	Delta IV rocket - Wikipedia, the free encyclopedia
		The upper stage of the Delta IV is nearly identical to that of the Delta III.
		The Delta IV Medium+ (4,2) is similar to the Medium, but uses two Alliant-built 1.5-m (60-in) diameter solid rocket strap-on graphite epoxy motors (GEM-60s) to increase its payload capacity to 5,845 kg (12,890 lb) to GTO.
		The Delta IV Medium+ (5,2) is similar to the Medium+ (4,2), but has a 5-m–diameter payload fairing for larger payloads and a modified second stage with a 5-meter liquid hydrogen tank and stretched liquid oxygen tank.

	History of the Delta Launch Vehicle: Delta IV
		Delta II, and the oxidizer tank of Delta III, continue to use the same 8-foot-diameter dimension of the original Thor-Delta (though the tanks are now considerably longer).
		Delta IV is assembled in its Horizontal Integration Facility, then trucked to the pad to be raised to vertical by a hydraulic lift.
		For Delta IV, two sites have been brought out of mothballs: Canaveral's Pad 37, which hosted eight unmanned Saturn I and IB rockets before it was mothballed in 1972; and Vandenberg's SLC-6, a site first built for the Air Force’s Manned Orbiting Laboratory that was later intended to support polar-orbiting Space Shuttle launches.

	AWST STORY
		The first U.S. Air Force/Boeing "Delta IV Heavy" Evolved Expendable Launch Vehicle, a strong candidate to be the next U.S. manned launch vehicle, has been assembled here in preparation for rollout to Launch Pad 37B for several months of checkout before a demonstration flight in May 2004.
		The second Delta IV Heavy mission is scheduled for early 2005 and is set to carry a National Reconnaissance Office payload designated NROL-26.
		No other Delta IV EELV missions are scheduled between now and first launch of the Heavy, so while it will arrive horizontally, it will thunder away vertically without having to be returned to the HIF.
