Diagram of a British, 250 lb General-Purpose Bomb Mark 1, used during the early part of World War 2. A general-purpose bomb is an air-dropped bomb intended as a compromise between blast damage, penetration, and fragmentation in explosive effect. They are designed to be effective against enemy troops, vehicles, and buildings.

The Mark 82 is a 500-pound (230 kg) unguided, low- drag general-purpose bomb, part of the United States Mark 80 series. The explosive filling is usually tritonal, though other compositions have sometimes been used.

Blue Danube was the first operational British nuclear weapon. It also went by a variety of other names, including Smallboy, the Mk.1 Atom Bomb, Special Bomb and OR.1001, a reference to the Operational Requirement it was built to fill.

Suspension in the 1,600 pound AP Bomb Mk 1 design was by means of lugs welded to bands, the bands being positioned by grooves on the external bomb surface. The newer designs, AN-Mk 1 and Mk 33, are suspended by fittings which screw into holes drilled into the bomb case and secured by bolts.

The aerodynamic qualities were first tested at the Dahlgren Proving Grounds in Virginia. A 14/23 scale-model of the weapon was crudely constructed by welding a 14-inch diameter pipe into the middle of a split standard 500-pound bomb. Due to its material construction, it was locally known as the “Sewer Pipe Bomb”.

To trigger the bomb, a conventional explosive forced the two pieces together, instantly creating more than a critical mass. This was called a gun-barrel bomb.

The bomb has parallel sides, with an ogival nose and a slight rear taper, similar in construction to US General Purpose bombs. With the exceptions as given below, exploder containers screw into the nose and base plate. Mk I: fabricated; rolled steel sheet, welded, with nose and tail welded on.

Mk 1 has two sheet steel castings welded together, the bomb having a "tear drop” shape. Mk 4 is a single-piece steel forging; cylindrical, with ogival nose. Mk 1 is horizontally suspended by two lugs welded on the body; it may have single lug or trunnions on the band.

The BLU-110 General Purpose bomb is identical to the MK83 MOD 5 bomb, with the exception of the explosive filler. The primary users are the U.S. Air Force and U.S. Navy. This bomb has a...

The AN-Mk 1 bomb was in United States service during World War II, seeing use sometime prior to 1944. Used between the United States Army and Navy (hence the AN designation), its purpose is to penetrate the horizontal armour of enemy naval ships and detonate below deck.
