Why anti-ship ballistic missiles create escalation risk

Could an anti-ship ballistic missile launch be mistaken for a nuclear or strategic attack?

Yes; similar launch signatures and limited warning time can create severe escalation risk even when the intended target is only a ship.

Tactical and strategic missiles are not normally identical, but anti-ship ballistic weapons can share launch profiles and technology with nuclear-capable systems. Early-warning networks may detect the launch before leaders know the payload or target. A nervous or trigger-happy opponent could interpret a conventional naval strike as the opening of a strategic attack and respond before clarification arrives. Anti-ship ballistic missiles are therefore described as headline-grabbing weapons whose political and escalation costs may outweigh more conventional ways to attack a ship.
