Fighter Plane is the third upgrade in Path 1 for the Monkey Ace in BTD6. In addition to increasing its flight speed, it shoots 2 powerful seeking missiles at MOAB-class Bloons, inflicting 18 damage each to up to 4 bloons each (6 with Exploding Pineapple). These anti-MOAB missiles attack every 4.0s and only trigger if MOAB-class bloons are on screen.
Fighter Plane is a good option for handling early MOAB-class bloons by regularly shooting anti-MOAB missiles. They are not as efficient as MOAB Maulers, but they have the advantage of infinite range that MOAB Maulers lack while still not requiring ability use.
Fighter Plane can be used to break open the layers of early MOABs. To optimize it fully, however, micromanagement with adjusting Ace targeting should be done to make better use of its darts.
There are many advantages of Fighter Plane when compared to the MOAB Mauler. Fighter Plane is able to shoot seeking anti-MOAB missiles at any distance without Line of Sight problems, despite not being very effective against grouped MOAB-class and being only a few hundred dollars more expensive.
It should be noted that the anti-MOAB missiles are shot every 4.0s. This is a lot slower than a MOAB Mauler, and its single-target blimp damage is rather low.
When calculated, the Fighter Plane's missile DPS versus MOAB-class is 9 compared to 22.22 for MOAB Maulers.
Fighter Plane has overall been nerfed since it was first released, mainly to counteract its efficiency versus single-target MOABs versus MOAB Mauler before it was nerfed.
Fighter Plane missile rate reduced from 3 to 4 seconds.
Fighter Plane missile pierce increased from 1 to 3.
However if there are no M.O.A.B. Class Bloons and the missiles are shot out, they will keep circling around and eventually disappear.
The Fighter Plane's pilot actually wears the goggles on its woolen hat.
The only Tier 3 Monkey Ace upgrade to only have a front propeller as the plane's driving force is the Fighter Plane. Bomber Ace swaps the front propeller for two side propellers, while Neva-Miss Targeting adds two jet engines alongside retaining the front propeller.
Before Version 17.0, one Fighter Plane is almost always able to break open the outer Fortified MOAB layer of the Round 40 Fortified MOAB in Alternate Bloons Rounds, though it needs additional assistance to pop the Fortified Ceramic children efficiently since it cannot defeat the Fortified Ceramics by itself.
