OVERVIEW

Cryptologic Technician (CT) is the U.S. Navy's parent rating identifier for striker-tier Sailors entering the cryptologic and information-warfare community before being designated into one of the five CT sub-ratings: CTI (Interpretive/linguist), CTR (Collection), CTT (Technical/ELINT), CTM (Maintenance), or CTN (Networks/cyber). The CT designator is used in PRIDE personnel records during the security-clearance and aptitude-screening phase.

The cryptologic / information warfare community conducts signals intelligence, cyberspace operations, and electronic warfare for U.S. Cyber Command, the National Security Agency, and Fleet Cyber Command / Tenth Fleet. All cryptologic ratings require a TS/SCI clearance, polygraph eligibility, and intensive language, technical, or analytic training at the Center for Information Warfare Training (CIWT).

A-school for the rating runs Sub-rating school 22–64 weeks after striker designation at CT-striker pipeline routes accessions to CTI / CTR / CTT / CTM / CTN A-schools at Corry Station, Pensacola FL based on aptitude and clearance., where Sailors complete the technical foundation needed to report to their first fleet command. Entry requires the ASVAB line score VE+AR=109 (TS/SCI required) and an enlistment obligation of 6–6 years. CTs advance through the standard enlisted paygrade structure (E-1 through E-9), competing in the Navy-Wide Advancement Examination (NWAE) at E-4 through E-6 and via the Selection Board at E-7 through E-9. Senior CTs typically serve as Leading Petty Officer (LPO), Work Center Supervisor, Leading Chief Petty Officer (LCPO), or Command Master Chief (CMC), and may pursue Limited Duty Officer (LDO), Chief Warrant Officer (CWO), or commissioning programs such as STA-21, MECP, or OCS.

Across the active force, CT Sailors are essential to the Navy's mission readiness, and the rating remains an in-demand career field with strong reenlistment bonuses (SRB), advancement opportunities, and pathways into Navy Reserve, civilian DoD, and industry careers after service.

RESPONSIBILITIES

  • CT-strikers complete TS/SCI clearance adjudication, take the Defense Language Aptitude Battery (DLAB) for CTI consideration, and complete preparatory cryptologic instruction at Corry Station before designation into a CT sub-rating.
  • Stand watches and qualify on the rating's Personnel Qualification Standards (PQS), maintain training jackets, and mentor junior CTs as required by the chain of command.

HISTORY

The Cryptologic Technician (CT) rating dates to 1948 (as Communications Technician), was renamed Cryptologic Technician in 1976, and split into the modern five sub-ratings. The CT parent identifier persists for striker-tier accession tracking.

The cryptologic community traces to OP-20-G — the Navy's World War II signals-intelligence organization that broke the Japanese JN-25 code and contributed to the victory at Midway. Post-war the community evolved through the Communications Technician (CT) ratings, was reorganized in 1976, and again restructured in 2008 into the modern CTI/CTM/CTN/CTR/CTT specialties under the Information Warfare community.

Today the Cryptologic Technician (Striker) (CT) rating is overseen by the Enlisted Community Management (ECM) office at My Navy HR and the Center for Personal and Professional Development. Modern CTs benefit from the Sailor 2025 personnel-system reforms, the Ready Relevant Learning (RRL) training continuum, and credentialing through the Navy COOL program — turning rating qualifications into industry-recognized certifications and licenses.

The rating's structure, training pipeline, and operational employment continue to evolve alongside the Navy's transition to Distributed Maritime Operations (DMO), Project Overmatch, and the Force Design 2045 fleet architecture, ensuring CTs remain central to the warfighting mission.
