Logi's Design Studies

[P3D]

The 400 troops is the short-distance one.

WWII APA needed about 10t displacement  per trooper. If you take Queen Mary, 16000 trooper was hot-bunking (sleeping in shifts) on the 80,000t ship (5t/trooper), for a few-days cross-Atlantic voyage at 30kts. And that's a troop transport, not an assault ship that needs to carry food and ammo for the troopers, and the holds being stowed for ease of unloading (which cuts efficiency to half or so).
1t misc weight for a trooper is right for a short-range (two nights at most) troop transport, 2t for an assault ship with landing boats/lighters or for long-distance troop transport (as in from France to India).

[Logi]

That is want I mean by short-range. I was told since the Asian population is of relatively small posture. As such, I would think you could probably fit more Chinese people in a APA than UK or US people. (Believe, I know. Chinese people are about 75% skinner than whites, blacks, etcs)

As such, I would thing such a ship could hold alot more people for short-range (no need to carry all that food). I myself only eat 2 meals a day and they are what one would consider reduced rations (1 bowl of rice & 1 small plate of side dish). I would think one would be able too carry more chinese troops than say CSA troops.


Now, if you believe it really cannot carry so many people, I will reduce it to:
300t (Standard)
500t (Short-distance)

It's not really about body height and diet. Ammo would take more up than food. Anyways, of you want the troops function to any standards, two bowls of rice won't cut it for heavy physical work.  But the largest volume is mules/horses and their fodder pulling the artillery and supply wagons.

And perhaps Tanthalas would tell us about the accommodations that the USN provides for the marines in ships. The USN is famous to cram 50% larger crews in similar sized hulls than the rest of the world.

Hmmm... Questionable but I'll let it slide.

But the largest volume is mules/horses and their fodder pulling the artillery and supply wagons.

Why would I need supply wagons? Please clarify. I intended to use such ships as an direct assault on port cities. Not much of a distance to travel there.

Maddox and Tan have said that it seems fine.

To transport 500 infantry with their gear over a reasonable distance, (not Hong kong to Singapore) yes. But as P3D writes, if you start to load draft animals and artillery, it becomes another matter.

well we got 3 square a day (4 if ya were up at midnight for midrats), birthing on USS Wasp we slept 60 to a birthing, each birthing Compartment had 3 shitters, 2 pissers, 7 sinks (one sinf with the pissers and shitters 6 in by the showers), and 6 showers.  The Majority of the ship was actualy given over to Storeage (Helos, LCACs, Equipment, Food, Amunition) im fairly sure you could do away with all the comand and control equipment (not like your planing to qordinate 2200 Marines landing on a beach) the aircraft Facilities would be unnecessary, but you still come down to needing to have a rack for each man and a place for him to stow his equipment (aswell as spares, aditional ammo, medical suplies) and if you want them to fight at the end of the trip you had better figure on feading them 3 meals a day, and providing an area for them to exersize (we ran laps around Wasps flight deck twice a day).

any other questions =P

@Maddox
It was meant to be used in Habour Assault. Only men charging into the city and destroying things is needed, other ships as well as the APA would provide artillery support. Also, as I stated to P3D, since it is an almost instant disbarkment - raiding, there is really no need for animals.

@Tan
Can't incorporate an area to excerise :( (Although they could run around the front and back of the ship when the guns are not in use).

Also, are you saying that such as it is, it does not provide enough food for the troops?

[Tanthalas]

for referance here is the ship im farmiliar with
http://en.wikipedia.org/wiki/USS_Wasp_(LHD-1)

Each Marine had a Rack (bed) they were stacked either 3 or 4 high (depended on which birthing compartment you were asighnd to) each rack is 3' X 7' X 8" (the 8" is important because you are expected to stow all your uniform items in the locker that is part of your rack).

 Also there was a Marine Armory onboard where your Rifle and personal load of Amunition were stowed.  

this is a Mess Decks (on a CV i think as there are alot of colord shirt guys which are plane handalers)

I realy dont know much about the operation of the ship, my life during trips was fairly boring.

*gasp* Such space on the Mess Decks. The beds are pretty cramped though.

In some schools the kids are literally squeezing each other into sandwiches. One I used to go to had about 3000 kids in a caferia at a time in a fairly small area. It became a oven during the summer.

figure that mess decks is proly rated at 1000 swinging dicks an hour

the racks are damn tight, big guys cant turn over once they get in em (im only 6' 225 and I couldnt)

Please note this quote from the Ship Design Guidelines in the Rules:

Troops:  1 t per four troops for short-ranged landing craft.  2 t per troop for long-term (> 1 day) embarkment.

[Logi]

PLAY THE GAME, NOT THE RULES

:D

So following the rules, it becomes 250 troops for long distance travel and 2000 for short distance.

[P3D]

Where do you get that 2000t misc weight? Bunker capacity cannot really be converted into additional accomodations.

The ship with its all forward aimed armament reminds me a little bit of the Go Ni Mk.II I created for Wesworld. Guns forward to blast any idiot on the beach to bits. It's slightly bigger than the Jap-Gig and has limited armor to protect the crew but I was always a little bit worried about its draught. The Mk.I was about 2/3 and the Mk.III about twice the displacement of the Jap-Gig.

I used 1.5 tons to calculate the number of troops for those ships since the Japanese soldiers are lighter and smaller so it was good for 330 soldiers (250 regular-sized soldiers)... and it ain't no luxury ocean liner.

Firing arcs were never a big issue of the ship as I expected the main firing zone to be 30 degrees either side.

No lightweight fiberglass in this age.

How about plywood? :)

Sounds like a 17th century slaveship to me actualy

Yes, it is. The 2 tons/soldier is also a matter of volume, not just weight of the soldier and gear and support facilities.
