Orbital ATK's Flight Systems Group provides products and services that span the launch, strategic missile and missile defense, and aerospace structures markets. The group is a premier producer of solid rocket propulsion systems and specialty energetic products; a leading provider of small- and medium-class space launch vehicles for civil, defense and commercial missions; a major supplier of interceptor boosters and target vehicles for missile defense; and a world class manufacturer of composite primary and secondary structures for commercial and military aircraft and launch vehicles.
Space Launch Vehicles
Orbital ATK’s family of space launch vehicles has carried out more than 70 launches, boosting more than 160 satellites into orbit.
Our space launch vehicles are the industry standard for boosting small payloads to orbit. Our innovative Pegasus® rocket is launched from the company's "Stargazer" L-1011 carrier aircraft and has proven to be the industry's small space launch workhorse, having conducted 43 missions from six different launch sites worldwide since 1990.
Our Minotaur ground-launched rockets combine Pegasus upper stages with either government-supplied or commercially available first-stage rocket motors to boost larger payloads to orbit. Our Minotaur IV, V & VI rockets combine decommissioned Peacekeeper rocket motors with proven Orbital avionics and fairings to provide increased lifting capacity for government-sponsored payloads.
Orbital ATK entered the market for medium-class launch services in 2013 with the introduction of the Antares™ rocket. Antares has now successfully launched six cargo delivery missions to the International Space Station for NASA.
Orbital ATK provides a wide range of reliable solid motors for the company's own vehicles and for most other launch providers in government and commercial markets. For defense programs, the company produces propulsion systems for the Trident II D-5 and Minuteman III strategic missiles and the company's Ground-based Midcourse Defense interceptor and various missile defense target vehicles.
Orbital ATK is also building the five-segment boosters for NASA's heavy lift Space Launch System (SLS) and the main launch-abort motor for the Orion crew capsule. Orbital ATK propulsion systems are employed in the company's Pegasus, Minotaur and Antares rockets as well as in other vehicles such as the Graphite Epoxy Motor (GEM) boosters for the Delta II and Delta IV launch vehicles.
Missile Defense Systems
Orbital ATK is an industry-leading provider of sophisticated suborbital launch vehicles for the nation’s missile defense systems. In the last 10 years, we have conducted more than 75 major launches for U.S. and allied countries’ missile defense programs.
Orbital ATK is the sole provider of interceptor boosters for the U.S. Missile Defense Agency’s Ground-based Midcourse Defense system designed to intercept and destroy long-range enemy missiles. The group is also a primary supplier of highly reliable target vehicles that serve as "threat simulators" to provide high-fidelity facsimiles of enemy missiles in the testing and verification of missile defense systems.
Orbital ATK is a leading supplier in critical composite structures for the aerospace and defense industries. Employing advanced composite manufacturing technologies, the company produces highly-engineered, lightweight and reliable structures for commercial and military aircraft programs such as the Airbus A350, Boeing 787 and Lockheed Martin F-35 as well as for the ULA Delta and Atlas launch vehicles. These structures cover a wide range of physical sizes and service temperature requirements for some of the industry’s most demanding applications.
