Unique superweapon/technology ideas?

Ace combat superweapons have always been some variation of: - Stationary structure/bases - Giant aircraft - Giant submarine - Satellite

Do you think there could be potential for more unique superweapon ideas or technologies that could still be semi grounded for strangereal?

Taking inspiration from Armore Core: For Answer, maybe walking mobile fortresses?

Landships from project wingman?

A scramjet equipped armoured train with artillery?

Ground effect vehicles/Ekranoplans?

A fully equipped orbital station that drops troops and tanks anywhere with self defense capabilities?

Maybe an underground weapons platform similar to the ice worm from Armored core 6? But probably less mobile and less physical slamming and more "It drills very deep and pops out the other end guns and missiles blazing" type of thing. And leaves a fully functional fortress behind when drilling back into the ground or a very large hole (perfect for tunnel runs).

Massive floating barge weapons platforms? (Which wouldn't be too different to ships I guess so probably not)

Maybe an automated factory that makes bio-mechanical cyborg whales with weapons? Or robot squids? Actually it would be nice to see some organic/nature influenced weapons and designs.
