[Free] OSA Night Gaunt Mk1
Open Source Armada
Fighter
A experimental 6 gun stealth ship, made to target slow vulnerable civilian ships like surface miners, comes in autocannon and laser variants. //Download// https://github.com/Open-Source-Armada/OSA-Night-Gaunt-Mk1 //Specs// 6 mounted weapons with a staggered fire trigger system. Shoot_1+ and Shoot_2+ are your triggers, bind these to your weapon hotkey (space by default). Rapidfire button switches between staggered fire (gun 2 will stagger behind gun 1 creating a machine gun effect) and alpha strike (both guns fire together). BoostMin and BoostMax act as a aim keybind without yolo (yolo is avoided where possible due to the 0.2 delay) these should ALWAYS be bound to the same key. Ship is set to both fly and aim at a smooth sensitivity (tune to your taste), Boost keybind removes these limits allowing for faster pitch/yaw. This can be altered to be the more common method of aiming, having higher sense as standard, and having the ships pitch/yaw slow down for aiming. (Swap the BoostMin/BoostMax Off values with its On values, remember to set it in the pitch/yaw lever fields too) 140 m/s max speed using T2 maneuver thrusters, no trails. 354387.656 kg in weight. 3 small prop tanks for 3 million prop, 50 mins estimated flight time. 3 T1 fuel chambers + 6 T1 generators + 3 T1 enhancers gens idle at 16.7% for 7 hours 40 mins idle time, estimated flight time 4 hours 50 mins. Basic script for current Fuel/Prop times. Uses advanced FCU. //Cost// Aeg 4.1 stacks (7072 kv) Aja 2.3 stacks (3942 kv) Ark 0.1 stacks (220 kv) Bas 21.0 stacks (36362 kv) Cha 16.3 stacks (28107 kv) Exo 1.2 stacks (2140 kv) Ice 2.4 stacks (4224 kv) Kar 0.1 stacks (192 kv) Kut 0.0 stacks (43 kv) Nhu 8.1 stacks (13993 kv) Vok 24.4 stacks (42079 kv) Total ore 80.1 stacks (138375 kv) Assembly cost 59158 credits Manufacturing cost 886970 credits Total cost 946128 credits Stats based on autocannon, other versions will differ. //Tactics// Starting as an attempt at a new armoured fighter, i changed the goal when plating was not providing the needed protection i wanted. The frame was reworked into the largest amount of guns i could keep above 140 ms, without trails. Most if not all miners, haulers and any other civilian ship are unarmoured, 6 guns will make quick work of them. Most dont go max speed either, so you are not missing many targets of value. Where i believe this ship will do best is hunting surface miners, as most are slow, and are practically stationary when mining. Endos should be easy to kill with 6 guns, but remember that they can kill you too. The unarmoued hull means you are relying on gank tactics, the element of surprise is your main advantage. Dodfights should be avoided, even a tripod skiff can crit you. There is no shame in running away from a fight in this ship, you have already left honour at the door when you pilot it. I believe the hull of this ship is ripe for modification, different weapons, higher tier components, even armour and regular thrusters to convert over to the original goal.
[FREE] Puppe
Ark's Sparks
Miner
Model Number: MMESM-072A Name: Puppe Type: Basic Miner Features: - Speed: 150 m/s (dry) - Twin lasers, with convergence and auto sweep modes - 144 crates, expandable - Easy to upgrade - ISAN Mono - 2x empty medium propellant tank supports The MMESS-061A Larve's bigger brother more than doubles its crate count. It also has 2 lasers, increasing mining speed to help fill up the increased number of crates faster. It may lack a laser drill, but it is certainly still an Ark's Sparks design. If you're upgrading from a Larve and want a cost-effective ship to ply the safe zone in, you should consider this. The ship's crate count can be further increased by restructuring the beamwork around the outer crates to add crate layers, up to as many as you want. The Puppe will be available in both T1 and T2 variants, differing in thruster and generator tiers. The BP is available for free on the Ark's Sparks Discord at: https://discord.gg/WrsxUv6bwJ It can be found in the miner catalog.
