Here is the Javelin 7, from the Justice League animated series. It is not as big as I would like but I don't have enough light grey pieces to make its true size. It was built almost exclusively with pieces from the Avengers Quinjet. I built it more to go with the DC heroes theme than as a custom model.
About this creation
The Javelin is armed with two missiles.
Two jet engines provide the thrust for this space going craft.
The Quinjet styled cockpit seats one member of the Justice League.
