AirHeX

A turn-based hex wargame about the one thing most air-combat games skip: energy.

Altitude and speed are your only currency. Turn hard and you bleed speed.
Dive and you buy it back. Climb above your enemy and you decide when the fight happens.
The rules are built from real performance curves, and the historical doctrines emerge on
their own: don't turn with a Zero, boom-and-zoom in a Mustang, keep your corner speed.

What's in this prototype

• Simultaneous plotting. Both sides commit their manoeuvres in secret, then the turn
  resolves at once. The pilot with more energy gets to peek and adjust one step of the
  flight path — throttle and altitude are already committed. Advantage becomes information.
• Flights, not just duels. Multi-aircraft engagements with wingmen on both sides.
  Formations, mutual support and getting separated all matter.
• Aircraft as data. The initial roster is the A6M2 Zero, P-51D Mustang, Bf 109 G-6 and
  Spitfire Mk.IX, each with its own energy profile. Every aircraft is a single data file
  with cited sources, so the roster will grow — and so can yours, if you want to add your own.
• Two fighting doctrines — turn-fighter and boom-and-zoom — plus a wingman that flies to
  hold station rather than to win. Checked by running thousands of engagements against each
  other: over 1,000 duels each against a Zero, the Mustang wins 67% flying boom-and-zoom and
  34% flying as a turn-fighter. The aeroplane wins by not turning, and loses when it does.
• Spectator mode. Watch AI pilots fight. Every engagement is different.
• Wings (training mode). Raise a cadet over twelve weeks and send them into combat.
  Two courses: the crew room, where you play poker between sorties on the days nobody
  flies, and the classroom, where you pick the week's subject off the blackboard, fly
  the drill, and answer for yourself when something happens. Spend what you earn on
  Gunnery, Handling, Agility and Stamina. Whoever comes out goes on the roster and can be
  flown in the simulation.

Who this is for

If you liked hex-and-counter air games like Flight Leader or Fighting Wings, or wondered why
nobody made a proper digital successor to Achtung Spitfire — this is an attempt.

Feedback wanted

Does the energy game feel right? Is the AI flying like a pilot or like a script?
Which aircraft should come next? Leave a comment — the numbers are all in JSON and
I'd love to hear where they're wrong.

Running it

Windows, Linux and macOS. The macOS build is universal (Intel and Apple Silicon) and is
signed ad-hoc, so the first launch needs right-click → Open.

第二次大戦の戦闘機による、エネルギー機動を核にしたターン制ヘクス空戦ゲームです。
高度と速度だけが資源で、旋回すれば速度を失い、降下すれば取り戻す。
実機の性能曲線から起こしたルールの上で、「零戦と旋回戦をするな」「P-51は一撃離脱」
といった史実の教義が自然に最適解として現れます。

• 秘密同時プロット制。エネルギー優位側だけが相手の機動を見て、飛行経路を1手だけ修正できます（スロットルと高度は先に確定していて動かせません）
• 1対1だけでなく、僚機を含む多対多の編隊戦に対応
• 初期の機体は零戦21型・P-51D・Bf109G-6・スピットファイアMk.IX。機体は1機＝1つの出典付きJSONなので、今後追加していきます（自分で足すことも可能）
• 旋回戦型・一撃離脱型の2種のAIと、勝つためではなく位置を保つために飛ぶ僚機。数千戦の統計で確認済み——対零戦で各1,000戦、P-51は一撃離脱で勝率67%、旋回戦では34%
• AI同士の空戦を観戦するモード
• 育成モード「ウイングス」：12週で候補生を育てて送り出します。課程は2つ。飛べない日に卓で札を配る待機所と、黒板の課目を自分で選んで教練を飛び、出来事に自分で答える教室。得た点は射撃・操縦・敏捷・体力に振ります。出てきた搭乗員は名簿に載り、シミュレーションで飛ばせます

Windows・Linux・macOS。macOS 版はユニバーサル（Intel と Apple Silicon）で、
