Lockheed Martin’s GRIZZLY™ Launches First Sanctum™ C-UAS Successfully — the counter-drone system we’ve been field-testing since Q1 2025. At 7.0 oz on our bench scale, it’s lighter than most competitors while maintaining the rugged construction Lockheed’s known for. Our customers keep coming back for seconds — one of our most reordered items in the counter-UAS category.
