"The Battle Blimp bypasses ground-based obstacles and delivers your Clan Castle troops directly into the heart of the enemy village, all while dropping bombs along the way. However, its thin hide makes it easier to shoot down. Immune to spell effects."
The Battle Blimp is the second Siege Machine you unlock, available when the Workshop is upgraded to level 2.
The Battle Blimp prioritizes the Town Hall over all other targets, and will fly over all other types of enemy buildings and troops to reach its location, regardless of whether or not the Town Hall is still standing. When the Battle Blimp successfully reaches the Town Hall (or its remains), it automatically breaks apart to reveal the Clan Castle troops inside.
Initially, the Battle Blimp is a red blimp reinforced with spiked metal reinforcement on the front and back. It has a wooden propeller on the back and wooden boxes on the side.
At level two, wooden boards are attached to the sides of the blimp. The front of the blimp gains added metal reinforcements.
At level three, each wooden board is replaced by a metal plate. More metal reinforcement appears just above the nose of the blimp.
