Communication Network Technician Nuclear Submariner
As a Communication Network Technician Nuclear Submariner, you'll help write a new chapter in Navy history by making a meaningful contribution to the deployment of Australia's first conventionally-armed, nuclear-powered submarines. At any given moment, hundreds of complex networked computer systems are operating in tandem to keep our submarines operating at their best. When a network goes down, vital information may be lost, from global satellite data to special intelligence communications. That's why it's critical that trained Communication Network Technician Nuclear Submariner are on board to ensure networks and related systems are configured and operated properly, and errors are fixed without interruption to the mission.
What you'll do
You’ll be responsible for the effective management of the submarine’s communications and networked capabilities and providing expert operational support to command. Your duties will include the operation, routine care, repair, management, and maintenance of the complex electronic and communications equipment onboard. On any given day, you could be analysing, configuring, testing, or evaluating networks and other data driven systems. Ashore, you may apply your skills to roles in advanced network operations, administration, maintenance, and training.
Your duties may include:
- maintaining and operating radios, network modelling, analysis and planning
- researching and providing recommendations on network and data communications hardware and software solutions
- managing secure materiel and access controls
- acting as a lookout at sea while your submarine is on the surface or sentry when in port.
As a submariner, you'll also perform additional general duties that support the whole submarine, including:
- submarine security, firefighting and first aid
- assisting with medical, ammunitioning or ceremonial duties
- shift work, or on-call duties as required
- emergency response (damage control).
Opportunities for progression and upskilling continue throughout your career. As you progress, the Navy will provide you with development opportunities to assist you with your increasing leadership responsibility, as well as further education and specialised training within your chosen role. This will set you up to run a highly skilled team of sailors in a variety of tasks, both at sea and ashore.
Following initial military training in Australia, you’ll move to the United States to complete Basic Enlisted Submarine School and then ‘A’ School, both of which are located in Groton, Connecticut. Sea postings may be on submarines operating out of Western Australia, Hawaii, Guam, Connecticut and San Diego, and shore postings will be in both Australia and the United States.
