The P-3 Orion is a four-engine turboprop patrol and research aircraft family derived from the Lockheed L-188 Electra. Its long range, large cabin, sensor capacity, and low-altitude endurance support maritime patrol, search and rescue, environmental science, weather reconnaissance, and atmospheric research. Military and civil-special-mission derivatives have served operators around the world, while NOAA's instrumented WP-3Ds remain central to tropical-cyclone observation.
