Creating Orbital ATK

The planned merger of the defense and space portions of ATK with Orbital Sciences will create a $4.5 billion company. Orbital and ATK's managements maintain that they are creating a much stronger company that will benefit from accelerated growth. In space, Orbital will bring its systems integration capabilities and ATK will provide its techologies. The result will be a much larger space company. Orbital's space work is about $1.5 billion annually, with ATK's space work totaling $1.2 billion.
