WASHINGTON — The Defense Advanced Research Projects Agency awarded Voyager Technologies a $16.5 million contract to continue development of a solid rocket motor thrust-control technology designed to make missile propulsion systems more adaptable across different missions and weapons programs.
The award, announced May 26, funds Phase 2 of DARPA’s Burn n’ Go program, an effort launched last year to develop what the agency describes as a “propellant-embedded control technology” that would give solid rocket motors tailorable, post-manufacturing thrust control.
Traditional solid rocket motors are largely fixed once they are built. Their thrust output, burn duration and other performance characteristics are determined during manufacturing by the composition and geometry of the propellant inside the motor casing. While that approach supports large-scale production, it limits flexibility because different weapons or missions often require different motor designs.
DARPA’s program is aimed at changing that model by enabling aspects of a motor’s performance to be modified after production rather than requiring entirely separate propulsion systems for different applications.
The effort comes as the Pentagon pushes to expand missile production amid growing demand for air defense interceptors, long-range strike weapons and other munitions.
