You never knew where you get launch dates and times from. ;)
According to the KSC Visitor's Center's future events list (https://www.kennedyspacecenter.com/events.aspx), liftoff is scheduled at 2:39 pm Eastern (18:39 UTC). Someone who have more time than me may try to calculate which orbital plane of the GPS system is this one heading for. ::)

From a recent presentation of State Department, "SV-9 is in production testing".

-
Yes. That makes sense that SV-9 (SVN 70) is in production testing, because it is getting skipped in the launch order.
NGA has updated their website, and it now lists SVN-71 as the IIF-9 mission:

Not to be snippy, but is that a cost savings measure to save on draping the launch logo over the tower? It just looks underwhelming.

Please indulge what is surely a dumb question. Wikipedia lists Delta IV medium payload capacity at 4,200kg to GTO and Delta IV medium+ (4,2) payload capacity at 6,150kg to GTO. Wikipedia also lists the mass of GPS block IIF at 1,630kg going to MEO. Is MEO a higher energy orbit than GTO, does Wikipedia have the numbers wrong, could ULA use a Delta IV medium without the +? I guess the MEO orbit is higher energy. Thanks in advance.

The GPS mission is a 3 burn for the upper stage and places the spacecraft in the final orbit. GTO is not the final orbit for spacecraft and the spacecraft has to perform apogee burns.

The mission is directly to a 20,368 x 20,368 km x 55 deg GPS orbit, which does require more delta-v than a geosynchronous transfer orbit. Delta 4M+4,2 can lift 2.986 tonnes to this orbit, according to the 2007 User's Guide. Delta 4M was listed at 1.988 tonnes.
This does raise a question about why a straight Medium wasn't used. It likely has to do with desired margin and with the fact that the User's Guide numbers include the mass of the payload attach fitting, which might weigh a couple hundred kg. It is also possible that (1) Delta 4 can't really do what the 2007 Guide said it could do or (2) that the satellite weighs more than we think.

Perhaps something to do with the target orbital plane ? Some orbital planes align almost perfectly with a launch from the cape, others don't. I'll be corrected in 10,9,8,7,6,5,4,3,2,1,launch :)

Launch Mission Execution Forecast
Vehicle: Delta IV GPS IIF-9
Issued: 22 March 2015 / 1230Z (0830 EDT)
Valid: 25 March 2015 / 1832 – 1850Z (1432 – 1450 EDT)
Synoptic Discussion: A weak front will move into the area Monday bringing showers and just a slight chance of a thunderstorm. No severe weather is expected. The front will move off to the east Tuesday, and high pressure will build in to the north improving weather. On launch day, the high pressure area to the north will move east causing winds to shift to the southeast and increase through the day. The onshore wind along with low-level moisture will cause isolated morning coastal showers, but showers will decrease by the afternoon launch window. The primary concerns for launch are flight through precipitation and cumulus clouds. Thursday, gusty winds are expected in the morning, but as the high to the east moves away the wind speed will shift southwest and decrease. The moisture in the atmosphere deepens as well, and there is a chance of cumulus clouds with precipitation to develop along the afternoon sea breeze. The primary concerns for a 24-hour delay are, again, flight through precipitation and cumulus clouds.

The rotation of the Earth ensures that CCAFS passes through each plane of the constellation twice a day. So all planes are equally easy to reach. All that changes is the launch window.
-
Not if you are aiming for a specific slot in the plane.
-
Not if you are aiming for a specific slot in the plane.
Nope, getting to the specific slot is easy once on the right plane.
GPS injections are executed on a higher orbit, like 100Km too high, too high = slower, so the injection is already to an orbit where all they need to do is leave the bird alone while it moves westward compared to other birds, bring it down to the proper (lower orbit) when close to the target. That's part of the performance reserve demanded of each launch (that is actually used).
-
Not if you are aiming for a specific slot in the plane.
Do they actually do that? If the satellite is injected into the correct plane can it not just drift to its operational spot during commissioning like a comsat in GSO?

