CSS David with spar torpedo

Drawings of the CSS David, a 50-foot steam torpedo boat of "cigar-shaped" hull design. The top drawing shows the ship's spar torpedo, a bomb placed at the end of a spar (a long pole). The ship would run the spar into an enemy vessel, leaving the explosive in place. When the attacking ship backed off, the bomb would trail a long detonator cord, and when the end of the cord was reached, the bomb would detonate.

Public Domain

Public Domain is a copyright term that is often used when talking about copyright for creative works. Under U.S. copyright law, individual items that are in the public domain are items that are no longer protected by copyright law. This means that you do not need to request permission to re-use, re-publish or even change a copy of the item. Items enter the public domain under U.S. copyright law for a number of reasons: the original copyright may have expired; the item was created by the U.S. Federal Government or other governmental entity that views the things it creates as in the public domain; the work was never protected by copyright for some other reason related to how it was produced (for example, it was a speech that wasn't written down or recorded); or the work doesn't have enough originality to make it eligible for copyright protection.
