'''USNS ''Impeccable'' (T-AGOS-23)''' is an [[Impeccable
==Construction==
''Impeccable'' was built by [[American Shipbuilding]], [[Tampa, Florida]]. The contract was awarded on 28 March 1991. The ship's keel was laid down on 15 March 1992, but the Tampa shipyards went bankrupt by November 1993.<ref>{{cite news |url=https://
==Design==
The ship is a designated [[T-AGOS]] vessel built to tow a [[Surveillance Towed Array Sensor System]]. The ship's [[catamaran]]-type [[small waterplane area twin hull]] (SWATH) design prevents the vessel from rolling in heavy seas and gives additional deck space for storing the acoustic equipment.<ref>
==Mission==
The mission of ''Impeccable'' is to directly support the Navy by using [[SURTASS]] passive and active low frequency [[sonar]] arrays to detect and track undersea threats.
==Operational history==
Line 95 ⟶ 96:
===Low Frequency Active Sonar===
{{Main|Surveillance Towed Array Sensor System}}
*The SURTASS [[Low Frequency Active Sonar]] system, onboard ''Impeccable'', commenced sea trials in late February 2004. During the spring and summer of 2004, ''Impeccable'' conducted five training missions in the Philippine Sea and the northwest Pacific Ocean
* Total operational days on board
:(15 August 2003 to 15 August 2004) 26.2 days with 63.0 hours of transmissions
:(15 August 2004 to 15 August 2005)
:(15 August 2005 to 15 August 2006) 22.5 days with 39.4 hours of transmissions.<ref>{{cite web |url=http://www.nmfs.noaa.gov/pr/pdfs/permits/surtass_lfa_final_report.pdf |title=Final Comprehensive Report for the Operation of the Surveillance Towed Array Sensor System Low Frequency Active (SURTASS
*The ship had five years of active and passive operations in the Western Pacific before the incident in the South China Sea.

The United States lodged formal protests following the incident, stating that under international law, the U.S. military can conduct activities "in waters beyond the territorial sea of another state without prior notification or consent" including in an [[exclusive economic zone]] of another country. "The unprofessional maneuvers by Chinese vessels violated the requirement under international law to operate with due regard for the rights and safety of other lawful users of the ocean."<ref name="WP0309"/><ref name="REUTERS">
On 12 March 2009, U.S. President [[Barack Obama]] gave the go-ahead to send the [[guided missile destroyer]]
[[Hans M. Kristensen]] of the [[Federation of American Scientists]] has suggested that the incident may be related to the classified [[Type 093 submarine]] that the Chinese navy had recently deployed in the area.<ref>
====Views on the legality of US and Chinese actions during these incidents====
[[File:USNS Impeccable T-AGOS-23 port forward view.jpg|thumb|''Impeccable'' in 2009]]
The United States maintains that the Convention, which it has signed, but not yet ratified, authorizes activities such as those undertaken by ''Impeccable''.<ref name="China hits out at US on navy row">

For example, Raul Pedrozo, writing in the ''Chinese Journal of International Law'', concludes that "all nations may legitimately engage in military activities in foreign exclusive economic zones, without prior notice to, or consent of, the coastal State concerned."<ref>{{cite web|url=http://www.mcclatchydc.com/251/story/63656.html |title=Archived copy |accessdate=2009-03-11 |deadurl=yes |archiveurl=https://web.archive.org/web/20090313045527/http://www.mcclatchydc.com/251/story/63656.html |archivedate=13 March 2009 |df= }}</ref><ref>http://papers.ssrn.com/sol3/papers.cfm?abstract_id=1565306</ref> On the contrary, Chinese officials assert that the operations are illegal. Rear Admiral [[Wang Dengping]], political commissar of the Armament Department of the [[Chinese Navy]], condemned the ''Impeccable's'' activities, stating that "Innocent passage by naval vessels from other countries in the [[Territorial waters]] in the [[Special Economic Zone]] is acceptable, but not allowed otherwise"<ref>[http://news.xinhuanet.com/english/2009-03/10/content_10985038.htm], [[Xinhua]], 10 March 2009</ref> under the Convention. Chinese actions were further defended by Professor Ji Guoxing of [[Shanghai Jiao Tong University]] who, writing in ''China Security'', maintained that under the Convention, navigation rights in coastal countries' exclusive economic zones are "subject to the resource-related and environment-related laws and regulations of the coastal state," and China could exclude the ''Impeccable'' on this basis. Ji further asserted that the Convention's prohibition against gathering military intelligence in another country's territorial waters should be interpreted to also prohibit intelligence gathering in coastal countries' exclusive economic zones.<ref>{{cite web|url=http://www.chinasecurity.us/pdfs/jiguoxing.pdf |title=Archived copy |accessdate=2011-09-14 |deadurl=yes |archiveurl=https://web.archive.org/web/20120327211055/http://www.chinasecurity.us/pdfs/jiguoxing.pdf |archivedate=27 March 2012 |df= }}</ref>
==2015 rescue at sea==
On July 19, 2015 while en route for a scheduled port visit to [[Subic Bay]], USNS ''Impeccable'' (T-AGOS 23) rescued 11 fishermen. ''Impeccable'' sailors spotted personnel on a partially submerged ship and noted debris in the water. "They [''Impeccable'' crew] initially spotted only eight people on the partially submerged vessel," said Lt. Cory Hilgart, the theater anti-submarine watch officer at Commander, Task Force 74. "They then realized that it was actually 11 and made the call to commence the rescue effort."
