Unfortunately, the strong underwater currents proved too difficult and the L24 still lies where she sank. In October 1945, L23 was the last L boat to be taken out of service - 28 years after she was laid down - thus reflecting the success of the class.
The building of the L boats led to the construction of the L50 Class, which was the L Class modified to give increased armament. Although none were built at Vickers, a total of 25 L50 submarines were ordered from seven yards, but of these only seven were completed.
