Company context

We are the first and only company to demonstrate Link-16 connectivity from Space. This is a significant and critical milestone towards advancing the DoD’s national security missile defense strategy. York was also the first to achieve LEO-to-LEO laser link between PWSA vendors and Space-to-Ground laser links with another vendor. We believe these two capabilities are critical for Golden Dome contracts and demonstrate York’s strong position to win on that program.
