Northrop Grumman’s Pegasus Rocket Powers Mission to Extend NASA’s Swift Observatory
CHANDLER, Ariz. – July 3, 2026 – Northrop Grumman Corporation (NYSE: NOC) successfully launched Katalyst Space’s LINK spacecraft aboard a Pegasus rocket from the Kwajalein Atoll, contributing to NASA’s mission aimed at extending the operational life of the Neil Gehrels Swift Observatory.
- This event marks Pegasus’s 46th launch, showcasing its patented air-launched system, which offers unparalleled flexibility, precision, and cost-effectiveness tailored to the mission’s unique orbit and timeline.
- Pegasus is built on a legacy of engineering excellence, designed for rapid assembly, testing, and launch, making it an ideal choice for missions with tight time constraints.
- The rocket was elevated to approximately 41,000 feet by Northrop Grumman’s Stargazer L-1011 aircraft before being released and igniting its first stage.

Expert Insight:
Wes Collier, vice president of launch systems at Northrop Grumman, stated, “With a readiness for launch in under eight months, Pegasus is the preferred choice for missions requiring immediate deployment. Its air-launch design and proven Orion motors enable payloads to access orbits that are difficult for other rockets to achieve.”
Program Overview:
Pegasus, a three-stage small-class launch vehicle, has successfully deployed nearly 100 satellites into low-Earth orbit since its inception in 1990, making history as the world’s first privately developed space launch vehicle. Its responsive air-launch capability allows it to operate globally with minimal ground support, providing access to orbits that would be challenging for conventional launchers. Northrop Grumman’s Orion motors ensure reliable propulsion across all three stages of Pegasus.
The Swift Observatory, constructed at Northrop Grumman’s facility in Gilbert, Arizona, was initially designed for a two-year mission when it launched in 2004. However, it has continued to gather invaluable data that exceed its original objectives for over two decades, with ongoing operational support still provided by the company.
