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.
A foot long submarine sandwich is 0.000189393939 miles long.
For Safety Checks and Refueling
An F-15 can typically stay aloft for about 2 to 4 hours without refueling, depending on its mission profile, payload, and speed. The exact duration varies based on factors like fuel load, operational conditions, and whether it is engaged in combat or flying at cruising speeds. In practice, air-to-air refueling significantly extends its flight time, allowing for prolonged missions.

An average submarine is about 300 feet long.
The Boeing 777 has a range that varies by model, but the 777-200LR, for example, can fly approximately 15,843 kilometers (about 9,844 miles) without refueling. This long-range capability allows it to connect distant international destinations. Other models, like the 777-300ER, have slightly shorter ranges due to differences in design and capacity.
