Air Defender · build 22791246 · published
This is a major update bringing enemy variety, a comprehensive intelligence reporting system, an expanded Guide panel, intercept status updates, shift handover, supply coaching, and dozens of fixes across interceptors, radar, voice, and training.
Enemy aircraft now employ a wider range of deception tactics. What you see on your radar may not be what it appears. Intelligence reports from various sources across the UK will help you identify threats -- pay attention to the clues. Difficulty setting affects how challenging these encounters are to detect.
The ASMA console now posts intelligent, data-driven reports from across the UK.
- Real Aircraft Data: Every observer report -- RAF veterans, air cadets, coastguard, police, North Sea oil rig crews, ATC squadrons, GCHQ -- references the contact's actual altitude, speed, heading, and approach direction. Reports never contradict your radar picture.
- Expertise-Aware Language: RAF veterans use proper military terminology. Civilians describe what they see. Air cadets check their Jane's guides. The source shapes how it's written.
- Contact Positions: Every report includes where the contact is (e.g., "30nm north of Edinburgh"), so you can correlate sightings with tracks.
- ATC Call Intelligence: CALL ATC now includes a RELATED INTELLIGENCE section -- observer sightings, SIGINT assessments, registry checks, and ATC anomalies for the queried track.
- Your Squadron: 849 real RAF Air Cadet squadron numbers and locations across 34 Wings are included. When an enemy aircraft overflies your town, your squadron may be the one to spot it.
- Radar-Gated IDO: The Identification Officer only reports contacts visible on the radar scope. Aircraft beyond coverage are reported by maritime and ground observers, not the IDO.
The Guide panel has expanded from 9 to 12 tabs with comprehensive coverage of game mechanics.
- Overview: Game setting, your role as an Air Defender, the core control loop, and what difficulty affects.
- Scoring: Score meter rules and key scoring mechanics.
- QRA Operations: Scramble procedure, the 4-minute delay, fuel states, how to task a tanker, and RTB.
- ROE: Mission-based weapon authorisation rules, tension state rules of engagement (Peacetime, Heightened, Critical) with the current state highlighted, aspect gating, kill probabilities, ROE violations, and the full escalation sequence -- written in plain operational English.
- Procedures: Reorganised into 7 named scenario types for clearer reference.
- Opens on Overview by Default.
At the start of a new session, some IFR civilian contacts are pre-classified as Assumed Friendly by the previous watch, reducing initial identification workload.
Right-click an interceptor and select STATUS to get a mission update: current phase, bearing and range to target, and fuel state -- posted to the ASMA console with voice comms.
- Low Ordnance Coaching: When weapons run low at a base, the ASMA console now coaches you to dispatch a supply mission. The NO ORDNANCE warning also includes this hint.
- Redeploy Missile Count: When redeploying combat aircraft, destination bases now show their current missile count with colour coding (green = can arm a pair, yellow = can arm one, red = insufficient).
- Track Classifications Persist: Your identification work -- Hostile, Suspect, Unknown, Assumed Friendly, X-ray, Zombie -- now survives saving and loading. Previously all classifications were lost on reload.
- Weapon Indicators: Interceptor tracks now show G for guns, R for radar-guided missiles, and H for heat-seeking missiles (e.g. G180/R4/H2). Clearer at a glance.
- Panel Resize from Top: All panels can now be resized by dragging their top border. Side and bottom drag margins are also slightly wider for easier selection.
- Spoofer Cover Integrity: Spoofers now keep their civilian cover presentation much more consistently until visual identification, making deception play out more convincingly on the scope and in Flight Info.
- Military Filter Gating: Enemy-looking contacts no longer leak into the Military filter before you have genuine identification grounds to treat them as military.
- Readable Radar Symbology: Compact labels, leaders, hook boxes, origin circles, and radar/L11 history dots have all been tightened up for a clearer and more stable radar picture across zoom levels.
- Civilian Traffic Recovery: Atlantic and Scottish north-west civilian IFR routes now stay visibly populated, keeping the wider air picture healthier during longer sessions.
- Local Observer Coverage: Local intelligence reports now surface more reliably when unidentified enemy aircraft overfly the UK, with stronger regional coverage and better source variety.
