The EP-3E Airborne Reconnaissance Integrated Electronics System (ARIES) II is a land-based multi-intelligence reconnaissance aircraft based on the P-3 Orion airframe. A total of 12 P-3C Non-Update (NUD) aircraft were converted to replace older versions of the aircraft, which had been converted in the late 1960s and early 1970s. By the mid-1980s, the EP-3E Conversion-In-Lieu of Procurement program authorized the conversion of these 12 P-3C aircraft into EP-3E ARIES II aircraft, extending their service life into the 21st century.
The EP-3E ARIES II can work alone or be part of a battle group. The aircraft provides the capability to detect and exploit tactically significant electronic signals and communication Signal Intelligence (SIGINT) information to the appropriate battle group commanders. It provides near real-time tactical electronic reconnaissance capability for battle group indications and warnings, targeting, suppression of enemy air defenses, and strike sorties. Upgraded with sensitive receivers and high-gain dish antennas, the EP-3E can exploit a wide range of electronic emissions from deep within enemy territory.
Service History
EP-3E ARIES II, SN 156511, was built by Lockheed as a P-3C and was assigned to Patrol Squadron 30 (VP-30) on June 28, 1969. A decade-and-a half later, June 15, 1984, the aircraft was transferred to VP-50 where it remained until January 24, 1985. It was then transferred to VP-30 until August 29, 1986, when it entered the EP-3E Conversion-In-Lieu of Procurement program at the Logistic Aircraft Center at Greenville, S.C. Fleet Air Reconnaissance Squadron VQ-1, Whidbey Island, received 156511 after its conversion to an EP-3 ARIES II aircraft in April 1991.
On April 1, 2001, the aircraft was involved in an international incident when a midair collision occurred with a Chinese Air Force F-8 II jet. Forced to make an emergency landing at Hunshui airport, Hainan Island, China, the crew was held for several days before being repatriated separately to the United States while the aircraft remained in China. After being disassembled by Lockheed Martin, the aircraft was transported by an AN-124 to Dobbins ARB, GA.
After major repairs, it returned to flying status with VQ-1 on November 15, 2002. In October 2009 VQ-2 received 156511 for flight operations. It was transferred to VQ-1 in February 2012. On October 21, 2024, it was flown into Davis Monthan AFB. Three days later it was moved to Pima Air & Space Museum for display.
