Your Role
You are the Controller of RAF No. 11 Group Operations Room at RAF Uxbridge, August–September 1940. The Battle of Britain is at its height. Luftwaffe raids are crossing the Channel daily — your job is to detect, intercept, and destroy them before they reach their targets.
You do not fly. You command. Every squadron scramble, every vector, every decision about when to hold back and when to commit — that is yours.
The Operations Room
Left Panel
Today's operations summary, campaign totals, weather, force readiness stocks, and the R/T radio chatter log.
Centre Map
The plotting table. Hostile raids appear as red tokens; your squadrons as yellow. Click any token to open its tasking panel.
Right Panel
The Tote Board — real-time state of every squadron in 11 Group. Lamp colours show readiness from AVAILABLE through to REFUELLING.
Sector Clock
The 12-hour clock top-right. Colours rotate every 30 minutes — yellow, red, blue — so plotters know the age of each map token at a glance.
Raid Detection
Chain Home radar detects incoming raids as they form up over France. An alert card appears showing estimated strength, altitude, and approach corridor. You have minutes — sometimes seconds — to decide whether to scramble.
⚠Watch for POSSIBLE DIVERSION alerts. The Luftwaffe frequently sends a feint to draw your squadrons out of position before the main strike follows. Do not over-commit to a small plot.
Scrambling Squadrons
Click an incoming raid token on the map, then click SCRAMBLE in the tasking panel. The closest available squadron is pre-selected. You may select any number:
SelectionEffect
1 squadronStandard intercept. Economical — preserves reserve.
2 squadronsStronger intercept. Better against large raids.
3+ squadronsBig Wing. Maximum force — but exhausts multiple squadrons simultaneously. Dangerous if a follow-up arrives.
💡Squadrons must be AVAILABLE (green on the Tote Board) to scramble. A refuelling squadron cannot respond when the next wave arrives.
Tote Board — Squadron States
AVAILABLEOn the ground, fully ready. Can be scrambled immediately.
SCRAMBLEDAirborne and climbing. Not yet in contact with the enemy.
AIRBORNEIn the air — patrolling, rebasing, or returning.
ENGAGINGIn combat with the enemy. Cannot be reassigned.
LANDINGReturning to base. Out of the fight temporarily.
REFUELLINGOn the ground, rearming and refuelling. Not yet available.
Engagement Cards
When a squadron makes contact with a raid, an Engagement Card appears. It shows enemy composition, RAF squadrons engaged, a live R/T ticker with tally-ho calls and combat reports, loss bars, and an outcome banner when the engagement resolves. Cards auto-dismiss after the time configured in ⚙ Settings, or close manually with ×.
The Enemy — Luftwaffe AI
The Luftwaffe operates across four escalating campaign phases and adapts to your responses:
- Phase 1 — Radar: Probing raids against Chain Home stations to degrade your early warning.
- Phase 2 — Airfields: Sustained attacks on sector stations to break command and control.
- Phase 3 — Sector Ops: Deeper penetrations targeting operations rooms and supporting airfields.
- Phase 4 — London: Strategic bombing of the capital begins.
The AI remembers which corridors suffer heavy losses and avoids them. If you respond quickly, it may launch diversionary raids to draw your squadrons out of position.
⚡Goering's Interventions — directive flashes from Karinhall represent the historical interference of the Reichsmarschall. They change enemy behaviour immediately and unpredictably.
Airfield Damage & Relocation
Bombers that reach their targets cause cumulative damage shown as pulsing markers on the map. Above 75% damage a sector airfield becomes unserviceable and based squadrons relocate automatically. Damage repairs slowly overnight. Losing Chain Home stations degrades early warning — raids appear closer to the coast with less reaction time.
Named Historical Raids
On certain calendar dates the simulation triggers scripted historical engagements — Eagle Day (13 Aug), The Hardest Day (15 & 18 Aug), the first mass raid on London (7 Sep), and Battle of Britain Day (15 Sep). A banner announces the event with historical context and the AI adjusts to match the intensity of that day.
Victory & Defeat
There is no single victory condition — the Battle of Britain was a campaign of attrition. You are assessed at the end of each day:
Daily AssessmentVerdict

Kill ratio 2:1, limited damageFavourable Result

Kill ratio below 1:1 or heavy infrastructure lossCritical Situation
The campaign continues until the Luftwaffe's combat effectiveness collapses below 30% — or until your sector system breaks.