[FREE] XL-1200 | XL-1452 | XF-960
Roman Shipyard
Hauler
First up is the XL-1200, a gargantuan hauler for the largest loads. Not only does it haul, it hauls FAST. Twin plasmas can move this ship up to 150 empty, 127 with random ores, (calculated as 15 tons per stack) and 107 fully loaded with lukium. (26 tons per stack) Next is the XL-1452. This is pretty much the XL-1200 but with an additional 252 crates and double the propellant tanks. This ship is more economical too, due to it only using 1 plasma it is much cheaper to construct, however it is much slower too, roughly 30-50m/s slower than the XL-1200 Lastly is the XF-960! Have you ever wanted more speed? More hauling power? Introducing the XF-960! Featuring a twin plasma setup with a whopping total of 36 rings, as well as 56 tier 3 box thrusters, this monster boasts a speed of 150m/s empty, and guess what? also 150m/s loaded, all while carrying 960 crates of ore! Speed... above all else! (Having a full 960 crate load of lukium does manage to drag it down to 146 point something according to the ship calculator here https://starbase.codes/ship_calc/ but its close enough, and id be really confused on why you would have THAT much lukium...) :P (heat updated as well) >> https://discord.gg/RarSABb3N5 <<
[Free] OSA Ghast Mk2
Open Source Armada
Multirole
Latest variant of the Ghast, now with 20 missiles for bombardment. Since its release the Ghast has been used as my test bed for missile and torp testing before committing to a specific new design. When the 5 pod launcher was finally added, they easily attached to the Ghast, and was very reliable (for missiles anyway). The default scout variant has also been updated with some of the new additions made on the launcher variant. //Download// https://github.com/Open-Source-Armada/OSA-Ghast-Mk2 //Specs// Comes unarmed for scouting or with 20 missiles for bombardment. LaunchMissile+ and LaunchTube+ are your missile triggers, bind both to the same key, this system uses no yolo and is a simple way to cycle and launch missile tubes. CenterSensePlus and CenterSenseMinus is your standard sensitivity, Adjust both to your preferred flying sensitivity. AimMax- and AimMin- is your Aim hotkey, Bind both to the same keybind, this will lower your sensitivity, Adjust MinSensePlus and MinSenseMinus to change Aim sensitivity. AimMax+ and AimMin+ is your Boost hotkey, Bind both to the same hotkey, this will raise your sensitivity, Adjust MaxSensePlus and MaxSenseMinus to change Boost sensitivity. Ship is set to both fly and aim at a smooth sensitivity (tune to your taste), Aim keybind lowers the limits for sniping, Boost keybind removes these limits allowing for faster pitch/yaw. 150 m/s max speed using T2 manoeuvre thrusters, no trails. 104255.96 kg in weight without missiles, 131225.469 kg armed with missiles. Two small prop tanks for 2 million prop, 1 hours 10 mins estimated flight time. One T1 fuel chamber + Two T1 generators, gens idle at 14.5% for 8 hours 30 mins idle time, estimated flight time 2 hours 30 mins. Basic script for current Fuel/Prop times. Uses basic FCU, roll is performed using Roll_Left and Roll_Right buttons, this is to allow fast handling by isolating the roll thrusters from the FCU/MFC. //Tactics// Despite the very hindersome bugs launchers and their munitions have, the 5 pod launcher is surprisingly reliable. Reliable enough for them to be mounted onto the cheap, fast and stealthy hull of the Ghast, making it a fun and easy way to deploy the max amount of missiles onto a target. Unfortunately all missiles/torps have a chance of failure on launch due to bugs, and the ordinance itself is well known to fail at hitting moving targets, limiting there use. Where I personally see use, even if bugs are fixed, is in station bombardment and breaching. Small or large bombers may be a key aspect to siege warfare, and thus I believe small, cheap and stealthy bombers will be very valuable in the possible future. The Ghast has excellent range for a tailless ship, and can carry all its missiles at max speed. Low tech components keep the potentially one way mission more cost effective, missiles are only cheap to a point. Could possibly be used to ambush stationary ships, like surface miners.
[Free] Haul Me Maybe
Faulty Designs
Hauler
I'd never tried CLFs and was not about to spend >500k just to experiment with them, so this is literally a one-night experiment in building a small, fast 'roid hauler. Even with a few rocks it'll still move >130m/s. Has an array of five rangefinders, four at the corners and one directly in the center, to help guide approach & capture. Also includes my [simple ISAN-based Odometer](https://github.com/faultstarbase/SimpleISANOdometer), because it's always fun to know how far you've gone. I genuinely didn't expect it to perform well but it has outperformed those expectations so considering that it might be helpful to others I decided to post it. Admittedly though it's not close to perfect & so offers the enterprising ship builder much room for improvement: for one, it does not have roll at the moment and I was way too lazy to bother tweaking it *ad infinitum* to enable it. Handles very well on all other axes, though! :wink: As the creator is incredibly lazy, the blueprint may be [downloaded immediately](https://faulty-industries.s3.us-west-1.amazonaws.com/haul_me_maybe.fbe) at no cost. For exactly the same reason, it is provided with absolutely no warranty or support. Instead, it's offered on a pay-what-you-believe-is-fair donation basis: the minimum is simply a request to send a message to the creator (`Fault` in-game or `Fault#9610` on Discord) if you end up printing & enjoying the ship. Live long & prosper.

Sturgeon E6

The ETS-03B Sturgeon E6 is a luxury station hopper for when you want to travel in style around a station. The enclosed cockpit is accessed through a door on the bottom, while the carapace-style plating on the center folds open like reversed butterfly wing doors to allow 6 endos access to its passenger compartment. The passenger compartment has wide glass windows on the sides, as well as a glass floor. A unique feature of this ship is its pop-out fuel chambers in the rear of the ship. While it has 2 fuel chambers, only 1 is in use at any time. This is toggled automatically depending on if the fuel chamber is popped out or if the fuel rod within is empty. If the rod is empty, the fuel chamber will also slide out automatically. The ship is fully plated in Ajatite to conserve weight. Travel in style, travel in a Sturgeon. **WARNING:** Due to moving parts carrying vital machinery, it is highly recommended to stick around nearby when it is outside so that it doesn't change hosts. Changing hosts has a chance of bugging out moving parts. This is a strictly non-combat ship.
