The P-3C Orion, developed by Lockheed Martin Aeronautical Systems Company, a land-based, long-range, anti-submarine warfare (ASW) patrol aircraft. For anti-submarine misson, advanced submarine detection sensors, such as directional frequency and ranging (DIFAR) sonobuoys and magnetic anomaly detection (MAD) equipment are equiped in P-3C.

February 1959, the US Navy was looking for a replacement for the aging P2V Neptune. The P3V Orion, based on Lockheed's successful L188 Electra airliner, entered the inventory in July 1962. After that, it remains the Navy's sole land-based antisubmarine warfare aircraft for 40 years. During designation change, it was renamed from P3V to P-3, and have three major models: P-3A(photo on the top), P-3B, and P-3C. the latter is now the only one in service. The last Navy P-3 came off the production line in April 1990. The unit cost is $36 million. The P-3 made its first flight in November 1959, The P-3A became operational in August 1962 and P-3C in August 1969, view two photoes down here.

The avionics system is integrated by a general purpose digital computer, which settle all of the tactical displays, monitors and automatically launches ordnance and provides flight information. The system coordinates navigation info and accepts sensor data inputs for tactical display and storage. The P-3C`s armament include a mixed payload of weapons internally and on wing pylons.

The P-3C`s armament include AGM-84 Harpoon cruise missile, AGM-65 Maverick air-to-ground missiles, MK-46 torpedoes, depth charges, sonobuoys. And mines up to around 20,000 pounds (9 tons) internal and external loads. The aircraft is powered by four Allison T-56-A-14 turboprop engines, 4,600 shaft horsepower each.

The P-3C Update Ⅲ is a multi mission aircraft capable of either operating alone, or supporting many different customers including the carrier battle group and amphibious readiness group. Its missions include anti-surface warfare, and-submarine warfare, mining, reconnaissance and surveillance. The aircraft can carry a variety of weapons such as the Harpoon anti-surface missile, the MK-50 torpedo and the MK-60 mine. Each 11-person crew includes both officer and enlisted personnel.

The P-3C Update III Anti-SUrface Warfare Improvement Program [ASUWIP] Aircraft will provide improvements in Command, Control, Communications, and Intelligence; surveillance and OTH-T capabilities; and survivability, to include the Maverick Missile System. Delivery of the P-3C Update III Anti-Surface Warfare (ASUW) Improvement Program (AIP) Aircraft to the fleet began 29 April 1998 and is scheduled to be complete at the close of FY00. The P-3C Update III AIP will be accomplished through the retrofit of P-3C Update III Aircraft that have the CP-2044 Digital Data Computer and AN/ALR-66B(V)3 Electronic Support Measures Set installed. Transition to the P-3C Update III AIP Aircraft began in April 1998. Since, as currently envisioned, squadrons will initially operate both the P-3C Update III and P-3C Update III AIP Aircraft, aircrew and maintenance personnel will require training for both aircraft configurations. Training track lengths will increase with the inclusion of the P-3C Update III AIP Aircraft information into existing training tracks. The P-3C Update III AIP Aircraft equipment includes:

The IR Maverick Missile is an infrared-guided, rocket-propelled, air-to-ground missile for use against targets requiring considerable warhead penetration prior to detonation. The missile is capable of two pre-flight selectable modes of target tracking. The armor or land track mode is optimized for tracking land-based targets such as tanks or fortified emplacements. The ship track mode is optimized for tracking seaborne targets. The missile is capable of launch-and-leave operation. After launch, automatic missile guidance is provided by an imaging infrared energy sensing and homing device.

The AN/AAS-36A Infrared Detecting Set [IRDS] provides passive imaging of infrared wavelength radiation to visible light emanating from the terrain along the aircraft flight path for stand-off detection, tracking, and classification capability. The IRDS update will primarily consist of an improved A-focal lens.

The AN/AVX-1 Electro-Optical Sensor System [EOSS] is an airborne stabilized electro-optical system that provides video for surveillance and reconnaissance missions. The AN/AVX-1 EOSS has the capability to detect and monitor objects during the day from exceptionally clear to medium hazes, dawn and dusk, and during the night from a full moon to starlight illumination.

The AN/APS-137B(V)5 Radar is capable of multimode operation to provide periscope and small target detection, navigation, weather avoidance, long range surface search and Synthetic Aperture Radar (SAR) and ISAR imaging modes. SAR provides detection, identification, and classification capability of stationary targets. ISAR provides detection, classification, and tracking capability against surface and surfaced submarine targets. The AN/APS-137B(V)5 ISAR provides range, bearing, and positional data on all selected targets, and provides medium or high resolution images for display and recording.

The EP-2060 Pulse Analyzer works in conjunction with the AN/ALR-66C(V)3 to detect, direction find, quantify, process, and display electromagnetic signals emitted by land, ship, and airborne radar systems.

Three Color High Resolution Display [CHRD] general purpose, dual channel, closed circuit units provide the operator with improved Operator-Machine-Interface and 1024 X 1280 pixel landscape orientation, improved response time to operator commands, and an increase of 300 percent in the video refresh rate to minimize display flicker. Five types of data may be displayed on the CHRD: cursors, cues, tableau, alerts, and raw video.

The Pilot Color High Resolution Display [PCHRD] provides the ability to display complex tactical and sensor information to the pilot station.

The Over-the-Horizon Airborne Sensor Information System [OASIS] III data is received and prepared for transmission via the OASIS III Tactical Data Processor (TDP). OASIS III processes and correlates all data provided via MATT and Mini-DAMA. The OASIS III TDP provides an Officer in Tactical Command Information Exchange System (OTCIXS) message link, coupled with GPS-aided targeting using the AN/APS-137B(V)5 Radar.

The OZ-72(V) Multi-Mission Advanced Tactical Terminal [MATT] system will provide Tactical Receive Equipment (TRE) capability to receive and decrypt three simultaneous channels of Tactical Data Information Exchange Subsystem (TADIXS-B), Tactical Related Applications (TRAP), and Tactical Information Broadcast Service (TIBS) information. The system will route the received broadcast data to the OASIS III for further processing.

The AN/USC-42(V)3 Miniaturized Demand Assigned Multiple Access [Mini-DAMA] will provide for secure voice communications. Mini-DAMA provides for the transmission, reception, and decryption of OTCIXS data and the subsequent routing of that data to the OASIS III TDP.

The AN/AAR-47 Missile Warning System [MWS] is a passive electro-optical system designed to detect surface-to-air and air-to-air missiles. Upon detection of an incoming missile, the MWS will report the impending threat to the Countermeasures Dispensing System (CMDS).

The AN/ALE-47 Countermeasures Dispensing System [CMDS] will be used for dispensing flares, chaff, non-programmable expendable jammers, and programmable jammers.

The AN/ALR-66C(V)3 Electronic Support Measures Set provides all the same features as an AN/ALR-66B(V)3 ESM Set. However, the ALR-66C(V)3 Set incorporates the AS-105 spinning DF antenna and the Operational Flight Program is modified to accommodate this configuration difference. Also included is the EP-2060 Pulse Analyzer, an upgrade to the ULQ-16.
