[Pirates of Drinax] Game of Sun and Shadows - supply lines

Postby Pyromancer » Sun Jul 22, 2018 4:46 pm

In "The Game of Sun and Shadows", it is stated that the Imperial punitive fleet at Byrni is supplied at least in parts from Tobia. How is this managed? Did they send a message to Tobia before they left Pax Rulin? "When you receive this letter, please send a supply ship a week to Byrni, we will be there when they are." And those ships carry just about everything that could be needed, because ordering specific things would take half a year? Sitting at the end of a supply line that long for an extended period of time sounds insane.

And what kind of ships would fly those supply missions?

Fleet supply ships are typically either armed merchantmen or else custom designed ships. I would say the Imperial navy would use the latter. A single ship would be designed to support a destroyer flotilla, or cruiser squadron and supply parts, ammunition and make repairs short of requiring a yard.

One should be at least 5000 tons, if not 10,000, depending on how much fuel is required for its range. It doesn't need to be fast, and it's not going to have much more than self defense armament. It should typically take up duty station for 3 to 6 months and then return to port for resupply. Crew will be split between the normal ships credit and all the engineers and support personnel who do the work. You coukd even have a dedicated command section for higher ranked commanders if there is no port available.
Small craft would include engineering support vessels, plus smaller ships to distribute supplies to ships not directly docked to it.

The ship would have a fabrication section, electronis repair shop, enginger ingredients repair ship, small craft repair shop, spare parts cargo hold (s), ammunition storage, food and other general supplies hold (s).

More than likely it will support and repair ships docked both port and atarboard, possible even dorsal and ventrally, but that may be getting too busy. Each side would have airlocks, cranes and repair gantries to facilitate repairs and make it easier for personnel to go to and from.

There is a wealth of information out there for how navies have done this over the last century.

There is a smaller 1,000 ton Imperial Navy tender in Supplement 10: Merchants and Cruisers. Not intended to resupply large fleets.

And also one in pirates of Drinax, the patrol tender on p.32.

The larger tender that phavoc spoke of sounds like three patrol tenders and two magenta repair ships (also from Drinax) merged into one ship, or twice that depending on size.

A tender is meant to both resupply and repair, but mostly repair and support vessels when it's more convenient to repair them close to the front rather than sending them far to the rear.

Resupply vessels tend (today at least) provide food and ammunition and general stores to vessels. Fleets generally have their own supply train, including both tenders and resupply ships.

A fleet designed to inflict damage is going to expect damage in return, rhus it would be more appropriate to get a tender rather than a plain resupply ship.

A 1,000 tender would be too small to support a desron, let alone a cruron.

To give context for the campaign:
The Imperial fleet at Byrni consists of a 75,000 dton heavy cruiser, a 100,000 dton superfreighter, and a dozen smaller ships between 400 and 8,000 dton.
According to the campaign, they need supplies worth of 8 MCr. a month.

A 10,000 ton tender is not out of the question to support such a fleet. Though the 80k freighter could easily hold their spares, ammunition and general cargo. Plus modules for a portable base and replacement small craft to boot.

Tenders tend to tend to escort ships and smaller combat craft out in the field, or on top of the water.

You could also have milk cows nurturing system defence boats.

Anything larger you're looking at dedicated replenishment vessels, and probably floating docks.

The United States developed the fleet train since it didn't have the Royal Navy's vast network of bases located around the world.
