EP-3E Aries II


The EP-3E Aries II is a land-based Multi-Intelligence reconnaissance aircraft based on the P-3 Orion airframe. The EP-3E ARIES II was recently upgraded from SIGINT to Multi-Intelligence and is the Navy's only land-based reconnaissance aircraft. The EP-3 aircraft in the Navy's inventory provide fleet and theater commanders worldwide with near real-time tactical SIGINT and full motion video intelligence. With sensitive receivers and high-gain dish antennas, the EP-3E exploits a wide range of electronic emissions from deep within targeted territory. The crew fuses the collected intelligence along with off-board data and disseminates the collaborated information for direct threat warning, indications and warnings, information dominance, battle space situational awareness, suppression of enemy air defenses, destruction of enemy air-defense, anti-air warfare and anti-submarine warfare applications.
