Okay, I've done a search and can't find the answer. What is a conversion of Ship weapons damage against vehicles and personnel? Beam Laser does 1d6 ship damage would do what against a Grav tank?
Ship vs Vehicle vs Personal damage

I believe the scale is 4 : 4 : 4.
For example, a starship weapon does 4x damage against a vehicle, and 16x damage against a person.
And in your example, the ship's Beam Laser does 1d6 x 4 damage against a Grav Tank.

Cool, TY very much.
HOWEVER....
Page 151 of the core rules states that "...characters may find themselves using ship-scale weapons on smaller vehicles or even people. Starship weapons are incredibly powerful and destructive -- multiply the damage from starship weapons by 50 to get the damage in personal-scale terms."
So that tells me that your Beam Laser might do 1d6 x 50 points of damage against a Grav Tank. Depending on the size of that Tank, that is.
When the text says "smaller" vehicles, I assume that means smaller than 10 tons, which is the conventional minimum size for typical small craft.
Soooo... if your Grav Tank is 10 tons, maybe it just gets 1d6 points of damage, but if it's 5 tons, it receives 1d6 x 50 points?
But I'm sure I've seen 4 : 4 : 4 somewhere.

I was looking over Supplement 5-6 and Vehicle damage rules TMB and frankly I'm not sure how the weapons scale.

their is a clarifying example in Book 1: mercenary (i think). it shows a example of a bunch of personnel scale weapons (up to FGMPs and a Battle Dress mounted AT gun) fireing at a starship. what they did was ad up all the damage at personnel scale, then devide that value by 50 to get starship scale (ie 6d6+10d6+ 8d6+12d6= 250 points damage= 5 points starship scale).
the mongoose Vechicle design rules seem to keep the personnel weapons scale, with anti-tank weaponry just having large numbers of damage dice, plus armour reducing abilites (for example, 30d6, and ignore the frist 60 points of armour).
so, yhea, i would go with Xd6 x 50 for starship damage to vehicles.

As I understand it, it's not the tonnage what affects it, but the design scale.
So, a 6 dton fighter (should it be posible) with a space rated turret will be considered a ship, while a 40 dton tank built according vehicles rules and with a vehicle FG would be treated as a vechile (and so apply the factor 50 in the damage).

As this thread is discussing damage, the only weapon available in the Supplement 5-6 Vehicle design handbook for ships to carry prior to Tech Level 5 is a 9 pound smoothbore cannon, which is available at Tech Level 3. According to the rule book, Tech Level 3 equates to the early 19th century, while Tech Level 4 equates to the late 19th and early 20th century.
Now, by 1861, the US Navy was casting 11 inch Dahlgrens firing a 166 pound solid shot or 136 pound shell, and by 1865, the US was producing 15 inch Dahlgren and Rodman guns firing a 440 pound solid shot and a 352 pound shell, along with a few 20 inch Rodmans firing a 1,080 pound solid shot. The English built the HMS Inflexible with 16 inch muzzle-loading rifles firing a 1,684 pound shell in 1873, mainly to counter the Italian ships Italia and Lepanto, which were carrying 17.72 inch muzzle-loading rifles (also built in England) firing a 2,000 pound projectile.
How does one scale damage up from a 9 pounder to this size of weapon, all of which were carried by ships? For that matter, the standard heavy naval gun from about 1650 onwards was a 32 pounder, with some use of a 42 pounder.

Hmmmm That 9 pound gun hitting a wooden wagon (vehicle of the day) wagon=:toast: human=jelly
Why bother to figure a 500lb - 2000lb projectile?
As for getting hit with a ships laser or Fusion gun? A grav tank, maybe... A PC? Even in Battle Armor I'm not bothering to roll for that one.

9 pounders were actually quite common ship guns in the early and mid 18th century, on lighter vessals (i.e. 5th rate, 6th rate and unrated ships), and were a calbire also used on land, so it's not unreasonable for them to be inlcuded as the "example" smoothbore cannon. I don't have my copy of the MGT central supply Catalogue handy (it's several time zones distant right now), but it may be possible to "down tech" a TL4 12-inch cannon (i know they have them in thier, and rules for building stuff at a lower tech level in the same book.)
edit: though i admit "go buy another book" is hardly the best answer.......
to give some context, the HMS Inflexible timerover mentioned had a armour belt of 24 inches of iorn, backed up by 17 inches of teak to absorb shock and splinters.
Thats what they needed those really big guns for.

I am not firing the 9 pounder at wagons, but ships, and a 9 pound round shot hitting 2 inches of wrought iron backed by say 8 inches of seasoned oak or yellow pine makes the round shot either cast iron toothpicks or an iron ice cream cone. Firing a 9 pounder at the USS Constitution was a serious waste of powder.
The British did use the 9 pounder as a field artillery piece during the Napoleonic Wars, alongside of the more standard 6 pounder. As for the naval use, the 9 pounder was used by the Elizabethan Royal Navy, and others, as the Demi-Culverin, or half culverin, the Culverin being a cannon that normally used a round shot of 17 to 18 pounds. During the American Revolution, is was the standard main battery gun of the British 28-gun frigates, that were viewed as too light a ship during the Napoleonic Wars, when the standard British frigate as the 32-gun ship, mounting 12 pound main battery guns, and the 38-gun ship, mounting 18 pound main battery guns.

I actually have a current copy of the Central Supply Catalogue, bought when I decided that to understand Attack Squadron: Roswell, I needed to spend some money on Mongoose Traveller.
There is a 12 inch gun there, but I cannot say that I am thrilled with it or its damage characteristics. It gives the 300mm/12 inch gun a burst radius of 13 meters, and a damage of 20D6. Considering that a 12 inch shell is going to weigh between 700 and 945 pounds, going from 9D6 to 20D6 is a bit underwhelming. Besides that, the US 280mm. approximately 11 inch cannon, with a 600 pound HE projectile, was credited with an effective burst area of 200 yards laterally by 60 yards in range, quite a bit more than the 13 meters radius of the Catalogue's 12 inch gun. The 81mm mortar, with a 10.83 pound HE round, had a burst area of 30 yards laterally by 20 yards in range, about the same as the 300mm gun (rated "enormous"). The data on the US projectile burst radius comes from the 1956 FM101-10, STAFF OFFICERS' FIELD MANUAL ORGANIZATION,TECHNICAL AND LOGISTICAL DATA.
Although the armor of the Inflexible was a sandwich of Wrought Iron and Teak, based on tests discussed in Orde-Brown's Armour and Its Attack by Artillery, the sandwich was about 95 per cent as resistant as a single plate, and that would not include the 1.25 inch thick hull plating or the reinforcing Z-bar in the teak. The standard conversion factor for armor equivalence is 2.6 inches of wrought iron equals 1 inch of Krupp Face-Hardened, so the Inflexible would be considered as having the equivalent of 9.23 inches of Krupp Face-hardened plate, which would make it on par with the British battlecruisers that fought at Jutland, the best of which had only 9 inch side armor belts. The muzzle-loading 16 inch guns of the Inflexible probably could not have penetrated her side armor at point-blank range. She was a very, very tough ship.
For those interested, wrought iron and steel armor weighs about 40 pounds per square foot for a thickness of 1 inch.

All very true, I was going with the OP for damage Ship:Vehicle
ersonBasic point being a vehicle, or person, hit by a ship sized weapon is a kill.
