in excess of 400 feet
The depth of a submarine under the sea means how many feet below the surface of the sea it is.
The submarine was at a depth of 3,000 feet.
An average submarine is about 300 feet long.
50 ft
An unmaned submarine can go down to 15000
If we have 294 + 1277 here, it will equal 1571 feet. The reference is sea level, and the submarine is 294 feet below it. As the helicopter is at 1277, by adding 294 and 1277, we get the distance between the sub and the chopper, which is 1571 feet.
300 feet
370 feet. At least that is what I think.
Depending on the size of the submarine and whether it is peace or wartime.U-Boat. 27 -> 57Non Nuclear ~ 40Nuclear ~ 80 (more in wartime)
The first submarine was about 46 feet in length and assembled in Barcelona, Spain. The first successful launch of this submarine was in 1864 and held a crew of two people.
No - most military submarines are limited to crush depths above 2,000 feet.
