Had a massive reply done here, then my computer crashed. FFFFUUUUU
Ty for the reply Ace, appreaciate it. Here is my massive reply:
1.you have an 230m long trimaran, so I suppose the beam would be at least 60-70 meters. keep in mind that that is about the size of an aircraft carrier..... you will have to be able to dock that.
Whenever I'm going to check the interior to see if everything fits, I'll see by how much I can shorten it. It was not my intention to have it that wide, I was planning something more along the 40 meters.
an weird thing I see is the fact that the ship has not wave piercing bow on the main hull, but it has some sort of on the outriggers. I myself would expect it the other way around..... and I would like most if both had an 'regular' bow
Will fix it. It wasn't my intention to have a wave piercer. I hate those things.
I'd like to hear the reason you chose an trimaran design. right now it looks like it is just so you can have an larger hangar and that large mast, as the internal space does not increase that much. maybe consider an 'pentamaran'
I have considered multiple hull forms for this. To do so, I formed a list in my head with the advantages and disadvantages of all the options I had, and then I figured out what disadvantages I can live with. Here is that list (notice it may not be entirely accurate):
Monohull
+Proven concept
+Low cost
+Decent internal space
+Guys at SB won't hate it
(JK)
-Really boring (JK too, but you can't argue with rule of cool)
-No real disadvantages, but no considerable advantages either.
Catamaran
+High speed
+Good stability
+Plenty of deck space
-Virtually no below deck space
-Requires an unconventional layout
-Needs to be very tall to fit strike-length VLS
-A couple more things but these two above really made catamaran useless for this application
SWATH
+Same as catamaran
+Very high speed
-
All the bloody disadvantages of a catamaran
-And a very deep draught, which makes littoral situations a no-go
Trimaran
+High speed, just like catamaran
+Good stability, same
+Plenty of deck space
+Unlike catamaran has a bit of below deck space (not that much more, but good enough), can use a conventional layout
+Can operate in shallow waters
+Slightly better stealth performance? (Really a neglectable advantage)
-Large, especially in width
-Less below-deck space
-Less maneuvrebility (can be improved by retractable voith-schneider\azipod thrusters, as done on the LCS-2)
-Vunerable to structural damage (if one of the outriggers breaks off, bad news)
X-bow
Really a lot of advantages but it'd be difficult to plan out the gunnery and point defense on such a ship. Yet still I do sort of feel attracted to the X-bow, it came at a close second. Might make one of these later.
Tumblehome
+Better seaworthyness?
+Can go faster in high-sea states compared to others
+Can maneuvre through canals better (something trimarans absolutely can't, lol)
+Slightly better stealth performance
-Ugly hurr
-Supposedly unstable, especially in high sea states
-Can't make high-speed turns
All in all some say its supersuperstable, other say it's disastership Titanic II. It was definatly
not something I want in my navy, not for small nor large vessels of any kind
Pentamaran
This was also an interesting option but because of the lack of information on advantages and disadvantages - and on possible military uses - (and what's more; me not even knowing how such a hull looks on a side view) I forgot about it for now. But maybe I'll redo this in pentamaran form, since the outriggers of such a pentamaran make excellent CIWS\gunnery positions and because the internal space would allow a nuclear reactor to fit with no hassle.
Axe bow
Nah, I didn't even consider this one seriously. For no real reason tbh.
In the end, the trimaran's stability (which allowed me to have a taller mast, just like you guessed) was what convinced me to go for a trimaran. I may switch to pentamaran if I can get more information on it.
why not put the bridge more aft and a bit higher, moving the VLS in front of it, and the mast just aft of the bridge? right now you have an horrible line of sight, waves crashing into the bridge in storms.
I thought that with the bridge further forward the line of sight would be better, but I didn't took waves into comparison so I'll move the bridge back and VLS in front.
I am not an fan of hydrojets at all. nor the VSP, to be honest. and not the pod as well. I think conventional propulsion would be best here, azipod second, waterjets after that.... VSP just doesn't deliver you the speed you want.
With this ship being nuclear powered, the prime disadvantage of hydrojet propulsion disappears. That disadvantage is efficiency\fuel consumption. Since a nuclear reactor can run for years, fuel consumption is not something to take into account.
