The U.S. Navy in England passed a milestone this week when the leadership of the unit Commander, U.S. Naval Activities United Kingdom changed hands for the final time.

In a ceremony at RAF Daws Hill on Wednesday, outgoing commander Capt. Stephen Matts handed off charge of the unit to Capt. David Dittmer, who will head the CNAUK until it is “disestablished,” a spokesman for the Navy in the U.K. said.

The Navy’s presence in the U.K. has been diminishing following the move of U.S. Naval Forces Europe to Naples, Italy, and Wednesday’s event heralds the end of the unit’s 41-year run in England.

No date for that disestablishment, however, has been set yet, the spokesman said.
