Nice straightforward fleet oiler.  Of course I wouldn't necessarily call it 'heavily' armed.....but hey, I'm building fleet tenders designed to transit the Yucatan Strait.....so they're a bit 'punchy' for fleet tenders to have a chance to survive that.

[Kaiser Kirk]

Several notations

A) availability - everyone has 'sufficient' oil - stemming from home territories.
Oil in the territories is based on if that area had oil
As a hand wave, "naval bases" and "port symbols" have enough for 1-Halfyear of operations by the regularly assigned ships.

B) civilian co-opted - also as part of Snip's design, there are civilian tankers floating around which will divert to support when the player demands.... but they will amble along at 8-12knots and their local number/ size may not as desired.
So building some additional vessels as fleet train can be helpful.

C) Weaponry/Armor vs. Cheap warship
As Foxy observed long time ago, a large aux such as my 'Whale' class can have a substantial battery.
The 2% is based off 'normal' not 'light' which gives a bit more wiggle room.
That is how my Hakma class manage a light TDS.
In the end, large merchants such as this oiler still 'cost' 3.2 BP.... and are not nearly as capable a warship/commerce raider as a proper 3000 ton cruiser....though those are weak as well.

D)  A note on oil as range rather than miscellaneous weight.... we've never really had that discussion, I have this vague impression Snip planned on refueling fuel being part of misc wt, but I can't find a policy to that effect, and I don't understand why it would be that way.
So fuel as ...fuel works fine.

E) How much
That said....I'd take a look at your total bunkerage weight, and compare it to what you need to resupply a single deployed battlesquadron.

The new Centaury class carries 2473t of fuel for just itself. This oiler is 3125t.
Your  "torpedo boats" had 300ts and the T-U are now up to 500t of fuel, which means your oiler can refuel 6..torpedo boats.

I don't know the design intent, so I can't say if that's plenty or not quite enough.

[The Rock Doctor]

The bunker is just bunker.  There's 8200 t of miscellaneous weight for oiling thirsty ships.

[Kaiser Kirk]

The bunker is just bunker.  There's 8200 t of miscellaneous weight for oiling thirsty ships.

How'd I miss that?
Anyhow, I'm unsure of why/if it needs to be misc wt.
Opinions?

[The Rock Doctor]

We used, or at least tolerated, bunker-as-fuel-payload in previous versions of the sim.  I did it myself, I think.  Seemed reasonable given that we weren't paying for the fuel in other ships (costed at light displacement) so we might as well pay for oilers in their unloaded state.  But I think the beginning of this sim may have received direction to use misc. weight.

That argument could probably be applied to dry cargo as well, perhaps, but for now I'd be satisfied just to apply it specifically to fuels.

Anyway, not sure how you missed the miscellaneous weight. 

Oil supplies not withstanding, one place where the Union anticipates needing it - yet still not having it - is in the mid-Atlantic after sprinting around the British Isles during a conflict.  Otherwise I'd not necessarily be worried about it.

And all that said, I suspect I'll shelf this and opt for a couple more big depot ships instead.

[TacCovert4]

Bunker as fuel could work just fine.  But as was noted, typically we're looking at supporting more than just fuel with our replenishment ships.  Also, the rule on X tonnage of misc weight supports Y Tonnage of shipping was put in place.....probably so nobody has to actually calculate the full tonnage of fuel requirements for their fleet on various voyages.  As it stands, I consider the 'cargo' bunkerage to be its own separate tanks and that the tonnage covers the 'void space' as well as the steel needed to build out the various fuel bunkers and cargo holds.  While yes, any of my replenishments ships would probably 'piggyback' its own bunker fuel into a ship that needed fuel....the standard operating procedure for the RAN is to maintain the ship's own bunker capacity for itself.

[Kaiser Kirk]

Sounds like both Rocky and I are remembering the same Mod Clarification from Snip's tenure of <1912.
So lets keep to the Misc wt for now ?

Anyhow,
Miscellaneous weight dedicated to the 'Fleet Support' role would still be needed for any Fleet support tonnage.

This is more about resupply of a base or fleet, where X tons of oil gets split among Y vessels.
Anyhow, if we wind up in an involved discussion, I'll split it into it's own thread.

[The Rock Doctor]

I do stick with miscellaneous weight as the unambiguous location for fleet support tonnage, no worries there.

[The Rock Doctor]

The Z-class torpedo-boats are, again, incremental updates on the preceding T-, U- and W- class boats but I decided to sketch this one.

It's a bit faster than the W-class because I need the engine weight to stay above 50%. 

The primary difference, really, is that the single 100mm AA is replaced with two twin 50mm/60 cal installations for a heavier volume of fire, albeit at reduced ranges.  The gun's still in development in H1/29, so the lead units will receive them via refit.

Like the W-class, a run of 16 units is anticipated.

An excellent, powerful and classic design.

Current thinking on the 1929 Rajtar-class armored cruisers.  This is very much viewed as a cruiser-killer/trade defence/scouting platform, with no delusions about standing in the line of battle. 

The armament is a very new 250/50 cal gun with heavy shells.  A conventional secondary and lighter battery is installed, but I might have early DP mounts in service before she's completed and there's a possibility I'll refit in a 130DP + 50mm battery in exchange for the current 130LA + 100AA arrangement. 

Armor is intended to protect against cruiser gunfire.  I contemplated omitting the TDS but that only saved about 5% of total cost and didn't seem to be worth the meager savings.

The high seakeeping is mostly incidental, but it isn't a bad thing if the ship can ride out Atlantic weather conditions.

I'm considering a run of four hulls, every six months.  These would replace the two Grenadjar class ships and otherwise boost the number of mid-sized ACs to eight.

I think the extra 3000t is well placed, giving you a lot more survivability.  As a rule of thumb for me, any cruiser over 8000t is going to have a TDS....heck most of my ships over 8000t have a TDS no matter what.

Speaking of flight-deck cruisers, here's a hypothetical - the laydown date is the earliest I could have a quad on something.

Still, you get decent self-defence and sixteen post-'33 airplanes, so it ain't bad.
