24 Sailors Vacuum Up Global Signals in EP-3E ARIES II
By Marcus Boone ·
Sailors spend 12-hour shifts hovering on the edges of sovereign airspace to intercept foreign signals, a mission that carries the constant risk of drifting across a border.
A wingspan of 99 feet, 8 inches and a length of 105 feet, 11 inches. That is the physical footprint of the EP-3E ARIES II, a four-engine, low-wing aircraft designed for the singular purpose of electronic warfare and reconnaissance. According to a program description mirrored by the FAS Intelligence Resource Program, this machine is not merely a transport for personnel, but a platform for "state-of-the-art electronic surveillance equipment."
It is a conversion of the P-3, which the FAS record notes was derived from the "ill-fated turboprop-powered Electra airline." While the commercial version of the aircraft struggled, the military adaptation thrived by trading passenger comfort for the ability to vacuum up signals from the ether. The ARIES II is built for the long haul, boasting a "12+ hour endurance" and a range exceeding 3,000 nautical miles. This allows the aircraft to linger in the air, hovering on the edges of sovereign airspace, listening to whatever the wind—or the radio frequency—carries.
12+ Hour Endurance
The scale of the operation is not just found in the aircraft's range, but in its interior. The FAS catalogue entry describes 24 numbered seating positions, 19 of which are dedicated crew stations. To operate a machine of this complexity requires a precise social and professional hierarchy. The normal complement is 24 people: seven officers and 17 enlisted aircrew.
While the flight deck is manned by the standard trinity of three pilots, a navigator, and a flight engineer, the belly of the plane is where the actual work of surveillance happens. The record notes that the remainder of the crew consists of equipment operators, technicians, and mechanics. It adds a clarifying detail that "not all members of the crew are intelligence specialists," suggesting a divide between those who keep the plane in the air and those who interpret the data flowing into the stations.
For the specialized officers and enlisted personnel of VQ-2, the Navy employs a specific lexicon to categorize their "unique talents." They are not merely sailors; they are Electronic Warfare Mission Commanders (EWMC), Electronic Warfare Aircraft Commanders (EWAC), Senior Electronic Warfare Tactical Evaluators (SEVAL), and Electronic Warfare Operators (EWOP). These titles define a rigid professional structure dedicated to the art of the intercept.

EWMC and SEVAL
The ARIES II does not operate in a vacuum. The FAS record contrasts it with the P-3C Update III, a multi-mission aircraft. Where the P-3C is a weaponized tool—capable of carrying the Harpoon anti-surface missile, the MK-50 torpedo, and the MK-60 mine for anti-submarine warfare—the EP-3E is a tool of information. The P-3C Update III may support carrier battle groups or amphibious readiness groups, but the ARIES II supports the intelligence community.
The transition to this capability was a gradual replacement of older technology. The first EP-3 Aries I joined Fleet Air Reconnaissance Squadron ONE in 1969, starting a program to replace the Super Constellations that concluded in 1974. The shift from the piston-driven era to the Allison T56-A-14 turboprops represented more than just a speed upgrade; it represented a professionalization of aerial spying.

Western Pacific and Indian Oceans
The reach of this surveillance is global. The record explains that each Navy Maritime Patrol Aviation (MPA) Electronic Warfare (VQ) squadron consists of nine aircraft and is staffed by roughly 60 officers and 250 enlisted personnel. These squadrons do not remain stationary. They deploy to sites in the Western Pacific, the Indian Ocean, and the Atlantic Ocean for approximately six months at a time.
This rotation ensures a permanent, rotating presence of electronic warfare capabilities across the world's most contested waters. After six months of monitoring signals in a foreign theater, the crews return home for a year of training. It is a cycle of observation and preparation, designed to keep the "state-of-the-art" equipment tuned to the frequencies of the day.
Public records, such as the Wikipedia lead for the Lockheed EP-3, establish that the aircraft is an electronic signals reconnaissance variant of the P-3 Orion. The FAS mirror provides the technical anatomy of that reconnaissance, detailing a machine that is essentially a flying sensor array.
Other archives hold related files that provide a broader context to these operations. NSArchive maintains records from the United States District Court for the Northern District of Illinois dated August 19, 2025, and an Annual Threat Assessment from the Office of the Director of National Intelligence from March 2025. There is also the documented history of downed pilots, such as the 2003 account of Shane Osborn, which serves as a reminder of what happens when these reconnaissance flights drift too far across a border.
As for the specifics of how these crews are trained to handle the signals they intercept, the FAS mirror lists several resources that it does not provide in full: the Navy Training System Plan for the EP-3E Aircraft from February 2003, the Sensor System Improvement Program from January 2001, and the Joint Signal Intelligence Avionics Family Modernization from June 2001. These documents, created by John Pike and maintained by Steven Aftergood, point toward a modernization effort at the turn of the century that sought to refine the way the US Navy listens to the world.
