According to ULA the next GPS IIF satellite will leave on 14 July 2011. But, I have seen reference to a possible delay to assess a spacecraft component issue.

Nice to see an article about this process. The general public is usually not informed about the long work of a launch campaign.

Looks like a busy July for launches. Anyhow I was amazed to lookup the new GPS IIF-2 vs the old models. The early models were launched on Delta II's. Some great HW being launched.

Is the launch window still 0649-0708 GMT?
That would be 2:49-3:08 a.m. EDT; deep darkness at the launch site! -

According to ULA, that is the current launch window. The launcher is to be Delta 355. GPS IIF-2 is Space Vehicle Number 63 (SVN63).
It's going somewhere into GPS Plane D. I'm thinking it will eventually replace SVN24 that was launched way back in 1991 on the 4th of July.
If this mission proceeds as did inaugural Delta IV GPS launch, the ground trace shows the satellite arriving on orbit somewhere over the South China Sea. Spacecraft separation occurs 3 hours and 33 minutes into the mission.
GPS IIF satellites go directly to the GPS constellation. Earlier Block II GPS satellites were all launched by Delta II and released into a transfer orbit awaiting a boost from an apogee kick motor.
The Air Force expects the satellite will be ready for us all to use after a thirty day on orbit positioning and engineering checkout.

Timing suggests ordnance or spacecraft problem.

I was planning on heading out to Port Canaveral for this launch. Has it truly been delayed until Friday morning? I can't find any confirmation of this. Even ULA's site is still saying 7/14.

Here's what ULA just put out:
FOR IMMEDIATE RELEASE
GPS Block IIF satellite launch postponed 24 hours
CAPE CANAVERAL AIR FORCE STATION, Fla. – The launch of a Delta IV rocket carrying the GPS IIF-2 payload for the Air Force is being postponed 24 hours to allow the GPS spacecraft team time to complete an assessment of a technical item.
The launch is rescheduled for Friday, July 15 from Space Launch Complex-37 at Cape Canaveral Air Force Station, Fla., at the opening of a 19-minute window at 2:45 a.m. EDT. The forecast for July 15 shows a 70 percent chance of favorable weather conditions for the launch.
Accredited media representatives interested in covering the launch from the Kennedy Space Center News Center must report by July 15, at 12:30 a.m.. to the parking lot at the KSC Media Services Press Accreditation Building on State Road 3 across from Air Liquide, for Air Force badging and escort. Media representatives must provide proper credentials and two forms of identification, at least one with a photo. Drivers must have a valid current driver's license, motor vehicle registration and proof of insurance, and follow all safety and security procedures and instructions.

Notes:
1. Remote camera set-up: Media representatives interested in setting up remote cameras must report to the parking lot of Space Florida/SpaceX, near the CCAFS front gate, on July 14, at 3:15 p.m. for badging and escort to the SLC-37 area. Air Force and ULA Communications representatives plan to meet and escort media to the Kennedy Space Center Press Site. Escort and access is contingent upon operational constraints.

This launch excites me as not focused on a Delta IV before.
This is an USAF launch? Is the payload processed at Aerotech or other. Any pics available?
