The Athena Cannon is an artillery unit unique to the United States, which relays a target for the Mercury satellite to strike with a powerful laser attack.


One of the more interesting concepts to be fleshed out in the United States' arsenal is the Athena Cannon. A large but fragile vehicle, it uses highly advanced communications devices to connect with the Mercury Satellite, providing it with information about enemy positions so that the orbital weapon can adjust to the new coordinates and unleash a powerful orbital laser strike.

In comparison to the Mercury Strike controlled through the primary Uplink structure, the more precise coordinates set thanks to the use of Athenas helps focus the firepower of the Mercury's laser beam, allowing the satellite to deal more damage to enemy structures. However, the radius of such attack is smaller than the one Allied commanders can order via the control building. Nevertheless, while the power of an Athena-controlled Mercury attack is great, it might be tricky to use against moving objects due to activation lag.

The Athena Cannon's activation lag is a short pre-firing delay due to the need to re-calibrate the satellite's position and angle in order to fire. More importantly, if a Mercury Strike has previously been called down in the vicinity of an Athena Cannon's current position, their attack power will further be increased for a short while.



  • The Athena Cannon first appears in Ghost Hunt, and is unlocked to the player once the Research Dome is captured from Scorpion Cell forces. If the Research Dome is lost, access to the unit will be lost as well.


  • Very effective against structures.
  • Decent against groups of infantry and light units.
  • Can safely destroy most defensive structures from a long range.
  • Deals area damage in a small target area.
  • Using Mercury Strike nearby can temporarily increase its firepower.

  • Quite expensive ($1650).
  • Slow-moving.
  • Not very durable.
  • Vulnerable to aerial and anti-armor threats.
  • Exploitable minimum range.
  • Laser beam has activation delay, which makes it difficult to hit moving units.


The Athena Cannon uses the voiceset of the same unit in Red Alert 3.

  • The name and idea were based off the Athena cannon from Red Alert 3.
  • In 3.0, the Athena Cannon was known as the Basswave, which fires sonic blasts instead. It was changed due to the inclusion of Haihead's Shadray.
  • Azri_Apoc is credited as the voxel artist for Athena Cannon.
