Isn't this what those J6 IN couriers are for?

AFAIK, they're first mentioned in the CT supplement titled 'Fighting Ships of the Spinward Marches' <sic>.

Seems to me that they would be also avail for other official government business, not just the IN's.

Also, remember that early entries of the CT TNS declared that the 3I was just about to embark on a program to upgrade Xboats to J6. The route out to Regina was to be given priority & the saving in transit time from Capital to Regina was even specified.

 I've often wondered why it seemed the IN got ship upgrades
 every
 decade or three, but the IISS was using basically the same
 ship for
 the last thousand years.

 I've had this mental image now and then of a poker game
 amoung the
 3I's Joint Chiefs, where the Admiral complains about having
 to detach
 escorts to carry mail at Jump-4 so they have any chance of
 catching up
 with the fleet, since the Type-S's are only Jump-2.

 The IISS Administrator replies,"Well , if the Navy didn't
 suck up all
 the credits, maybe we'd get an upgraded design..."

 The Admiral responds,"I know the commanders on scene hate
 losing the
 firepower of the escort in an anti-missile role, and it'd
 almost be
 worth it for the IN to fund a new 100 ton design..."

 The Marine General adds,"If it had some way to deploy
 commando troops,
 for behind the lines raids, we'd kick in on the funding"

 The Army General nods, "And the ability to carry the mail
 quicker for
 us would be a good thing..."

 The IISS Admin ponders it, and then says,"The sensible thing
 would be
 to accept that it's going to be _another_ thousand years
 before I hear
 something like this, and design something really cutting
 edge under
 the idea that in 250-500 years it'll be the common place
 technology. I
 mean, Jump-2 was cutting edge when the Type-S first was
 thought up."

 The others agree,and the research project begins...

 .... So, if you were doing a ground-up redesign, what would
 you do ?
