I started thinking about the J-3 haulers running the Anthorann/Gamelea – Anar/Lymethius route and about the sheer amount of cargo involved in the trade between star systems.
The Bryak – Anthorann Run has a Bilateral Trade Number of 10.5. The Anthorann – Anar Route has a BTN of 10, as does the Rimward Run from Gamelea to Gaidon and from Gamelea to Miazan. The 10.5 BTN-rated Spinward Run from Bryak doesn’t actually end at Anthorann. It doglegs Rimward via Kalar-Wi and then Spinward to Yuakteisye in the Huiha Esoyatre. After downgrading to a BTN of 10, the route then turns Coreward for ten parsecs before terminating at Lysarnor in the Geithurian Republic.
So, what do these numbers mean? According to
GURPS: Traveller Far Trader, a route with a BTN of 10.5 generates 5 – 10 million tons of cargo per year, or 100,000 – 500,000 tons per week. A BTN 10 trade route has 1 – 5 million tons of cargo per year, or 50,000 – 100,000 tons per week.
If a standard Type A2 200-ton J-2 freighter, such as the
Empress Marava from
Supplement 7 - Traders and Gunboats, has a 46 ton cargo bay, then we would need between 2174 and 10,870 ship movements per week to move all freight on a BTN 10.5 route, or 1087 – 2174 ship movements per week on a BTN 10 route.
Now most of the routes I described above are Jump-2, and so could be serviced with multiple small ships, but there are a couple of J-3 gaps which either have to be bridged or weeks added to shipping times. It’s this necessity to bridge the Anthorann – Anar Gap, or the Gamelea – Rimbaud II Gap, that opens the door to higher Jump capable freighters. And if one is already paying for Jump-3 on a high-traffic route, then one might as well move as much cargo as possible at one time – so, enter the Megahauler.

With a cargo capacity of 7400 tons, only 14 – 68 movements by a
Daiishaluur Class vessel are required each week on the 10.5 BTN routes, or 7 – 14 movements on the 10 BTN routes. With a
Daiishaluur and its five Lighters costing MCr 9,176.865, some 138.7 times more than the MCr 66.175 for a Far Trader, but a
Daiishaluur’s cargo capacity of 7400 tons massing 160.9 times the
A2’s 46 tons, one would hope for a saving on these routes by shifting cargo in mega bulk. When you factor in the
Daiishaluur’s J-3 range against the
A2’s J-2, then on the longer hauls, the
Daiishaluur should begin to pull ahead.
I opted for a basic TL12 build for the
Daiishaluur Class as, given the average Tech Level of the Border Worlds, I surmised that the
Daiishaluurs could be serviced at most Class A or B ports, much like
Type-S Scouts and the ubiquitous
Type-A2 Merchant ships. Upon checking system Tech Levels against Starport types and Yard capacity, I found that very few TL 12 systems in the Border Worlds had an A-Class Starport (required to build jump-capable starships), and of those that did, only Miazan/Miazan possessed enough capacity to build a 20, 000 ton ship. In fact, given that Miazan has a Yard capacity of 6.3 million tons; it is more than likely that several
Daiishaluurs are building at any one time to claim the discount for quantity.
It would seem, then, that the
Daiishaluur Class Megahauler would be seen operating the Miazan – Exxilon – Tonivar – Celephais – Rimbaud II – Gamelea Run and it’s possible that some might do a grand circle from Miazan out into Cabria Subsector via Lo Taisang – Yuar – Brol – Gyffd – Tonivar – Exxilon – Miazan, which scoops up most of the 5,000 tons – 10,000 tons of trade a week from Lo-Taisang – Yuar and a chunk of the 10,000 tons to 50,000 tons going between Yuar and Brol. While most of the Grand Circle is beyond the Imperial Border, the Gyffd – Tonivar leg neatly over-jumps Kalar-Wi space in the event of tensions in that region. Alternatively, a savvy ship-owner could offer an alternate run from Gyffd to Yuakteisye in the Huiha Esoyatre that would cut at least two weeks off the standard J-2 route through Atlasiykh.
While messing around with High Guard Shipyard, I reran the
Daiishaluur Class design parameters for a TL15 ship. The result is the

Non-Jump Capable fuel and cargo lighter for a megahauler.
This was quite an interesting little exercise. At TL15, the 20,000 Megahauler is about MCr 3,000 cheaper, has 12 fewer crew, 1,300 extra tons of cargo, and the laser batteries are more effective. Also, the Lighters are MCr 31 cheaper and can lift 31 more tons of cargo. Gamalea/Gamelea has a Yard capacity of over 35 million tons and so could pop these out like melon seeds. The Bryak – Anar Run is the most obvious place to encounter these ships and they could also make the three parsec jump from Anar to Jul’ni in the Geithurian Republic and pick up the major trade route running Coreward towards Lysarnor.
It is unusual for merchant vessels to have centralised fire control and their turrets organised into batteries. Given the strategic value of these megahaulers; the fact that some of the routes they travel – such as Celephais/Miazan – Tonivar/Cabria – are creations of Imperial Policy, and that the Imperial Army relies upon seconding these vessels to provide heavy lift capacity in wartime, then the provision of limited end-user certification for Navy surplus centralised fire control systems is a mutually beneficial action on the part of BuShips (the Imperial Navy Bureau of Shipping). And so, with the TL12
Daiishaluur Class Megahaulers coming out of Miazan and the
High Veenoir Class Megahaulers coming out of Gamelea, the major trade routes are quite adequately serviced, trade is protected, and Ground Force Lift capacity is ensured.
The next step, for me, was to work out how much it costs to run these monsters and whether the freight hauling business could actually sustain ships of this size.
