Fleet Scouts

Spinward Flow's treatise is timely, but it's happenstance as I've been thinking of this recently, tangentially related to what SF was writing about.

Specifically, I'm curious about the naval Scout Train that I have to assume follows every fleet movement.

Simply, there has to be a way for the fleets to inform command of what they're doing, where they are, and where they're going in order for command to have better "eyes" on the battle front, coordinate forces, and keep the lines of communication open.

The ubiquitous Scout/Courier (in the Courier role here) is (probably) the mechanic for this. They seem to be everywhere, they're small, they're cheap, but they're only Jump-2. I don't know if there's a canon fleet courier with a higher jump or not.

The question is how this is manifest. I visualize several of these escorting every major fleet, with several more constantly in flight, like runners at the front. Anytime anything of consequence happens, one (or more for redundancy) are dispatched to a forward command post. Ostensibly, the command posts would be part of the J6 linked systems.

Meanwhile, we have to deal with the Scouts themselves. Their travels, hooking up with the fleet, finding their way. Having them navigate along a Gas Giant trail in order to keep up with the major fleets.

It's easy to see Scouts jumping in to systems blind, told "this is where the fleet will be" without knowing whether it's true or not. Would they, indeed, jump blind? Pop in tanks dry in hopes that the fleet is, indeed, there, or that, at least, the enemy has not taken control of the system?

The Scout have no real mandate initially to join the fleet, just pop in, seek out if the fleet is there, trade messages, get orders, and, naturally, firstly, refuel.

Do you think that a fleet would leave behind encrypted beacons letting someone know that they were there, and left?

These beacons would simply sit dark, listening for an encrypted command signal to transfer the message. After several weeks or months, it can self destruct, or simply wipe it's memory and go cold. I think they would be very difficult to detect by an alien fleet, can have proximity sensors to self destruct on discovery, etc. I think it would be "perfectly safe" to leave these behind and not reveal even that the fleet had passed through.

Mind, there can always be passive enemy listening posts, doing the same things as these beacons. Listening for broadcasts, energy sources, gathering data, but if you have just microbursts of white noise, dunno how telling that might be.

How effective do you think these could be? Knowing Something jumped in, hovered around a gas giant for a couple of days and jumped out could be valuable information.

The worst situation is a Scout arriving tanks dry in a system with an enemy fleet. They have nowhere to run. I would guess that Scout ships would arrive near one of the system gas giants in the hopes to expedite fueling (which is, of course, a popular place for an enemy fleet to hang out, especially one simply transiting the system).

In the end, they'd like end up with a POW. They could destroy the Scout outright, or seize the ship. I don't think there's any reason the Scout should suicide to elude capture -- the pilot knows somethings (I just left Gamma Hydra and there were all these ships there). But the actual messages would be encrypted or destroyed. Or, "Dude, that's part of the job. See an enemy fleet? See them trying to capture you? Press the big, red "DO NOT PRESS ME" button."

I think the Scout train can survive fleet destruction. Sit back, watch from afar, jump out if it's not going well. I don't think the Scout train would need to be specifically managed. That (barring something really unforeseen) there's "always enough". They can ad hoc tender with the normal fleet train, crews are small, they can be traded if necessary.

I just see a buzz of Scouts flitting about, basically keeping the fleet on top of its 2 week delay.
 
IMTU the silly-huge fuel tank of the canon Type S gives it a 3-parsec range (J2, then J1 -- or vice versa) with careful fuel management.

LBB5 gets you a Type S with J3/2G at TL-13 (even keeps the drives at 15 tons so it could be in a LBB2 standard hull if the ref allows that). You could give it a 4-parsec range (J3 then J1 - or more practically, 2J2 for going out-and-back without refueling) by replacing the air/raft, one stateroom, and the cargo bay with fuel tanks.

The Fleet Courier from S9 Fighting Ships is J6/2G in a 400 ton hull. Its description notes that it is intended for “the transmission and receipt of timely intelligence reports and command directives.”

