Guided shells from heavy naval guns

The video considers shells that protect guidance hardware during launch and reveal it only after leaving the barrel. A 16-inch weapon might fire a smaller guided projectile in a sabot, or retain a full-calibre body with only the rear casing separating. Laser designation and deployable fins would turn fire control from predicting a ballistic impact point toward correcting the shell in flight. The payoff would be a smaller or more complex projectile that produces far more hits from each salvo, although the discussion remains a conceptual engineering exercise rather than a tested weapon specification.
