Orbital ATK

Recent recent expansion plans for this aerospace, ammunition, and integrated weapons system supplier will complement Arizona’s robust aerospace and defense sector that contributes $38bn annually to the Arizona economy and employs more than 52,000 workers.
Arizona Governor, Doug Ducey, and satellite manufacturer, Orbital ATK, last Friday jointly announced that the company is expanding its engineering operations in Gilbert, Arizona.

Governor Doug Ducey had this to say in a flurry of press release announcements:
“I am thrilled that one of the largest aerospace and defense companies in the world once again has selected Arizona for its expansion plans, and to support its critical operations,” said Governor Doug Ducey. “Arizona is a major player globally when it comes to aerospace, defense and avionics – and we continue to grow. This is a great partnership."
John Lewis, the mayor of Gilbert, was equally enthusiastic:
“A company like Orbital ATK could have expanded its operations elsewhere in the country. The fact that they plan to continue to invest in our great community is a testament to our mutually beneficial relationship and Gilbert’s focus on growing STEM occupations in aerospace and manufacturing sectors,” said Gilbert Mayor John Lewis. “These are some of the best jobs in Arizona and I’m proud they are happening in Gilbert.”

With additional facilities in Chandler and Mesa, Arizona, Orbital ATK has a total footprint in the state of close to almost 800,000 sq ft, contributing to over 1,750 high-tech aerospace and defense jobs.

Orbital ATK ISS cargo delivery set to launch
Orbital has also announced that it is in final preparations for the company’s next enhanced Cygnus spacecraft cargo mission to the International Space Station (ISS).
This will be Orbital ATK’s fifth operational mission (OA-6) to the ISS for NASA under the Commercial Resupply Services (CRS) contract, and the first Cygnus to conduct scientific experiments onboard the spacecraft.
For the second time, Orbital ATK will launch Cygnus atop a United Launch Alliance (ULA) Atlas V rocket, carrying approximately 7,900 pounds (3,600 kilograms) of cargo to astronauts aboard the ISS and small satellites that will be deployed directly from Cygnus.
Pending completion of final vehicle testing and acceptable local weather conditions, the launch is scheduled for Tuesday, March 22, at 11:05 p.m.
