NSA's organizational designations

(Updated: February 24, 2024)

After providing lists of NSA-related codenames, abbreviations and SIGADs, we now publish a list of the designations of the numerous divisions and units of the NSA organization itself.

Unlike other intelligence agencies such as CIA or DIA, NSA never disclosed its internal organizational structure. The following overview has been reconstructed based upon information which over the years became available from various sources, including many documents from the Snowden-leaks.

This list only gives the alphanumeric designations, the official name and, if available, the logo of NSA branches. For a description of what the most important divisions do, click the links in the list or visit the websites mentioned under Links and Sources.

In 2007, the NSA had a workforce of 36,371:
- 18,849 of which were NSA civilians
- 17,522 of which were Service military/civilians*

In 2013, the following numbers of people worked for NSA/CSS:
- NSA: ca. 21,500 civilian personnel and ca. 13,500 military personnel
- CSS (tactical SIGINT collection units): ca. 12,000 military personnel

Update: In 2016, a major internal reorganization of NSA was initiated

The 2000 reorganization

In the year 2000, then director Michael Hayden reorganized much of NSA's organizational structure. For this the NSA Transformation Office (NTO) was established and the Directorate of Operations and the Directorate of Technology were merged into the Signals Intelligence Directorate (SID).

Also new officers were appointed, like a Chief Financial manager, a Chief Information Officer (CIO), a Senior Acquisition Executive (SAE) and a Transformation Officer. Around the same time, many NSA divisions and units got new designations.

Also in 2000, a Senior Leadership team was formed, consisting of the Director (DIRNSA), the Deputy Director and the Directors of the Signals Intelligence (SID), the Information Assurance (IAD) and the Technology Directorate (TD). The chiefs of other main NSA divisions became Associate Directors of the Senior Leadership team.

   
The 2016 reorganization

In 2016, NSA director Michael Rogers initiated a reorganization under the name NSA21, which has to prepare the agency for "cyber" challenges. One of the most important changes will be to replace the Signals Intelligence (SID) and Information Assurance (IAD) directorates by a new Directorate of Operations that combines the operational elements of each. The hacking division Tailored Access Operations (TAO) has been renamed into Computer Network Operations. NSA21 reached full operational capability in December 2017.

Also the other existing branches will be reorganized into the following 6 new directorates:

- Workforce and Support Activities
- Business Management and Acquisition
- Engagement and Policy
- Operations
- Capabilities
- Research
