Lockheed P-3 Orion

A Brazilian Air Force P-3AM Orion

Aircraft Overview

The Lockheed P-3 Orion is a maritime patrol aircraft designed by the Lockheed Corporation (later Lockheed Martin). It first flew in November 1959 and entered into service 3 years later in August 1962, thus meaning that in 2012 the aircraft was one of few to be in service for the US for over 50 years, along with the likes of the B-52 Stratofortress, KC-135 Stratotanker, C-130 Hercules and, most recently, the C-5 Galaxy (C-5A Galaxy thread) (C-5M Super Galaxy thread).

The aircraft is basically a military version of the L-188 Electra, featuring a redesigned nose, a slightly shortened fuselage and, most notably, a big “stinger” (a Magnetic Anomaly Detector (MAD), which easily detects the submarines due to their interference on Earth’s magnetic field) at the aft fuselage. The “stinger” is made of fiberglass due to the MAD’s sensivity and needs to be far away from the metal fuselage and the electronic warfare systems, however the aircraft needs to be close to the submarine at a very low altitude due to the MAD’s short range, meaning it’s primary use is to pinpoint the location of the submarine immediately before a torpedo launch or depth bomb attack.

Definitely not a priority for the development team (since there are not submarines in IF at least as far as we know, maybe there are and we never knew because no aircraft could detect them) however it’s a very nice patrol aircraft, seems fun to fly and would be a great addition to the sadly small military fleet in Infinite Flight.

You got my vote! Looks like the hurricane hunter plane!


I would 1000% love to see the P-3 Orion in Infinite flight!


Got my vote for sure .

My dad got to fly on these in the navy!


Not only does it look like one, I’m pretty sure it is one! I mean, the Hurricane hunter ones are probably pretty different, but same airframe!
