The interior of the P-3 Orion 'Cisne 31', a Spanish plane that tracked Soviet submarines

The Lockheed P-3 Orion has been the best maritime patrol aircraft that Spain has ever had in the entire history of its military aviation.

Spanish Air Force will receive 16 C295W MPA/MSA: this is how these aircraft are for maritime missions

On December 16, 2022, the farewell ceremony for the last P-3 Orion of the Spanish Air Force, the P.3M-08 (22-31), was held after 35 years of service in the Spanish Air Force, with which it flew a total of 11,000 hours. The first three Spanish P-3As (the P.3-1, P.3-2 and P.3-3) were delivered on July 25, 1973. These three aircraft had already logged many flight hours for the US Navy.

In January of this year we reviewed the history of these aircraft here, on the occasion of the publication of an interesting video by the Youtube channel Fly By Wire Aviation (I recommend you subscribe if you like aeronautical topics) about the P.3A-01 (ex P.3-1), with radio callsign "Cisne 31", preserved in the Cuatro Vientos Air Museum, in Madrid.

The "Cisne 31", like the other Spanish P-3 Orions, dedicated part of its missions to tracking Soviet submarines that sailed near Spanish waters during the Cold War years. Today, thanks again to the Fly By Wire Aviation channel, we can see what the interior of that aircraft is like, in which its crews, made up of up to 14 people, worked for so many hours until the P.3A-01 was retired from service in 2017:
