Description: Lockheed four-engine
propeller aircraft used as a submarine hunter and for surface surveillance.
Features: The P-3C is a land-based, long range anti-submarine warfare (ASW)
patrol aircraft. It has advanced submarine detection sensors such as directional frequency
and ranging (DIFAR) sonobuoys and magnetic anomaly detection (MAD) equipment. The avionics
system is integrated by a general purpose digital computer that supports all of the
tactical displays, monitors and automatically launches ordnance and provides flight
information to the pilots. In addition, the system coordinates navigation information and
accepts sensor data inputs for tactical display and storage. The P-3C can carry a mixed
payload of weapons internally and on wing pylons.
Background: In February 1959, the Navy awarded Lockheed a contract to develop a
replacement for the aging P-2 Neptune. The P-3V Orion entered the inventory
in July 1962, and over 30 years later it remains the Navy's sole land-based antisubmarine
warfare aircraft. It has gone through one designation change (P-3V to P-3) and three major
models: P-3A, P-3B, and P-3C, the latter being the only one now in active service. The
last Navy P-3 came off the production line at the Lockheed plant in April 1990.
