Project AirSystem 1.0.0

First release. Twenty unmanned aircraft, an air raid alarm system and four anti-aircraft gun mounts for NeoForge 1.21.1.

Full documentation is in the wiki — start with Crafting and Flying a Drone.

Requirements

Minecraft	1.21.1
Loader	NeoForge 21.1.209 or newer
Java	21
Optional	TACZ — bullets and ammunition are recognised automatically

What is in it

Twenty aircraft in three roles. Loitering munitions dive onto a target and detonate; reconnaissance types loiter and come home; strike carriers release a guided bomb and return. Each airframe follows the planform of the real aircraft, and performance — speed, ceiling, toughness, warhead — differs from type to type.

Four gun mounts. Gepard, Slinger, Terrahawk Paladin and MANTIS. Three can be crewed or left on automatic; MANTIS only ever runs itself. Automatic mounts identify friendlies by launch point and never engage a drone launched within 70 blocks of them, and their fire genuinely misses — hit chance falls off with range and target speed, and a failed roll walks the burst wide.

Air raid alarm. Loudspeakers audible over 160 blocks, buttons, and a linking cable to bind them. The siren is synthesised as an electromechanical siren — a rotor chopping air through stator ports, shaped by a horn — not as a tone.

Operation from a remote. Mark a target on the world map, launch, then fly by hand or let the autopilot work. A flight can also be launched with no target at all: the aircraft takes off and is handed straight to you.

Notable details

• Engine sound carries live Doppler shift and rpm lag, so a pass overhead drops in pitch the way a real one does.
• The vanilla explosion is replaced entirely: staged flash, fireball, ground dust wave and smoke column, with the report arriving late by the speed of sound.
• Where you hit a drone matters — centre, engine bay or wing are told apart.
• Every model, texture and sound is generated from scratch by the scripts in tools/. No sampled audio, no third-party assets.

Known limitations

• Drones are not entities. That is what gives them unlimited range and low server cost, but it also means mods that act on entities will not see them: entity radars, entity-based protection and third-party anti-air will not detect a drone. Explosion-based protection still works.
• Crafting does not vary by type. Every aircraft uses the same recipe with either a warhead or a camera module, so a Shahed-238 costs the same as a KUB-BLA. Server owners who want the heavy types rarer should edit the recipes.
• Tested in single-player and on a dedicated server; no compatibility testing against large modpacks yet.

Configuration

Everything is in config/airsystem-common.toml — flight time, cruise altitude, chunk loading radius, IFF radius, automatic hit chance, alarm duration, and switches for glass breaking and fires. See Configuration.
