Does extra damage. Can place other Monkeys on the upper decks of the ship, increases attack speed of all water based Monkeys.
Carrier Flagship is the final upgrade of Path 1 for the Monkey Buccaneer in BTD6. It deals extra damage, as well as increasing attack speed of all water-based towers by ~18%, and in addition, it grants two new small platforms that grant bypassing of Line of Sight limits for monkeys placed on them. The planes will now fire only one rapid stream of darts, although they have increased pierce (+5 per dart, 14 pierce per dart overall), damage (+1 per dart) and will aim at bloons rather than firing forward. Darts from Carrier Flagship planes can pop Lead Bloons. It costs $21,250 on Easy, $25,000 on Medium, $27,000 on Hard and $30,000 on Impoppable.
Avoid placing the Flagship too far upward on the screen, or else there is no room for the towers to placed on.
Since Carrier Flagships cannot be moved by Support Chinooks, it is important to place the Flagship somewhere other towers don't need to be placed.
The Carrier Flagship is extremely useful on maps with large amounts of water due to its ability to increase attack speed of all water placed towers.
The best towers to be placed on Carrier Flagship platforms are Snipers, as they are entirely unaffected by Line of Sight upon placement on such high ground, as they don't have visible projectiles that may accidentally hit obstacles, which otherwise would destroy the projectiles.
Using towers with a small footprint (Snipers, Dart Monkey, etc.) it is possible to fit up to 4 towers on the platforms in total with pinpoint pixel perfect positioning.
Though the Carrier Flagship allows towers placed on platforms to see over obstacles, it does not allow their projectiles to pass over obstacles, meaning they will collide and not deal any damage. This is probably a bug.
Due to a bug relating to the property that any towers placed on top of the Carrier being able to see over obstacles, any tower placed on top that is then moved off via a Support Chinook is able to see through obstacles even when they are on the ground.
When being cross-pathed, upgraded to Grape Shot, Hot Shot, Longer Range or Crows Nest, the planes will reset and will appear to come out of the flagship once more. This may be detrimental if the Flagship is a major part of the player's defense.
As with Aircraft Carrier, when looked closely the Carrier Flagship also shoots its original Destroyer attack.
It also will shoot grapes too if Path 2 upgrades are added, but it's easily noticeable.
