I want the name of a animation from the 90’s

The story line is : a competition of two jet (who can transform in to giant robot) for a army contract. The two pilot are old friend/enemie. And everything become more complicated when a third jet enter in the competition and the third pilote is a IA. At the end they're fighting agains the IA. Because the IA want to dominate the world's.

What do you mean by "IA"?

Can you tell us any more about the anime, like what style it was? Was it similar to like Gundam or Voltron, or was it a North American knockoff like Transformers? Any more details you can provide, like character names, or other specific details, would make it easier for us to identify.
