Air Sweeper is one of the most popular defenses in Clash of Clans.
Currently, there are seven levels available for this defense.
And, it takes quite a lot of time for a player to upgrade it as the gold cost is high and the upgrade takes a week or more than a week to complete.
It is quite common for players to forget about the upgrade cost of Air Sweeper and their corresponding upgrade time.
To solve that issue, I've come up with this article!
In this article, I've listed the upgrade cost, and upgrade time of Air Sweeper in Clash of Clans.
I've done all the math required so that you don't have to!
So, without any further ado, let's dive right into it!
Air Sweeper Upgrade Cost and Upgrade Time in Clash of Clans
I've organized the entire data in a table.
Moreover, to make sure that everything is easy to read and understand, I've also written the data in text in an organized manner.
The following table displays the upgrade cost, and upgrade time of Air Sweeper in the game:
| Air Sweeper Level | Upgrade Cost (gold) | Upgrade Time |
|---|---|---|
| 1 | 200,000 | 4 hours |
| 1 to 2 | 300,000 | 6 hours |
| 2 to 3 | 450,000 | 8 hours |
| 3 to 4 | 800,000 | 12 hours |
| 4 to 5 | 1,200,000 | 1 day |
| 5 to 6 | 1,900,000 | 2 days |
| 6 to 7 | 3,400,000 | 3 days |
The data in the above table can be interpreted as:
- You'll require 200,000 gold to build a level 1 Air Sweeper. It will be built in 4 hours.
- To upgrade a level 1 Air Sweeper to level 2, you'll need 300,000 gold. The upgrade gets completed in 6 hours.
- Upgrading a level 2 Air Sweeper to level 3 requires 450,000 gold. And, the upgrade takes 8 hours to complete.
- To upgrade an Air Sweeper from level 3 to level 4, you'll require 800,000 gold. The upgrade will take 12 hours to complete.
- Upgrading an Air Sweeper from level 4 to level 5 will require 1,200,000 gold. And, the upgrade gets completed in 1 day.
- To upgrade an Air Sweeper from level 5 to level 6, you'll require 1,900,000 gold. The upgrade will take 2 days to complete.
- To max out your Air Sweeper by upgrading it from level 6 to level 7, you will need 3,400,000 gold and 3 days of time!
Conclusion
In this article, I've listed the upgrade cost of Air Sweeper along with the corresponding upgrade time.
I'll also update the data in this article if any numbers change in the game in the future.
Also, please note: I've updated the data in this post. The entire data in this post is up-to-date as of 2 October 2025.
To max out the Air Sweeper quickly and efficiently, you should use mainly farming attack strategies to arrange for the gold required for the upgrades.
Now, I'd like to hear from you:
Have you already maxed out the Air Sweeper in your base? If not, what's the current level of the Air Sweeper?
Or, you might have a question.
