Longer ASW engagement ranges could return shipboard torpedo tubes

Are quadruple torpedo launchers dead, or could they return?

They are not visible in most current designs, but greater anti-submarine engagement ranges could bring more ship-launched torpedo capability back.

The answer depends on future engagement range. If sensors and weapons let surface ships attack submarines at greater distance, designers may again value a substantial onboard torpedo battery. Without that change, helicopters and other systems retain the reach advantage.
