Editing Lockheed P-3 Orion (section)

===In Vietnam===
{{Main|Operation Market Time}}

Beginning in 1964, forward deployed P-3s began flying various missions under [[Operation Market Time]] from bases in the Philippines and Vietnam. The primary focus of these coastal patrols was to stem the supply of materials to the [[Viet Cong]] by sea, although several of these missions also became overland "feet dry" sorties. During one such mission, a small caliber artillery shell passed through a P-3 without rendering it mission incapable. The only confirmed combat loss of a P-3 also occurred during Operation Market Time.<ref name="vpnavy.org">[http://www.vpnavy.org/vp26mem.html "VP-26 Memorial: VP-26 Crew – {{sic|In Memo|rium|hide=y|expected=In Memoriam}} – VP-26 Crew."] {{Webarchive|url=https://web.archive.org/web/20070510030438/http://www.vpnavy.org/vp26mem.html |date=10 May 2007 }} ''vpnavy.org.''

In April 1968, a U.S. Navy P-3B of [[VP-26]] was downed by anti-aircraft fire in the Gulf of Thailand with the loss of the entire crew. Two months earlier in February 1968, another one of VP-26's P-3Bs was operating in the same vicinity when it crashed with the loss of the entire crew. Originally attributed to a low altitude mishap, later conjecture is that this aircraft may have also fallen victim to anti-aircraft artillery (AAA) fire from the same source as the April incident.<ref name="vpnavy.org"/>
