This is what the person saying the SW could be used as a WMD used a scenario: play yo-yo with a planet in one system until you build up an Armageddon-event level of velocity, travel to another system, fly the ship into the target.

Ships with fuel cells and MHD turbines don't have the endurance to do this. A ship with a fission or fusion plant could do this, but such ships are large expensive and uncommon.

Sounds doable...

So we might want to keep an occasional eye on gravity wells, both locally and in nearby star systems?

I meant for the final crash. You mount up your speed for some months at a uninhabited system, they you fly your ship to your target, that will likely have atmosphere, and then the likely effect, 2300AD ships being as they are, is that the ship will disintegrate in atmosphere.

I'm not sure nuclear power plants are so rare in 2300AD setting. See that fuel cells or MHD ships have quite short autonomies, and wilderness refuelling, while not unheard about, is rare.

A ship not expected to move along settled space, as an esplorer ship, would be likely to be nuclear powered, as both fission and fusión power plants have quite longer autonomies, and the missing of such a ship (that use to perform long exploration trips) will not be so noticed...

Sorry, I misunderstood you.

I don't have Star Cruiser, so I don't know what the size and cost of nuclear plants are in the GDW version.

In MgT 2300AD, the smallest fusion plant is nearly double the size of a Thorez and costs more than 4x as much. The smallest fission plant is about a third the size of a Thorez and costs half as much as that ship.

Neither do I have Star Cruiser, but the Killiecrankie ship shown in Challenge #37 was not told as a large ship, and was nonetheless fission powered (precisely due to the need for endurance).

When I tried to convert it to MgT 2300AD, it could be done as a 600 dton ship, so far from the largest merchant or military ships...

And, also for MgT 2300AD, my own designed jump frame, when not carrying any interface module, is 400 dton, and equiped with a fission plant large enough to power it at decdent Warp Efficiendy when carrying all 8 ones, and so being 2000 dtons... See the different perfromances of both desings, the one in the OP, MHD powered. and the redesign in post#5, fission powered.

In fact, once you need a power plant sized M or more, the Fission one is quite more efficient, as in 70 dtons you have it with quite long endurance, while an MHD would need 26 dtons just to fuel it for a day, so, even descounting the mass of the power plant itself, 3 days of endurance use more volume than the fission plant itself...

Are 2300 ships immune to radiation? Otherwise the collisions and radiation produced by hitting matter at frac-c speed for months would make such a tactic rather impractical.

Given that the ships are not built to have much speed at all in normal space it seems unlikely?

People would probably not be able to endure this radiation, you're right, but if the ship has to be some months in this, due to other life support matters, it cannot probably be crewed by people, but be robotic or drone, and I'm not sure how will this radiation affect it.

It seems like there's so many cheaper options for ne'er-do-wells to cause mass destruction in 2300. Stutterwarp missiles are already stretching the bounds of "tantalum is super rare so don't waste it". A ship big enough to have the endurance to get to relativistic velocities only to destroy itself with a lithobraking maneuver...would be big enough to not be easy/cheap to acquire.

You could instead attach a mass driver and nuclear fission plant to a couple of asteroids and Footfall the target. The ships needed for such an operation would be totally reusable. There's also conventional (and nuclear) ortillery. Warheads launched with high acceleration booster from ships in orbit would enter the atmosphere so quickly they would be incredibly difficult to defend against.

There's also the small problem of the French Peace. If you're caught setting up such a weapon your home town will get turned into a self-lighting parking lot.

That's fine for militaries, but not for terrorists.

Er.


Stutterwarp doesn't add normal space velocity, it sidesteps Newton by scaling up microjumping.


So the stutterwarp field shuts off, ship should have the velocity it had at stutterwarp initiation, or arguably none.


So IMO stutterwarp ships hit grav fields of the planet it stops, and just plinks into the planet.


Now, there is one other aspect of the stutterwarp that might be an issue.


Since you are effectively teleporting entire ships into X space ahead of the original position, the ship could be set to rematerialize inside a station or other fixed object not stutterwarping. That might be a messy fusion event.


The main stutterwarp WMD I came up with was an anti-matter warhead. A mini-stutterwarp takes a bottled isolated chunk of anti-matter and stutterwarps it into the same space as a duplicate of matter and- kaboom.
