L3Harris’ Greenville, Texas modification center designed, developed, and integrated the ASTOR system onto the aircraft. The facility then received approval from UK’s Defence Procurement Agency in January 2004 to self-certify the Sentinel’s modifications and airborne systems and complete flight testing.
The RAF Sentinel provided a long-range all weather theater surveillance and target acquisition system capable of detecting moving, fixed and static targets. The aircraft first saw service in Afghanistan as part of coalition forces following the 9/11 attacks. It flew 32,300 hours conducting approximately 4,870 sorties during its service life.
The Sentinel is one example of L3Harris’ high-quality, low-risk, cost-effective solutions for a diverse range of business jet platforms and missions. The company has more than 70 years of aircraft missionization experience with more than 15,000 modified aircraft delivered, and more than 50 business jet ISR aircraft on contract or delivered. This experience includes more than 800,000 hours of experience designing, building, integrating, testing and certifying Bombardier aircraft mission systems.
L3Harris’ onsite Multi-Sensor Test Facility enables rapid multi-discipline sensor certifications and calibrations, saving time and budget by reducing schedule, cost and flight hours for system validation.
