Full statement from Orbital ATK about OA-7's move to Atlas V (self.OrbitalATK)

Following a successful Antares launch for the recent OA-5 Commercial Resupply Services mission and subsequent rendezvous and berthing of the Cygnus spacecraft with the International Space Station, Orbital ATK has responded to NASA's needs for enhanced schedule assurance for cargo deliveries and maximum capacity of critical supplies to the space station in 2017 by once again partnering with United Launch Alliance to launch Cygnus aboard an Atlas V for the upcoming OA-7 mission in the spring timeframe. The company will be ready to support three cargo resupply missions to the station next year, and will work with NASA to finalize the flight schedule.
The schedule provides margin flexibility for the entire Antares workforce, who worked tirelessly for the past several months to prepare and successfully launch the upgraded rocket from Wallops Island on the OA-5 mission. This plan also allows NASA to again capitalize on the operational flexibility built into Orbital ATK's Cygnus spacecraft to assure the space station receives a steady and uninterrupted flow of vital supplies, equipment and scientific experiments. With four Antares launches from October 2016 to early 2018, together with the Atlas V rocket, this plan represents the company's commitment to establishing schedules that are realistic and achievable.
Orbital ATK's remaining missions to be conducted in 2017 and 2018 under the CRS-1 contract will launch aboard the company's Antares rockets from NASA Wallops Flight Facility in Virginia.

Orbital to launch next Cygnus mission on Atlas 5

WASHINGTON — Citing a desire to both maximize the cargo delivered to the International Space Station and ensure it stays on schedule, Orbital ATK said Nov. 4 it will launch its next Cygnus mission on an Atlas 5 rather than its own Antares rocket.
Orbital ATK said that the OA-7 Cygnus mission, previously planned to launch on an Antares rocket from Wallops Island, Virginia, will instead launch on a United Launch Alliance Atlas 5 from Cape Canaveral, Florida, in the spring of 2017. The company said this is a one-time arrangement, with future Cygnus launches returning to the Antares.
The shift in launch vehicles for OA-7 was a "collaborative effort" between NASA and Orbital ATK, said Frank DeMauro, vice president of human space systems in the company's Space Systems Group. "We jointly realized that getting a little more cargo on OA-7 in the spring was in NASA's interest," he said in a Nov. 4 interview. "We jointly realized that having the highest assurance that we could meet the schedule was also in NASA's interest."
Launching on an Atlas, DeMauro said, allows the Cygnus to carry more than 300 kilograms of additional cargo versus using an Antares. The OA-7 mission will be able to accommodate more than 3,500 kilograms of cargo in its pressurized module, as well as an external cubesat deployer from NanoRacks, bringing its total capacity to about 3,600 kilograms.
DeMauro said there were no issues with the upgraded version of the Antares that launched for the first time Oct. 17 on the OA-5 Cygnus mission. However, moving the launch to the Atlas does give the company's workforce "margin flexibility" to prepare for the next launch, which now is likely to take place in the middle of 2017. "It is fair to say that the Atlas will have a higher probability of supporting that mission in the spring, even though we do believe Antares would have done that," he said.

