Drops a line of bombs when crossing the Bloon track.
~ Description of the Bomber Ace in BTD6
Bomber Ace 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.
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.
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.
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.
Bomber Ace has overall been buffed since it was first released. The blast radius buff, deployment rate buff, and damage buff had allowed it to become more reliable as the Monkey Ace's primary lead-popping power as well as for countering grouped bloons. However, it has been nerfed slightly over later updates to make it less overpowered in Race Event situations.
Bomber Ace bombing run blast radius increased (25 → 35)
Bomber Ace bombing run attack cooldown reduced (3s → 1.5s)
Bomber Ace bombing run damage increased from (2 → 4)
Bomber Ace costs more ($500 → $900)
Bomber Ace bomb damage reduced (4 → 3)
Bomber Ace bombing run attack cooldown increased (1.5s → 1.7s)
Bomber Ace bombs will now benefit from the Rapid Fire crosspath.
While Pineapples are never the star of the show, the amount of pierce they have is completely unnecessary for their usage window and has only led to balance problems for Bombing Run, specifically in races. This high amount of pierce has been more evenly spread through higher tiers & crosspath. [...]

Base Bomber Ace bomb pierce decreased (40 → 20)
0-3-1 Bomber Ace bomb pierce decreased (40 → 32)
Monkey Ace was never intended to be a great starting tower and instead come into power at mid- and high-tier upgrades, but since the base tower feels lacking to new players (and some of us old timers) we decided to rework low tier power into the base tower. [...]

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.
