Sapphire

Sapphires are heavy fighters with projectile swarms.

Properties
Sapphire fires two homing boomerangs at a constant rate at enemy ships or structures.

Strategies

 * Try not to use Sapphire directly due to its high launch cost. Instead, use fleet carriers to offset the launch cost, because carriers can create Sapphires at square rate, while the Fighter Bay and Fighter Yard create them at a linear rate.
 * If you're going to use Sapphires, make sure you escort them with Falcon or Rapier to counter anti-fighter ships.
 * EMP Rounds on Sapphire make extra-short work of shields, as its damage will be boosted to 9, 9 and have 27 damage per second.
 * Sapphire Hangar on Jupiter or Legion can easily overwhelm heavy Phalanx defenses, even though Phalanx counters projectiles.

Trivia

 * In reality, Sapphires are gemstones, commonly associated to be blue. The real reason why they're blue is actually because of impurities within the sapphire itself.
