+1 on the Dolphin. Was hoping to see it for the BHaH2 update, especially with the DID campaign entering 1918.

2000 produced, 2 squadrons operating it in Feb of 1918 and another 2 by March 1918

Snipe by contrast had 497 produced and entered service in September of 1918.

Having said all that, I can only imagine the hundreds of hours necessary to make a new AC.