The azipods\VSP (not sure which one to choose yet) are secondary propulsion systems to be mounted further astern, and they serve for maneuvering only. Not as primary propulsion. Speed doesn't matter in this application; the waterjets provide that kind of speed.
I'd really like to know, even in words, what kind of underwater hull you want. other comments depend on that.
I'll be fairly honest in that I have no idea myself; and for that reason I didn't draw the underwater hull just yet.
some things look really stealth, some really don't XD
Lol, I see. What is there to improve?
that mission area deck gives only 1 problem: it is spread over several decks. you can store vehicles in helicopter space, but you cannot put an heli in the vehicle space. try to put the cargo deck all on 1 level, or separate the heli hangar from it.
Good idea, I'll work on it.
an trimaran hull is not the most spacious hull possible
True. I was sort of worried about this too. I tried compensating that with length, but soon I'll draw the inner spaces of this ship too.
nuke..... keep in mind that you need an entire infrastructure for nuclear powerplants, which you want to use as much as possible..... I doubt this is an large class so do you have other nuclear ships?
Yes. A guy on NS plans to release a nuclear powered AOR soon, which I might purchase, and aside from that I think I want my carriers and maybe my LPD\LHA to be nuclear powered.
you will be limited in the allied ports you can enter, especially with damage (when you want it the most)
That is true. But in NS I think I can overcome this.
you need an reload hatch for access to your reactor for refueling. you'll want the reactor around the center of gravity, not the mast.
Right now the reactor is exactly below the mast. So they're both at the gravity centre. How would such a hatch look like?
I completely miss ASW weapons
Forgot to add the torpedoes, my bad. Also, there's MILAS in the VLS.
you have at least 4 types of ammunition on board. 2 types of 12.7, 57mm, 127, and that huge honking gun on the bow (8'' or 155mm, I suppose?) possible, but logistical nightmare
I don't feel confident about that aft gun either so I'll probably remove it. Might replace it with a 57. (Btw, that's not the Bofors 57 there, it's a custom 60mm gun.) The gun on the bow is 8'' btw. Bigger is better, lol.
I am really not an fan of the CIWS setup. it blocks the APAR, gives some deck pen problems and limits the space on the bridge. also, I doubt if you need them: if you move the 57's more to the sides you have an adequate CIWS coverage, with maybe one additional 57 near the bow....... but if you change the bridge arrangement that isn't even needed.
I'll move around with it a bit (and attempt not to increase the height of the APAR, which was the first solution that popped up in my mind and probably the worst too). Anyways I do wish to keep the Goalkeeper II, I like it a lot.
you have at least 3 different companies making your weapons. again, logistical nightmare!
The FREMM uses equipment from Thales, OTO, and MBDA. That's also three companies, but it's not a logistical nightmare, is it? All the equipment I do use is NATO compatable so I guess it wouldn't matter too much.
I suppose your VLS is amidships. this gives an really weak point on an already weak point in the hull (the point were the bending moment is the largest) and possibly also gives you some trouble with the machinery space.
I'll move it to the foredeck. A shame, because I like the way it looks here.
aster doesn't work with APAR. ASTER is an active missile, APAR is for semi-active missiles.
I see. So what equipment do I need to guide Aster?
you see that huge piramid underneath the mast? that, and an large part of what's underneath is gonna be filled with the cooling systems and processing systems for the radars.
Indeed, that's the idea.
normally you want to have your targeting radar (APAR) higher then the search radar.
I used to have one with the APAR above the search radar... but ehm, it looked really bad; the mast was stupidely huge at the base. But I'll fiddle around with it again.
the FC on top is unnecesary, as the APAR is far more powerful
Will replace it with a SATCOM\EO camera
you are not going to get the SMART-L's range out of this, while it will be 4 times as heavy (not counting the cooling systems, those will most likely 10 times as heavy) you won't need that range though, as the role of this ship is not ABM and you get the additional power of 360 degrees 1000km + range.....
This ship may not be for air defence, but other ships equipped with this mast are. I'll attempt to put a real Smart-L on this, no idea what it will become but it's worth giving a shot.
the inside of that mast is gonna be cramped..... not good for maintenance.
Will make it larger.
you call this mast for AAW DDG's..... but it won't fit on any ship smaller then this!
Will make it smaller.
...
Wait wut?
No really. I don't know exactly how to fix all this, but I will find out one way or another. Even if it means I'll have to design the entire ship around the mast.
