Signals Intelligence (SIGINT): What It Is and Why You Should Care
Signals Intelligence (SIGINT) is a vital window into our foreign adversaries’ capabilities, actions, and intentions. SIGINT can be used to collect intelligence on potential threats from communications systems or radars which may give us insight into an enemy’s plans before they are carried out in order to create protection against these attacks.

In this article, we will discuss the history of SIGINT, its importance to the military today, some examples of how it has been used in the past to provide valuable intelligence as well as more recent uses. We’ll also look at differences between Signals Intelligence and other types of intelligence collection methods. Finally, we’ll look at what the future might hold for SIGINT given current technological trends.
What is the history of Signals Intelligence (SIGINT)?
SIGINT is an old concept that dates back to before the American Civil War. The Signal Corps (1860) was created to support the military operations of the United States by performing like a communications department. In modern times SIGINT has become popular because it’s a way to collect information without having boots on the ground.
The use of SIGINT has increased in recent years due to the rise of digital communication. This has made it much easier to collect and process information. However, it also means that privacy concerns are more prevalent than ever before.
Despite the concerns, SIGINT remains an essential part of national security and defense. It’s been used effectively in many different conflicts and will continue to play a critical role in the future.
Why is Signals Intelligence (SIGINT) so important today?
SIGINT is important due to the fact that it can help us protect our country by providing valuable information about potential threats. By listening to the conversations of foreign powers, we can get an inside look at their plans and intentions that could put America in danger. With this information, our government is able to act accordingly by taking steps to ensure national security.
SIGINT has a variety of other purposes such as monitoring communications, tracking the movement of people or vehicles, and even identifying targets. This incredibly valuable tool provides the insight into the activities of our allies, enemies, or other adversaries needed to maintain our strategic advantage.
Examples of SIGINT would include the interception of telephone calls or emails and the use of satellites to capture pictures or video footage. In recent years, social media has also become an important source of SIGINT. By monitoring platforms like Facebook and Twitter, intelligence agencies can learn a lot about the activities of foreign powers.
What are the Sub-disciplines of Signals Intelligence (SIGINT) – COMINT, ELINT, and FISINT.
Communications Intelligence (COMINT):
Communications Intelligence is the gathering of information from intercepted communications. This can include telephone calls, emails, text messages, and any other form of electronic communication.
Electronic Intelligence (ELINT):
Electronic Intelligence is the gathering of information from electronically-generated signals. This can include radar signals, sonar signals, and any other form of electronic communication.
Foreign Instrumentation Signals Intelligence (FISINT):
Foreign Instrumentation Signals Intelligence is the gathering of information from intercepted communications that are not related to computers or electronics. This can include rocket telemetry data as well as foreign weapons systems such as aircraft and ships.
What are some differences between Signals Intelligence (SIGINT) and other types of intelligence collection methods?
The biggest difference is that SIGINT can give us insight into an enemy’s plans before they are carried out, whereas other intelligence collection methods might provide information after an attack has already taken place.
What is the difference between SIGINT and Sigkill?
Sigkill is the process of using SIGINT to gain intelligence about an enemy’s capabilities, actions, and intentions.
What are some examples of Sigkill? An example would be the use of SIGINT to determine if an enemy has the ability to launch a nuclear attack.
What is the difference between SIGINT and Sigstop?
Sigstop is the process of using SIGINT to stop an enemy’s communications.
What are some examples of Sigstop? An example would be the use of SIGINT to disable an enemy’s telephone or email communications.
What is the difference between SIGINT and EW?
EW is the use of electronic warfare to protect our forces from being attacked by enemy electronics, whereas SIGINT is the use of signals intelligence to gain information about the enemy.
What are some examples of EW? An example would be using a radar jammer to prevent an enemy from detecting our forces.
What is the difference between SIGINT and MASINT?
MASINT is the use of measurement and signature intelligence to identify, characterize, and track targets, whereas SIGINT is the use of signals intelligence to gain information about the enemy.
What are some examples of MASINT? An example would be using acoustic sensors to detect the sound of a submarine.
What is the difference between SIGINT and IMINT?
IMINT is the use of image intelligence to gain information about the enemy, whereas SIGINT is the use of signals intelligence to gain information about the enemy.
What are some examples of IMINT? An example would be using satellites to capture pictures or video footage of the enemy.
What is the difference between SIGINT and HUMINT?
HUMINT is the use of human intelligence to gain information about the enemy, whereas SIGINT is the use of signals intelligence to gain information about the enemy.
What are some examples of HUMINT? An example would be interrogating prisoners of war to learn more about the enemy’s plans and intentions.
What is the difference between SIGINT and OSINT?
OSINT is the use of open source intelligence to gain information about the enemy, whereas SIGINT is the use of signals intelligence to gain information about the enemy.
What are some examples of OSINT? An example would be using publicly available information about the enemy on social media websites.
What is the Difference between SIGINT and Radar?
Radar is the use of radio waves to detect and track objects, whereas SIGINT is the interception of signals.
What are some examples of radar? An example would be the use of radar to detect an enemy aircraft.
What is the future of Signals Intelligence (SIGINT)?
SIGINT will continue to play a critical role in our intelligence efforts. It is essential that we have the ability to intercept and analyze enemy signals in order to gain information about their capabilities, actions, and intentions. We must also be able to use SIGINT to stop their communications and protect our forces from being attacked by their electronics.
The future of Signals Intelligence (SIGINT) is bright. With new technologies and methods, we are constantly finding new ways to gather information about the enemy. This vital tool will continue to play a key role in our national security strategy.
