Project Payback - Hard Sci-Fi Setting

 When the stars fell from the sky over the worlds of Calliope Republic, the notion that humanity was alone in the universe shattered, and so was the notion that we would be able to work together. The interstellar war that followed killed billions, with human weaponry being unable to dent let alone scratch the invaders armor. World after world fell, until we made our last stand on the world that gave us life. While the Calliope Republic fell, her last stand brought the invasion to a halt. With the gates to Calliope severed, the last settlements became capitals for new nations, each rooted in the knowledge that the threat may return. The year is 127 PCE, and the stage is set. Welcome to Project Payback.

Setting Details

This setting is similar to Agrippa-259 in terms of its technological level and scale. There are key differences; specifically in terms of weaponry and faster than light travel.

Technology

From the modern era, Project Payback takes place 350 years from the future. The Calliope Republic itself was the known pinnacle of technology in the human world. The alien threat however is known to have better weapons and technology.

In a direct confrontation, the Calliope Republic needed five ships to engage one alien ship in a ‘fair’ fight with the threat.

Faster than Light Travel

Sprox-Gates, as they are known, connect every human colonized star system. Sprox-Gates use a material known as Sproxite (Borrowed from Greek Sproxte, ‘Push’) to manipulate spacetime, covering the ship in a transrelativistic (effectively superluminal) pocket that sends the ships to the next system. Sprox-Gates are usually three of a kind, each covering a 120 degree segment of the star system.

There are two configurations: One way and Two way assist

In a one way assist, the pocket is only given enough energy to stay stable for a short period of time. Upon collapsing, the ship is able to maneuver conventionally and usually has to use gravity assists to slow down. Invariably, one way assists are often used by pirates and smugglers who rush up to the gate and jump. A downside to one way assists is that the pocket collapsing in deep space can disable or destroy prograde and retrograde thrusters.

In a two way assist, the pocket is given enough energy to stay stable for a longer period of time, and is expected to be caught by a receiving Sprox-Gate. If not caught, the ship may exit in an unexpected area, like on the other side of the solar system or in deep space, where the ship will have to maneuver conventionally back to the solar system.

Weaponry

Ships in Project Payback eschew traditional shielding systems as they do not exist instead, they use armor plating.

Typical weapons systems found in human space.

Vessel Types

  • Ships
  • Spacecraft

Unguided Weapons Systems

  • Coilgun
  • Railgun
  • Mortar

Guided Weapons Systems

  • Missile
  • Torpedo
  • Loitering Munition (Mine)

Additionally, ships contain advanced heatsink and radiator systems to plume excess heat from weapons use. Taking out a vital radiator can lead to certain death in space. It is assumed that all ships in Project Payback have those built in by default.

Claims

Claims will consist of up to ten systems, with up to 8 habitable planets. You can have up to two partially finished megastructures. These can be from the list provided in the map thread.


Questions can be forwarded to me in this thread

if you thought this was dead, you would be wrong! I’ve been working on ships, navy stuff, all important to a hard sci fi setting

here’s a sneak peak


VESPER CLASS
AUTOMATED LONGHAUL HEAVY FREIGHTER
ORISON HEAVY FREIGHTERWORKS

When it comes to pushing pure tonnage around, the Vesper Class Automated Longhaul Heavy Freighter is the choice for many nations, corporations, and various organizations for inter-system logistics. Coming in at an impressive 550 meters long, 330 meters wide and tall, it can carry an astounding billion kilograms or three thousand standard containers. Due to its primary propulsion system being a Sequoia Type Nuclear Salt Water Rocket, it is automated, running on a program that is communicated through tightbeams. An additional constraint of the NSWR is that it cannot traverse sprox-gates on its own; it must be towed across by tugs, as the plume produced by the NSWR would irradiate surrounding traffic.

PASTEL CLASS
DIRECTED ENERGY WEAPON (DEW) FRIGATE
FORSYTHIA SHIPBUILDING CORPORATION

The Pastel Class is the newest Directed Energy Weapon Frigate in service with the Commonwealth Navy. 75 long, 25 wide and tall, it is one of the first ships in the navy to host a DEW Spinal, alongside a DRFM jamming package. A side effect of this is that it has an elevated radar signature compared to similar ships in its weight class. To compensate, it has six FEVFHR thrusters in prograde and retrograde directions, allowing for snappy attitude control.

