Spaceships in AD ASTRA don't have a price. GMs should keep in mind that making characters skimp and save to get a ship isn't really the swashbuckling space opera way—when they need one, they have access to one. Whether or not the ship lasts the entire campaign or needs to be replaced at some point is, of course, up to you. Keep in mind that Luke Skywalker told Han Solo, "Ten thousand? We could almost buy our own ship for that!" I take this to mean that small, used, and possibly in poor condition ships can be had for about 15,000. Newer models of the same can go for 20,000. Any ship worth having other than a small fighter is going to be up from there. Something similar to the Millennium Falcon should go for no less than 50,000—and keep in mind that although somewhat hot-rodded, it was still a piece of junk. Characters will rarely be buying anything that large unless you run a game that's more about commerce and stuff things instead of action. But if you need some rough guidelines as to ship prices, that should be close enough.
As with Armor (see Equipment) spaceships start with a "chassis" and then you add extra equipment to them as needed. For the most part, the GM should build these up into various models—it's rare that a character would have the chance to make "a lot of special modifications" yourself unless you've had the ship for a long time, and have the cash to acquire some nifty goods.
Ship to ship combat is important in space opera. Ships usually have, as characters do, a move action, and then another action for every full "slot" that they have. A ship can make a "full run" action, in which eliminates the use of a slot action (such as firing a weapon.) Slots are areas in which equipment can be placed—like guns or torpedo launchers, or something like that. Dogfights are operated more like chases than combats (see Combat for details). Slots with weapons in them can be fired if someone is available to operate the weapons. The pilot can usually operate one weapon in addition to piloting. If he wants to operate equipment in any additional slots per action, then there needs to be a co-pilot, or gunner, or someone else around to do it. Robots, even some that are integrated permanently into the ship can count for this total.
To use a ship, you often make checks against the ship's stats, not the characters', due to the limitations of the equipment on the ship. Ship stats are similarly compressed and simplified; ships have a Hit Points stat, an Agility stat, a Sensor stat, an Armor class (AC) stat, and slots for additional "special modifications." The AC stat is derived from 10 + the Agility stat plus any shields or armor added to the ship (if any—in many cases there won't be any.) The maximum amount of armor that can be added to a ship is equal to half of the Hit Point score. Here is a small list of typical actions you can take in a ship, and how to resolve them:
|Perform a tricky maneuver in a dogfight||Pilot's DEX + Ship's Agility|
|Shoot||Gunner's DEX + Weapon bonus|
|Outrun an enemy||Pilot's DEX + Ship's Agility|
|Scan for ships hiding in an asteroid field||User's MND + Ship's Sensor|
The following are the basic chassis that can be used to make ships. They are generalized rather than specific, to reflect the vast diversity of spaceships operating in known space.
|Ship Size||Hit Points||Agility||Sensors||Slots||Comments|
|Small||16||+7||+1||5||1-man light fighter|
|Medium||24||+5||+2||10||Heavy fighter or bomber|
|Large||32||+4||+3||20||Corvette or small private freighter|
|Huge||40||+3||+4||30||Frigate or commercial freighter|
|Gargantuan||48||+2||+5||60||Cruiser, battleship or massive freighter|
|Colossal||55+||+1||22+||100+||Gigantic carriers or mobile space stations|
The following list of equipment can be used in slots. Ships don't have to fill all of their slots.
|Engines (large ship)||2||+1 Agility||—||—|
|Engines (Huge)||5||+1 Agility||—||—|
|Engines (Gargantuan)||7||+1 Agility||—||—|
|Engines (Colossal)||10||+1 Agility||—||—|
|Bulk Drive||5||Allows bulk jumps||—||—|
|Heat seeking missiles||3||+5||3d8||short|
|Heavy radium cannon||4||+1||3d10||long|
|Twin radium cannons||5||+1||4d10||long|
|Heavy EMP cannon||6||+1||special||long|
|Passenger berth||1||5 seats||—||—|
|Passenger berth||3||20 seats||—||—|
|Cargo berth||1||5 tons||—||—|
|Cargo berth||2||20 tons||—||—|
|Cargo berth||3||50 tons||—||—|
Special: EMP cannons disable one of the target's systems for 1d6+10 rounds; heavy EMP cannons target up to 3 systems. While extremely dangerous, they are also bulky and rare, and don't do any direct damage. Gravitic beams allow the ship to make a grab on another ship. To pull a ship into your docking bay against the will of its pilot, make a successful hit with a gravitic beam, then make an opposed check of the two ship's Hit Points + Agility. As you'll see, the larger the ship, the more difficult it is to escape its gravitic beam, especially for smaller targets. The gravitic on a massive space station is practically inescapable by a normal ship, even a large one.
The Damage reduction of shields is the amount of damage that is ignored from most types of attacks. For example, if you have taken shields in 3 slots for your ship, and have DR/6, then for every attack, you ignore 6 points of damage. If the attack rolls up 10 points of damage, you only take 4. If it rolls up 5 points of damage, you don't take any at all; your shields protect you entirely.
Range is not strictly defined. Use GM judgment to determine what is short, medium or long range.
Smaller vehicles, like speeders, fliers bikes, tanks, or whatnot can also be approximated using these same rules. Make them smaller—a standard speeder will have 10 hit points, +7 agility, +0 sensors (which is why having robot cohort can be handy) and 1-3 slots. Small fliers and speeders will have 5 hit points, +8-9 agility, no sensors at all, and only 1 slot. While, naturally, such vehicles can't travel through space, the chase and vehicular combat rules are generic enough that you can still apply them just fine without modification.
