Lacking the expensive, heavy and sensitive anti-submarine warfare as well as the anti-surface warfare fittings of the CP-140 Aurora, the Arcturus was more fuel efficient and was used for crew training duties (such as ''touch-and-go'' landing practice), general maritime surface reconnaissance (detecting drug operations, smuggling of illegal immigrants, fisheries protection patrols, pollution monitoring, etc.), [[search-and-rescue]] assistance and Arctic sovereignty patrols.  The Arcturus did possess a superior AN/APS-507 surface search radar, incorporating modern functions such as [[track-while-scan]] that the Aurora's AN/APS-506 radar lacks but the Arcturus did not have an integrated mission computer, or mission systems. It did, however, maintain the same military communications suite as the CP-140 Aurora.{{Citation needed|date=March 2007}}

All three aircraft were based at 14 Wing. Upon retirement from flying operations, one was used for technician training with [[No. 404 Squadron RCAF|404 Long Range Patrol and Training Squadron]] on base [[CFB Greenwood]], [[Nova Scotia]], before being moved to the [[Greenwood Military Aviation Museum]] on base.  The last two of the CP-140As were retired in 2011 when they were delivered to the [[309th Aerospace Maintenance and Regeneration Group|Aerospace Maintenance and Regeneration Group (AMARG)]] in [[Tucson]], [[Arizona]].<ref>Nicholson, Pete (Sergeant).
