Why rugged weapons still depend on navigation resilience

Did Russian precision-weapon failures reflect abandoning rugged Soviet design, and could GLONASS be disrupted?

Not necessarily; the weapons may be mechanically rugged while guidance remains less precise and satellite navigation remains vulnerable to jamming.

Mechanical reliability and accuracy are separate qualities in Russian guided weapons during the invasion of Ukraine. A munition can be robust enough to launch and function while still falling short of American precision standards. Satellite navigation adds another dependency because GLONASS can be jammed or overwhelmed even when its military signal is better than public figures suggest. Ukrainian familiarity with parts of the system's development would make both sophisticated interference and brute-force disruption credible avenues to explore.
