This can vary, but for most submariners it's the time they look forward to the most. You could be alongside various ports within Australia or overseas for some time, or if your submarine is on a training cycle you might go to sea in the week and be back home for weekends. On the other hand, if your submarine deploys overseas, your time at sea can vary.

It averages out at roughly 17 weeks at sea per year with individual deployments ranging from eight weeks to six months, including port visits. This is similar to the time spent at sea on ships. For a closer look at life on board, watch life on deck with submariner Jess.
