Guess we now know who will supply the non-Russian, non-Ukrainian Antares first stage.
ATK made the solid fuel SRB boosters for the Shuttle, and will do the same for NASA's Space Launch System.
ATK also proposed using a stretched SRB booster as the first stage of a manned launcher named Liberty, but it lost out in the second round of the NASA Commercial Crew program.http://www.spacenews...erger-of-equals
Orbital Sciences, ATK Announce "Merger of Equals"
PARIS — Satellite and rocket builder Orbital Sciences and rocket-motor builder ATK on April 29 said they have agreed to merge their aerospace and defense divisions in a $5 billion transaction that has been definitively approved by both companies.
The new company, to be called Orbital ATK, will count 13,000 employees and in 2013 would have generated $4.5 billion in revenue.
The companies said ATK would be spinning off its commercial sporting-equipment group to ATK shareholders.
The companies described the deal as a "merger-of-equals combination." ATK shareholders will have 53.8 percent the new company, with Orbital investors owning 46.2 percent.
