Default Ship concepts and workup's for T4

Ok In the Glisten Subsector I have two high population industrial worlds 1 jump apart with enormous trade between (highly profitable in both directions)
Aki is A port Industrial TL 9 and Hi, while Glisten is AS IN and Hi A-15.

What shipping would we see going between the two worlds?

Concept TL 15 Jump tug 100 Td but the jump drive is sized for 2000 to 3000 Td and uses a drop tank with a twist.

All the grapples are on the drop tank and cargo modules which are designed as space ships with their own power plants and maneuver drives.

A quick rough estimate of the components

Hull <2m3 needed for the bonded super dense 20 armor factor USK spherical hull
605m3, 41mt cost and power can be ignored.
Jump drive for J1@2000 dt =40 Dt (-560m3 1120mt 168MCr -504mW)
Internal jump fuel for deadheading back if needed (-140m3 10mt)
Power plant for 510mw 5 Dt -70.5m3 141mt 14.1MCr +510mW
Computer is set to high automation to reduce crew requirements.
the remainder of the space is the minimal sensor suite, communications computer, controls, minimal maneuver drive, life support, food, and quarters.

45 Dt for all the rest of the goodies

cost is under 190 MCr for the first and around 150 Mcr for the follow on units.

The cargo module is 1900 Dt
has minimal maneuver drive and power and a grapple for a 100dt spherical hull
the usual mode is that it is remote controlled from the starport with some AI for the docking with the jump tug.

Reefer, bulk foods and modularized container versions are produced.

The "Drop tank" is about 220 Dt contains a grapple for a 100 Dt spherical hull and minimal sensors computer and maneuver drive and is always remote controlled and has AI pilot built in to ensure separation and safe distance from the jumping ship.

In practice the jump tug arrives in system and establishes communications and a vector is assigned to it by the starport. the port computers start calculating the outbound jump for the ship, while the inbound cargo module detaches and proceeds to the highport, the jump tug matches course with the outbound cargo module and fuel lighter (Drop tank). If needed a replacement crew is shuttled to the ship and the inbound crew takes a week off in system.

The starport communicates the finalized jump course to the ship which is connected to the outbound cargo and drop tank ships does final course corrections to match the required positioning from the jump tape.

The intent of this system is to maximize the number of jumps per year that this ship is able to accomplish, thereby increasing the profitability of the operation.

*all non So humaniti are much closer related to Homo Nethanderalis than are So, and are immediately recognizable to So as "cavemen" complete with fur and the other morphological characteristics that were unimportant to Grandfather's need for a better servant
