ITR is the communications service rating that came out of the submarine IT realignment. NAVADMIN 257/23 split the Information Systems Technician, Submarines (ITS) rating into three tracks. Network (ITN), Electronic Warfare (ITE), and Communications (ITR). The Navy's occupational standards list the rating as Information Systems Technicians, Submarines, Communications (ITR). The first ITR advancement exams ran in September 2024 (Cycle 264) for E-5/E-6 active duty, with E-7 boards following in January 2025. If you held ITS before the split, your communications work now lives under the ITR rating.
As an ITR you run the radio room. You operate and maintain the radio frequency, satellite communications, and cryptographic equipment a submarine uses to stay connected while submerged or surfaced. That means SATCOM terminals and antenna systems, HF/VHF/UHF transmission gear, baseband and circuit patching, message handling and traffic management, and the COMSEC accounting that keeps keyed material accountable. You stand communications watches where a dropped circuit is not an inconvenience, it is a mission failure, so you troubleshoot RF and transmission faults under real time pressure.
The training pipeline runs through IT "A" School followed by submarine communications "C" School, where you specialize in the radio, SATCOM, and crypto systems specific to the platform. Sea duty puts you on fast attack or ballistic missile submarines, with shore rotations at communications stations and squadron support commands. Most ITRs hold a Top Secret/SCI clearance because of the cryptographic and message traffic they handle.
Civilian employers value this background because it is rare. Plenty of people can configure a router. Far fewer understand RF link budgets, antenna alignment, satellite modem provisioning, and encryption key management at the level a submarine radioman lives in every day. That combination of transmission systems, secure communications, and disciplined operations under pressure is exactly what satellite operators, defense electronics firms, and secure-network vendors are short on. Related Navy paths worth comparing are the broader Information Systems Technician (IT) rating and the submarine-wide Information Systems Technician (Submarines) rating. To see how your rating maps to civilian work, start with the military to civilian career crosswalk, and if you want the resume framing first, read how to translate military experience to a civilian resume.
After my Navy time I pivoted into tech sales, and ITR is one of the most underrated backgrounds for that move. You already understand RF, SATCOM, and secure-comms systems at a depth most sales engineers never reach, and that technical credibility is what opens doors at companies selling network gear, secure communications, and SATCOM services. Customers trust the person who has actually run the radio room over the rep reading a spec sheet. — Brad Tachi, Navy Diver veteran & BMR founder
