ATK (NYSE: ATK) propulsion, composite and spacecraft technologies supported Thursday's successful launch of a United Launch Alliance (ULA) Delta IV rocket from Space Launch Complex 37B at Cape Canaveral Air Force Station, Fla. This rocket carried the U.S. Air Force's fifth Block IIF navigation satellite for the Global Positioning System (GPS).
GPS IIF-5 is the fifth satellite delivered by prime contractor Boeing as part of the GPS IIF contract for 12 next-generation GPS space vehicles. GPS IIF satellites continue to modernize the GPS constellation while providing better positioning, navigation and timing services to civil and military users worldwide.
"ATK is pleased to provide an extensive selection of highly engineered products that support both the Delta IV rocket and the GPS IIF-5 satellite," said Blake Larson, president of ATK Aerospace Group. "Our affordable innovation and execution excellence continue to demonstrate ATK's leadership in the aerospace market."
The Delta IV medium-plus rocket that was used on this flight was in the 4, 2 configuration, which features two ATK 60-inch diameter Graphite Epoxy Motors (GEM-60). The 53-foot-long motors are mounted on opposing sides of the rocket, with one vectorable motor per side. The GEM-60s burn for approximately 90 seconds and provide more than 560,000 pounds of thrust to deliver the GPS IIF-5 satellite into orbit. The motors were produced at ATK's Magna, Utah, facility, and the composite cases, nose cones and aeroskirts were fabricated at ATK's Clearfield, Utah, facility. ATK has manufactured 53 GEM-60 boosters for the Delta IV launch vehicle since the initial flight in 2002.
Many other ATK components and structures also supported the Delta IV rocket:
For the GPS IIF-5 satellite, ATK provided a host of products and services:
The Block IIF series will replace the GPS Block IIA satellites that were launched between 1990 and 1997. The IIF space vehicles provide improved accuracy, enhanced internal atomic clocks, better anti-jam resistance, a civil signal for commercial aviation and a longer design life.
