Bomber Ace

"Drops a line of bombs when crossing the Bloon track."

- Description of the Bomber Ace in BTD6

 is the third upgrade of Path 2 for the Monkey Ace. It allows the Monkey Ace to drop an array of four powerful tightly-packed bombs if the Ace is near the track, while each bomb deals 3 damage on up to 20 bloons per bomb (32 with 0-3-1 or 0-3-2), and each bomb has an explosion radius of 35 (just over a 0-0-0 Dart Monkey's range). This quad bomb array has 1.36s cooldown per salvo.

It costs $765 on Easy, $900 on Medium, $970 on Hard, and $1,080 on Impoppable.

Summary
Bomber Ace is built as an upgrade for handling large groups of bloons within a tight region. When placed along a location where it can fly above a maximal amount of track, it becomes a good option for wiping out dense groups of regular bloons. It still requires support from other towers, as its bombs are still somewhat unreliable due to their random nature, but the increased deployment rate and explosion damage makes the Bomber Ace a far more reliable option compared to Exploding Pineapple.

Tips

 * Each bomb explodes immediately after the other, resulting in four quick explosions.
 * Note that the bombs cannot pop Black Bloons or Zebra Bloons, so adding other towers to assist the popping of Black Bloons and Zebra Bloons will help make it easier for the Bomber Ace to finish off the other bloons.
 * The Wingmonkey Monkey Knowledge makes the Bomber Ace much more effective, as it guarantees more hits on bloons.
 * When it comes to crosspathing, 1-3-0 is more effective in most cases, as it deploys bombs at a faster rate, allowing for more opportunity to apply bombs as it crosses over paths. 0-3-1 is helpful, but Bomber Ace bomb arrays have good pierce anyway. Tier 2 crosspaths are not very effective except in special situations.
 * Arguably, a 0-3-2 Bomber Ace is better than a 2-3-0 Ace on Park Path due to it being able to bomb the whole outer curve with the centered path flight path. This is also the case in Balance as it can bomb the outer loop of the track.
 * Even after the Version 22.0 pierce nerf to the bombs, Bomber Ace is a very popular option in Race Events due to its high pierce versus cost ratio, even if it means the bombing timing can be slightly RNG.

Trivia

 * Bomber Ace was one the few Tier 3 upgrades in BTD6 that was cheaper than the base tower. This was no longer the case after Bomber Ace received mechanics buffs followed by a price nerf both on the Version 7.0 update.
 * In the Version 7.0 patch notes, there was no mention of a price nerf to Bomber Ace in spite of it gaining a significant damage output rework.
 * In BTD6, Bomber Ace is the only Tier 3 Monkey Ace to lose its front propeller.
 * Starting from Version 30.0, the Bomber Ace upgrade has the highest percentage price gap between its Tier 3 and Tier 4 upgrades, as Ground Zero got nerfed in price. Before then, that reign belonged to Cleansing Foam. This price gap between the two upgrades is 20x, compared to 16.87x from Cleansing Foam to Overclock.
 * Before Bomber Ace was secretly nerfed to $900 and Ground Zero was $14,000, both assuming Medium prices, such price gap was 28x.
