Lock On: Modern Air Combat or LOMAC, known in Russia as Lock On, is a modern combat flight simulator developed by Eagle Dynamics and published by Ubi Soft in Europe and 1C Company in Russia; it is considered as a survey simulator by its creators. It contains 8 flyable aircraft and over 40 non-playable/AI-controlled planes. The game mainly revolves around air-to-air combat and air-to-ground combat with some optional, unique roles such as pinpoint/anti-radiation strikes, anti-ship strikes or aerobatics. The game realistically models all aspects of take-off and landing, AWACS (also known as AEW&C), carrier-based landings (for the Su-33), and aerial refueling.
LockOn: Flaming Cliffs 2 is a further evolution of LockOn: Flaming Cliffs. All of the player-controlled aircraft have been transferred to the virtual environment created for the Digital Combat Simulator series.
In November 2009 Eagle Dynamics announced that a paid upgrade called Flaming Cliffs 2.0 was planned for release in early 2010.
