Cryptologic Technician (CT) is a United States Navy enlisted rating or job specialty. The CT community performs a wide range of tasks in support of the national intelligence-gathering effort, with an emphasis on cryptology and signal intelligence related products.
Most CT personnel are required to obtain and maintain security clearances. Due to the highly classified and secure work environment requiring very restricted access, it is not always possible to share resources with other commands, leading to their shipboard nickname, "spooks". Almost every detail surrounding the CT world from administration to operations to repair requires dedicated technicians with appropriate security clearances (this accounts for the many branches of the CT rating, i.e. CTI, CTM, CTN, CTO, CTR, CTT). The contribution of an individual CT will depend upon the branch or career area.
Members of the CT community enjoy a wide range of career and training options. Once trained, a CT might serve ashore, afloat, or in an airborne capacity. Some CT sailors can expect overseas assignments of lengthy duration and some may never travel overseas.
- Administration (CTA) - Administrative and clerical duties that control access to classified material such as Special Security Officer (SSO) or Defense Courier Service (DCS). (No longer active.)
- Interpretive (CTI) - Interpretive are the Navy's linguists. They specialize in analysis of adversary developments, radiotelephone communications, and preparation of statistical studies and technical reports requiring knowledge of a foreign language.
- Maintenance (CTM) - the installation, configuration, diagnosis, and repair of state-of-the-art electronic, computer, and network hardware and software systems.
- Networks (CTN) - perform a variety of duties associated with computer network operations across global networks. A combination of technical and analytical computer network skills provides the situational awareness required to plan and execute information operations (IO) actions/ counteractions. (Rating was established from NEC Codes: 9301, 9302, 9303)
- Collection (CTR) – perform a variety of duties worldwide at numerous overseas and stateside shore commands, aboard surface ships, aircraft, submarines, and Naval Special Warfare. Duties include performing collection, analysis, and reporting on communication signals using computers, specialized computer-assisted communications equipment, video display terminals, and electronic/magnetic tape recorders.
- Synonymous with US Army job specialty 35S (Signals Collection Analyst) and US Marine MOS 2621 (Special Communications Signals Collection Operator)
- Technical (CTT) - perform a variety of specialized duties associated with the collection and processing of airborne, shipborne, and land-based radar signals. They operate electronic intelligence receiving and direction finding systems, digital recording devices, analysis terminals, and associated computer equipment. Systems they operate produce high-power jamming signals used to deceive electronic sensors and defeat radar guided weapons systems. Additionally, intelligence derived from collection and processing update national databases which are crucial to tactical and strategic units throughout the world. Non-communications signals intelligence (ELINT), Electronic Warfare Support (ES), Electronic Attack (EA), Electronic Protect (EP), Anti-Ship Missile Defense (ASMD), while a portion perform servicing and maintenance of various related electronic countermeasures systems (i.e., AN/SLQ-32) They can hold Navy Enlisted Classification such as 1702, 1733, 1734, 1736, 1737 which are primarily for the AN/SLQ-32, 8201, 8295, 8296 which are for Naval Aircrewman, 9135 for Subsurface, 1781 advanced apps, and also the 9141,9102 NEC's.
