This is one of the most nonsensical news stories in recent times.
Why would Iran, which already operates UUVs and UAVs weighing up to 9 tons, resort to using dolphins?
The arrival of underwater drones has completely eliminated any need for dolphin programs.
And this happened for obvious reasons.
They lack the programmable precision of a UUV/UAV; they do not obey real-time commands like a drone; they can become disoriented, flee, or simply fail to execute the mission as expected; they tire, feel stress, and their control is based on conditioning rather than software.
All of this has rendered them obsolete.
We have entered a new era, one defined by the large-scale employment of unmanned systems.
An attempt to force the strait open will result in a battle involving technological systems and capabilities never before seen on such a large naval scale.
