Editing Lockheed S-3 Viking (section)

===Potential revival and proposals===
In October 2013, the [[Republic of Korea Navy]] expressed its interest in acquiring up to 18 ex-USN S-3s to augment their fleet of 16 Lockheed P-3 Orion aircraft.<ref>Sung-Ki, Jung [http://archive.defensenews.com/article/20131026/DEFREG03/310260005/S-Korea-Envisions-Light-Aircraft-Carrier "S.

Retrieved: 13 March 2015.</ref> In August 2015, a military program review group approved a proposal to incorporate 12 mothballed S-3s to perform ASW duties; the Viking plan was sent onto the [[Defense Acquisition Program Administration]] for further assessment before final approval decision by the national defense system committee. Although the planes are relatively old, being in storage has supposedly kept them serviceable, and using them is an affordable means of fulfilling short-range airborne ASW capabilities that were vacated by the retirement of the S-2 Tracker.<ref>{{cite web |url = http://english.yonhapnews.co.kr/national/2015/09/06/0301000000AEN20150906002600320.html |title = S.

During April 2014, Lockheed Martin announced that they would offer refurbished and remanufactured S-3s, dubbed the ''C-3'', as a replacement for the Northrop [[Grumman C-2A Greyhound]] for [[carrier onboard delivery]]. The requirement for 35 aircraft would be met from the 91 S-3s currently in storage.<ref>{{cite web |last = Cavas |first = Christopher P. |url = http://www.defensenews.com/article/20140409/DEFREG02/304090028/ |title = Lockheed revives an old idea for new carrier cargo plane |publisher = Defense News |date = 9 April 2014 |archive-url=https://archive.today/20150209193642/http://www.defensenews.com/article/20140409/DEFREG02/304090028/ |archive-date=9 February 2015 |url-status=dead}}</ref> In February 2015, the Navy announced that the [[Bell Boeing V-22 Osprey]] had been selected to replace the C-2 for the COD mission.<ref>{{cite web |last = Kreisher |first = Otto |url = http://breakingdefense.com/2015/02/navy-2016-budget-funds-v-22-cod-buy-carrier-refuel/ |title = Navy 2016 budget funds V-22 COD buy, carrier refuel |publisher = Breaking Defense |date = 2 February 2015}}</ref><ref>{{Cite web |url = http://news.usni.org/2015/01/13/navy-selects-bell-boeing-osprey-next-carrier-delivery-aircraft |title = Navy and Marines Sign MOU for Bell-Boeing Osprey to be Next Carrier Delivery Aircraft |publisher = News.USNI.org |date = 13 January 2015}} {{Cite web |url=http://news.usni.org/2015/01/13/navy-selects-bell-boeing-osprey-next-carrier-delivery-aircraft |title=Updated: Navy and Marines Sign MOU for Bell-Boeing Osprey to be Next Carrier Delivery Aircraft |date=13 January 2015 |access-date=23 May 2022 |archive-date=18 January 2015 |archive-url=https://web.archive.org/web/20150118201328/http://news.usni.org/2015/01/13/navy-selects-bell-boeing-osprey-next-carrier-delivery-aircraft |url-status=live}}</ref> A SV-22 was a proposed [[anti-submarine warfare]] variant the U.S. Navy studied in the 1980s to replace S-3 Viking and late model [[Kaman SH-2 Seasprite|SH-2 Seasprite]] ASW helicopters.<ref name="Norton_p28_48">Norton 2004, pp. 28–30, 35, 48.</ref>
