Job Description
Cryptologic Technicians – Interpretive (CTI) are Navy enlisted Sailors who use their skills in foreign languages, cultural knowledge, and technology to assist in strategic, tactical, and cyber information operations. Their duties include collecting, processing, analyzing, and reporting on foreign language communications, digital network information, and Signals Of Interest (SOI) to identify, locate, and monitor potential threats around the world.
CTIs transcribe, translate, and interpret foreign languages. They run foreign language programs. They help Navy, Joint Force, and national teams understand different cultures and regions. They also handle classified info, making sure it stays secure.
They work everywhere—shore commands, ships, aircraft, submarines. Sometimes in an office, sometimes in the field. Clean desks, high-tech labs, or moving platforms at sea.
One day, they’re scanning foreign transmissions in a quiet room. The next, they’re mid-mission, decoding what’s critical. Commanders rely on them. The mission depends on them.
Some work solo. Some in tight-knit teams. They answer to Cryptologic Warfare Officers and Cyber Warfare Engineers, the ones with four-year degrees.
Their work isn’t just about language—it’s about knowing what’s coming next. They get annual training to keep their skills sharp, sometimes on land, sometimes deployed.
There are about 1,800 CTIs in the Navy today.
