Four piper

The term four piper, also known as a four stacker, 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 the Destroyers-for-bases deal to the United Kingdom when convoy escorts were desperately needed in the early years of World War II.