That additional performance and schedule assurance comes as two other cargo spacecraft that support the ISS suffer delays. Launches of SpaceX Dragon spacecraft are on hold as the company continues an investigation into a Sept. 1 explosion of a Falcon 9 during preparations for a static-fire test. The next Dragon mission, previously scheduled for November, is now expected to take place no earlier than January, depending on when the Falcon 9 returns to service.
A Japanese H-2 Transfer Vehicle mission also experienced delays because of a spacecraft leak found during launch preparations. That mission, originally planned to launch in early October, is now scheduled for Dec. 9.
DeMauro said Orbital ATK's Commercial Resupply Services (CRS) contract with NASA gives the company flexibility to switch launch vehicles for Cygnus missions. He declined, though, to discuss any increased costs to Orbital ATK by switching launch vehicles or if NASA will pay more for this mission as a result, citing proprietary company financial information.
"We are still working to finalize the details of this change," he said. "While we expect it to go forward, we're still working through the final details."
From an operational standpoint, DeMauro said there will be little difference between OA-7 and two previous Cygnus missions that launched on Atlas 5 vehicles in December 2015 and March 2016. Orbital ATK ordered those launches to continue cargo services after the failure of an Antares rocket carrying another Cygnus spacecraft in October 2014.
DeMauro said the company will use the same payload processing facility at NASA's Kennedy Space Center for the OA-7 mission as it did for the two previous ones, and follow similar procedures to prepare the spacecraft for launch. "That's one of the things that enabled such a quick turnaround," he said.
After OA-7, DeMauro said Orbital ATK will resume using Antares vehicles for Cygnus mission for the remainder of its current CRS contract, likely to run through 2018. That includes two Antares launches in the second half of 2017 and two in 2018. The exact schedule of missions will depend on the overall ISS schedule and when NASA needs those missions to fly, he said.

Ради 300 кг переплачивать 50 млн? Собственно НАСА все равно. Это Орбитал попал.

Откуда взялась цифра в 300кг?

Судя по этому:

CRS-5 — Atlas 5 — 7,758 pounds — Launched March 22, 2016 
CRS-6 — Antares — 5,163 pounds — Launched Oct. 17, 2016

разница в полтора раза, а конкретно на 2600 фунтов = 1180кг

Orbital CEO: No decision on buying Atlas 5 for NASA ISS cargo; but seems prudent to add to 3 Antares missions in 12 months from early 2017.

NASA, Orbital ATK Target Spring 2017 for Next Cargo Mission  
 
Orbital ATK has contracted with United Launch Alliance (ULA) for an Atlas V rocket for the company's next cargo resupply mission for NASA to the International Space Station. This will be Cygnus' third flight atop an Atlas V rocket from Cape Canaveral Air Force Station in Florida. Launch is targeted for spring 2017.
This mission is one of Orbital ATK's previously awarded 11 missions under its first commercial resupply services (CRS-1) contract with NASA. Both the agency and Orbital ATK mutually agreed to use of the Atlas V in order to expedite the company's seventh contracted resupply mission, and their CRS-1 contract was modified Nov. 8, 2016.
"We're continuously working with all our partners on range availability, space station traffic and other factors to maximize utilization, operation of the station in a safe and effective way as we use it as our test bed for preparing for longer duration missions farther into the solar system, including the Journey to Mars," said Kirk Shireman, manager, ISS Program at NASA's Johnson Space Center in Houston.
NASA, the Mid-Atlantic Regional Spaceport and Orbital ATK continue to work toward the next Antares launch from the agency's Wallops Flight Facilities in Virginia. Missions from that facility will resume with Orbital ATK's eighth and subsequent resupply missions to the station next year.
Orbital ATK launched a successful flight Oct. 17 from Wallops on its upgraded Antares. By contracting with ULA for its next flight, the company will be able to meet NASA's near and long term cargo needs.
"The schedule provides margin flexibility for our Antares workforce, who worked tirelessly for the past several months to prepare and successfully launch the upgraded rocket from Wallops Island on our sixth contracted commercial resupply services mission," said Frank DeMauro, vice president, Orbital ATK. "This plan also allows NASA to again capitalize on the operational flexibility built into Orbital ATK's Cygnus spacecraft to assure the space station receives a steady and uninterrupted flow of vital supplies, equipment and scientific experiments."
NASA and its partners' long-term planning for operating the station ensures that astronauts aboard the station are safe and have sufficient supplies. In addition to the recent Cygnus delivery to station, a Russian Progress and Japanese HTV will carry additional cargo to the orbiting laboratory before the end of the year.
NASA's and the National Lab's research and technology development activities continue aboard the space station. Keep up with the International Space Station, and its research and crews, at: http://www.nasa.gov/station
