Four piper
USS Buchanan (DD-131), 1936
The term four piper is United States Navy terminology for classes of destroyers with four funnels. These include the classes listed below:
- Bainbridge-class destroyer
- Paulding-class destroyer
- Wickes-class destroyer
- Clemson-class destroyer
These classes were built for use by the United States Navy during World War I and subsequently "moth-balled". Fifty were loaned, under Lend-Lease to the United Kingdom when convoy escorts were desperately needed in the early years of World War II.
