Bloons Wiki

Adds a powerful cannon that shoots out powerful bombs.
~ In-game description

Cannon Ship is the third upgrade of Path 2 for the Monkey Buccaneer in Bloons TD 6. It replaces its ordinary dart attack with a powerful independent cannonball attack that shoots exploding frag bombs, producing 8 fragments per explosion once detonated, much like Bomb Shooter's Frag Bombs. Explosions deal one damage and pop up to 28 bloons (35 with 0-3-1) per shot within a blast radius of 40. Fragments deal 1 damage each, and they pop up to 1 bloon each, 2 with 0-3-1. Cannon Ship shoots bombs every 1.3s, and shoots faster with Faster Shooting's +33% attack speed (every 0.975s). Additionally, its hot burning grapes (from the Hot Shot upgrade) deal 2 damage each. Like all Buccaneer upgrades, the ship can shoot cannonballs both forwards and backwards if it detects bloons behind it.

Unlike BTD5, the Cannon Ship does not have automatic camo detection because Crow's Nest is now a Path 3 upgrade.

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

Cannon Ship

Cannon Ship upgrades the ship by adding a mast and sail, modifying its bow into a pointy shape, and adding a raised quarter deck. The monkey now gains an eyepatch on its left eye and a pirate hook on its right hand, in addition to having its usual pirate hat. Inside the ship's deck is a load of cannonballs. In the upgrade portrait, the pirate monkey squints his eyes and pointing his glistening hook forwards, and smiles as if to say "Arrgh!". His smile also shows off his golden tooth.

The upgrade portrait of Cannon Ship is slightly erroneous. The Buccaneer in the artwork has its hook on its left arm instead of its right. The monkey's eyepatch covers its right eye instead of its left eye as it does in-game.

Cannon Ship replaces darts with an independent cannon ship attack, which shoots bombs that release 8 sharp fragments upon exploding. Fragments pop up to 1 bloon each (2 with 0-3-1), and cannot shotgun its parent bloon, in the same way that Frag Bombs operates. Additionally, the Hot Shot grape attack deals 2 damage instead of 1.

Targeting Priorities[]

Cannon Ship targets bloons using the standard target priorities. It has multiple types of attacks that are shot in different styles. It can also utilize multiple targeting to shoot projectiles from both ends of the boat if it detects bloons on its opposite side.

  • First: Targets the first bloon visible within its range.
  • Last: Targets the last bloon visible within its range.
  • Close: Targets the closest bloon visible within its range.
  • Strong: Targets the strongest bloon visible within its range.

Grapes are straightforwardly projectiles shot in an angular spray, and bombs are also straightforwardly projectiles shot in an angular spray.

If given the Crow's Nest upgrade, all its attacks can prioritize Camo Bloons over other types, which is provided by the Camo Prioritization targeting.

Cannon Ship is a low-price upgrade for the Monkey Buccaneer designed primarily for adding extra grouped bloon popping power. It is normally bought as a stepping stone towards Monkey Pirates, but it has one important niche in Race Events in the form of a 2-3-0 ship for more popping power from a 0-1-0 Buccaneer. It is a smart choice to try to make use of its double cannon attack by letting shoot in both directions, making full use of its cheap cost-effective group-popping power.


  • Crosspaths impact the optimization of the Cannon Ship's power. Generally speaking, 2-3-0 offers a greater DPS in general by increasing rate of attack plus extra +1 grapes per shot, whereas 0-3-2 offers more pierce and innate camo detection. 2-3-0 offers extra grapes and faster cannon attacks. The 0-3-2, however, has the advantage of increased pierce and camo detection for all its attacks.
    • A 0-3-2 Cannon Ship can work great in Alternate Bloons Rounds, thanks to Long Range buffing the pierce of grapes and bombs, and providing reliable early game camo. It can also be later upgraded to 0-4-2 to trivialize Round 40 and 60, and generally decrease the amount of fortified BFBs.
  • Although Hot Shot already provides lead-popping power for the Buccaneer, the Cannon Ship upgrade can be used to provide extra popping power versus grouped bloons. Its group-popping prowess excels against 30's bloon rounds such as Round 37 and Round 39 when crosspathed optimally. Monkey Pirates also offers even more grouped popping power.
  • For better performance, place the Cannon Ship such that it is able to shoot from both sides.

Version History[]

Balance Changes[]

Although the Cannon Ship attacks were not changed at all throughout the history of BTD6, the grape attacks were buffed when interacting with Double Shot and Long Range. These are both significant changes in Race Event scenarios, as the extra grapes packed extra popping power for the 2-3-0 Cannon Ship and 0-3-2 Cannon Ship.

  • BUFF Affected by 2-1-0 Grape Shot double grapes buff.
  • BUFF Affected by 0-1-1 Grape Shot +1 pierce buff
We wanted to do a little general lower tier balancing of costs, as things work a bit better at higher tiers but on the lower end with T1-2 upgrades cost for power doesn’t compare well. We’ve realized that the 130 crosspath just hasn’t even been working for cannons, so we wanted to correct this so that people get all that they pay for with that crosspath, however middle path buccaneer at higher tiers has been overperforming significantly so in addition to this attack speed buff we have also balanced back out that difference in the opposite direction with a damage reduction.
~ Ninja Kiwi
  • BUFF 1-3-0 Cannon Ship now reduces attack cooldown of the cannon by a 0.75x multiplier
  • BUFF Affected by Hot Shot DoT buff
Small tweaks to Buccaneer’s Long Range upgrade to improve its additional pierce benefit for a number of attacks.
~ Ninja Kiwi
  • BUFF 0-3-1 Cannon Ship now gains +7 pierce to bombs (28 → 35) and +1 pierce to fragments (1 → 2)
[...] As noted earlier, Middle Path was identified as not having weakness to justify the power and is seeing changes related to that.
~ Ninja Kiwi
  • NERF Cannon Ship's frags attack interaction changed from Burst to Shrapnel (i.e. frags spawned from the cannon bombs no longer targets the parent bloon)
Middle path buccaneer continues to attack with its initial 1 damage projectile that never gets upgraded but the Cannons are very much intended to be a ‘replacement’ upgrade to this main attack, so we are finally disabling that dart along with improving the damage of grapes for the T3 & T4 on this path so the lower tiers can save into Pirate Lord better
~ Ninja Kiwi
  • NERF Cannon Ship now disables the dart attack
  • BUFF Cannon Ship grape damage increased from 1 to 2

Bug Fixes and General Changes[]

Extra Notes (Version History)[]


Official artwork[]



  • One 0-3-0 Cannon Ship costs exactly the same amount as the equivalent non-crosspathed Cannon Ship in BTD5 Flash. This is because the Grape Shot upgrade costs $50 more in BTD6, the Hot Shot upgrade replacing the upgrade where Crow's Nest was costs $250 more, but the Cannon Ship upgrade itself costs $300 less than in BTD5.
  • Cannon Ship is the only Path 2 Buccaneer upgrade where upgrading it along Path 1 also changes the color of the rims of its cannon barrels. This is likely an unintentional change, as the color of them are supposed to be for Long Range instead.
