our CH-53s are decades old G models and need replacement. two options were the CH-53K and CH-47F Block II, latter was chosen due to lower cost + interoperability with allies, who use the Chinook way more (only the USMC uses the CH-53).
i love the CH-53 tho, they used to be stationed on an airfield close by my grandparents' house, me and my brother always got excited when we were children and they flew over my grandparents' garden.
