Roosevelt
President Carter had been a submarine officer, nuclear qualified, but never actually was the commanding officer on a submarine.
President Dwight D. Eisenhower was the first sitting President to dive on board a nuclear submarine. On September 26, 1957, he took a 15 minute dive aboard USS Seawolf (SSN-575). Jimmy Carter was a submarine officer, before he was president and saw active duty on them from 1948 to 1952 including service on one of the first nuclear subs. The first president reported to travel in a submarine was Teddy Roosevelt, but I do know if he was president then or if the submarine submerged with him on board.

The first president to travel in a submarine was Teddy Roosevelt.President Dwight D. Eisenhower was the first President to dive onboard a nuclear submarine. On September 26, 1957, he took a 15 minute dive aboard USS Seawolf (SSN-575).It was claimed Theodore Roosevelt. it should be noted James Earl Carter was a submarine officer, (not as president) and while he never commanded a submarine, did see active duty on them.
I think Theodore Roosevelt was the first to ride in a car, but it was before he was president. McKinley was the first sitting president to ride in a car.
The first President to ride a train was Andrew Jackson. He rode what was known as the iron horse from Baltimore.
Harry S. Truman
It was President Jimmy Carter who served in the U.S. Navy, and aboard submarines. He was a crew member of the nuclear submarine SSN-575, the USS Seawolf.
