How to combine 2 ships into the link? (X4: Foundations)

I have the beginning of the game, got involved in the fight(support), after the collision, the enemy froze with half HP, having troops, captured him and sent to the station(production), but I wanted to combine them into the wing and fly 2 ships(version 2,60), but how to do not understand. Can someone tell me.
All figured out.
