The aircraft is flown by a crew of ten on missions up to 14 hours long. The flight deck accommodates the pilot, the co-pilot and the flight engineer. The main cabin is configured as a mission operations room for the tactical coordinator, the navigator and communications operator, two operators for the acoustic sensor suite, the electromagnetic sensors systems operator (responsible for the operation of the radar, electronic support measures, infrared detection system and magnetic anomaly detectors), the ordnance crew member and the flight technician. Circular protruding windows in the main cabin give the crew a 180° view. The P-3C's anti-submarine warfare systems include the AN/ARR-78(V) sonobuoy receiving system supplied by Hazeltine Corporation of New York, the AN/ARR-72 sonobuoy receiver supplied by Fighting Electronics Inc of New York for the operation and management of buoys, two AQA-7 directional acoustic frequency analysis and recording sonobuoy indicators, and a AQH-4 (V) sonar tape recorder. The sensor suite also includes an ASQ-81 magnetic anomaly detector and an ASA-65 magnetic compensator. Sonobuoys are launched from within the main cabin and from the external hardpoints. The airborne electronic surveillance receiver, ALQ-78(V) is carried on a pylon under the wing fairing. The system is supplied by Lockheed Martin based in New York and has also been manufactured under licence by Mitsubishi in Japan. The bomb bay is in the underside of the fuselage forward of the wing. It is capable of carrying a 2,000lb mine such as the mk25, mk39, mk55 or mk56. Alternative ordnance includes 1,000lb mines, depth bombs, torpedoes, or nuclear depth bombs. The underwing pylons can carry 2,000lb mines, torpedoes, rockets, rocket pods and 500lb mines. The US Navy P-3C aircraft are equipped to carry the Harpoon AGM-84 anti-ship and stand-off land attack missile. During the late 1990s the US Navy P-3C Orions armed with the Harpoon were deployed in Yugoslavia.
