Overview[]

The F-51 Hell Fire is the third helicopter introduced in Battle Nations, and is the Tier 7 reward of the 6th Boss Strike, Evaline Acehart's Airstrike.

Its first attack, Scorched Earth, is a powerful Damage fire-type damage attack targeting ground units in a unique pattern. It is 25% armor piercing and has a 70% chance of added StatusEffect-fire Damage-over-Time for 3 turns.

The second attack, Deep Flame, targets an entire column of ground units dealing moderate Damage fire-type damage. This attack has a slightly lower chance of adding StatusEffect-fire Damage-over-Time (60%) and only lasts for 2 turns.

The third attack, Targeted Attack, is a typical anti-air attack dealing Damage piercing damage to an enemy Air unit.

    Trivia[]

    • This unit looks similar to a CH-47 Chinook helicopter with flamethrowers attached to the sides.
    • The F-51 designation may refer to the P-51 Mustang, a fighter airplane. It is interesting to note that the P-51, once the US Army Air Force became the US Air Force, became the F-51.
    • The Hell Fire name may be a reference to the AGM-114 Hellfire anti-tank missile.
    • There is a book known as Fahrenheit 451, 'F-51' may be a joke of the the pronunciation of 451, "Four-Fifty-One".