- Show Of Force Presentation: Show of force now reads as a much clearer visible manoeuvre instead of feeling like an invisible state change in the intercept flow.
- Tanker Recovery Flexibility: Tankers returning home can now still be redirected into tanker-to-tanker refuelling before landing starts, then continue their recovery afterwards.
- Interceptor Track Continuity: Friendly interceptor tracks now stay visible more reliably during airborne refuel and RTB transition periods instead of briefly dropping off the scope.
- FIR Escalation Procedure: The complete escalation sequence (escort, show of presence, show of force, turn-away warning) now works correctly for all enemy types approaching the UK. Pilot reports "aircraft not compliant" at the correct time during the procedure.
- Easter Egg Aircraft: Hidden aircraft unlocked through Operation Silent Bunny now carry correct weapons loadouts and can be used as fully combat-capable interceptors.
- QRA Launch Cancellation: Pending QRA launches can now be cancelled during the scramble countdown.
- Escalation Completion: QRA interceptors no longer get stuck after completing the full escalation sequence against Suspect targets. Interceptors now correctly resume shadow or escort formation.
- Visual Identification: QRA interceptors assigned to intercept Suspect contacts now properly complete visual identification before engaging in Critical tension.
- RTB Speed: QRA interceptors on return to base now respect Buster, Cruise, and Eco speed settings from the right-click menu.
- Engage Orders: QRA engage orders no longer refuse when retasking to the same target.
- Refuel from CAP: QRA interceptors ordered to refuel while on CAP now correctly leave the patrol pattern and proceed to the tanker.
- Identify Completion: QRA interceptors on Identify missions no longer immediately return to base after identification. They now continue shadowing the target, allowing the normal intercept and escalation procedure to proceed.
- Redeployed Interceptors: Redeployed interceptors no longer return to base immediately on launch.
- Subsonic Speed Limits: Subsonic interceptors no longer exceed their maximum speed when tasked to engage fast targets.
- 4-Ship Radio Calls: In 4-ship launch groups, duplicate radio calls and voice gaps during the escalation sequence are now resolved.
- Track Designation Persistence: Track designations (Suspect, Hostile, Unknown, etc.) now persist when tracks drop off and reappear on radar.
- Civilian Aircraft Names: Civilian aircraft now display their actual aircraft type name (e.g. Boeing 737, BAe Jetstream 41) instead of a generic classification.
- Missile Track Cleanup: Missile tracks disappear immediately from the radar display after a confirmed kill.
- Bomber Track Freeze: Enemy bomber tracks no longer freeze on the radar display when a radar station is toggled off and on.
- Multiple SEAD Tracks: Multiple SEAD aircraft now appear as separate tracks instead of one flickering track.
- Hidden Aircraft Tracks: Hidden aircraft tracks now behave like normal radar tracks and carry the correct weapons loadout.
- Scroll Stability: The ASMA console no longer snaps scroll to top when new messages arrive.
- Visual ID Spam: VISUAL ID messages no longer repeat excessively during civilian identification.
- Sortie Tabs: Sortie tabs now correctly disappear when flights land and recover at base.
- Premature Identity: Aircraft identity is no longer revealed prematurely in ASMA messages before visual identification has been completed.
- INTEL Filter Tab: GCHQ assessments and SIGINT reports no longer appear in the Aircraft filter tab.
- Emergency Squawk Codes: Emergency squawk codes (7700, 7500, 7600) now persist for the full duration of the emergency instead of being replaced after a few seconds.
- Weapons Controller RTB Response: The Weapons Controller "copied RTB, base is BRA" response now only plays when the pilot initiates RTB, not when the Weapons Controller ordered it.
- FIR Escalation Voice: FIR escalation voice calls now work correctly for all approach directions.
- Training Audio: Training intro voice now stops immediately when clicking Back from the selection screen.
- Training Progress Recovery: Training progress now automatically recovers when switching between Proton or Wine compatibility layers on Linux.
- Window Resizing and Panning: Window resizing and mouse panning now work correctly on Linux (Wayland).
- Regional Clock: The regional clock now appears reliably on every game start via Linux/Proton.
- Keyboard Hotkeys: All keyboard hotkeys (F-keys, time controls, numpad, Tab cycling) now work reliably on Linux and Wayland systems.
