Overview
ECHELON is a surveillance program (signals intelligence/SIGINT collection and analysis network) operated by the five signatory states to the UKUSA Security Agreement: Australia, Canada, New Zealand, the United Kingdom, and the United States - collectively known as the Five Eyes (FVEY).
By the end of the 20th century, the Five Eyes had developed ECHELON into a global system capable of collecting massive amounts of private and commercial communications including telephone calls, fax, email, and other data traffic. The system uses a network of ground stations, satellites, and tapping into undersea fiber optic cables to intercept communications worldwide.
While initially designed to monitor the military and diplomatic communications of the Soviet Union and Eastern Bloc, ECHELON evolved to intercept virtually all global communications. The program remained officially secret until the late 1990s, when investigations by journalists and the European Parliament confirmed its existence.
"The existence of a global system for intercepting communications, operating by means of cooperation proportionate to their capabilities among the US, the UK, Canada, Australia and New Zealand under the UK-USA Agreement, is no longer in doubt."
- European Parliament Investigation Report, 2001
History & Timeline
World War II Origins
British and American codebreakers establish informal cooperation at Bletchley Park. The relationship forms the foundation for post-war intelligence sharing.
UKUSA Agreement Signed
The United Kingdom - United States of America Agreement (UKUSA) formalizes signals intelligence cooperation. Canada, Australia, and New Zealand join as "second party" members.
Satellite Interception Begins
Following the establishment of Intelsat, plans begin for intercepting satellite communications. Ground stations are constructed worldwide.
ECHELON Network Established
The first ECHELON network reportedly becomes operational, linking interception stations across Five Eyes countries.
First Public Revelation
Journalist Duncan Campbell publishes "Somebody's Listening" in the New Statesman, first revealing ECHELON's existence and its use for corporate espionage.
Nicky Hager Investigation
New Zealand journalist Nicky Hager publishes "Secret Power," documenting New Zealand's role in ECHELON based on insider sources.
European Parliament Investigation
The European Parliament establishes a special committee to investigate ECHELON following concerns about economic espionage against European companies.
EP Report Published
European Parliament report concludes that ECHELON exists and was being used for economic espionage in addition to security purposes.
Snowden Revelations
Edward Snowden leaks massive trove of NSA documents revealing the full scope of Five Eyes surveillance, including programs like PRISM, XKeyscore, and Tempora.
Ongoing Revelations
Continued release of Snowden documents reveals additional surveillance programs, partnerships with tech companies, and the true scale of global interception.
Five Eyes Structure
The Five Eyes alliance divides global surveillance responsibilities geographically, with each member nation responsible for specific regions:
United States (NSA)
National Security Agency
Largest partner. Responsible for Western Hemisphere, Asia, eastern Russia, and northern China. Operates the most extensive global surveillance infrastructure.
United Kingdom (GCHQ)
Government Communications HQ
Responsible for Europe (including western Russia) and Africa. Operates the TEMPORA program intercepting fiber optic cables.
Canada (CSE)
Communications Security Establishment
Focuses on Latin America, northern Russia, and parts of China. Key location for intercepting communications crossing North America.
Australia (ASD)
Australian Signals Directorate
Responsible for Indochina, Indonesia, and southern China. Major facility at Pine Gap monitors satellite communications.
New Zealand (GCSB)
Government Communications Security Bureau
Covers South Pacific and Southeast Asia. Waihopai Station intercepts satellite communications for the network.