Armor

Total Size - 2 meters

Materials - Titanium Carbide Ceramic, PBO fiber, Copper, Graphite Aerogel, Vandium-Chormium Steel, and Boron Filament.

Layer One - Anti Flash - 30cm - Titanium Carbide Ceramic

The anti-flash armor is designed to bear the immediate brunt of a nuclear blast and heat. The titanium carbide ceramics used are made in a diamond pattern that look similar to the ship’s Active Electronic Scan Array radar panels, to prevent their immediate targeting. Radiators, radar panels, and other weapon systems sit on top of the anti-flash layer, covered by a PBO spall liner.

Layer Two - Spall Liner One - 20cm - PBO fiber

The first spall liner is made of PBO fiber and is there to catch chipped pieces of anti-flash armor or canister-type munitions from damaging the stuffed whipple shield.

Layer Three - Stuffed Whipple Shield - 1m - Copper, Graphite Aerogel

The stuffed whipple shield is offset from the first Spall Liner and Bulk Armor by 25cm each. The stuffed whipple shield itself is a mix of 5cm copper plates and 5cm graphite aerogel (totaling 10 layers of copper and graphite aerogel.)

Layer Four - Bulk Armor - 30cm - Vanadium-Chromium Steel, Boron Filament

The bulk armor is made of 6cm panels of vanadium-chromium steel and boron filament. It is designed to prevent kinetic penetration of a vessel by spreading the force of impact across a shock resistant alloy (VCS) and vibration resistant filament (BF).

Layer Five - Spall Liner Two - 20cm - PBO fiber

The second spall liner is offset from the actual hull of the ship and the bulk armor by 5cm. This spall liner is there to catch spall and other hazardous items from penetrating the vessel’s hull.

Weapons

subcategory - Kinetic

2x 105mm Coilguns

These 105mm Coilguns are chopped down from heavier designs for work against near peer frigate and sloop threats. They have AP, HE, and Grapeshot Canister.

AP, HE, Grapeshot Canister

8x 56mm Autocannons

The 56mm Common Autocannon is a common weapon in the chart, with many nations using it and its associated ammo. With good accuracy and muzzle velocity, it is a reliable choice for taking out a ships radiators when paired with an accurate WSO.

shoots APHE-T, HEAT, and HE-RPF rounds

8x 35mm Chainguns

The Dual Purpose Common 35mm Chaingun is a fast, inelegant choice. They chew through unprotected ships, but are essentially useless against warship grade armor.

shoots AP and HE-RPF

subcategory - Electronic

1x DEW Spinal Laser (IR)

Fed upwards of half the ships 640 megawatt supply and set on a swivel, this DEW Spinal is a beast for intercepting both guided and unguided threats. It can also directly fire on other ships, slowly ablating the enemy ship apart.

4x DEW Lasers (IR)

These lasers are fed much less power than the DEW spinal, and are generally better at intercepting than they are fighting. They are more precise, and a WSO with a good eye can easily use them to snipe enemy radiators.

2x DRFM Jammers (Radar)

These jammers ‘catch’ radar waves and change the information, before emitting several false returns that scramble and confuse enemy radars.

Countermeasures

subcategory - Kinetic

2x Chaff/Flare Dispenser

These dispensers deploy high yield aluminum that create large radar returns that seduce active radar seekers. They also deploy flares that create high candela returns (in the millions) to seduce thermal/heat seeking missiles.

subcategory - Electronic

1x Radar Illuminator (Anti-Jam Functionality)

This piece of technology serves two very important purpose; self illumination of chaff, and increasing the range (and success) of a burnthrough sweep. The first aspect allows the ship to create a false semi-active homing track (via chaff) for semi-active radar seeking missiles to fly into. The second aspect gives the ships radar a chance to locate a jamming ship by exponentially increasing the radar return to the point of potentially nullifying a jammers effectiveness.

1x Self Project Jammer (Pulse Jamming)

This piece of technology creates a spherical shield of jamming that renders active radar seekers dead on arrival and unable to track any target.

subcategory - Other (Cyber, Information)

CIPS-45 Anti-Intursion Software

CIPS-45 AIS is a tigthbeam protector meant to stop unauthorized access from a virus, and has the ability to automatically render safe fuel systems if it believes a hostile hardware has overridden the navigational control system.
