How can an amphibious force approach a defended shore when modern weapons reach far out to sea?
Short answerIt must either bypass strongpoints or suppress them, while exploiting the defender's difficulty finding targets at maximum weapon range.
NotesAn attacker can bypass a defended objective by landing elsewhere and advancing overland, or spend time, money, and firepower suppressing the coast directly. Neither option makes the operation easy because the force must still cross exposed water and then create access ashore. Maximum missile range is not the same as reliable engagement range because the defender first has to find and track a target at that distance. Reconnaissance and targeting pull the practical contest somewhere between the two sides' theoretical weapon limits.
