Re: Another stellar navigation question:

Well, 'stable' is a variable term in this case. Look at Alpha centauri/Proxima centauri. It's a trinary system, but the two Alpha stars, both yellow dwarves, have an eccentric orbit, and they pass anywhere from 11 to 30 AU from each other. And Proxima is way the hell out there at 15,000 AU. The orbi...

Re: Adventures In the Perseus Cluster

The high radiation would produce some hardy life forms. Not sure how, or if, it would affect jump travel. Nebula would not affect jumps, but maybe with more debris inside of the region you might have stricter jump 'paths' that ships would have to follow to navigate between worlds. In a 'dirty' enoug...

Re: Question on the 100D jump limit

I have come up with a house rule that every planet within jump range (previously just J-6) had a set of pre-determined sections of space allocated to each planet. So if you had three planets with starports in System A, each would be assigned it's own orbital area outside the 100D for arrivals. Each ...

Re: Suffocation in a Stateroom

I would assume that the entryway would be airtight for staterooms. They may not do as well under explosive decompression, but from a safety factor it would be a great safety thing.

Suffocation in a Stateroom

I was trying to do some back of the envelope calculations on how long a person could survive in a stateroom if the life support had failed. Assuming I did my math right, a person would become unconscious in about 8hrs in 1 dton, with their capabilities being severely reduced within just a few hours ...

Re: untested house rule

It would really depend on whether or not they had any sort of related skill to apply. Otherwise an Admiral with 40yrs service is going to be as clueless as an 18yr old when it comes to birthing triplets or some other non-related task. The most educated and skilled character might lose their lunch at...

Re: Large Scout Ships?

Yeah, I'll pass on agent book. While T5 is official (and I'm a kickstarter backer), it's a dust collector as far as I'm concerned. The Empress Wave is something that I've never bothered with or done much with. And one would have to figure out if it's going to be part of the Traveller universe or not...

Re: Need a quick ruling - missile countermeasures

Self guided missiles shouldn't need any of that. They are essentially fire and forget. Though they should be fed the target information and a lock prior to launch.

Re: Rat Trap

Would really depend on the mystery you are planning and how much obfuscation and sleuthing there is supposed to be. Poison in the vodka set the stage for someone wanting to kill or disrupt the mission. If that's what you want, fine. However if you want to keep them guessing about the true culprit or...

Re: Large Scout Ships?

The role of the scout service is one that doesn't really require large capital ships. They have a bigger need to be more places simultaneously than needing to be in a fewer places with a bigger stick. Canon disagrees. The IISS had 40,000t cruisers on twenty year mission exploring beyond Imperial sp...

Re: Great White Fleets... in spaaaayyyccceeee!

The early warships were, well, built using some interesting standards. Then again the standards were pretty damned irregular. Battleships with almost no armor, carriers with spinal mounts just to name a few things.

Great White Fleets... in spaaaayyyccceeee!

There is a discussion going on the Facebook Traveller RPG group about what the optimal capital ship size is, and in the comments it was tossed out about what size ship makes for a good showing of the flag. Which is a valid point since if you have a mighty 500,000dton warship vs the local 10k dton sh...

Re: Need a quick ruling - missile countermeasures

That's true, but processing in the far future is no different than it is today, only faster. It's not like you need petaflops to do this (which is probably the norm for a 52nd century CPU on a seeker missile). It's literally rocket science that we do today.

Re: Need a quick ruling - missile countermeasures

Close range is 10 Km, thrust 1 is 6,000 km/h. The slowest missile is thrust 6. (shrug) speed of light is still much faster. That's the speed that electronics operate. It's well within their operational parameters. Electronics on a missile would be hot and primed prior to launch (unless you are a to...

I think it would be easier for us to ask you to re-state your question. The wording is atrocious and the question makes no sense.

Re: Need a quick ruling - missile countermeasures

Consider the speed the missiles are going at where thrust 1 in atmosphere is considered 6,000 Km/h, with missiles typically between thrust 6-15. That presents a window where the missile doesn't have time to lock before its launched, ideally you would avoid doing so. Further, missiles have a termina...
