It would make too much noise in the water near the sonar dome and long-range sonars, be impossible to support underwater at high speed as the boat turned, and would not be able to give enough warning to survive anything.

Try attaching a broomstick to the front of your boat (underwater at the bow), and then running at 30+ knots .....

Can't be done.

Even the cleats (which are reversible and retractable) and the hatches and latches and screws and bolts fwd are flush to the hull to reduce noise. There are no handholds anymore forward because they made too much noise. The cleats aft (behind the sail) are streamlined and "too small" to be easily used because they reduce water drag and noise that way.

The sub's navigation lights are streamlined even. It's fog whistle is covered with a retractable cover.

We went into the yards way back when to get the latest; the trailing sonar tail. Only thing, it was not retractable. Our skipper was peeved. As soon as we left Hawaii, he told took the Conn and rigged for angles and dangles. On our next routine transmission, we informed Fleet that we had "lost" our tail and we proceded on for our WestPac.

Can't be easily done passively, my friend...

...But we're Americans. We can do things, actively.

The boat herself has plenty of electrical juice. Run a cable to a small, electrically powered craft that remains some distance ahead of the boat herself.

Let the lead "curb feeler" ram uncharted mountains, and by so doing, give a ballast-blowing computer time to save American lives back in the trailing boat.
