Cryptologic Technicians – Technical (CTTs) track, jam, and disrupt enemy signals. They work in Electronic Warfare (EW)—running electronic sensors, analyzing radar signals, collecting ELINT, and making sure commanders get the intel they need.

Their job? Detect threats before they happen. Whether it’s missile defense, information warfare, or tactical support for special warfare teams, CTTs make sure the fleet stays a step ahead.

CTTs serve everywhere—on ships, aircraft, submarines, shore commands, and with Naval Special Warfare. They work in high-tech, secure environments, usually alone or in small teams, solving complex problems with minimal supervision.

This is a small, elite community—only about 3,000 Sailors—with missions that directly impact national security. Their career path? Signals intelligence, radar tracking, high-level reporting, operational facility management, and even instructing the next generation of cryptologic specialists.

Specific Responsibilities

CTTs specialize in radar signals from the air, land, and sea. Their job includes:

  • Running electronic sensors, recording devices, and intel analysis systems
  • Jamming enemy radars and disrupting missile guidance systems
  • Providing intel and tactical support to surface, subsurface, air, and special warfare teams

They see the threats before anyone else does.

Operational Electronic Intelligence Analyst (OPELINT)

Collects and analyzes foreign radar and electronic signals. Tracks enemy weapons systems, vulnerabilities, and trends to provide tactical and strategic commanders with real-time intelligence.

Surface Electronic Warfare Maintainer

Keeps Electronic Warfare (EW) systems running. Installs, tests, repairs, and troubleshoots radar jammers, antennas, Decoy Launching Systems (DLS), and digital/optical interfaces. If it breaks, they fix it fast.

Surface Electronic Warfare Operator

Uses radar receivers, recording devices, and electronic warfare systems to track and identify enemy signals. Analyzes intercepted signals, provides early warning intel, and sends reports up the chain to support tactical operations and fleet security.

Tactical Information Operations Specialist

Handles special ops electronic warfare. Works alongside SEALs and Special Operations Forces (SOF), maintaining and repairing electronic systems for ground and airborne missions. Fabricates custom surveillance gear, collects critical battlefield intelligence, and runs direct-action support missions.

Technical Electronic Intelligence Analyst (TECHELINT)

Breaks down non-communication signals. Tracks and deciphers foreign weapons systems, providing assessments on threat capabilities, weaknesses, and patterns. Helps commanders stay ahead of enemy technology.

If the Navy needs to know what’s happening in the electromagnetic spectrum, these are the experts making sure nothing goes unseen.

Training and Career Opportunities

Training Path

After Boot Camp at Great Lakes, new Cryptologic Technicians Technical (CTTs) head to Pensacola, FL, for specialized training at Class “A” School (12 weeks).

Here, they learn:

  • Radar system theory and how different systems operate
  • Electronic intelligence analysis and tracking enemy radar signals
  • Operating high-tech collection devices (both analog and digital)
  • Using radar analysis equipment to break down signal patterns
