I see it's Canadian. Perhaps Kevin designed it and if so they shouldn't have too much trouble!!

I recall reading about the mechanical sighting computers aboard the Iowa class Battleships in WW2. It was said that those "Mechanical" computers(not digital) are so advanced that no modern computer could effect any improvement in the fall of shot. You can imagine how ROBUST a mechanical computer is. Thats what we need.

Mk 48 going in the Georgia inverted. How do they do that?

Turn it on its end is how. Obviously there is a large enough torpedo room to turn it to the horizontal once embarked.
As for the gunnery computers in the Iowa class battleships, they weren't computers but predictors. They reliably predicted where the target would be when course and speed of both ships were inputted.
The Royal Artillery Lt AD Regts had mechanical predictors slaved to aircraft sighting radars and reliably predicted where to aim the gun, up to a target speed of 500knts. Trouble was that as aircraft got faster they hade to modernise and the result is Rapier which is now all weather and there aint any aircraft in a ground attack role that can escape it when it locks on and the operator can see the target as he can control it in flight. The Gunners, aka 19 mile snipers, would say, "If we can see it we can hit it" The sods always did.

Yes, they must have a cavernous torp room but even more a hatch large enough to allow the tail end to pivot which takes up considerably more room than would the diameter of the torp itself, unless its deep enough to completely turn below decks. I was surprised to see this when most of the time you see them going in at an angle.
As to the Rapier, they must have some kinda sighting device If they can see it 19 miles away, or is it a radar blip?

Regarding to RAPIER, there's a BBC program about Malvinas (Falklands) war where you can see how RAPIER batteries rub out the sky argentinian planes. Really impressive.

There, thats a little better:

The Rapier Battery is connected to AWR and the actual sight is optical and the operator follows the target by using a joystick to track the target and when locked on presses the tit to launch the missile.
19 mile snipers is the nickname the Gunners use in the British Army. They have guns that can range out to 19 miles and can acquire targets from Phoenix which is an unmanned drone which sends back real time tv images and a grid reference as to where the target is. Input the data, load the gun, press the tit and bingo, one shell on target bye bye bad person. Simples.

So thats where being good at video games can be helpful.

The "mechanicle" or analog computer used for WWII fire controll systems was basiclly a big slide rule for the Trig problem of sending a balistic projectile down range to target, with more percission than iron sighting. Hence the term "Firing solution" The FC system on the battleships were huge, since they had to service several batteries, the 16" mounts the 5'x38 mounts and the 6"x50s. The antiaircraft weapons had their own seperate FC. The fleet subs had basiclly the same calculator, the TDC (what you yunguns call computers) but were downsized to facilitate close quarters. My youngest son is a Fire Controlman aboard a Ticonderoga class cruiser. His primary job is targeting the missiles, but he is a Navy sniper as well. The firing data computers he uses in both jobs are similar. The one in CIC is a standard computer station, the one used with the rifle, out is pocket size. The advances that have come along in artilliry targeting in the past 10 years have jumpped leaps and bounds. Its no longer just point and shoot and hope your math is good. With the advent of laser targeting and smart weapons you dont even have to aim in the direction you want the projectile to go. A remote targeting device such as a Preditor or a SOCOM Operator with a pointer, or hand launched model R/C mini plane or helo, paints the target with a dot, and the kid that fires the weapon could be in the middle of the ocean 1000 miles away. The kid that is actually flying the remote over the target could be in a room in Idaho, or the operator that launched the viehicle with a hand held joy stick. That thing about kids and computer games is dead on. In Dahlgrin Va the Navy has a weapons school, and they screene recruits that are exceptional in vidio gaming. About 80% of the training thruout the navy today is simulators, be it aircraft, tanks ships missiles or even boots on the ground shooter games. Mabe in the future kids could do their military duty at home, and we just send the machines of distruction to the bad guys. As for the Mk48 going in the Georgia, its 21" dia and about 20ft long. The Georgia is huge compaired to the old boats. Its 40 ft from kiel to deck, and 40 ft wide. The torpedo room is big. you could u turn a Kia in there boys.I posted some stuff about our RMMV testing awhile back, you must have missed it. Heres one down at NSWC key west, with my friend Ted, who is site mgr here. He is an avid R/C airplane buff on the weekends. It must be tuff having a job playing with multi million dollar r/c subs all day, so ya gotta relax on your timeoff

Cavernous yes I suppose. In the RN boats the torpedo room has a removable deckhead of pierced aluminium planking that is lifted to facilitate torpedo loading so there is plenty of room to swivel the thing through 90º to the horizontal for stowing.
