Just because a technology is possible is no guarantee that it is actually developed at any specific time in any particular universe. In the OTU these prototypes just weren't developed as early as they could have been.note that T5 would allow experimental drive at TL-3, so J5 TL 14 are a theoretical possibility (huge disadvantage involved of course). We have to use the cultural explanation for the lack of Vilani prototype J-3 in the T5 TU.
This is one of the silliest new rules in T5.note that T5 would allow experimental drive at TL-3
This is one of the silliest new rules in T5.
It has no real world examples and it has ridiculous unintended consequences.
That's not the way the rule is presented nor is it how it works in the real world.
In a steampunk like alternative universe you may have Victorian scientists building experimental fusion reactors and air/rafts, but in the 'harde'r sci-fi of the OTU this sort of silliness has no place.
I came across this while going through Library Data, and it appears both in the Classic Library Data Supplement and also Mongoose Library Data, so I assume that it is as official and canonical as it can be.
From this it appears that the Vland Imperium was limited to Jump-1 and Jump-2 drives. The questions that follow are based on this.
1. Did Vland only have Jump-1 and Jump-2 ships?
2. How long does it take to get from Vland to the vicinity of Terra at Jump-2?
3. Is there a route to Terra from Vland which only requires Jump-1 and Jump-2?
There is also a problem with this idea of limiting Vland to Jump-2, as looking at the Tonnage-Drive Table in Starter Traveller (which I have on my computer), Jump Drives F and G will give you Jump-3 in a 400 dTon ship verses Jump-2 in a 600 dTon Ship, while Jump Drive H will give Jump-4 in a 400 dTon ship verses Jump-2 in a 600 dTon ship. Even in a Small Ship universe, those are not very big ships. The listed Drives are available at Tech Level 10, which I assume represents the Vland Imperium Tech Level at a minimum.

Explained in Rim of Fire and Interstellar Wars. The Terrans located a brown dwarf halfway between Terra and Bernard's Star.Hmmm, amazing what you find when you look at maps. I checked the Solomani Rim supplement, and discovered that Terra has no Jump-1 stars, only Jump-2 or higher. So for Terra to start expanding in terms of interstellar operations, it either used a Jump-1 ship with fuel for two consecutive jumps, one in Deep Space, or they had to wait until Jump-2 was around.
I agree with you if it means that a TL 15 planet in 3I may build experimental TL 18 stuff.
As for those prototypes, I'd allow at maximum to build them one TL higher, as MgT allows (or at the specific TL if using something like the TL profile given in MT:WBH)
The Ancient black globes that the Imperium worked with were TL 19 or 20 or 22, something like that. The prototypes they developed for testing in the Kinunirs were TL15.Not sure if I'm disagreeing with you , or not, but the TL15 Imperium did experiment with reverse engineered black globe generators and antimatter.
(Not sure which TL's these are 'normal' at).
And if they missed that, they could have just carried a double load of fuel anyway (and what about refuelling tenders? Would such things be possible?)Explained in Rim of Fire and Interstellar Wars. The Terrans located a brown dwarf halfway between Terra and Bernard's Star.

The attempted explanation for various facts about the Interstellar Wars (basically that neither the Terrans nor the Vilani tried to bypass the other side's planetary defenses by jumping in behind them) is that prior to late in the Long Night, calculating a jump required a planet-sized object at each end of the jump.And if they missed that, they could have just carried a double load of fuel anyway (and what about refuelling tenders? Would such things be possible?)
They couldn't... the early Terran drives couldn't (for whatever reason) make jumps to/from deep space. Perhaps that's the difference between true TL9 and TL10 JDrives?
Read post #32 of this thread.If all Terra had to start with are Jump-1 drives, and they could not jump to deep space, how did they expand? There are no stars in the Solomani Rim supplement within one parsec of Terra. And not that many within Jump-2.