Not as fun as a rag-tag squadron of J2 Scouts doing all they can to get the job done…

What you seek is found in LBB S9, p20.
The Fleet Courier.

400 tons, Jump-6, 2G, Power Plant-6, Model/6 computer, 2 triple beam laser turrets (2 batteries), 2 triple missile turrets (2 batteries), Crew=5, Passengers=4, Cargo=2, Fuel=264, Purification Plant, TL=15, MCr 254.54424 purchased in quantity according to LBB S9.

In point of fact, the Fleet Courier is basically the only way a message could have been sent from Regina/Regina on 187-1107 and reach Rhylanor/Rhylanor on 201-1107 exactly 14 days later as specified in news reports detailed in the Fifth Frontier War boxed set rules page 7. Rhylanor is 10 parsecs away from Regina, so a minimum of 2 jumps is required for the journey. Jump from Regina to a system 4-6 parsecs away so as to do a quick refueling and be underway in jump space again in less than a day and you CAN make it from Regina to Rhylanor in 14 days.

The system at the exact 5 parsec midpoint between Regina and Rhylanor is Echiste/Lanth (C53A313–A) with no gas giant in-system ... meaning a low gravity (size 5 is 0.625g at the surface), very thin atmosphere (code 3), water world (code:A) with a tiny population (7000 in 1105 according to the Traveller Map website and wiki) who almost certainly would neither notice nor challenge/stop a Fleet Courier from diving into the atmosphere (2G maneuver drive), refuelling (quickly!) in the ocean, and then heading back out into space (2G manevuer again) within hours, refueled and bound from Regina to Rhylanor with the news of the Zhodani declaration of war delivered to the Duke of Regina that started the Fifth Frontier War.

187 to 201 ... 14 days to cross 10 parsecs.

So if you're wondering how it's done ... well ... LBB S9 has the answer you're looking for on page 20.
 
Unless it's a one shot, you need supporting infrastructure for drop tanking.

Also, vaguely recall extensive sabotage, possibly ransonware.
 
Early JTAS news:
the extension of the Imperial core worlds civilian drop tank enabled merchant lines and higher jump no. x boats
GP to build the drop tanks in the Spinward Marches
sabotage at the building sites
an 'accident' which causes a drop tank liner to explode and kill everyone

it's almost as if there were a group of freedom fighters who didn't want more extensive Imperial control for the Marches...
 
I'll assume we're discussing Classic primarily.

Drop tanks developed there, and I believe were refined in Trillion Credit.

Not too inclined at the moment to look it up.

The Gazelles might be the first canon starship equipped with them.
 
I don't even know what Imperillines is. How is this germane to the question about Fleet Couriers? ...


Imperiallines is a shipping corporation within the Imperium with substantial assets owned by the Imperial Family, that maintains a fleet of Jump-2 Type TI Frontier Transports, and partners and/or competes with Delgado Trading, Akerut, and Tukera Lines in the Spinward Marches. See CT:The Traveller Adventure.

The commercial Jump-2 Type TI Frontier Transports operate as cover for the identical Jump-6 Type TJ Frontier Transports that are employed as Imperial Intelligence and Communications assets for the Emperor. See: https://wiki.travellerrpg.com/Imperiallines/secret

I've played around with a T5 design, 100 ton Intruder Scout. It's robotic, with brains installed in the computer and consoles and a maintenance bot. Without support for a crew (just a visiting tech to help the bot), there's plenty of space for high jump and maneuver.

The single turret holds a Commcaster, which I assume is directional, and blasts its data to a friendly ship that occasionally comes by to collect it. It's got both fuel scoops and ice bins, and the purifiers to match, so it doesn't have to go to a gas giant to refuel when it first arrives. There's a Densitometer in the sensor suite just to find the ice.

It can stay on station a long time without the annoying problems the Dark Star had. :)

Sure. Fine. Ok.

What's that got to do with this? You were the first person to even mention it.
 
The trigger was Imperiallines.

The option existed that you could in theory hop twelve parsecs on one full tank plus the drop pods in two weeks, give or take, without getting refuelled inbetwixt.
