United Launch Alliance’s Delta IV Heavy rocket carrying a payload for the National Reconnaissance Office successfully lifted off from Space Launch Complex 37 at CCAFS at 9:47 p.m. EST (0247 UTC) today. The launch was originally scheduled for 2005, but was delayed due to a number of issues, and lift-off took place at 0247 UTC on 18 January 2009.This was the first Delta IV Heavy mission for the NRO. Designated NROL-26, the mission is in support of national defense. This was the third Delta IV Heavy launch in Delta program history.
“This first Delta IV Heavy launch for the NRO is the culmination of years of hard work and dedication by the combined NRO, Air Force, supplier and ULA team,” said Jim Sponnick, ULA Vice President, Delta Product Line.
NROL-26 is a classified spacecraft which is to be operated by the United States National Reconnaissance Office.
According to reports by Aviation Week and other sources, NROL-26 is believed to be either the first Intruder satellite or an Advanced Orion, ELINT satellite.
Aviation Week reports, "It fundamentally involves America's biggest, most secret and expensive military spacecraft on board the world's largest rocket." The combined cost of the spacecraft and launch vehicle has been estimated to be over US$2 billion.

ULA is pleased to contribute to our nation’s security, and to continue our strong partnership with the NRO. We look forward to launching many more NRO missions on ULA’s Delta IV Medium, Delta IV Heavy and Atlas V vehicles.” The ULA Delta IV Heavy vehicle featured a center common booster core with two strap-on common booster cores. Each common booster core was powered by the RS-68 cryogenic engine. An RL10B-2 cryogenic engine powered the second stage. Both engines are built by Pratt & Whitney Rocketdyne. The payload was encased by a 5-meter diameter (16.7-foot diameter) aluminum, tri-sector payload fairing. ULA constructed the Delta IV Heavy launch vehicle in Decatur, Ala. This was the first launch for ULA in 2009. ULA's next launch is NASA’s NOAA-N Prime mission currently scheduled for Feb. 4, aboard a Delta II from Space Launch Complex-2 at Vandenberg Air Force Base, Calif.
