Rating Badge CT.jpg Cryptologic Technician Collection 
Cryptologic Technicians control the flow of messages and information and also conduct Electronic Warfare. Their work depends on their special branch: CTAs or Administration Cryptologic Technicians (As of 01 OCT 07 CTA merged with the YN rating) perform administrative and clerical duties that control access to classified material. CTIs or Interpretive Cryptologic Technicians handle radiotelephone communications and foreign language translation. CTMs or Maintenance Cryptologic Technicians maintain electronic and electromechanical equipment. CTNs or Networking Cryptologic Technicians handle computer communication. CTRs or Collection Cryptologic Technicians handle all Morse code communications and operate radio direction/finding equipment. Finally, CTTs or Technical Cryptologic Technicians deal with Electronic Warfare. CTTs are the first line of defense against inbound threats and Anti-Ship missiles. They also collect, analyze, and provide electronic intelligence support to commands throughout the world.

Rating Description

CTR's perform a variety of duties worldwide at numerous overseas and stateside shore commands and aboard surface ships, aircraft and submarines. Duties include performing collection and analysis of state-of-the-art communication signals using sophisticated high-powered computers, specialized computer-assisted communications equipment, video display terminals and electronic/magnetic recorders.

What They Do
The duties performed by CTRs include:

•  providing in-depth analysis on a variety of complex digital communications signals using sophisticated communications equipment and computer technology to provide critical intelligence information;

•  providing analysis and technical
guidance and specialized information to weapons systems while assigned to ships and submarines;

•  possible assignment to a three-year tour of duty to selected ships homeported at Norfolk, Va., Mayport, Fla., San Diego, CA., Everett, WA, Hawaii and Japan or to P-3 aircraft based in Misawa, Japan, Whidbey Island, WA, Fallon, NV.

•  operating sophisticated state-of-the-art strategic and tactical signals collection and analysis systems;

•  locating ships, aircraft and submarines using sophisticated direction finding technology;

•  originating reports and briefs for operational commanders both ashore and afloat.

Qualifications and Interests

Qualities required of people in this rating group are good speaking and writing skills, a good memory, resourcefulness, curiosity, an adaptability to do detailed work and repetitive tasks, and an aptitude for arithmetic reasoning and record keeping.

The desire and ability to work with others as part of a team and to deal with ideas and information is also important. A talent in operating high-powered computers and electronic devices is also helpful.

Because of the nature of the duties performed, applicants for the CTR group must be of good character. Applicants must be U.S. citizens and meet eligibility requirements for continuous access to sensitive compartmented information (SCI). Eligibility for a top-secret clearance is determined by the results of a Single Scope Background Investigation followed by a reinvestigation every five years.

Recruiters can prescreen applicants and request waivers verbally when doubt of eligibility exists.

Working Environment

CTR functions are performed indoors at various shore activities and aboard ships, submarines or aircraft. Personnel may expect a clean, orderly working space, frequent contact and coordination with others and close supervision.

Career Path After Recruit Training

Enlistees are taught the fundamentals of this rating through formal Navy schooling. Advanced technical and operational training is available in career paths at later stages of career development and occasionally at the completion of the 19-week CTR "A" school.

Class "A" Technical School, Pensacola, FL. 16 of computer fundamentals, security procedures, mathematics, signals theory, digital communications technologies, equipment operations, satellite communications and fundamental reporting techniques. 

Group-paced classroom (40 percent) and lab instruction (60 percent).

Following completion of basic CTR technical training, graduates may expect assignment to shore duty or sea duty in the United States or worldwide overseas in Spain, Germany, England, Puerto Rico, Japan, or Bahrain. Fifty percent of "A" school graduates get immediate follow-on specialized "C" school training; the remainder go directly to their initial operational assignment.
