In the 1990s, the Navy had 12 Lockheed-MartinP-3Cs
converted into EP-3E ARIES II aircraft. These new planes were designed to replace the aging ARIES I aircraft, which were built in the late 1960s and early 1970s. Modifications to the EP-3E began in 1996, and the last aircraft was delivered in 1997. EP-3Es have been used for reconnaissance in support of several military operations, including support of NATO
forces in Bosnia and joint forces in Korea.

The EP-3E has four Allison T56-A14 turboprop engines, each generating 4,900 shaft horsepower to propel the plane to an average cruising speed of about 345 mph (555 kph). The four propellers, four-bladed Hamilton-Standard 54H60-77s, convert the engine's shaft horsepower into thrust. The plane is built with five fuel tanks, four wing tanks and one auxiliary tank. The auxiliary tank is a bladder-type tank located in the lower fuselage.
