Project AirSystem

A NeoForge 1.21.1 mod about the air picture: twenty unmanned aircraft, an air raid alarm system and four anti-aircraft gun mounts. TACZ is supported as a soft dependency — the mod runs with or without it.

Start here

  • Crafting — every recipe, and what an aircraft actually costs.
  • Flying a Drone — from placing the aircraft to landing it again.
  • Drones — all twenty types with their performance.
  • Air Defence — the guns, IFF and how automatic fire misses.
  • Air Raid Alarm — loudspeakers, buttons and the linking cable.

What makes it different

Drones are not entities. In the air a drone is an object inside DroneFlightManager, synced to clients through its own compact payloads; on the ground it is a block. Range therefore does not depend on the entity tracking radius, and a drone can operate thousands of blocks from its operator. The reasoning is in How It Works.

Everything is generated. Models, textures and sounds are produced from scratch by the scripts in tools/. No sampled audio, no third-party assets. Engine sound is synthesised from a physical model — firing pulses through exhaust resonances for a two-stroke, a compressor buzz-saw for the jet — and the game adds Doppler shift and rpm lag on top, so a drone passing overhead drops in pitch the way a real one does.

The prototypes are recognisable. Each airframe follows the real aircraft's planform: a Shahed is a delta with a straight trailing edge and fins on the tips, a Lancet is a tube with two X wings, an Orlan carries its tail on a boom.
