Time to revisit (again).
What does hawk do that isn't done better by swift, mobile GtA, or statics?
Particularly swifts and to a lesser extent statics, since someone with access to hawks definitely has access to these other options.
Swift is faster, has immortality boost protocol paired with burst (combo much), are cheaper making them more accessible when you need them, are better at intercepting, and lack the weakness that hawks have in lack of maneuverability.
Hawks have a higher hp/cost and dps/cost, but won't make attrition against swifts until the density where their dps will kill swifts before they can boost away. Swifts are still better at moving through opposing territory because boost makes them immune to an entire area's AA.
Hawks are supposed to be better vs. gunships, but they generally die to tridents of equal cost (and this can snowball very quickly), and lose to the GS units like banshee and rapier if the opponent is microing around them (especially rapier who can slow them for additional positioning advantage). Swift can fire their missiles from outside of the range of either unit, making them able to kite them with some effort, which the hawk cannot do.
Hawks can tank hits for other planes a bit better depending on what opposing fire is (since boost will prevent attrition due to dps). They can also DPS krows which is a big deal.
The only time hawk is better is when you have a crap ton of them, and for that level of investment you can get screamer/chainsaw/mass razor which are blatantly more efficient. The mobility is sort of nil unless the map is huge since aa range is big and you don't want to contest the air in opposing territory anyway.
Agree/disagree?
