Those stealth fighters, while they were cool, weren't given names.
They're just stealth fighters, probably controlled remotely by the FATE Computer system. They probably wouldn't have used human pilots. Use of human pilots has probably since become obsolete by the year 2400AD, but I'm only assuming.
FATE and Chronopolis attacked Dinopolis, as Dinopolis's presence, as far as FATE was concerned, probably would've been an immediate threat to FATE and Chronopolis's existence in the future.
Remember, FATE's entire purpose and part of its programming is to preserve itself so that Project Kid can be carried out. That, and so the normal course of history remains unchanged.
