Introducing Polymorphics opened new possibilities for the engineers, since their machines no longer had to be rigid. The Obliterator was among the most successful polymorphic designs. Equipped with highly sophisticated AI integrated with a human crew, these bombers resembled huge creatures rather than machines, with their gently flapping sides and majestic bearingt which earned them the title of "whales of war". Although they specialized in bombardment, Obliterators were reasonably efficient with defending themselves from air attack, using secondary beam weapons and missiles to shoot down incoming objects at an amazing rate.
