The Double Eagle is a remotely operated vehicle (ROV) built by the Swedish defence company Saab Underwater Systems AB and used for the disposal of naval mines.

A double eagle is a gold coin of the United States with a denomination of $20. (Its gold content of 0.9675 troy oz (30.0926 grams) was worth $20 at the 1849 official price of $20.67/oz.) The coins are made from a 90% gold (0.900 fine = 21.6 kt) and 10% copper alloy and have a total weight of 1.0750 troy ounces (33.4362 grams).

The "eagle", "half eagle", and "quarter eagle" were specifically given these names in the Act of Congress that originally authorized them ("An act establishing a mint, and regulating coins of the United States", section 9, April 2, 1792). Likewise, the double eagle was specifically created as such by name ("An act to authorize the coinage of gold dollars and double eagles", title and section 1, March 3, 1849).

The first double eagle was minted in 1849, coinciding with the California Gold Rush. In that year, the mint produced two pieces in proof. The first resides in the Smithsonian Institution in Washington, D.C. The second was presented to Treasury Secretary William M. Meredith and was later sold as part of his estate—the present location of this coin remains unknown.

In 1850, regular production began and continued until 1933 (when the official price of gold was changed to $35/oz by the Gold Reserve Act). Prior to 1850, eagles with a denomination of $10 were the largest denomination of US coin. The $10 eagles were produced beginning in 1795, just two years after the first U.S. mint opened. Since the $20 gold piece had twice the value of the eagle, these coins were designated "double eagles". In 1850, the double eagle had the purchasing power of $1200 today.

Double Eagle was a helium balloon piloted by Ben Abruzzo and Maxie Anderson in a failed attempt to cross the Atlantic Ocean in 1977. It was the eleventh recorded attempt to make the crossing, which had been an open challenge in ballooning for more than a century. The balloon launched from Marshfield, Massachusetts on September 9. After being blown off course by stormy weather, the team was forced to ditch three miles off the coast of Iceland on September 12, 65½ hours after taking off. Abruzzo and Anderson, along with Larry Newman, went on to complete the first successful Atlantic crossing the following year aboard Double Eagle II.

Double Eagle was designed by Ed Yost and had a 101,000 cubic foot (2,860 cubic meter) envelope. Abruzzo and Anderson rode in an insulated open gondola measuring 6 by 6.5 feet (1.8 by 2 meters) which was later reused for Double Eagle II.
