L3Harris Delivers Operational Realism for Missile Defense
To ensure these critical systems — and those systems yet to be developed — work every time, we must have a robust testing infrastructure, writes Scott Alexander, President of Missile Solutions, Aerojet Rocketdyne, L3Harris, in Defense News.
Our Hypersonic and Ballistic Tracking Space Sensor satellite, known as HBTSS, launched in February 2024 and is a proven on-orbit system capable of tracking maneuvering hypersonic missiles. This is expected to be a core component of the Golden Dome architecture. If we were to get an award in the next few months, we could launch enough satellites into orbit while President Trump is still in office, thereby having complete coverage of the U.S.
Multi-Domain, Layered Solutions
To create next-generation missile warning and defense capabilities for America, the Department of War needs mission-oriented industry partners with expertise in delivering integrated solutions. L3Harris produces a range of proven technologies that enable a layered, multi-domain architecture, including satellites, datalinks, multi-domain ISR, precision fire-control sensing, propulsion and control systems for interceptors, as well as ballistic missile targets for testing.
