Spaceships Missiles by Weight

In this post I discussed how much damage guns in spaceships should do. Its seen a fair amount of traffic, and I find myself constantly going back to it. The post generally comes to the conclusion that the damage for a given caliber and the ammunition weight is correct, but that the size of the weapon and its amount of ammunition is off, and suggests buying guns and ammunition by weight. While analyzing missiles is much more complex (and something I keep on putting off), we can use the same assumptions spaceships did to buy missiles and their launchers in the same fashion. These are the two principles:

• Missiles weigh twice as much per shot as kinetic weapons do, and do the same damage
  
• Missile launchers weigh the same as a gun firing a projectile half the size

These are rough approximations, but they give consistent results within the spaceships system. I'm using it for my current game, and the numbers seem to work out. I hope you find it useful as well!

Robots as Spaceships: Coms and Sensors

Back when we were nitpicking the gun-bot, we took a look at its comms and sensors.  We found that the comms were very good, but that was tempered by the assumption that the spaceship would be using them in space. We also found that its sensors were quite lack-luster.

Review: Nightreign

I was really excited to see Infinite Worlds: Nightreign come out. I bought it the first day, and read it quickly. It was not what I was expecting. It was, however, a good Gurps book.

The Gunbot Mark II

We started robots as spaceships with the gunbot, a simple robot intended to serve as the baseline for our exploration of building robots as spaceships. Now, I'm playing a game where I want a simple trackbot as the basic foe. Robots as Spaceships feels roughly complete at this point, and I present to you our new robot: 

A Fishing Boat using Spaceships

In one of my games it turns out I need a boat for crossing back and forth in the North Atlantic. I've done a lot of work in spaceships, so I figured I build the boat using spaceships and the alternate spaceships options from pyramid #3/34.

Vehicle	ST/HP	Hnd/SR	HT	Move	Lwt	Load	SM	Occ	DR	Range	Cost
Oceanic Fishing Boat	200	0/4	13	.5/14	30 tons	9 tons	SM+5	2+6	15 DR	3640	$183K

The ship is a 30-ton hull. Its systems are: 1 combustion engine, 1 screw propeller, 2 fuel tanks, 3 steel armor, 1 control system, 1 engine room, 3 systems that combine to make a single SM+6 habitat system with two bunk rooms lacking life support, 3 more combined habitat systems forming a freezer, and 6 cargo. 

I bumped up the DR from 10 to 15. If you look at the armor table for steel alloys, you'll see why: it follows the standard range table progression until it drops from 2 strait to 1. Since we are using DR instead of dDR, I figured 15 was appropriate. I don't foresee the boat being shot at too much... but then again, it probably will pick up at least one bullet hole somehow. If we are worried about this, we can justify raising the armor by 5 using deflection boost.

Double checking our boat against the Nordhavn 40, a few things stand out. Our price is a little cheaper, from the single boat I found for sale, but its within about 20%, which is a lot farther off than we could have been. The speed is way too high, which doesn't surprise me, as spaceships often gives generous performance numbers. In play I'll probably be using the 7 knot speed of the comparison boat. As for the other numbers... They're harder to find, which is why I used the spaceships design system rather than digging around for proper stats on trawlers. 

Its nice to have this tool available. There are surprisingly few ships statted out in gurps, so I'm posting this in hopes someone will find it useful.

Robots as Spaceships: Small Armor Table

I've been calculating armor values for small spaceships for a while now, and its quite doable, but its a bit tedious, and if an error is made it can be difficult to catch. So I've build a page of armor values for small spaceships. I'm looking forward to being able to reference it. The image below is for reference: if you text you can interact with, highlight, copy, and so on, click here.

 

The DR given is the amount of DR per system of armor. Each system of armor is 1/20th of the total weight.

The weights follow the size/range table, which gives us three divisions in each size modifier. For more stats on spaceships of that weight, see Between SM's. 

The TL number is given because its useful when working with the "Boost" numbers for adjusting armor, also explaining the example armors that go up to a theoretical TL 15. The numbers I find myself checking the most are 6, which is basic Steel and thus the cheapest option, and 13, which is "Awesome Future Armor" in TL 10, which seems to be a great spot for Battlesuits and general space opera. 

I hope you find this table useful, and I hope you enjoy your robots!

Robots as Spaceships: Paver-Guard Battlesuits

On the rim of civilized space, there are monsters. Alien beasts of every description imaginable. Some are hostile and irritable. Some are fearless and stealthy predators. Some are driven by strange hive-mind bent on destroying human habitation. Don't rely on exterminators to keep you safe. They will avenge you, but if you want to stay safe, you'll need Armor. Armor like PaverGaurd. 

I've talked about creating power suits and walkers in earlier posts, but I really only made one. Here I present a spectrum of TL 10 battlesuits of all sizes.
