Jump-4 in the Imperium

[Gadrin]

According to the Milieu-Zero PDF I have...

The SFSS started
from a zero-line of the existing Federation boundary, and,
following its new modus operandi, pushed out to the previously
explored limits by Year -10. After that, and assisted
by the new Jump-3 drives, they expanded along the
whole of the “near shore” of the Great Rift, through
Gushemege, Verge, llelish and Zarushagar.

And my GURPS Traveller Timeline shows that the X-Boat System was established in 624.

So I'm guessing J-4 came in around 300 to 500

Hmm, unless I misremember, that might be right. TL13 was achieved around then... right? (Doesn't MegaTraveller record all this in its Imperial Encyclopedia?)

MT-RC says TL-13 (J4) in 300 and TL-14 (J5) in 700.

The Xboat network was built between 624 and 718.

 

[Border Reiver]

The X-boat network was established as a direct result of lessons from the 1st & 2nd Frontier Wars as well as the Civil War. A smart move by Arbellatra.

 

[Gadrin]

Ah, great, thanks one and all !

 

[Maladominus]

MT-RC says TL-13 (J4) in 300 and TL-14 (J5) in 700.

The Xboat network was built between 624 and 718.

And I recall that Imperial TL-15 was achieved right in the middle of the Solomani Rim War.... just in time to allow the 3I some small technological advantage over the TL-14 Confederation? *shrug*
