Things could get interesting down the road a few years hence. I always wondered what would come after a “Z” model.
Sadly, the Zulu Cobra is the last of the H-1 line, along with the sister ship, the UH-1Y. Apart from relatively minor upgrades to improve each model, the H-1 will take its place in history after their time is up. Unless, of course, the Marines decide to extend the service life ;<)
