Air Defender Changelog - Version 0.7.0.0 - 23 May 2026
A major reliability and polish update covering interceptor behaviour, voice and radio procedure, save and load, map settings, scoring, civilian and emergency handling, and difficulty options.
New: Difficulty-Scaled Fuel Consumption
[p align="start"]Interceptor fuel burn now adapts to your selected difficulty setting.Hard: Realistic period-accurate baseline (unchanged).
Normal: Half rate — interceptor sortie endurance doubles.
Easy: One-tenth rate — extended endurance for relaxed sessions.
Warnings Unchanged: Joker, Bingo, PAN-PAN and MAYDAY warnings still trigger at the same fuel percentages — they just take proportionally longer to reach.
Save & Load Reliability
Saves Survive Process Kill: Saves are now written safely — closing the game (or losing power) part-way through a save no longer leaves a corrupted file behind. The previous slot's contents remain intact until the new save is fully written.
Rapid SAVE Click Safety: Clicking SAVE rapidly no longer risks two saves overwriting each other.
Corrupted Save Entries Visible in Load Menu: Saves with malformed files no longer silently disappear from the Load Game list — they are shown with an error indicator so you can spot them and choose to delete.
Save Game Click Reliability: Loading a save no longer silent-fails when the on-disk filename differs from the in-game display name.
Mid-Mission State Preservation: Save/load now correctly preserves a wide range of mid-flight state: AWACS approach gates, tanker fuel-flow rates, Nimrod departure-leg sequencing, enemy aircraft RTB position, enemy bomber turn state and evasion timers, in-flight missile guidance parameters, nuclear weapon damage profiles, and many smaller details that previously reset to defaults on load.
Chinook Supply Missions Survive Save/Load: In-flight Chinook HC2 supply aircraft no longer disappear seconds after loading a save — cargo, ordnance, and origin-base accounting are all preserved.
Crash Sequence No Longer Loops On Load: Loading a save taken at the exact moment an interceptor was crashing from fuel exhaustion no longer re-fires the MAYDAY voice and squawk 7700 repeatedly after restoring.
Save List Loads Faster: Browsing the Load Game menu with many save slots is now noticeably faster — the menu reads just enough of each file to show its summary instead of parsing the whole save.
QRA Interceptor
Drop Tanks for Tornado F3 & Phantom FGR.2: External fuel tanks are now correctly accounted for in the fuel display and burn rate calculations for these aircraft. Sortie endurance now matches the period-accurate published figures.
Military Fuel Realism Pass: Military aircraft fuel burn rates and tank capacities have been reviewed and corrected against published 1998-era figures across the fleet.
Aircraft Fuel Burn Time-Scaling: Aircraft fuel burn now scales correctly with the in-game time-acceleration setting — running at 5x no longer leaves aircraft burning fuel as if at 1x.
Fuel Display Consistency: The Active Operations panel and the radar track block now show the same fuel percentage for the same aircraft (previously could disagree by 25%+ for Tornado F3).
Wingman No Longer Flies On At Zero Fuel: A surviving wingman of a QRA pair whose lead aircraft has crashed will now correctly declare emergency and divert/eject instead of continuing to fly indefinitely on empty tanks.
Wingman Spawns With Correct Fuel: A wingman scrambled in a CAP pair no longer joins at a stale fuel percentage from a previous sortie.
Solo Sortie Voice Calls: Solo single-ship sorties (no wingman) now hear the full controller AAR (refuelling) voice exchange that paired sorties always did.
Defender Retask Cascade: Manually retasking an interceptor against an inbound shooter now reliably brings the paired mate along too, instead of occasionally leaving them on the wrong target.
Force-Intercept on Low Fuel: Manually retasking an interceptor back onto a hostile after a tanker request has appeared no longer makes the sortie flicker between target and tanker, loop SHOW OF PRESENCE voice, and stack repeated voice rows in ASMA. The auto-divert now correctly recognises your commit-despite-low-fuel choice and stays out of the way until the target changes, the aircraft RTBs, or fuel reaches BINGO emergency.
Track Visibility During Intercept: Some interceptor tracks could drift out of view on the radar display during the intercept procedure — all friendly interceptor tracks now remain visible at all times.
Voice & Intercept Procedure
JUDY Loop Fix: Identifying a civilian after Controller-Confirm tasking no longer causes the JUDY / Controller-confirm voice exchange to loop indefinitely.
Pilot JUDY Timing: The pilot JUDY call no longer fires at scramble time — it correctly fires only when the interceptor reaches radar contact range with the target, which also resolves the duplicated controller "Copy Judy" voice and a premature RTB on civilian intercepts.
ASMA Brevity Expansion: ASMA console messages no longer show duplicated brevity phrasing — JUDY and similar military brevity codes display the expanded explanation exactly once.
Single Voice Source: The pilot JUDY voice and the matching ASMA log entry are now produced from a single source, so they no longer occasionally fire twice when different parts of the game briefly disagreed about who should speak.
Splash Voice Improvements: Splash calls at kill sites no longer report the same target as splashed twice, and the "shooter unknown" case now correctly identifies the shooter where possible.
Splash Per-Channel Exclusivity: Kill-confirmation voice ("splash") now only plays for the sortie currently selected on the radio panel. Other sorties' kills no longer bleed into your audio when you are focused on a different sortie.
Sortie Radio Continuity: Sortie radio comms no longer drop in and out during phase transitions like a tanker rendezvous. The pilot's "vector to tanker" request, the controller's bearing/range response, and the pilot's "proceed to tanker" call now play as a single continuous exchange without silence gaps.
