The X-1 (also known as SS X-1) was a special small submarine built for the United States Navy. It was designed to be a "midget submarine." Construction began on June 8, 1954, in Deer Park, New York. The submarine was launched into the water on September 7, 1955. It was given to the Navy on October 6, 1955, and officially started its service on October 7, 1955. Lieutenant Kevin Hanlon was its first commander.

Exploring the X-1 Submarine's Purpose

The X-1 submarine was used for important research. The Navy wanted to learn how to protect harbors from very small submarines. They also used the X-1 to understand what these tiny submarines could do. These tests helped the Navy prepare for different kinds of underwater challenges.

How the X-1's Engine Changed

When it was first built, the X-1 used a special engine system. It ran on hydrogen peroxide and a diesel engine, along with batteries. However, on May 20, 1957, there was an explosion involving its hydrogen peroxide supply. Because of this, the submarine was changed to use a different type of engine. It was then powered by a diesel-electric system. On December 2, 1957, the X-1 was taken out of service in Philadelphia.

X-1's Return to Service

In December 1960, the X-1 was moved to Annapolis, Maryland. It was put back into service and joined Submarine Squadron 6. The submarine was based at the Severn River Command and used for new experiments in Chesapeake Bay. Scientists from the Naval Research Laboratory used the X-1 for their studies. They watched its operations from a platform under the Bay Bridge. This helped them learn more about how seawater behaves.

The X-1's Final Journey

The X-1 continued to be active until January 1973. On February 16, 1973, it was taken out of service again. A few months later, on April 26, 1973, it was moved to the Naval Ship Research and Development Center in Annapolis. On July 9, 1974, it was decided that the X-1 would become a historical exhibit. It was displayed at the Naval Station complex near Annapolis for many years. In 2001, the X-1 was moved to the Submarine Force Museum in Groton, Connecticut. Today, you can see it on display there, right in front of the main museum building.

The X-1 as a Toy

The X-1 submarine even inspired a toy! The Lionel 3330 "Commando" submarine toy was designed based on the look of the real X-1. You can learn more about it on the LIONEL TRAINS 3330 website.
