Shipment of Seventh WGS Satellite Postures USAF for July Launch

Posted 6/17/2015 

6/17/2015 - LOS ANGELES AIR FORCE BASE, El Segundo, Calif.  -- The U.S. Air Force Space and Missile Systems Center's seventh Wideband Global satellite communication spacecraft arrived at the Shuttle Landing Facility at Kennedy Space Center, Fla., May 28.

The shipment of WGS-7 is an important milestone for the spacecraft and launch campaign. This spacecraft is undergoing final processing, encapsulation, and transport to the launch pad at Cape Canaveral Air Force Station, Fla. The launch is scheduled for launch July 22 aboard an EELV Delta IV rocket.

Wideband Global SATCOM provides anytime, anywhere communication for soldiers, sailors, airmen, Marines, and international partners through broadcast, multicast, and point to point connections.  WGS is the only military satellite communications system that can support simultaneous X- and Ka- band communications, with crossbanding that makes it transparent to the users to communicate across terminal types.

WGS currently collects and routes real-time data through X-band, Ka-band, and switchable X - Ka-band terminals, which are utilized for tactical and "comm-on-the-move communications." WGS supports a variety of missions, allowing combatant commanders to exert command and control of their tactical forces, from search and rescue efforts to military operations.

"The WGS constellation provides highly capable military communications that leverages cost-effective production methods and the latest technological advances," said Lt. Gen. Samuel Greaves, the Air Force's program executive officer for Space and SMC's commander.  "It takes a lot of hard work by the joint Air Force and contractor team to make this mission a success."

Built by Boeing, WGS-7 is the first satellite under a new contract approach contributing to a cost savings of more than $100 million. With three more satellites in production, the WGS constellation is expected to have a total of ten satellites on orbit by 2018.

Best quote heard during an inspection, "I was unaware that I was the only one who was aware."

Delta IV to Launch WGS-7 for the U.S. Air Force

Rocket/Payload: A Delta IV Medium+ (5,4) configuration will launch the seventh Wideband Global SATCOM (WGS-7) mission for the U.S. Air Force.

Date/Site/Launch Time: Wednesday, July 22, 2015, from Space Launch Complex-37 at Cape Canaveral Air Force Station, Fla. The 45-minute launch window opens at 8:07 p.m. EDT.

Webcast: The live broadcast will begin at 7:47 p.m. EDT.

Mission Description: WGS satellites are important elements of a new high-capacity satellite communications system providing enhanced communications capabilities to America's troops in the field for the next decade and beyond. WGS enables more robust and flexible execution of Command and Control, Communications Computers, Intelligence, Surveillance, and Reconnaissance (C4ISR), as well as battle management and combat support information functions. The WGS constellation augments the existing service available through the UHF Follow-on satellite by providing enhanced information broadcast capabilities.

Launch Notes: WGS-7 will be the 30th Delta IV mission since the vehicle's inaugural flight in 2002. This is the fifth flight in the Medium+ (5,4) configuration, and all launches in this configuration were WGS missions.

Launch Updates: To keep up to speed with updates to the launch countdown, dial the ULA launch hotline at 1-877-852-4321 or join the conversation at www.facebook.com/ulalaunch, twitter.com/ulalaunch and instagram.com/ulalaunch. #WGS7 #DeltaIV


Go Delta! Go WGS-7!

Launch Mission Execution Forecast

Vehicle: Delta IV WGS-7

Issued: 20 July 2015/1130Z (0730 EDT)

Valid: 23 July / 0007Z 0046Z

Launch Weather Team: (321) 853-8484

Synoptic Discussion: There is no significant change to the launch forecast today. A trough remains over the Southeast US suppressing the Bermuda High pressure ridge to the south. Westerly flow will continue over Central Florida for the next several days. An east coast sea breeze will develop today again causing afternoon thunderstorms, and the westerly flow will also bring thunderstorms that develop inland toward the Space Coast. This pattern will persist through the week including launch day. Also, an upper-level short-wave will move through Wednesday, enhancing afternoon thunderstorm activity, and strong wind gusts are possible as storms move through the area. Although these thunderstorms will likely impact the area during the countdown, they should move through before the launch window opens. Still, there is a chance some storms or anvil clouds could linger into the launch window. As for Space Weather, there are no complex sunspots posing a threat for solar flares, and solar activity is not a concern for launch. The primary concerns for launch are anvil clouds, cumulus clouds, and lightning. In the event of a 24-hour delay, no significant change is expected in the weather pattern, and the primary concerns remain the same, anvil clouds, lightning, and cumulus clouds.

Launch Mission Execution Forecast
Vehicle: Delta IV WGS-7

Synoptic Discussion: Again, there is no significant change to the launch forecast today. A trough over the Southeast US is suppressing the Bermuda High pressure ridge to the south. Southwest flow will continue over Central Florida for the next few days. An east coast sea breeze will develop today again causing afternoon thunderstorms, and the westerly flow will also bring thunderstorms that develop inland towards the Space Coast. This pattern will continue through Thursday. On launch day, thunderstorms will likely impact the area during the countdown causing lightning in the area and gusty winds, but storms should move through before the launch window opens. Still, there is a chance some storms or anvil clouds could linger into the launch window. As for Space Weather, there are no complex sunspots posing a threat for solar flares, and solar activity is not a concern for launch. The primary concerns for launch are anvil clouds, cumulus clouds, and lightning.

Looks like they're re-extending the panels that cover the DCUS/PLF on the MST so something is up.
