Hello, I have been experiencing this behavior for a while. The nuke launcher will open, it will make the alarm noise, it will sit there for a moment in firing position, and then retract. No nuke leaves the launcher and it repeats the behavior shortly afterwards. Essentially, Aeon are incapable of launching nukes.
I did a search and found nothing on the forum so either the search tool is poor or nobody has experienced this and reported anything. Sorian AI, of all other races, are capable of firing their nukes. It does this on any map, and really makes things too easy when the enemy is Aeon.
Mods I usually run are: BlackOps ACU Upgrades, Nvidia Fix, and 2x Resources.
Thanks for reading.
