How do the defensive features (e.g. shields, armor, countermeasures) of the Hawk compare to other light fighters such as the Gladius, Mustang Delta, and Defender?

Anvil designed the Hawk, so as you'd expect it's reasonably durable, at least as light fighters go. In this respect we plan for it to have tougher armor than the Gladius, Mustang Delta, and the Defender. Its shield generators are presently intended to be similar in performance to those of a Gladius. While the Hawk carries on more armor, the Mustang Delta's defenses include a larger store of countermeasures.
