Considering no one has made a claim about ancient submarines, you might be looking for a while.
This is one of the many reasons I think people should read the Book of Mormon instead of relying on what people who lie about the Book of Mormon say.
To carry the Jaredites across the ocean, "barges" resembling ancient submarines were constructed under the continual direction of the Lord (2:6,16). Verse 17 describes their appearance:
"And they were built after a manner that they were exceedingly tight, even that they would hold water like unto a dish; and the bottom thereof was tight like unto a dish; and the ends thereof were peaked; and the top thereof was tight like unto a dish; and the length thereof was the length of a tree; and the door thereof, when it was shut, was tight like unto a dish."
Immediately the brother of Jared noticed vision, steering, and ventilation problems with God's design. He complained:
"O Lord, in them there is no light; whether shall we steer? And also we shall perish, for in them we cannot breathe, save it is the air which is in them; therefore we shall perish" (2:19).
To solve the problem of ventilation, God suggests making a "hole in the top, and also in the bottom; and when thou shalt suffer for air thou shalt unstop the hole and receive air. And if it be so that water come in upon thee, behold, ye shall stop the hole, that ye may not perish in the flood."
