There have been many extremely large explosions, accidental and intentional, caused by modern high explosives, boiling liquid expanding vapour explosions (BLEVEs), older explosives such as gunpowder, volatile petroleum-based fuels such as gasoline, and other chemical reactions. This list contains the largest known examples, sorted by date. An unambiguous ranking in order of severity is not possible; a 1994 study by historian Jay White of 130 large explosions suggested that they need to be ranked by an overall effect of power, quantity, radius, loss of life and property destruction, but concluded that such rankings are difficult to assess.
Pumpkin bombs were conventional aerial bombs developed by the Manhattan Project and used by the United States Army Air Forces against Japan during World War II. It was a close replication of the Fat Man plutonium bomb with the same ballistic and handling characteristics, but it used non-nuclear conventional high explosives. It was mainly used for testing and training purposes, which included combat missions flown with pumpkin bombs by the 509th Composite Group. The name "pumpkin bomb" was the term used in official documents from the large, fat ellipsoidal shape of the munition casing instead of the more usual cylindrical shape of other bombs, intended to enclose the Fat Man's spherical "physics package".

Joliet Army Ammunition Plant (JOAAP, formerly known as the Joliet Arsenal) was a United States Army arsenal located in Will County, Illinois, near Elwood, Illinois, south of Joliet, Illinois. Opened in 1940 during World War II, the facility consisted of the Elwood Ordnance Plant (EOP) and the Kankakee Ordnance Works (KNK). In 1945, the two were deactivated and combined forming the Joliet Arsenal. The plant was reactivated for the Korean War and renamed Joliet Army Ammunition Plant during the Vietnam War. Production of TNT ended in 1976, and the major plant operations closed shortly after in the late 1970s. The facility briefly revived an automated load-assemble-pack (LAP) artillery shell operation that was managed by the Honeywell Corporation during the Reagan administration in the 1980s before it was finally closed.
USS LST-519 was an LST-491-class tank landing ship built for the U.S. Navy in World War II. She was later renamed USS Calhoun County (LST-519) after counties in eleven states in the United States.
Operation CHASE was a United States Department of Defense program for the disposal of unwanted munitions at sea from May 1964 until the early 1970s. Munitions were loaded onto ships to be scuttled once they were at least 250 miles offshore. While most of the sinkings involved conventional weapons, four of them involved chemical weapons. The disposal site for the chemical weapons was a three-mile (5 km) area of the Atlantic Ocean between the coast of the U.S. state of Florida and the Bahamas. Other weapons were disposed of in various locations in the Atlantic and Pacific oceans. The CHASE program was preceded by the United States Army disposal of 8,000 short tons of mustard and lewisite chemical warfare gas aboard the scuttled SS William C. Ralston in April 1958. These ships were sunk by having Explosive Ordnance Disposal (EOD) teams open seacocks on the ship after they arrived at the disposal site. The typical Liberty ship sank about three hours after the seacocks were opened.
Holston Army Ammunition Plant (HSAAP) manufactures Research Department Explosive (RDX) and High Melting Explosive (HMX) for ammunition production and development. It is a government-owned and contractor-operated (GOCO) facility that is part of the US Army Joint Munitions Command.

Camp Navajo was originally opened in 1942 in Bellemont, Arizona. It was originally designated Navajo Ordnance Depot, and its primary use was the storage of ammunition used in the Pacific Theater of World War II. It was renamed Navajo Army Depot in 1965, changed to Navajo Depot Activity in 1982, and then changed in 1993 to its current name. In 1993 the Department of Defense transferred all ammunition activities to Hawthorne Army Ammunition Plant in Nevada. Following the transfer, Camp Navajo remained federal land under the Department of the Army, overseen by the Arizona Army National Guard. The Ordnance Operations and Industrial Park are managed by the Arizona Department of Emergency of Military Affairs (AZDEMA), and the military training mission remains managed by the Arizona Army National Guard. All authority is given through the Department of Defense Army Corps of Engineers regarding engineering, design, and construction management processes for potential DoD and DoD type customers.
The Nebraska Ordnance Plant is a former United States Army ammunition plant located approximately ½ mile south of Mead, Nebraska and 30 miles west of Omaha, Nebraska in Saunders County. It originally extended across 17,250 acres (69.8 km2) producing weapons from 1942-45 after which the Army used it as a bomb factory during the Vietnam War. Environmental investigations in the 1980's found the soil and groundwater contaminated with the explosive RDX and the degreaser trichloroethylene. In 1990, federal agencies added the site to the National Priorities List as a Superfund site. Remediation included soil excavation and water treatment, the latter of which has been ongoing since 1997. Water is contained and treated at 4 treatment plants and the known plumes are monitored at hundreds of wells. The latest wells, dug deeper into the bedrock than previously, showed RDX and TCE above desired action levels in April 2016.
