In fact, its Government Baseline fairing is a modified Boeing-built Titan IV fairing, with an overall length of 65 feet. The Lacrosses and KeyHoles require a fairing of about this length. > Now to wait and see how bright the atlas 5 will be in orbit. The Atlas 5 will leave a 3.05 m X 12.68 m Centaur stage in orbit. This length includes the nozzle. The Delta IV has 2 second stage variants that will reach orbit. The first is approximately 4 m x 12 m, including nozzle, and can be used with either the Delta IV-M or H (M denotes medium-lift); the second is approximately 5 m x 14 m, including nozzle, used exclusively by the Delta IV-H. So we can look forward to additional large, bright rocket bodies to observe.
