How Barents Sea destroyer tactics differed from Johnston at Samar

Were the destroyer actions at the Battle of the Barents Sea similar to USS Johnston's attack off Samar?

They shared a protective purpose, but Barents Sea used controlled feints while Johnston carried out genuine close attacks.

The Battle of the Barents Sea and Johnston's action off Samar resemble one another because destroyers confronted much stronger surface forces to protect vulnerable ships. Johnston's attack was direct and exceptionally brave, though its fit with established doctrine is debatable. British destroyers at Barents Sea used repeated dummy torpedo attacks, mixing in enough real launches to preserve the threat without exhausting their weapons. The tactical purpose was similar, but the degree of commitment and the management of torpedo inventory were different.