Extended Alliances
Beyond Five Eyes, additional intelligence sharing arrangements exist:
- Nine Eyes: Five Eyes plus Denmark, France, Netherlands, Norway
- Fourteen Eyes: Nine Eyes plus Germany, Belgium, Italy, Spain, Sweden
- Other Partners: Israel, Japan, South Korea, and Singapore have varying arrangements
Surveillance Programs
The Snowden revelations exposed numerous surveillance programs operating under the Five Eyes framework:
NSA Programs (United States)
- PRISM: Direct access to data from Google, Facebook, Apple, Microsoft, and other tech companies
- XKeyscore: System for searching and analyzing internet data collected worldwide
- MUSCULAR: Tapping Google and Yahoo data center links
- MYSTIC: Recording entire countries' phone calls for 30-day retrieval
- MARINA: Database storing internet metadata for up to one year
- PINWALE: Repository for email and other content
- BULLRUN: Efforts to defeat encryption technologies
GCHQ Programs (United Kingdom)
- TEMPORA: Tapping undersea fiber optic cables carrying internet traffic
- INCENSER: Bulk collection from fiber optic cables
- EDGEHILL: British counterpart to NSA's BULLRUN encryption defeat program
Joint Operations
- DAPINO GAMMA: Joint NSA/GCHQ operation hacking SIM card manufacturer Gemalto
- AURORAGOLD: Surveillance of global mobile network operators
- Quantum programs: Hacking operations using man-in-the-middle attacks
Scale of Collection
According to Snowden documents, the NSA collects and processes over 200 million text messages daily, taps into the links between Google/Yahoo data centers, and has the capability to record entire countries' phone systems. GCHQ's TEMPORA system can store three days of all internet traffic passing through UK fiber optic cables.
How ECHELON Works
The ECHELON system intercepts communications through multiple methods and processes them using sophisticated filtering technology.
Collection Methods
- Satellite Ground Stations: Large dish antennas at sites like Menwith Hill (UK), Pine Gap (Australia), and Bad Aibling (Germany) intercept satellite communications
- Undersea Cable Taps: Devices attached to fiber optic cables intercept internet traffic at key chokepoints
- Embassy Collection: Equipment in diplomatic missions intercepts local communications
- Tech Company Partnerships: Direct access to data through programs like PRISM
- Internet Backbone Access: Taps at major internet exchange points
Processing & Analysis
Raw intercepts are processed through sophisticated systems:
- Dictionary Computers: Supercomputers scan all communications for keywords, phrases, names, phone numbers, and email addresses on target lists
- Voice Recognition: Systems can identify specific voices across intercepted phone calls
- Pattern Analysis: Metadata analysis identifies communication patterns and social networks
- XKeyscore: Allows analysts to search through collected data using various criteria
Key Interception Facilities
- Menwith Hill (UK): Largest NSA facility outside the US, primary European collection point
- Pine Gap (Australia): Major satellite interception facility
- Waihopai (New Zealand): South Pacific satellite interception
- GCHQ Bude (UK): Taps transatlantic fiber optic cables
- Fort Meade (US): NSA headquarters and primary data processing center
Documentary Evidence
ECHELON's existence is now thoroughly documented through official investigations, leaked documents, and government admissions.

Book PublicationImplications & Concerns
The existence of global mass surveillance raises profound questions about privacy, democracy, and the rule of law.
Privacy Violations
- Collection of private communications of billions of people worldwide without individual warrants
- No effective oversight by courts or legislatures in most cases
- Metadata collection reveals intimate details of personal lives, associations, and movements
- Data retention allows retroactive surveillance of individuals
Democratic Concerns
- Surveillance of journalists, lawyers, and human rights organizations
- Chilling effect on free speech and association
- Ability to monitor political opponents and dissidents
- Secret programs hidden from democratic oversight for decades
Economic Espionage
The European Parliament investigation found evidence that ECHELON was used for economic espionage to benefit American and British companies. Specific allegations include:
- Airbus losing a $6 billion contract to Boeing after NSA intercepts
- Thomson-CSF losing a $1.4 billion Brazilian deal to Raytheon
- German wind energy company Enercon's technology allegedly stolen
Legal Workarounds
Five Eyes partners allegedly spy on each other's citizens and share the data, circumventing domestic surveillance laws. For example, GCHQ might collect data on American citizens (legal under UK law) and share it with the NSA, avoiding US Fourth Amendment protections.
