The Lockheed P-3 Orion is a patrol aircraft of the United States military used primarily for anti-submarine warfare.

Design

The P-3 Orion is based on the Lockheed L-188 Electra. The first production version, designated P3V-1, first flew 15 April 1961, but by the time the first deliveries were made in 1962, the unified designation system made this the P-3.

Over the years, many variants have been developed.

The P-3 Orion has found special use as an earth-science suborbital research platform for NASA. Known as callsign NASA 426, this aircraft is located at Goddard Space Flight Center's Wallops Island Flight Facility, Virginia.

The P-3 is slated for replacement between 2010-2013 by the Boeing MMA, based upon their 737 civilian aircraft. Australia is considering both the MMA and a navalized version of the Global Hawk as a replacement.
