Mission Contribution
ITNs ensure the operational readiness of submarine communication and network systems, directly supporting secure and effective undersea missions.
Technology and Equipment
ITNs work with state-of-the-art information systems technology, including local and wide area networks, mainframe, mini and microcomputer systems, and associated peripheral devices.
They also operate and coordinate telecommunications systems, including automated networks and the full spectrum of data links and circuits.
Work Environment
Setting and Schedule
ITNs in the Navy Reserve operate primarily in secure, enclosed environments aboard submarines or onshore commands.
They work in small, highly secure compartments equipped with advanced computer and network systems.
Typical schedules include irregular shifts, rotating watches, and extended duty cycles during submarine deployments.
When ashore, schedules align more with traditional workweeks, but mobilizations may alter this.
Leadership and Communication
The chain of command is hierarchical and mission-focused, headed by senior enlisted leaders and submarine officers.
ITNs report to a Chief Petty Officer or directly to a division officer aboard submarines.
Communication flows through formal reporting structures, including operational briefings and secured digital communication.
Performance feedback is given routinely through counseling sessions and formal evaluations, typically conducted semiannually.
Team Dynamics and Autonomy
Submarine operations demand tight-knit teamwork under high-stress conditions.
ITNs frequently collaborate with other submarine ratings, such as Sonar Technicians and Fire Control Technicians.
Despite team integration, ITNs hold significant autonomy managing networks and cybersecurity tasks during operations.
They make rapid decisions to counter network vulnerabilities or communication failures.
Job Satisfaction and Retention
Retention rates for Navy Reserve ITNs are moderate to high, driven by technical career paths and advancement potential.
Success is measured by system uptime, mission-readiness reports, and successful cybersecurity defense.
Current service members report high satisfaction linked to specialized skills acquisition and mission-critical responsibilities.
Training and Skill Development
Initial Training
All Navy Reserve ITNs complete initial training through Navy Recruit Training Command and specialized “A” School.
Training Pipeline
| Training Stage | Description | Duration |
|---|---|---|
| Recruit Training (Boot Camp) | Basic military training in physical fitness, seamanship, and Navy customs | 9 weeks |
| Information Systems Technician “A” School | Technical instruction on network administration, computer systems, and cybersecurity | 24 weeks |
| Submarine Basic Enlisted School (SBES) | Submarine fundamentals, survival systems, and submarine-specific protocols | 4 weeks |
Advanced Training
ITNs can attend C schools and NEC-producing courses later in their career. These schools teach advanced system administration, network defense, and newer submarine technologies.
The Navy often encourages certifications such as CompTIA Security+ and CISSP. Many ITNs also build skills through drills, fleet exercises, and mobilization assignments.
Submarine IT changes fast, so training does not stop after initial school. Navy programs and some civilian-accredited courses support ongoing learning.
Physical Demands and Medical Evaluations
Physical Requirements
ITNs must meet Navy-wide Physical Readiness Test (PRT) standards and maintain them throughout service.
Daily duties aboard submarines are not physically strenuous but require endurance and alertness in confined spaces.
Tasks often involve standing for extended periods, moving through tight compartments, and managing equipment under stress.
Current Navy PRT Minimums
| Event | Male (17-19) | Female (17-19) |
|---|---|---|
| 1.5-mile run | 12:15 min | 14:15 min |
| Forearm planks | 1:20 min | 1:20 min |
| Push-ups | 42 | 19 |
Daily Physical Demands
Submarine ITNs endure prolonged seated or standing positions while monitoring systems and responding to network issues.
Equipment maintenance may require crawling into compact electronic spaces or lifting components weighing up to 45 pounds.
Stress management is critical due to the isolated submarine environment.
Medical Evaluations
Candidates must pass a Submarine Duty physical, ensuring fitness for undersea environments. This includes pressure-related screenings and audiometric testing. Periodic reevaluations are conducted to ensure continued submarine fitness.
Annual medical checks assess overall health, hearing, and cardiovascular endurance.
Deployment and Duty Stations
Deployment Details
Navy Reserve ITNs face moderate deployment likelihood. Mobilizations can range from several months to a year, depending on operational needs.
Deployments primarily occur aboard submarines operating in both domestic and international waters. ITNs may also deploy to shore commands supporting submarine operations or cybersecurity missions.

Risk, Safety, and Legal Considerations
Job Hazards
ITNs aboard submarines operate under high-risk conditions. Submerged environments create hazards such as restricted movement, limited escape routes, and prolonged confinement.
Electrical hazards exist while servicing network systems and power-driven equipment. Cyber operations introduce mental strain during sustained high-threat network defense scenarios. Extended isolation and continuous system monitoring increase physical and psychological demands.
Safety Protocols
Navy submarine protocols mitigate these risks through enforced procedures. ITNs complete mandatory safety training, including confined space entry and electrical safety.
Daily checks and system inspections ensure equipment integrity. The crew conducts regular emergency drills, including fire response, flooding control, and casualty procedures.
Cybersecurity teams follow strict incident response protocols to secure systems during attacks or failures.
Security and Legal Requirements
All ITNs must obtain and maintain at least a Secret clearance. Some billets, including cyber defense and submarine communication roles, require Top Secret eligibility.
The clearance process involves security interviews, background investigations, and periodic reinvestigations. ITNs are subject to the UCMJ and reserve contract terms, including mandatory drill attendance and mobilization readiness.
Deployment in Conflict Zones
ITNs may deploy to areas supporting conflict zone operations. Submarine missions often involve high-stakes intelligence and surveillance near contested regions.
Mobilizations follow operational orders and lawful directives. During emergencies or rising tensions, ITNs may face extended deployments under heightened security and force protection postures.
Impact on Family and Personal Life
Family Considerations
Navy Reserve ITNs must balance service demands with personal responsibilities. Drill weekends, annual training, and mobilizations require time away from home.
Submarine deployments add extended separations, often with limited communication. Families must adapt to unpredictable schedules and possible short-notice mobilizations.
Support is available through Navy Reserve Family Readiness programs, counseling services, and command ombudsmen.
Relocation and Flexibility
Reserve ITNs typically serve near their home region. However, mobilization orders may require relocation to active duty stations or deployment staging areas.
Relocation is temporary but may last months. Flexibility is essential for rapid assignment changes, mission requirements, or specialized training.
Family support services assist with transitions during relocations and extended duty periods.
Post-Service Opportunities
Transition to Civilian Life
ITNs transition into civilian careers using submarine-acquired technical skills. Common post-service opportunities include:
- Network administration – Focused on maintaining and securing enterprise networks.
- Cybersecurity roles – Positions in threat detection, network defense, and incident response.
- Information systems management – Overseeing IT teams, projects, and systems architecture.
- Defense contracting – Supporting classified government or military systems with advanced IT skills.
- Federal employment – Roles in agencies requiring technical expertise and security clearance.
Support programs include:
- Navy COOL – Provides credentialing for certifications like Security+ and CISSP.
- DoW SkillBridge – Facilitates internships with civilian employers before separation.
- Transition Assistance Program (TAP) – Offers resume workshops, interview preparation, and job placement resources.
