A submarine, theoretically, can go as long as the food for its sailors last. A submarine can make oxygen, distill water, remove CO2 and other pollutants, and provide almost anything needed to survive at sea and underwater for nearly an indefinite period of time. Modern nuclear-powered submarines' reactors will last without refueling for the life of the submarine - about 20 years. In 1960, the nuclear-powered submarine USS Triton circumnavigated the globe submerged.

The longest distance you can travel without refueling on land depends on the vehicle's fuel efficiency and tank size. For most cars, it's around 400-500 miles. Specialized vehicles like long-haul trucks may have ranges exceeding 1,000 miles on a single tank. Factors like driving conditions, speed, and load can also impact the distance traveled without refueling.

Around the earth once before it needs refueling.
An average submarine is about 300 feet long.
A nuclear powered submarine can remain submerged for as long as it has fuel rods and supplies for the crew.
No. The submarine came about long before the helicopter.