Channel Switch Voice Resumption: Switching the radio panel from a QRA or AWACS sortie to a CAP pair and back no longer leaves you in silence — the original sortie's voice exchanges resume cleanly on switch-back, without bleeding across channels.
Pilot Mayday on Every Emergency: Interceptor pilot mayday announcements now fire correctly for every emergency, not just fuel exhaustion. The pilot's "{callsign} mayday mayday mayday" call is heard first, followed by the controller's response — matching standard radio procedure for scenario-driven emergencies, save/load-restored emergencies, and squawk overrides.
Controller Replies Stripped of Pilot Prefix: Controller-side emergency-airfield replies no longer accidentally prefix themselves with the pilot's callsign.
BRA Channel Cleanup: BRA (Bearing-Range-Aspect) callouts no longer continue to play on a sortie channel after that sortie has been cleared or retasked.
Post-Retask Voice on Repeat Missions: Post-compliance pilot voice ("aircraft now complying", "roger RTB") now plays correctly after retasking the same QRA sortie to a second target of the same type.
Intercept Progression After JUDY: Intercepts now reliably progress through the full procedure (escort, show of presence, show of force, turn-away warning) after the pilot's JUDY call. Previously the procedure could stall silently with the interceptor sitting alongside the target indefinitely — the full sequence now fires through to completion.
Suspect-Mark Pursuit Fix: Marking a contact as Suspect via the ident bar no longer leaves the QRA interceptor unable to close — speeding up, then slowing down, never catching the target — with the escalation procedure stuck. The interceptor now settles into formation and the full escalation runs end to end.
Decision Dialog Safety Timeout: Decision dialogs that were waiting on something that never arrived can no longer hold the intercept indefinitely — a safety timeout now releases the dialog so the procedure proceeds.
Civilian Emergencies
Emergency Squawks Persist: Emergency squawks (7700 / 7600 / 7500) on civilian aircraft now correctly persist instead of being overwritten by routine controller squawk reassignment.
Correct Procedure for Each Emergency: Civilian emergency intercepts now play the correct voice procedure for the declared emergency type instead of occasionally playing the wrong one.
Emergency Aircraft Identity Preserved: Civilian aircraft with declared emergencies (7500 / 7600) are no longer automatically reclassified to Hostile during intercept.
Procedure Safety Timeouts: Civilian emergency intercept procedures now have safety timeouts so the procedure cannot stall silently waiting for a condition that never arrives.
Active Ops Emergency Row Clears: The Active Operations emergency row no longer stays yellow / red after the emergency has resolved.
Map & Map Overlays
AARA and Danger Overlays Persist: Player choices for AARA and Danger area overlays now persist across in-app menu cycles, matching the airfield, city, strategic, and navaid overlays.
Saved Map View Restored: Returning to the map after a menu cycle no longer clobbers the saved zoom and pan position.
Coastline Visibility on Intel Graphics: The UK map coastline is now reliably visible on systems with Intel integrated GPUs that previously showed a blank background.
Map Display Toggles Saved: Player choices for which map feature categories are visible now persist across sessions.
Russian Deception & Enemy AI
Campaign Continuity Across Saves: Campaign waves now continue to arrive correctly after a save/load mid-campaign, and campaign victory is correctly detected when you have completed the objective.
Civilian Callsign Sync: Civilian aircraft callsigns now stay in sync across all panels — previously some civilian aircraft could show one callsign on the track block and a different one in Flight Info after loading a save.
Civilian Route Restoration: Stationary civilian aircraft, and civilian aircraft with broken or empty routes, now correctly restore on save/load instead of teleporting or hanging in place.
Hostile Cruise Missile Kill Not Penalised: Shooting down an inbound hostile cruise missile no longer triggers the civilian-kill penalty.
Hostile Aircraft Type Hidden Until ID: The Flight Info panel TYPE field no longer leaks the real aircraft type for unidentified hostiles. The TYPE field is blank until the contact is positively identified.
Disguised Aircraft Save/Load Stability: Disguised aircraft tracks no longer flicker in and out of view after save/load.
Visual ID Updates Every Panel: When interceptors visually identify a disguised contact, the revealed type now appears on the track label, the Flight Info panel, and the Aircraft Info tab consistently — no more contradictory readings between panels.
Aircraft Type Display Consistency: The aircraft type now displays the same value across the Flight Info panel, the radar track block, and the ASMA console.
Post-Compliance Turn-Away: Compliant disguised aircraft now turn away on a bearing that actually exits UK airspace from inland positions instead of pointing back over the country.
Show of Force Maneuver Reliability: The show-of-force cross-ahead maneuver now executes consistently on repeat missions, with both voice and maneuver firing together rather than the maneuver dropping silently.
Scoring & Stats
Enemy + Civilian Destroyed Counts Persist: The aggregate destroyed counts shown after a session now survive save/load correctly.
Mid-Campaign State Survives Save/Load: Your campaign progress no longer carries over to unrelated saves, and loading a mid-campaign save no longer resets your progress to the start of the campaign.
Map Content & UI
Keyboard Shortcuts Respect Typing: Hotkeys no longer fire while you are typing in a text field (e.g. the save-game dialog), eliminating the rare bug where the map could pan autonomously after using Ctrl+A in a dialog.
Aircraft Data Tab Updates Live: The Aircraft Data tab on the flight-plan track popup now updates within half a second of a positive identification instead of lagging by several seconds.
Track List Panel Stability: Track List panel no longer briefly flashes errors or fails to draw in unusual configurations.
Tanker Callsign Consistency: Tanker callsigns now display the same value across the Track List, the on-map track block, and the Active Operations panel.
Flight Info Panel Polish: Various Flight Info panel display improvements (TYPE hiding for unknown hostiles, callsign formatting, and status accuracy at mid-mission states).
