The USS Albacore (AGSS 569) is an experimental research submarine that pioneered the American version of the “teardrop” shaped hull typical of most modern submarines.
The ship was commissioned in 1953 and underwent extensive testing, after decommissioning it was put on permanant display in Portsmouth, New Hampshire in 1985.
The sub and museum are easily acessable just of the Route 1 bypass with parking and a museum next to the sub.
There are memorials to the sailors who lost their lives on ships commissioned in New Hampshire at the Portsmouth Naval Shipyard.
There is a self guided tour to the interior of the submarine.
An interesting piece of nautical history and be sure to check out the rest of Portsmouth while in the area.