Vehicle: Delta IV GPS IIF-9
Issued: 25 March 2015 / 1200Z (0800 EDT)
Valid: 25 March 2015 / 1836 – 1854Z (1436 – 1454 EDT)
Synoptic Discussion: A strong low-level inversion is prevalent over Cape Canaveral causing morning fog. Visibility is down to less than ½ statute miles, but this fog will burn off between 1100L and 1200L. The high pressure area moving off the U.S. East Coast will cause winds to gradually veer and be from the east-northeast, but gusty winds are now forecast to hold off until Thursday. Showers are occurring along a convergent band 70 nautical miles to the southeast, but these will not be a concern for launch. High clouds are streaming over the area, but are located above the -20C level and are not a concern for launch. With dry air in the mid-levels of the atmosphere, there is only a slight concern for cumulus clouds for launch and the forecast is decreased to just a 10% chance of violating weather constraints. The primary concern for launch is cumulus cloud development. Thursday, the high pressure area to the northeast moves off to the east as a low pressure system moves into the Eastern U.S. Wind flow will shift and be from the southeast, and additional moisture will migrate in from the south as well. Given these factors, there is an increased chance of afternoon showers and late afternoon thunderstorms. Mid-level clouds will also be more prevalent, causing concern for thick cloud layers above the freezing level. Due to this additional concern, the probability of weather constraint violation for a 24-hour delay increased to 60%. The primary concerns for a 24-hour delay are flight through precipitation, cumulus clouds, and thick cloud layers.

This is ULA’s fourth launch in 2015 and the 95th successful launch since the company was formed in December 2006.
United Launch Alliance Successfully Launches Second
Mission in Less than Two Weeks
Cape Canaveral Air Force Station, Fla., (March 25, 2015) – A United Launch Alliance (ULA) Delta IV rocket successfully launched the ninth Global Positioning System (GPS) IIF satellite for the U.S. Air Force at 2:36 p.m. EDT today from Space Launch Complex-37. This is ULA’s fourth launch in 2015 and the 95th successful launch since the company was formed in December 2006.
“Congratulations to the Air Force and all of our mission partners on today’s successful launch of GPS IIF-9! The ULA team is privileged to work with this world-class U.S. government and contractor mission team, and we are proud to contribute to the GPS capabilities that were delivered to orbit today,” said Jim Sponnick, ULA vice president, Atlas and Delta Programs. “This entire team is focused on 100 percent mission success, one launch at a time, and also providing on-time launches to meet our customer’s mission needs.”
This mission was launched aboard a Delta IV Medium-plus (4,2) configuration Evolved Expendable Launch Vehicle (EELV) using a single ULA common booster core powered by an Aerojet Rocketdyne RS-68 main engine, along with two Orbital ATK GEM-60 solid rocket motors. The upper stage was powered by an Aerojet Rocketdyne RL10B-2 engine with the satellite encapsulated in a four-meter-diameter composite payload fairing.
GPS IIF-9 is the ninth in a series of next generation GPS satellites and will join the GPS worldwide timing and navigation system utilizing 24 satellites in six different planes, with a minimum of four satellites per plane positioned in orbit approximately 11,000 miles above the Earth’s surface. The GPS IIF series provides improved accuracy and enhanced performance for GPS users.
ULA's next launch is the Atlas V AFSPC-5 mission for the United States Air Force, scheduled for May 6 from Space Launch Complex-41 from Cape Canaveral Air Force Station, Florida.
The EELV program was established by the United States Air Force to provide assured access to space for Department of Defense and other government payloads. The commercially developed EELV program supports the full range of government mission requirements, while delivering on schedule and providing significant cost savings over the heritage launch systems.
With more than a century of combined heritage, United Launch Alliance is the nation’s most experienced and reliable launch service provider. ULA has successfully delivered more than 90 satellites to orbit that provide critical capabilities for troops in the field, aid meteorologists in tracking severe weather, enable personal device-based GPS navigation and unlock the mysteries of our solar system.

