Japanese Ship Designs 1912+

[Desertfox]

How is this? Dropped all the armament. It is now officially a "rescue ship" and will be painted as such, balloon is to "spot sailors in water". In a battle situation it would be used as a rescue ship, but that would be its secondary role. It would also have a tertiary role of dispatch ship.

Are Observation Balloons considered outside the Aircraft/Seaplane Carrier Architecture tree?

[Kaiser Kirk]

I said this:

C) I'll say up front - a design ruled non mercantile can not be redeemed by small changes. intent of a design is to produce a cheap warship has been established.

I wanted to be clear that small changes were not sufficient.
I didn't want to play the "made minor alteration, is that enough" game over and over.

You noted it and needed clarification.
I provided that.

So you said this:

How is this? Dropped all the armament. It is now officially a "rescue ship" and will be painted as such, balloon is to "spot sailors in water". In a battle situation it would be used as a rescue ship, but that would be its secondary role. It would also have a tertiary role of dispatch ship.

Basically, you unbolted 16 tons on deck. Replaced it with on-deck equipment.
Replaced fire control with a "experimental radar"....
oh and change the rationale from Scout to Rescue.

Do you want to take a guess as to the answer?
I made my statement for exactly that reason.

I'm actually a little insulted.
It's the same darn hull and machinery, all you did was change your explanation and unbolt some things.
You can turn around and bolt them right back on with a basic refit.
What type of shenanigans is that?
This type of thing frustrates ME and YOU.

YOU can have exactly the ship you want. Just pay full price

You want to a way to pay 1/4 price: Then at this point I would suggest that you build yourself something that looks like a nice bulky slow merchant hull and slap the same armament on it, tow your balloon with that.

9.35 LB, 0.490BC, 24knots, is a destroyer hull with a smaller engine.
It's not going to cut it.
At this point, I think there should be a clean break and a clearly different design.
Try something like this : <6.5:1 and 18knots, <=2% armament.

A fast transport capable of landing troops without port facilities.

The degree you need a port is governed by your tech level, not your ship design. The higher your amphibious tech, the less dependent you are.
The key stage is getting to the x-lighters and designed troop transports. Those will magically appear among your deployment point.
However I will strongly stress that landing rates and amount of supply at a port facility will exceed that of over the beach until you get to Mulberry harbors.
Even then, they will have limited capacity.

So folks are free to design transports.
There is some utility, such as the Japanese landings on Korean islands, which will be taken into consideration.

Spy ship, disguised as a schooner. Hidden gun for self-defense can be replaced by twin 14" torpedo tubes.

I really do think we should reconsider allowing petrol engines for certain ship types. For this ship the engine is mostly a backup and at under 600hp similar in size to sub engines of the time period

Snip's specific design goal was simplicity.  Strip out the more complicated elements. Don't endlessly specify.
The result is still complex, but much less so.
Adding furhter complexity back in for minor uses is unlikely and will be done on the basis of pressing needs.
As such petrol engines is unlikely. Diesel engines, much safer, are on the horizon.

Are Observation Balloons considered outside the Aircraft/Seaplane Carrier Architecture tree?

That's a bit of what I was struggling with earlier.
Trying to figure out where this slippery slope of interpretation goes.

But Aircraft/Seaplanes are not Balloons.
Balloons are are covered under Aircraft baseline.

I know there were tethered Zeppelin experiments which were not a great success.
But Hot air balloons are collapsible.
Obviously it couldn't be towed at speed, the pitch/yaw going through waves would whip the cable and likely destroy the balloon or break the cable.
But in fair weather, as an observation platform... I could see use.

So at this point I plan to stick to the wording of the techs and let the experimentation go forward.

[Desertfox]

I'm sorry, but I don't understand what the problem is, are we just NOT allowed to build fast auxiliaries? Because, those did exist in OTL, some of them (and even civilian banana boats) even used actual destroyer hulls. Ocean liners were consistently faster than warships and even the first MTBs started life as civilian speed boats.

Rescue ships are well established auxiliaries that where usually based on DE hulls and I just had a convoy get half sunk and had to stop actual warships to conduct rescue operations. And the reason I went that way was it was a legitimate IC way of not having it get caught and sunk like the Ujis did or how a slow 18 knot armed freighter would. Is it IC shenanigans? Yes they are, I'm not trying to hide that. But OOC, I took the guns off because they are detrimental to the ships goal. I have zero intentions on arming this ship, if you want to slap a mod ban on rearming this ship during a refit, I'd be perfectly fine with that. The whole point of calling it a "rescue ship" is so it doesn't need weapons. Could it be refitted into a pseudo-destroyer, probably, but it would cost almost the same as a new-built one for half the capability. Now that would be a waste of resources.

As for radar, that was on the original design. The only Japanese ships with radar are auxiliaries, since at this time it is still very much unproven technology. So its better to test it on an auxiliary than on a front-line combat ship that needs every ton accounted for, same as the Parthians testing turbo-electric drives on the Whales.

[Jefgte]

About Kaibokan.
It is clearly a ship to light the fleet with a 24kts speed, a balloon, and rescue boats (after the battle).
He is a wing auxiliary which plays the role of scout cruiser.

