Understanding Security Classifications in the United States

In the United States, the classification levels for national security information are categorized into several tiers. These tiers include Confidential, Secret, Top Secret, and specific subcategories that further define and restrict access to sensitive information. This article delves into these classification levels, particularly focusing on whether there exists any security level above Top Secret and explores the unique classification levels that go beyond it.

The Standard Classification Levels

The standard classification levels for sensitive information in the US are as follows:

Confidential: Information that could cause damage to national security if disclosed. Secret: Information that could cause serious damage to national security if disclosed. Top Secret: Information that could cause exceptionally grave damage to national security if disclosed.

Beyond Top Secret

While there is no official classification level higher than Top Secret, the United States has implemented special classification levels that require even stricter access controls and oversight. These special classifications often involve additional layers of clearance and security procedures. Letrsquo;s explore some of these unique classifications.

Sensitive Compartmented Information (SCI)

The Sensitive Compartmented Information (SCI) designation is a special classification that indicates information requiring special access controls and is compartmentalized within the Top Secret level. This level is designed for information that is highly sensitive and potentially critical for national security. While it does not constitute an official classification level above Top Secret, it is a significant designation that further restricts access to sensitive information.

Special Access Programs (SAP)

Special Access Programs (SAP) are highly sensitive government programs that require additional security measures and access controls beyond those for Top Secret information. SAP involves enhanced security procedures, temporary clearances, and specialized clearances. These programs often involve information that is so sensitive that it cannot be released even under Top Secret clearance.

The Double Top Secret Classification

In the history of the United States, there have been instances of information being classified as ldquo;Double Top Secret.rdquo; This classification refers to particularly sensitive information, such as that involved in the Manhattan Project, where the development of nuclear weapons required the utmost secrecy. Similarly, certain nuclear war plans and early ICBM decoys were also classified as Extremely Sensitive Information (ESI).

Project FURTHERANCE and Born Secret

One of the most extreme examples of information that is so secret it lacks an official security level is Project FURTHERANCE. This project relates to the authority to release nuclear weapons in an emergency. Unlike most classified information, there is no specific security level for this project, highlighting just how sensitive and critical the information is. Another example is the early US ICBM decoys (Atlas D/E/F and Titan I), which were so secret that they did not even have a security classification.

Different Types of Top Secret Clearances

While all Top Secret clearances provide access to highly sensitive information, there are different types of Top Secret clearances, including:

Non-Compartmentalized Top Secret (TS): This type of clearance grants access to the majority of Top Secret information. Compartmentalized Top Secret (TS Compartmentalized): This type of clearance is more restrictive and grants access only to specific subsets of Top Secret information. SCI (Sensitive Compartmented Information): This designation is used for information that requires special access controls and is compartmentalized within the Top Secret level.

Some Top Secret clearances may be particularly high, known as ldquo;Born Secretrdquo; clearances, which are required for access to the most sensitive information. These clearances often include both compartmentalized and non-compartmentalized elements, making them the most stringent of all.

Conclusion

While there is no official security classification level above Top Secret, the US has developed special classification levels such as Sensitive Compartmented Information (SCI) and Special Access Programs (SAP) to further restrict access to highly sensitive information. These levels, along with historical examples like ldquo;Double Top Secretrdquo; and ldquo;Born Secretrdquo; clearances, demonstrate that the need for extreme secrecy extends beyond the standard classification tiers, ensuring the highest levels of protection for the most sensitive information.