Orbital ATK Contributions Vital to Successful Launch of ULA's Delta IV Rocket
ULA Delta IV Launch Vehicle Lofts GPS IIF-9 Satellite Into Orbit for U.S. Air Force
GPS IIF-9 First of Three GPS Satellites to be Launched in 2015
(Dulles, Virginia 26 March 2015) – Orbital ATK, Inc. (NYSE: OA) technologies played a crucial role in Wednesday’s successful launch of a United Launch Alliance (ULA) Delta IV rocket from Cape Canaveral, Florida, and the on-orbit operation of a new Boeing GPS IIF satellite. The satellite will provide improved accuracy, signal strength and quality to America’s warfighters, allies and civil users worldwide.
Orbital ATK’s contributions to the Delta IV and GPS IIF include cutting-edge technologies from across the company. In addition to the state-of-the art solar arrays and other critical components on the GPS IIF satellite, contributions include the two Graphite Epoxy Motors-60 (GEM-60), large composite structures and the main engine nozzle.
“Orbital ATK’s contributions to the Delta IV GPS IIF-9 mission are prime examples of the affordable, innovative and reliable products we offer,” said Ron Grabe, President of Orbital ATK’s Flight Systems Group. “These products are crucial to our nation and millions of GPS users around the world.”
ULA’s Delta family of launch vehicles has been lifting high-priority government and commercial payloads to orbit for more than 50 years. This launch marks the 371st Delta rocket since 1960 and the 29th Delta IV since 2002. It also marks the 69th GPS satellite launch and the 55th to use a Delta rocket.
The Delta IV medium-plus rocket flew in a configuration featuring two Orbital ATK commercial GEM-60 solid rocket motors produced in Magna, Utah. These motors boast a flawless record and are the 43rd and 44th GEM-60s to fly. Their 90 seconds of flight time and 560,000 pounds of thrust boosted the 371st Delta vehicle into the sky.
The nozzle for the launch vehicle’s RS-68 engine was designed and manufactured at Orbital ATK’s facility in Promontory, Utah. The nozzle design includes an Orbital ATK-developed thermal protection material that is capable of shielding the nozzle from the extreme heat of launch when external temperatures can exceed 4,000 degrees Fahrenheit.
The Delta IV composite structures manufactured by Orbital ATK provide higher performance with lower weight and include:
• The GEM cases, manufactured using advanced wet winding techniques at Orbital ATK’s Clearfield, Utah facility.
• The fairing, payload attach fitting and diaphragm, interstage, centerbody and thermal shield, all produced using advanced hand layup, machining and inspection techniques at Orbital ATK’s Iuka, Mississippi facility.
For the GPS IIF-9 satellite, Orbital ATK provided a host of products and services:
• Orbital ATK’s Goleta, California facility designed and manufactured the satellite solar arrays and a deployment boom. Orbital ATK has achieved 100 percent on-orbit success on all solar arrays and deployable systems delivered and launched to date.
• Orbital ATK’s San Diego, California facility manufactured the composite solar array substrates.
• Orbital ATK’s Commerce, California, facility had responsibility for the ullage tank assembly, including the blankets, heaters, thermistors and pressurant lines. This tank is a spherical vessel constructed of titanium.
• Orbital ATK’s Beltsville, Maryland facility provided heat pipes for the GPS IIF equipment and radiator panels.
• Orbital ATK’s Rancho Bernardo, California facility performed final assembly and RF (Radio Frequency) testing of the antenna suite for GPS IIF between 2003 and 2010.
ULA will deliver two more GPS IIF satellites into orbit this year, and then another in early 2016 to complete the IIF series. These satellites will be delivered into medium-Earth orbits and will circle the globe every 12 hours, providing critical Navstar positioning, velocity, and timing assets fully functional until the next-generation GPS Block IIIA comes online in 2016. In addition to their civilian usage, the Block IIF satellites boast enhanced accuracy, reprogrammable processors, interference-free signals for commercial aviation, search and rescue capability, and a new Military code that is better resistant to electronic jamming.

According to http://spaceflightnow.com/2015/03/27/delta-4-rocket-evolving-the-upgraded-main-engine/ (http://spaceflightnow.com/2015/03/27/delta-4-rocket-evolving-the-upgraded-main-engine/), this flight marks the last use of the original RS-68 and the different DIV-M cores.
Jim might be able to confirm this...

Multiple teams produce multiple patches. I've even seen patches for transportation of spacecraft to the launch site. One of those, for some NASA science payload read "Carefull please, only child" with the patch showing a nurse holding a pillow with the spacecraft positioned on top of the pillow.
