Is this a bug?

I unlocked the nuclear missile launcher module that was for cruisers. I tried to select different cruiser chassis and none of them had the nuc missile launcher appear anywhere?! what’s going?!? it says its unlocked but it wont appear.

If you have the Order DLC installed, it should show up when you change your race from Federation to Order.
It is a weapon exclusively for that race.

Thanks for your help!
