Job Description
The Information System Technician – Submarines (ITS) are Navy enlisted Sailors who perform various functions related to communications operations, message processing, network administration, and cybersecurity aboard U.S. Navy submarine vessels.
A submarine is only as strong as its data. Every mission depends on secure networks, encrypted comms, and real-time intelligence. Information Systems Technicians—Submarines (ITS) make sure that nothing fails, nothing leaks, and nothing is lost.
What They Do
ITSs secure, defend, and maintain the Navy’s most critical digital systems. From global satellite communications to classified intelligence networks, they ensure information flows without interruption.
- Radio Frequency (RF) Communications & Spectrum Management – Control all incoming and outgoing messages.
- Satellite Telecommunications – Manage secure, worldwide comms for mission success.
- Network Administration & Security – Build, operate, and defend IT systems on submarines.
- Electronic Warfare Systems – Maintain and safeguard cryptographic and communication security equipment.
- Data Recovery & Diagnostics – Troubleshoot issues before they become mission failures.
- Software & Hardware Support – Train crew members, deploy new applications, and solve IT problems on the fly.
Where They Work
- Aboard submarines – Climate-controlled, high-security electronic spaces.
- Occasional shore assignments – Supporting IT operations at Navy facilities worldwide.
The Numbers
- About 600 ITSs in the Navy.
- Work in teams, but often take on solo projects.
On a sub, there’s no IT help desk—just you. If the network goes down, you fix it. If data is compromised, you secure it. Failure is not an option.
ITS Specialties: Two Paths, One Mission
The ITS rating is split into two specialized fields, each focused on keeping submarine networks and electronic systems operational.
ITS-COMMS (Communications Specialist)
The link between the sub and the world.
- Operate & Maintain Submarine Communication Systems – Keep secure comms running 24/7.
- Manage Databases & LANs – Oversee networks critical to mission success.
- Handle Cryptographic Material – Secure and protect classified data at sea.
- Test & Repair Communication Equipment – Fix problems before they impact operations.
- Support the Communications Officer – Assist in mission-critical communications.
- Serve as Instructors & Support Staff – Train the next generation of ITS-COMMS personnel.
ITS-EW (Electronic Warfare Specialist)
Defend, disrupt, and dominate the electronic battlespace.
- Operate & Maintain Advanced Electronic Systems – Work with cutting-edge submarine technology.
- Manage Databases, LANs & Electronic Warfare Equipment – Keep classified networks secure.
- Monitor & Repair Command, Control, Computer & Intelligence (C4I) Systems – Ensure mission-critical hardware and software function flawlessly.
- Utilize Fiber Optics, Digital, Microwave & Satellite Tech – Support secure information transfer.
- Diagnose & Restore Automated Information Systems – Apply high-level troubleshooting skills.
- Monitor Security Protocols & System Capabilities – Advise on vulnerabilities and implement protection measures.
