Lockheed WP-3D Orion
|NOAA Lockheed WP-3D Hurricane Hunters|
|Role||Weather reconnaissance aircraft|
|National origin||United States|
|Primary user||National Oceanic and Atmospheric Administration|
|Developed from||P-3C Orion|
The Lockheed WP-3D Orion is a highly modified P-3 Orion used by the Aircraft Operations Center division of the National Oceanic and Atmospheric Administration (NOAA). Only two of these craft exist, each incorporating numerous features for the role of collecting weather information. During hurricane season, the WP-3Ds are deployed for duty as hurricane hunters.
The WP-3Ds are equipped with three weather radars, C band radars in the nose and on the lower fuselage, and an X-band radar in the aircraft's tail. They are also equipped with dropsondes, temperature sensors, and other meteorological equipment. The aircraft are not specially strengthened for flying into hurricanes, however their decks were reinforced to withstand the additional equipment load.
It has two barber-pole samplers (named for their red-and-white stripes) which protrude from the aircraft’s front, a tail Doppler weather radar, and other unique-looking instruments hanging from the wing.
NOAA currently operates two WP-3Ds nicknamed Miss Piggy and Kermit, and their logos featuring the characters created by Jim Henson Productions. NOAA's other hurricane hunting aircraft, the Gulfstream IV-SP, is named Gonzo; they complement the fleet of WC-130 aircraft operated by the U.S. Air Force 53rd Weather Reconnaissance Squadron.
