport&dq=%22ladd+reef%22+spratly+%22atoll%22&hl=vi 15]}} 3. ^{{cite web |url=http://www.hnszw.org.cn/data/news/2009/06/43675/ |script-title=zh:南海诸岛中外地名对照表 |publisher=海南史志网 |date=2009-06-15 |accessdate=2014-07-15 |language=Chinese}} (Contains a list of maritime features in the South China Sea, with their English names, and their Chinese names in 1935, 1947 and 1983.) 4. ^{{cite news |last1=Sta Ana |first1=D.J. |title=Vietnam also has garrisons in PH zone of Spratlys |url=http://www.interaksyon.com/article/4119/vietnam-also-has-garrisons-in-ph-zone-of-spratlys |accessdate=6 June 2014 |publisher=Interaksyon |date=25 May 2011}} 5. ^{{cite book |title=Những điều cần biết về hai quần đảo Hoàng Sa, Trường Sa và khu vực thềm lục địa phía nam [What you need to know about Paracel Islands, Spratly Islands and southern continental shelf] |year=2011 |publisher=Political Department, Naval Command (Vietnam)|language=Vietnamese}} 6. ^{{cite web |title= Lighthouses of the Spratly Islands |date= 15 November 2013 |author= Russ Rowlett |publisher= University of North Carolina at Chapel Hill |accessdate= 6 June 2014 |url= http://www.unc.edu/~rowlett/lighthouse/spr.htm }} 7. ^{{cite web |title=Photo of Lighthouse on Ladd reef |url=http://www.timawa.net/forum/index.php?topic=32563.15 |website=timawa.net/ |publisher=Timawa - Forum |accessdate=6 June 2014}} 8. ^{{cite web |last1=Spruijt |first1=Siem |title=The Ladd reef Incident |url= http://www.dutchsubmarines.com/specials/special_fatalpatrolo19.htm |website=dutchsubmarines.com |publisher=Dutch Submarines |accessdate=6 June 2014}} 1 : Reefs of the Spratly Islands |
