#TravellerRPG Tech – Beams & Missiles & Casters, oh my!

In Classic Traveller RPG and the more recent Cepheus Engine implementation of the rules spacecraft weapons generally are either Missile or Beam (lasers, particle beams, fusion beams). In Traveller 5 another class of weapons, Data Broadcasts or Beamcasts, is introduced. As advanced as Traveller technology is, it appears that Humaniti is too inventive.

In February 2019, the Defense Intelligence Agency published Challenges to Security in Space. This volume is part of their Military Power Publications. As befits an intelligence agency, the focus is on, well, the threat:

Space-based capabilities provide integral support to military, commercial, and civilian applications. Longstanding technological and cost barriers to space are falling, enabling more countries and commercial firms to participate in satellite construction, space launch, space exploration, and human spaceflight. Although these advancements are creating new opportunities, new risks for space-enabled services have emerged. Having seen the benefits of space-enabled operations, some foreign governments are developing capabilities that threaten others’ ability to use space. (Executive Summary)

One graphic in particular stood out to me; it concerns Kinetic Energy and Orbital Threats:

In Traveller RPG terms, Kinetic Energy Threats are covered by Missiles. However, several of the Orbital Threats shown are not immediately represented in Traveller or Cepheus Engine.

Lasers, KKVs, and Robotic Mechanisms are easily portrayed using the existing Traveller or Cepheus Engine rule set. Using Traveller 5 one can get to Radiofrequency Jammers using Datacasters.

High-power Microwaves is not easily found in the rules. This weapon is maybe a form of an EMP device:

The electromagnetic pulse (EMP) weapon, also called the e-bomb, or the radio flash weapon, is capable of disrupting or damaging the circuitry of most electronic devices.

The weapon accomplishes this by sending either a single pulse or a series of fast, high-powered pulses of electromagnetic energy in the range of 100 MHz to 20 GHz. These pulses are similar to a lightening strike or a nuclear blast. The power level of these pulses can be several hundred megawatts (MW). The EMP weapon has a range of at least several hundred meters, but reportedly can be transmitted up to 15 Km.

The specific method by which the pulse attaches to the circuitry is called coupling. Coupling is simply the binding of an energy wave onto a conductor. There are two types of coupling. The first is called front door coupling and it happens when the energy wave binds to the antenna of a device. The other type is called back door coupling. It occurs when the wave binds to external components such telephone lines, network cables and power lines.

It can also occur with ports on the back of a computer, such as serial ports. After the energy binds, it then moves through the circuitry, frying or disrupting sensitive internal components, such as crystal diodes, ICs, mixers, logic circuits, etc.

The precise targeting of electronic devices can be accomplished in the following way: First the EMP weapon can be aimed in a specific area. The primary factor is not the power of the pulse, but the ability to focus the output. The energy must be accurately deposited at a certain range to be effective.

Next, it can be configured to send a single pulse consisting of a specific frequency, which will only destroy the circuitry of a device that functions on that frequency. In this manner, if an operator has the frequency signature of a target device, then only that single device will be affected, while others in the area remain unharmed.

Furthermore, a series of fast pulses consisting of multiple frequencies can be sent to an area, which will affect the circuitry of all devices operating on those frequencies. This type of delivery is referred to as an ultra wideband pulse (UWBP). It can be adjusted to cover large areas, even an entire city. (newworldwar.org)

In Traveller/Cepheus Engine terms this sounds like a weapon that can be used to destroy sensors or otherwise fry circuits. At higher Tech Levels, the EMP pulse could even be tailored to attack specific components of a ship.

Chemical Sprayers looks interesting. Even spraying something as simple as water in space may create ice that could be lethal at high velocities. Or maybe its chemicals to coat optics or smear solar cells? Other sci-fi ideas may be a chemical that eats at door seals (depressurization?). Maybe what we have here is an early form of the Sandcaster?

Of course, the lowest-tech solutions are also effective. Where in Traveller was there ever harpoons in space?
