Project: Air System
by pycodder
Project: Air System is a NeoForge 1.21.1 mod for ground-based air defence and an air raid alarm, with drone and aircraft models for the air picture.
What it does
The mod adds unmanned aircraft such as Shahed delta drones, Lancet, Orlan, PD-2 and S-70 types, flying wings with turbojets, and an air drone object managed by DroneFlightManager. Drones are entities, and their speed, ceiling, toughness and warhead differ by type. Models are built from the vanilla ModelPart system with an animated renderer, so they show detail such as sensors, lens windows, elevons, navigation lights and landing gear.
On the defence side the mod adds ground blocks with block entities: a Gepard tracked SPAAG with twin 35 mm guns and two radars, a Slinger compact remote weapon station with a 30 mm gun, a Terrahawk Paladin unit with a radar that scans a full circle, a MANTIS unmanned auto air defence system, and a 35 mm revolver cannon pedestal. An alarm loudspeaker can be heard over 160 blocks, and an air raid button raises the alert sounds and then the all-clear. The mod is open source under the GNU General Public License v3.0 or later.
Works with TACZ as an optional soft dependency. NeoForge is the only required dependency, and the mod runs with or without TACZ.
