LINUX AIR COMBAT is a free, open-source combat flight simulator for the LINUX community. Its roots came from the well-known "classic" flight game known as "GL-117", but this new incarnation has been extensively re-written and improved.  This is now the world's leading open-source combat flight simulator for Linux.

LINUX AIR COMBAT is also known as "LAC"

  • Innovative "Network Router Panel" on cockpit shows network telemetry and comms data flow from other players
  • Best-of-breed network user management with inter-player status messages on the cockpit panel
  • Powerful integration with "Mumble" for world-class voice communication between players
  • Dedicated Mumble server manages a rich hierarchy of voice radio channels and online help
  • Automated radio messages verbalize enemy airfield status when Mumble Radio is properly tune
  • 23 Comms-related functions can be mapped to any keyboard key
  • Text-only, low-bandwidth comms option acts like a "Morse Code" radio, generating and decoding real Morse code
  • Airfields with defensive guns challenge nearby opponents and protect nearby allied aircraft

  • Damaged airfield defenses are gradually repaired by surviving airfield maintenance personnel
  • Air raid sirens blare loud on damaged airfields
  • Bombers have auto-gunners that take shots at nearby hostile fighters
  • "Norden" bombsight emulation makes precision, medium or high altitude bombing possible
  • Realistic bomber climb rates:  Heavily loaded bombers need a long time to climb to altitudes high enough to avoid fighters
  • Realistic bomb-run tactics make heavy bombers vulnerable to opposing fighters during critical mission segments
  • Heavy bombers can destroy an airfield in a single sortie if well flown and undamaged by opposing fighters
  • Real-time, automated radio and RADAR warnings alert players when their airfields are threatened by strategic bombers
  • Online users can choose their own unique "CommunityHandle" name, and see the names of other players
