Churchill-class submarine
The three Churchill class, sometimes known as the Repeat Valiant-class submarines were nuclear-powered fleet submarines which served with the Royal Navy from the 1970s until the early 1990s. The Churchill class was based on the older Valiant class, but featured many internal improvements.
