The Mastadon Cruiser is a UEF naval unit. It is designed as a naval support unit, equipped with long-range tactical missiles, extensive radar and sonar, powerful anti-air weapons, tactical missile defense (when researched) and short-range cannons for use in naval battles. However, the cruiser is only a naval support unit, so sending a fleet of cruisers unprotected leaves them vulnerable to other naval vessels, especially submarines. Its tactical missile launchers have a tendency to miss when shelling patrolling naval units. The Mastadon, especially when compared to the Poseidon, has very good anti-air, so they are good for providing anti-air support for your fleet.


  • Use large numbers of these to hide behind the thick armor of battleships and rain missiles on bases.
  • They are fairly fragile but can destroy large amounts of air units quickly.
  • With their long-range tactical missiles, Mastadon Cruisers have a range equal to Poseidon Battleships. They excel at early game harassment, especially if the opponent has not built a sufficient amount of anti-missile defenses.
  • Mastadons do not have torpedo tubes, use this to your advantage when facing them.
  • While their bombardment capabilities are great with its tactical missiles, its ship to ship capabilities are terrible. Three bombarding Mastadons, lacking upgrades, can quickly be taken out by a single moving Salem Class Destroyer. When upgraded with Stacked Gauss Cannon this problem somewhat goes away.
  • Mastadons are at their best when they are paired with Poseidons, as the Poseidons take out ships, while the Mastadons take out air.
  • when bombarding a base with TMLs its missiles are vunreble to anti-missiles
