MMS question

[Jnewman16]

I've enlisted in Machinist Mate Submarine. (conventional). My question is simple. After Submarine school, do you go straight into either the weapons or auxillary training, or is their a MM A school followed by either weapons or auxillary. I've read different things. Brother is deployed so i cant ask him :(

As a Machinist Mate you are a mechanic, you probably will go to A school for that rate, either before or after sub school. Might be after your A school since if you fail sub school you will be just sent to fleet to any other ship needing a MM. Just for info, my son said that MM's on the ship he was on worked right along side the MM(nukes) just didnt get nuke pay or perks.

You'll go to MM A school and then to sub school. If you don't make it through sub school, you'll just go to a ship as an MM. You will work along side the nukes, but you can't work on certain things they can that deal directly with the reactor plant itself and you stand different watches then the nukes (theirs deal with the reactor, yours would be related to more secondary systems).

I understand that... I was told from my recruiters that i'll go to sub school immediately following bootcamp.. during Sub school they will designate you either weapons or axillary.. Would your axillary or weapons training be considered C schools. My brother is a nuke MM so he has told me all about a-gang.. lol

I asked my son about MM's working on weapons, he said he never heard of that nor had he ever met one that did, not saying he was wrong, just never met one. But here is the official MM rating info discription:


Machinist’s Mates (MM)
operate and maintain steam
turbines and reduction gears used for ship propulsion
and auxiliary machinery such as turbogenerators, pumps
and oil purifiers. They also maintain auxiliary machinery
outside of main machinery spaces, such as electrohydraulic
steering engines and elevators, refrigeration plants,
air conditioning systems and desalinization plants. They
may also operate and maintain compressed gas producing
plants.

What They Do
The duties performed by MMs include:
•

Aligning piping systems for oil, water, air and steam,
and controlling the operation of ship boilers and
steam turbines used for ship propulsion and service
systems
•

Controlling operation of turbogenerators used to
produce electrical power
•

Cleaning, adjusting, testing and performing other
preventive maintenance on a ship’s boilers, main
engines, turbogenerators and other auxiliary machinery
including steering engines, elevators, winches,
pumps and associated valves
•

Operating and maintaining desalinization plants
(distilling plants) to make fresh water from sea water
•

Maintaining refrigeration plants, air conditioning
systems and galley equipment
•

Repairing or replacing valves, pumps, heat exchangers,
compressors, steam turbines and hydraulic or
pneumatic control devices
•

Making entries in and analyzing machinery operating
records and reports

Basically as my son puts it, MM's and even nuke MM's are plumbers with REALLY big wrenches!

they merged torpedoman with MM rating on the submarines.. your either a MM-Wep, or a MM-Aux.. i talked to my leading recruiter today and he again told me that i'll go to submarine school following bootcamp.. then go onto whatever training (wep or aux) they the navy puts me in.


The MM-AUX is a Machinist Mate (MM), assigned aboard a Navy submarine, who specializes in maintenance and repair of auxilary equipment. MM-AUX are specialists that work to maintain and operate the different submarine mechanical systems, and non-nuclear related operations systems in air, refrigeration, hydraulic, atmosphere control, diesel and plumbing systems. You cannot get a guarantee for this rating. You can volunteer to become a Submarine Machinist Mate, and you are assigned to either MM-AUX or MM-WEP (Machinist Mate for submarine weapons) during the training pipeline.
