The Sweeper is a mobile anti-air hovercraft that's perfect for taking out light aircraft over the sea and land, while enjoying immunity to torpedoes. It even has built-in low-range sonar!

Combine it with other units to provide some needed air defense, especially vs. the dreaded Shuriken.

It's quite expensive and not the strongest for its role, though, so try not to build more than you need.
