Really struggling to find a cartoon show I watched as a kid.
There were multiple pilots who flew jets / spaceships that would join together to make a giant robot. It was very Voltron-like, but the ships were not lions when flown individually. The pilots lived in a base which had a dome that would open and the base could go underground. I'm sure the ships were of a similar color scheme like Voltron and made up the all parts of the robot.
Any ideas or help would be awesome and appreciated
