The wealth issue is currently under control through both research into better TN wealth generation, more TN industry (which is taxable, unlike conventional), and appointing a governor who improves wealth generation.
Armature
... son of a <naughty word>. No, while the army likes its electrical dynamo coils, it mostly focuses on production of Armigers... because its damn hard to find a word for a big stompy 'Mech that isn't already used somewhere else. (And I know Armiger is also used by WH40K, but at least its a sub-class of a type of stompy robot instead of being a catchall like BattleMech, Wanzer, Titan, Mobile Suit, Gundam, etc.)
Updated all references that I could catch.
Shipyards
Well, in the eternal struggle between the army and navy for who gets the most funding, they were cashing in on the threat of aliens descending unchecked on Earth. Well, there have been no aliens in nearly two decades, but that doesn't stop the Navy from planning light escorts and dreaming of cruiser classes.
The Tekko is terrible
Agreed - its simply a sad reality of size-1 missiles that if you need half the weight to generate a usable explosion, its going to be slow. The Kingdom is working on fixing the issue - which has the happy benefit of making its offensive missiles and torpedos better as well.
The Ruins of Sol
The Kingdom will be able to begin clearing some of the ruins in the coming years. Mars is the biggest prize, but also the biggest struggle. Luckily the smaller ruins aren't as heavily defended.
