Which conclusion about orbital laser constellations for BMD is supported in the material?

• A. They would provide only a very limited defense regardless of altitude
• B. They would provide a nearly leak-proof defense at high altitude
• C. They would be a perfect solution against all missile threats
• D. They would be cheaper and more capable than any terrestrial system

Answer: (A)

Evaluating how effective orbital laser constellations could be for ballistic missile defense shows that coverage and intercept capability are inherently limited. Even with lasers in space, delivering enough energy to a fast, rising missile within its brief boost window requires precise aiming, continuous line-of-sight, and sufficient dwell time to damage key components. Achieving that across all possible launch locations and trajectories demands a large number of satellites, constant coordination, and extremely reliable targeting, which are hard to maintain in practice. Weather, optical pointing errors, and system tolerances further constrain energy delivery, while countermeasures like decoys and maneuverable warheads complicate interception. These fundamental challenges mean the system would not be leak-proof or perfect, and it would still be far from cheaper or more capable than terrestrial solutions. The material therefore supports the view that such a constellation would offer only a very limited defense, regardless of altitude.
