MGT Only: 200 T J2 Trader - Cheaper better than a Far Trader

[HG_B]

Beltstrike makes it clear that the drives generate a screening force of some kind, preventing that.

I don't have that MT supp. I'll have to look up.

Note that I use the x0.1 damage to structure... which makes it take a LOT of fire to harm the ship in a significant way. In an average trip to the jump point, you should have a couple hits... and that means needing to do some partchwork, but it's well within mechanical 1 capabilities to repair.

The velocities reached at mid point of 100D completely dwarf (by many factors) the speed (& k.e) of a Guass rifle ammo. The ship would be damaged (most likely explosive decompression if a crew or passenger compartment is hit). NO question about that without hand wave so violent that you cause a gale force wind COMPLETELY forgoet about interplanetary travel using the travel formula in the RAW. You'd likely die.


So, as I indicated, forget about loans. Ships would be too expensive to operate. Too dangerous also.

QUOTE=HG_B;494320]In MgT Merc Book: "Because starship-scale weaponry is so lethal to
ground force targets
it is not often that a vehicle or heavy infantry would ever want to
make a stand against a starship. Most ground force weaponry
simply cannot muster enough damage potential to do anything
but scratch the paint of a starship. Starships are shielded from the
void of space and layered in armour designed to withstand raw star
radiation and absolute zero temperatures"

So that carries over what you noted from CT and MT. So the armor you give in MgT is to protect against ship scale weaponry. As in past editions, the example ships are not always well (read wisely) designed.

Gypsy, good catch. My spread sheet had a glitch. Add MCr.0.8 for streamlining. Total is MCr.43,287,300
instead of MCr.42,467,300 In the grand scheme no significant change.

So, by your own quote, Starships are not completely immune to ground fire like your original assertion. MOST is not ALL. MOST weapons won't penetrate a tank. Some will. Like the Missile I originally proposed.

A zero armor value gives you nothing to use to degrade the performance of an inbound anti armor missile, or an inbound anti aircraft missile. Or a PGMP-15 hit. OR...

It will withstand small arms fire. But kinetic energy kill weapons like a sabot round? Specifically designed to penetrate several inches of armor, when your ship has NONE?

All your armor-0 means is that the hull is thick enough to stay pressurized and has anti radiation properties. Does not protect against EVERY ground weapon. Therefore I am maintaining that the design is not a good one for a frontier shipping craft. After all, anti armor missiles are available to purchase readily for settlements to protect themselves from rogue Merc units.[/QUOTE]

According that (MgT:LBB1: Mercenary, page 73), in MgT, the damage from personal to starships change by a factor of 50. Even so, in the example it gives, the damage of various weapons is commulative , as it tells about firing various wepons (9 FMGP, 15 lasers, and one AT gun) that sum 122d6 damage, and then divide it by 50, so making 2d6 damage to the ship.

That surprised me, for this way, even a company of flintstock muskets (or archers, or even throwing stones, if enough of them) firing at a ship could seriously damage it...

An unarmored MgT hull can withstand (per the interplanetary travel rules vs. small particles * speed) about 10X the k.e of a 120mm MBT APDS round. Is that enough for you to do your calcs on?

Now, if you had a 6G ship doing interplanetary travel...

hitting 1/10 gram particle during 6G trip to Saturn. Top speed 9160 km/s

= 4,195 Mj
= 4.19528E+16 erg
= 4,195,280,000 newton-meter
= 3,976,358 BTU

120mm APDS 9 Mj muzzle (M1 MBT gun)

Now as to MT. The design rules state: "Spacecraft require a minimum armor value of 40 for protection against micrometeroids and radiation" THUS, there is no drive force field. (see also Starship Op Man.) And, that value would utterly stop any man portable weapon. So, the PEN rules are screwed. Need to at least amend to require a Pen value LARGER than the armor value to do damage to ship hull.
