I wonder whether it would be possible to get details of the available missiles in-game.
A way would be to add the site layout that is currently in the manuals also as screen in-game, and the missile launchers may have the equipped missile and the linked channel as mouse-over pop-up information.

Oh, and I love spreadsheets - I'd love to have a spreadsheet of all the missiles with their different characteristics, range, speed, altitude, power-up time, time till overheating, .... Offline, of course, as a separate part of the documentation...
