FMFCS has 'planned' its way out of maintaining the fleet.
The amount of billed hours to get a single job done is huge. The process of planning the jobs, then assigning it to a shop...and then tasking the other shop...and then back to the first...crazy.
Consider, we have to install a new cable. We also need to install a cable bracket to hold it as it goes down a bulkhead.
The job is 'planned' into a work period, and FMF agrees that they'll do it.
First shops shows up and peels away the bulkhead insulation so that the steel is exposed.
Welding shop shows up, with a fire sentry, grinds off a spot of paint, and welds on a threaded stud.
Fire sentry stays for 60 minutes to ensure cooling/no fires/etc.
Next day, paint shop shows up, puts on a layer of primer (2 brush strokes)
Next day, paint shop shows up, puts on a coat of white paint over the primer (3 brush strokes)
Day after that, once the paint is dry, the insulation guys come back and re-install the insulation.
Paint shop comes back late that day to paint over the patch-tape for the insulation.
Day after that, the electrical shop shows up and threads on the bracket and starts the cable run.
Once the cable run is done, and is clamped in place on the bracket, the electronics shop shows up to do the cable termination.
Once the cable is terminated, they send another guy down to put a label on the cable. At each end, and on each side of every bulk-head penetration so it can be traced through compartments on the ship.
Then the electronics shop shows up again and tests the cable (can't test it until the labels are on) at which point it's ready to connect.
The Nav shop then shows up and connects the cable to the piece of nav gear that was just installed.
Then, once that's all done, the ship can, at the end of the work period, go back to the ammo depot and bring all the ammo back onboard that had to be landed so that they could weld that close to the magazine (less than 2 meters.)
OR,
Hire an ISSC, who sends a team of 3 guys over, and it's done in a day, and the planned cable run that would have taken it within 2 meters of a magazine is re-routed with an amendment submitted to the specification.
But....FMF is an efficient tool to maintain the fleet....
