The Neptunes flown by the Coastal Command were all delivered in the overall sea blue paint scheme. Although initially delivered to No. 217 Squadron in 1952, WX497 was later operated by No. 236 Operational Conversion Unit (OCU). WX497 still wears the older style squadron markings; "C" denoting No. 236 OCU and "H", repeated on the nose, identifying the plane letter. This aircraft was sold for scrap in 1958.
In 1956, Coastal Command would change the Squadron markings replacing the large squadron letters with the actual squadron numbers. The aircraft letter would still be carried on the nose and in many cases, the tail. Initially delivered in 1953 with the longer Aero 9C nose turret, WX543 was one of the 27 aircraft which recieved the nose/MAD tail modifications by Scottish Aviation, and operated by No. 36 Squadron at Topcliffe. In 1958 this aircraft was returned to the USA and later delivered to the Força Aérea Brasileira as P-15 7000.
Towards the end of its service life with the RAF some Neptunes were repainted in overall Coastal Command Grey, although the impending withdrawal of the type precluded any wide spread adoption of the color
scheme. WX529 operated by No. 210 Squadron, was one of at least two
aircraft known to have worn this scheme. Returned to the USA in 1958, WX529 would also serve with the Força Aérea Brasileira as P-15 7010.
