Floater Bug

The Floater Bug Aliens appear in the 2012 movie American Warships. They are cockroach-like aliens capable of hovering and are armed with a trigger-less flamethrower that launches radioactive fire balls. Using wreckage from sunken ships, they use a stealth ship with an LCD screen for camouflage armed with EMP missiles. The aliens thrive in radioactive environments and have a set of jaws on their abdomen that can chomp a human in half with little effort and have an exoskeleton strong enough to survive bazooka shells. They were eventually defeated by the crew of the USS Iowa.
