The effect of the ability doesn't exactly double the range of every Bomb Tower in the game; instead it only increases the range of up to 10 of them, like the Super Monkey Fan Club.
Long reach bomb towers from tier 4 Bombing Range. Note ability can be activated multiple times
Trivia[]
Despite being a Specialty Building, the Bombing Range, like the Mortar Emplacement, does not include an actual building unlike other Specialty Buildings.
The third tier of Bombing Range has no additional advantage over second tier for Bomb Towers with the Bloon Impact upgrade.
There is a shattered Lead Bloon where the scorch mark is.
The fourth upgrade used to stack with other abilities in an old version, meaning you could give your bomb towers infinite range. The projectile can only travel so far, however.
The 4th tier ability is available for each bomb tower, allowing permanent range boost with enough towers.
