It's not like the Soviets cared that much about Intellectual Property.
- This is the reason for the complete non-appearence of Caitlin (they never met her) as well as the "The FIRM"/The Company" difference.
- Archangel says early on that his deal with Hawke is the only way the Firm can avoid red tape and political hot water while using Airwolf, possibly referencing the senator's summation at Red Star that developing weapons like Airwolf isn't in the Firm's job description. Zeus seems to have stopped caring when Airwolf 2 rolls off the assembly line, for all the good it did.
- The fact that Airwolf is sometimes in danger of being discovered by people with less resources than Archangel means the two aren't mutually exclusive; presumably Archangel would have no trouble gaining use of the satellite that scoured the entire country for Airwolf's hiding spot, for example, without warning Hawke about like he did when someone else was using it, but he would gain nothing from doing so.
