@ Coyote, this may help you with answers to what you will most likely be seeing long run @ least as far as helicopters go in this mod. Also if you look at the wiki link the planned replacement for the law is... the nlaw.

@ Khaki. The ch-148 will not be replacing the griffon, the ch-148 is a shipboard helicopter intended to be operated for the Navy by the air force. It says so in the wiki article you linked. As the sole pilot for the 1CPB at this time(we are recruiting). Having spoken with O'Hally and asked him his plans in regards to future aircraft content as of this post the most likely helicopter you will see is the CH-147 @ some point. There are no immediate plans for fixed wing support because the f-35 is in flux and the other three contenders for cf-188's remain unknown to me.
