Mission
Four-engine turboprop signals intelligence (SIGINT) reconnaissance aircraft.
Background
During the 1990s twelve P-3Cs were converted to EP3-E ARIES II to replace older versions of the aircraft. The original ARIES I aircraft were converted in the late 1960s and early 1970s. The last EP-3E ARIES II aircraft was delivered in 1997. EP-3Es have been heavily engaged in reconnaissance in support of NATO forces in Bosnia, joint forces in Korea and in Operation Southern Watch, Northern Watch, and Allied Force.
Features
The EP-3E ARIES II (Airborne Reconnaissance Integrated Electronic System II) is the Navy’s only land-based signals intelligence (SIGINT) reconnaissance aircraft. The 11 aircraft in the Navy’s inventory are based on the P-3 Orion airframe and provide fleet and theater commanders worldwide with near real-time tactical SIGINT. With sensitive receivers and high-gain dish antennas, the EP-3E exploits a wide range of electronic emissions from deep within targeted territory.
