I'm scratching my head as to why my Jump Stabilisation Ship is tracted at a meager 342 km/s. Is there a penalty at some point if the masses of the two ships are vastly different? 
My Tug is 10,000 tons and has a speed of 2400 km/s. My Bïfrost JSS has a base speed of 333 km/s. So what gives? 

There are two important rules here:
  • A ship under tow does not contribute its own engine power to the speed of the fleet.
  • The speed of a tug plus a ship under tow is determined by the tug's engine power and the total mass of both the tug and the towed ship.

Given this, you have a total of 480 engine power on the tug, and a total of 70,000 tons (tug 10,000 + station 60,000) or 1,400 HS. 480 EP / 1,400 HS * 1,000 = 342 km/s, so the numbers check out correctly.

Factors (in real world):

Star Radiation Strength
Distance from Star
Rotation of body
Atmosphere
Albedo
Stefan-Boltzmann Constant

In Aurora, the atmosphere and albedo are not part of the calculation for base temp. They are part of the calculation of surface temp.

I don't think the Stefan-Boltzmann constant is part of Aurora's model.

Does anyone know the calculation for the current base temperature of a system body?
I suspect it's a simple matter of star brightness and current distance from star.

Prior to eccentric orbits, the base temperature of a body never varied, so I could just use the value of FCT_SystemBody.BaseTemperature.
But that value seems not to vary over time.

well there is this:  https://www.astro.princeton.edu/~strauss/FRS113/writeup3/ but I"m not sure it is quite that complex in game.

Factors (in real world):

Star Radiation Strength
Distance from Star
Rotation of body
Atmosphere

Thank you all for the answers to my questions, it was quite informative.  :)

Have to ask, there are Troops actually aboard said ship?

Asking from experience...

Yes yes there were troops aboard  :)

I figured out the issue, I had to create a colony before, Jesus Christ.

The Chantry of Light Month 75

Starbridge Station, Lathandras Orbit, Thedas System

From the observation gantry just above the stations CIC Templar Captain Allistar Ti'Lir could see the work ongoing at the yards that made up the bulk of the stations volume.  The Enchanter was progressing, if slowly, its frame complete and artificers, workers and robotic drones starting to assemble its spinal weapons array.  Ships floated in other docks, their armour skin open to space as others worked on their system.  This month would see the Shield's refits completed excepting for the 7th squadron's 3 Fearless Destroyers.  They were currently on station in Sarnia while all other battle riders were here refitting or else shaking down. 

He could not see the latest Pathfinder vessel, the Spectre was beyond the moon doing its space trials.  It would be the eyes of the Pathfinder flotillas.  The plan was to replace the 18 Seekers currently in each Flotilla was 10 refit Seekers and 4 Spectres.  This would double the survey speed of each flotilla in addition to giving each one four ships with enhanced sensor reach.  This would increase the maintenance of each flotilla to 480.2 MCr.  That was a 14% increase and a fifth flotilla would be added, with 22 Seekers mothballed.  Three new patrol squadrons had to be built with at least part of their complements coming from the Defence Force itself as it was clear a significant re-organisation was needed.  The Fearlesses would be used with Swiftsures as leaders, and the Peacekeepers and most of the Grace Knives relegated to patrol duties.  It would require some changes to the current squadron structures and the construction of more Dawnbringers.

What to do about Sarnia though?  Even now the Fold points were not fully explored and trying to build or assemble when the latest mobile repair docks were available would still take a long time.  But clearly something needed to be done to increase the number of eyes in that system.


SEEKER R1 class ES        12 Hull    TL 3
[2] SAXiHLQsJc1 [4]
12 RCP  13 MCP       Trg:1        Cost =  186/ 27.9
HTK 7   Sx1  Ax1  Lx1

The improved survey instruments replace the ageing standard systems of the original ships.  To accomadate the increased array size of the new survey instruments part of the ships shield generators were sacrificed. 

SPECTRE class CT        16 Hull    TL 3
[2] SSAXiHXrLQsJc1jc1 [4]
16 RCP  9 MCP       Trg:1        Cost =  261/ 39.2
HTK 10   Sx2  Ax1  Lx1 

Incorporating improved survey instruments and the recently developed phased array and sensor enhancement computer systems the Spectre is twice as efficent at survey.  This ship is intended to perform probes as its sensor range is substantially increased. 

HALLA (TUG) class FT4     30 Hull    TL 3
[3] SAJc1x8TTJc1Jc1HQsJc1 [4]
30 RCP  45 MCP       Trg:1        Cost =  242/ 18.2
HTK 17   Sx1  Ax1  Tx2

The Halla will allow the Shield to move its Sentry bases around, enabling them to be constructed at single fixed point rather than needing to be built on station.  Why bases can't be transported in jump racks is beyond me!

House Rule Change for J-small craft
Starslayer and I talked about this and we settled on the following speeds for J-small craft:
Cutter:  Tac Speed 10 Inter-System Speed 3  (Speed of a DD)
Shuttle:  Tac Speed 9  Inter-System Speed 3  (Speed of a CA/CL)
Assault Shuttle:  Tac Speed 12 Inter-System Speed 4 (Speed of a CT)

This would allow us to have fighters starting at Tac Speed 13-ish if we decide to go with fighters at all. Pinnace's are going to take some thought and back and forth since they would need to be Jc based.  I also admit I have a lot of trouble with kinetic interceptors not killing fighters a lot better than they do.  Given they do damage to ships, something no other pointdefence is capable of, and given their tracking capabilities smacking a fighter out of the sky seems like it should be childs play.
