Cryptologic Technician - Technical (CTT)
Navy Enlisted Rating (Job) Descriptions and Qualification Factors
Cryptologic Technicians (Technical) 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.
The duties performed by CTTs include:
- operating collection and analysis consoles on surface, subsurface, and airborne platforms, as well as at shore commands;
- the first line of defense against inbound threats and anti-ship missiles for deployed units;
- working with highly classified and technical material in support of national security;
- providing electronic intelligence support to commands throughout the world;
- tracking surface and airborne targets of interest to determine defensive maneuvers and tactics in case of attack;
- operating electronic detection and deception systems;
- operating state-of-the-art electronic receivers, signal modifiers, digital recording devices and associated peripherals in collection of airborne, shipborne, and land-based radar signals;
- performing in-depth technical analysis of radar signals/systems to produce technical reports and briefs for operational facilities in the United States, Hawaii, Japan, Spain, Great Britain, Australia, and various remote sites throughout the world;
- creating and maintaining technical databases used by local and national level agencies.
CTT functions are performed in clean, orderly, air-conditioned spaces, with little supervision. Personnel in the CTT ratings normally work with other intelligence and cryptology specialists on tasks that require more mental than physical effort.
