A Submarine Near Iran Fired a Torpedo at a U.S. Aircraft Carrier.lh

Yet from the outside, nothing dramatic happened.

The carrier did not execute a violent evasive turn. There was no visible surge of speed, no abrupt maneuver that would signal panic. Instead, the ship held steady on its course, cutting forward through calm water.

To an untrained observer, that might look like hesitation. In reality, it was the opening move of a carefully calculated response.

Modern torpedoes are not simple, straight-line weapons. Many employ acoustic homing systems, sending out pulses and interpreting echoes to track targets in real time. Some are designed to exploit a ship’s wake—the disturbed water left behind by massive hulls moving at speed—treating it like a trail to follow in darkness.
