Underwater. Like SeaQuest, but less lame, and with more subs. Or underwater cowboys that use rocket ships.

What if we have a allusion to dairugger ?

What is dairugger?

Is the japanese counterpart of vehicle voltron.You say want see spaceships like mechas.

Wasn't Voltron Japanese already? Hmm...

Well if it features five smaller spaceships combining into a big spaceship/giant robot, then that is exactly what I am talking about.

Vehicle Voltron/Dairugger is 15 (Read: Fifteen) combining parts, and, if I recall, doesn't combine into one singular ship. It's not quite what you're looking for.

Thunderbirds. Funny if the heroes had a puppet companion while at it that work as gimmick items.

Yeah...not what I mean. Just five space ships making one robot.

I have a name for your space sentai uchuu sentai starranger.

They would do starger; get is their thing right now.
