That article says FY 2018, which means the payload could fly in 2017.

The interesting thing is, that this time an Atlas-V(411) instead of the Atlas-V(401) was ordered

SBIRS-GEO has either gained some additional mass or an different orbital injection profile will be used.

It's possible the extra SRB is for increased performance to allow the Centaur to fully de-orbit into the ocean.

Speaking of SBIRS, Aviation Week an excellent article on the program. Well worth the read:

Thanks. That article says that SBIRS GEO-4 will launch in 2016, while SBIRS GEO-3 has been put in storage and will launch in 2017. That doesn't really make much sense to me and doesn't fit with the earlier information, so I think the 2016 date may be a typo.

SBIRS GEO Flight 4 in Testing
 

Pictured here, the SBIRS GEO Flight 4 spacecraft in testing and storage at Lockheed Martin’s satellite manufacturing facility in Sunnyvale, California. Scheduled for launch in 2017, this will be the fourth satellite of the U.S. Air Force’s Space Based Infrared System.

Replying to an old comment here, but the Air Force announced that SBIRS GEO 3 and 4 would swap launch slots right around the time that article was published. The reason is that GEO-4 was ready in time for the GEO-3 launch slot, so this way they only need to transfer one satellite in and out of storage.

Updating thread title. SFN have indicated 27th of October and also list the configuration as a 411. Steven was right up thread

2017 looks like it will be a good year for solids on Atlas V

Can anyone clarify (confirm) whether GEO-3 and GEO-4 swapped launch slots or not?  The reason that I ask is that there is a patch available (ostensibly for GEO-3) that clearly reads GEO-IV in roman numerals. Was this patch released in error, or does it represent the actual payload? Forgive me for playing devils advocate...

The patch is for this mission and thread, GEO-4.  The patch is not for GEO-3. The ebay seller has the wrong name

[Spaceflight Now] Two U.S. military satellite launches delayed into next year

Separately and unrelated to AEHF, the SBIRS GEO Flight 4 launch is being delayed due to a “SBIRS program prioritization decision.”

It is tentatively rescheduled for launch on Jan. 18, 2018.

SBIRS GEO Flight-4 arrives in Florida, Prepares for January launch

CAPE CANAVERAL AIR FORCE STATION, Fla. -- The U.S. Air Force's Space Based Infrared System (SBIRS) program completed a major program milestone October 31, successfully delivering a Geosynchronous Earth Orbit (GEO) satellite Flight-4 to Cape Canaveral Air Force Station, Florida.

"The delivery, launch, and successful operation of GEO Flight-4 will mark the fulfillment of the original SBIRS baseline constellation and reaffirm our commitment to provide our country, warfighters, and senior leaders with timely, reliable, and accurate missile warning and infrared surveillance information." said Lt. Gen. John Thompson, SMC commander and Air Force program executive officer for space.

The delivery of GEO Flight-4 sets the path for final checkout of the space vehicle before launch. The satellite will be processed at the Payload Processing Facility located at Cape Canaveral Air Force Station, Florida.

A combined government and contractor team is already executing the final ground activities including a Launch Base Confidence Test to verify satellite integrity after shipment, an intersegment test to verify communication compatibility from the satellite to the on-orbit operations center and the final battery reconditioning for launch. Following these activities, the satellite will be fueled and prepared for integration with the Atlas V rocket.

"Finalizing the preparations for the fourth launch of a SBIRS GEO satellite is a big deal" added Col. Dennis Bythewood, director of the Remote Sensing Systems Directorate. "The entire team understands how significant this is, and we're ready to make it happen." The GEO Flight-4 satellite is scheduled
to launch from Cape Canaveral in January 2018.

The satellite was transported from the Lockheed Martin satellite integration facility in Sunnyvale, California, via a C-5 Galaxy aircraft. The C-5 crew from the 22nd Airlift Squadron, Travis AFB, California, ensured the satellite was transported safely and according to the time sensitive schedule. The security support provided by the 129th Rescue Wing, California Air National Guard, was essential to the success of the mission.

"The safety of the SBIRS satellite was entrusted to the very best, and we are appreciative of the transport and security services provided by the entire government and contractor team," Lt. Gen. Thompson said.

The SBIRS constellation is designed to replace the legacy Defense Support Program satellite constellation. SBIRS will continue to provide significantly enhanced capabilities to support missile warning, missile defenses, battlespace awareness and technical intelligence missions.