[Kaiser Kirk]

Topic 1.

I'm sorry, but I don't understand what the problem is, are we just NOT allowed to build fast auxiliaries? Because, those did exist in OTL, some of them (and even civilian banana boats) even used actual destroyer hulls. Ocean liners were consistently faster than warships and even the first MTBs started life as civilian speed boats.

Using the Auxiliary rule is not automatic. As the rule states, it is explicitly subject to review.
If it seems like the type of vessel that can be a cheap warship - or easily refitted to that, or able to work replace one in some role-then it will be at risk of being disallowed as an auxiliary.

The reason that clause in the Auxiliaries is there is to keep a strong barrier against blurring that line and allowing cheap warships.

That is a deliberate game design choice.

That means some vessels that were historically built as mercantile construction - sloops/corvettes/destroyer escorts/escort carriers...are not mercantile or commercial construction here.

You can build them, you do not get a discount to build them.

It's almost like a Flower-class corvette on a slightly larger scale, which is a ship historically built to commercial standards.

He is a wing auxiliary which plays the role of scout cruiser.

Im going to ask for a judgement under the last provision of the Aux rules, as this feels like a cheep warship to me.

You want a liner that goes 24knots and displaces 20,000 tons... keep the weapons and armor under 2% and we'll talk.
That's a fast Auxiliary.

A 150ton trawler could tow the 10 ton balloon at 16knots. That would be a mercantile build.

You want something that looks like an escort, has a large chunk of displacement in it's top of the line engines with a tiny bit of Misc weight dedicated to other things?  No

Topic 2

Rescue Ships
The problem here is you presented the design one way.  It was ruled warship-like and disallowed.
You were specifically told minor changes would not be sufficient.

You unbolted some guns, bolted on some compensating weight, renamed it and presented it again.

Since those certainly count as minor changes. It is still ruled warship-like.

Topic 3

The Auxiliaries in N7 almost did not exist.
As I recall, Snip (sorry if I get this wrong) wanted to delete the category and handwave all that in the name of KISS.
I thought there was an important role for if a nation had invested in a fleet train, colliers, oilers, amphibious ships.
Snip shot down most of that, but saw the value of the fleet train...in a very simple form. So we have the Fleet Supply.
And he tried to ensure that they would not be a way for folks to make cheap warships.... wether upfront, or by later conversion.

Topic 4.

Are Observation Balloons considered outside the Aircraft/Seaplane Carrier Architecture tree?

My first response was basically a hot air balloon is not..the same.. as an Aircraft as it has no motor or skeleton.  Not I did not say wings or self powered flight.  So Zeppelins, Gyrocopters, etc still are aircraft.

Aircraft and Seaplanes it obviously is not, so Aircraft/Seaplane technology would not apply.

Today I was reconsidering my prior answer.

A Balloon is a big floaty gas bag...that's a craft...that goes in the air...

It actually appears as a baseline technology...under Aircraft.

Which would make the balloon an aircraft.
Therefore something carrying it, readying it for action, deploying it, recovering it, etc. .an aircraft carrier...
I think that's what Snip was getting at.

I just have problems with that interpretation, it seems so far from airplane operations.
The skills and training needed to launch and recover the balloon are extremely different than flying planes on/off ships, or recovering them from water.

So I'm inclined to say hot air balloons, while covered under Aircraft tech, do not need the specialized aircraft handling skills one associates with carrier ops and so do not fall under aircraft carriers.

I'm willing to be told I'm wrong.

Topic last

Parthians testing turbo-electric drives on the Whales.

The irony here is the build schedule on those has gone so over time, that most of the electric drive knowledge is coming from the Parthian Minesweepers.
Which I found aren't in a minelaying category.  I should make one and move them, as I pay full price for the MSWs.

[Desertfox]

If the biggest issue is, the potential for future conversions, why not add a simple addendum to the rules? "Ships build to mercantile standards, can not increase the percentage of weight dedicated to weapons/armor during a refit/refurb". It would ban, merchant ship conversions into AMCs, but it sounds that that was the intent of the rule in the first place, even if some fleet support ships already qualify as AMCs.

25t - Minesweeping gear

[snip]

Im not sure we have ever covered batteries as a engine type. I'm opposed to them being a checkbox-only option, but would like to find a way to include them.

[Desertfox]

I thought that's how turbo-electric drives where supposed to be?

Updated drawings of the Kaibokan and minesweepers, plus the junk spy ship:

[snip]

You did the Electric Drives part right, Im talking about the addition of batteries into the Engine Type field.

[Desertfox]

Well it turns out that adding batteries decreases engine weight by about 25%, that is weird...

[TacCovert4]

Well it turns out that adding batteries decreases engine weight by about 25%, that is weird...

I suspect that the batteries in this instance are being considered as a booster rather than a stand alone method.

The turbines are probably cruising speed plus some capacity.   In normal operating conditions they charge the batteries.   When the ship goes ahead flank, the batteries are fed into the power supply to boost amperage for maximum speed. 

In practice it would mean the ship has a very short sprint range of probably just a couple of hours before the battery bank is depleted and power drop would be substantial.

[Desertfox]
