Dahlgren guns were muzzle-loading naval artillery designed by Rear Admiral John A. Dahlgren USN, mostly used in the period of the American Civil War. Dahlgren's design philosophy evolved from an accidental explosion in 1849 of a 32 lb (14.5 kg) gun being tested for accuracy, killing a gunner. He believed a safer, more powerful naval cannon could be designed using more scientific design criteria. Dahlgren guns were designed with a smooth curved shape, equalizing strain and concentrating more weight of metal in the gun breech where the greatest pressure of expanding propellant gases needed to be met to keep the gun from bursting. Because of their rounded contours, Dahlgren guns were nicknamed "soda bottles", a shape which became their most identifiable characteristic.

USS Dahlgren (DD-187/AG-91) was a Clemson-class destroyer which served in the United States Navy during World War II. Entering service in 1920, the ship had a brief active life before being placed in reserve in 1922. Reactivated in 1932, Dahlgren remained in service mainly as a test ship until 1945. She was sold for scrapping in 1946. She was named for Rear Admiral John A. Dahlgren (1809–1870), and was the second ship of three which served in the US Navy to receive the name.

The United States Naval Surface Warfare Center Dahlgren Division (NSWCDD), named for Rear Admiral John A. Dahlgren, is located in Dahlgren, Virginia, with a geographically separated command, Naval Surface Warfare Center Dahlgren Division Dam Neck Activity (NSWCDDDNA), located in Virginia Beach, VA, in close proximity to the largest fleet concentration area in the Navy. NSWCDD is part of the Naval Surface Warfare Centers under the Naval Sea Systems Command (NAVSEA). The NSWCDD was initially established 16 October 1918 as a remote extension of Maryland's Indian Head Proving Ground used for testing naval guns. The Dahlgren site was named the Lower Station, Dahlgren Naval Proving Ground when it first opened. The location on the Potomac River was specifically chosen for the development of a long ballistic test range on the Potomac River, required for the testing of modern, high-powered munitions.
USS Roanoke was a wooden-hulled Merrimack-class screw frigate built for the United States Navy in the mid-1850s. She served as flagship of the Home Squadron in the late 1850s and captured several Confederate ships after the start of the American Civil War in 1861. The ship was converted into an ironclad monitor during 1862–63; the first ship with more than two gun turrets in history. Her conversion was not very successful as she rolled excessively and the weight of her armor and turrets strained her hull. Her deep draft meant that she could not operate off shallow Confederate ports and she was relegated to harbor defense at Hampton Roads, Virginia for the duration of the war. Roanoke was placed reserve after the war and sold for scrap in 1883.

Madeleine Vinton Dahlgren was an American writer, translator, and anti-suffragist. Her volume, Idealities was her first work in book form. Thereafter, she found time to write upon a great variety of subjects. She made several translations from the French, Spanish and Italian languages, notably Charles Forbes René de Montalembert's brochure, "Pius IX," the abstruse philosophical work of Juan Donoso Cortés from the Spanish, and the monograph of Adolphe de Chambrun on "The Executive Power". These translations brought her positive recognitions, among others, a flattering letter from Montalembert. She was the author of a voluminous Biography of Admiral Dahlgren, and a number of novels including South-Mountain Magic, A Washington Winter, The Lost Name, Lights and Shadows of a Life, Divorced, South Sea Sketches (Boston), and a volume on Etiquette of Social Life in Washington, Thoughts on Female Suffrage, and also of a great number of essays, articles, reviews and short stories written for papers and periodicals.
