OM Submariner is an Opperator Maintainer and basically you use the kit and repair/service it - usally in the sonar room - you become the ears and eyes of the ship but are also a electrical engineer of sorts...
my bezzy oppo is an OM and is now a Petty Officer, he said its a fantastic job.
who knows man - i did notice they change more often than the tides... and notice trades drop off the website and others appear - an oppo is the recruiting Chief at Derby RN Careers office and said they only advertise needed branches and trades. (which makes sense).
also heard with the new carriers - a trade will be ressurected from the dead to cope with conventional carrier landings.... the arrestor wire folk.
dont look at me - i am a cook/steward instructor. warmer still.
recently had the pleasure of a over night voyage on HMS Grafton and i was asked if i could help out in the Galley as the PO Chef was on paternity leave, so i took my whites and cooked all the tiddly food for the ward room.
hadnt noticed we were at sea until 2 hours later and i saw the water in the sink all wobbly.
Got to be a little careful with Subs at the moment. The Sub Pay is still there, but the LSSB has changed - it will only apply when you are deployed, not as "off crew", or time alongside. I understand that this impacts quite seriously on their pay packets. In addition, watch for the anti-smoking legislation coming in regarding subs.
Best bet is to get to a careers office, pick up the brochures, and have a good look through them. Go back to the careers office and ask to talk through the options with the careers advisor. Which is your nearest careers office?
The submarine service has its benefits and disadvantages. Don't expect to see much of the world, and the duty rosters for subs alongside can be challenging , depending on what branch you are in. The extra pay is still there, but I've always prefered to see daylight from time to time. The medical standards for entry into the sub service are stringent, so there is no guarantee that you'll be accepted into it even if you get through the gates at Raleigh. You can join, go to sea as a skimmer, and then volunteer for subs.
Notwithstanding the above, the only source of advice you should take as gospel is the AFCIO, everything you read on sites such as this one is merely opinion
