Lockheed developed the "Quiet Star" ultra quiet observation aircraft for the US Army to track night troop and supply movements in Vietnam. 69-18005 was deployed there from 1970-72. Sold to the Special School District of St Louis County, Missouri in 1973, it was acquired by Harold and Vic Hanson of Seattle and rebuilt to flying status, registered N33YQ as a Lockheed-Hansen YO-3A with the FAA. The fairly unique aircraft was sold again in 1987, fully restored and donated to the Museum of Flight in 2014.
With the Snowbirds from at least 1988 through 1992, 114023 was later transferred to Canadian Forces School of Aerospace Technology and Engineering at CFB Borden, Ont. Classified as Category B instructional aid on 28 June 2000, it was marked 936B.
The electronic countermeasures version of the Intruder was originally developed for the Marines to replace their Douglas Skyknights. This Vietnam War veteran was delivered to Marine Composite Reconnaissance Squadron VMCJ-2 on April 23, 1969. After disestablishment of VMCJ-2 , the aircraft transferred to Navy Tactical Electronic Warfare Squadron VAQ-309 and flew until that unit's disestablishment in 1994. Broken up sometime after retirement, the nose section ended up with the Yankee Air Museum at Willow Run Airport in Michigan.
