Napalm in the context of "Firebombing"

Incendiary weapons, incendiary devices, incendiary munitions, or incendiary bombs are weapons designed to start fires. They may destroy structures or sensitive equipment using fire, and sometimes operate as anti-personnel weaponry. Incendiaries utilize materials such as napalm, thermite, magnesium powder, chlorine trifluoride, or white phosphorus. Though colloquially often called "bombs", they are not explosives but in fact operate to slow the process of chemical reactions and use ignition rather than detonation to start or maintain the reaction. Napalm, for example, is petroleum especially thickened with certain chemicals into a gel to slow, but not stop, combustion, releasing energy over a longer time than an explosive device. In the case of napalm, the gel adheres to surfaces and resists suppression.

A brown-water navy or riverine navy, in the broadest sense, is a naval force capable of military operations in inland waters (rivers, lakes and inland seas) and nearshores. The term originated in the United States Navy during the American Civil War, when it referred to Union forces patrolling the muddy Mississippi River, and has since been used to describe the small gunboats and patrol boats commonly used in rivers, along with the larger "mother ships" that supported them.

Brown-water navies are typically only used for patrolling and enforcing internal waters, in contrast to blue-water navies, which can independently conduct operations in the open oceans and project power far offshore. Green-water navies, which operate mainly in brackish estuaries, bays and shallow seas not too far off coasts (typically within the bounds of exclusive economic zones), fill the operational gap between brown-water and blue-water navies.

Aircraft ordnance or ordnance (in the context of military aviation) is any expendable weaponry (e.g. bombs, missiles, rockets and gun ammunition) used by military aircraft. The term is often used when describing the payload of air-to-ground weaponry that can be carried by the aircraft or the weight that has been dropped in combat. Aircraft ordnance also includes air-to-air, anti-ship and anti-submarine weapons.

Some aircraft types can carry a wide variety of ordnance – for example, the Fairchild AU-23 Peacemaker could use forward-firing gun pods, 500 and 250 pound bombs, napalm units, cluster bomb units, flares, rockets, smoke grenades and propaganda leaflet dispensers.

The Mark 77 bomb (MK-77) is a United States 750-pound (340 kg) air-dropped incendiary bomb carrying 110 U.S. gallons (416 L; 92 imp gal) of a fuel gel mix which is the direct successor to napalm.

The MK-77 is the primary incendiary weapon currently in use by the United States military. Instead of the gasoline, polystyrene, and benzene mixture used in napalm bombs, the MK-77 uses kerosene-based fuel with a lower concentration of benzene. The Pentagon has claimed that the MK-77 has less impact on the environment than napalm. The mixture reportedly also contains an oxidizing agent, making it more difficult to put out once ignited, as well as white phosphorus.
