Net explosive wt is a factor...
Fuel Air Explosives will have a larger blast radius; The main destructive force of FAE is high overpressure, useful against soft targets such as minefields, armored vehicles, aircraft parked in the open, and bunkers.
The 550-pound CBU-72 cluster bomb contains three submunitions known as fuel/air explosive (FAE). The submunitions weigh approximately 100 pounds and contain 75 pounds of ethylene oxide with air-burst fuzing set for 30 feet. An aerosol cloud approximately 60 feet in diameter and 8 feet thick is created and ignited by an embedded piezoelectric crystal detonator to produce an explosion.
For those that espouse that Naplam is ILLEGAL, they just changed the Formula and its called INCENAGEL. Same Mk-77 Firebomb cheap aluminum containers.
MK 77 Mod 5 firebombs are incendiary devices with a function identical to earlier Mk 77 napalm weapons. Instead of the gasoline and benzene fuel, the Mk 77 Mod 5 firebomb uses kerosene-based jet fuel, which has a smaller concentration of benzene.
A napalm bomb will cover a pear-shaped area 275 feet long and 80 feet wide. A solid sheet of 1500 degree fire envelops everything, killing personnel, exploding ammunition. It is not a flash fire like gasoline alone would be, but clings and burns and burns.
The real effectiveness of napalm lied in the ability of the bomb to skid along surfaces as it fell, exploding the bomb and spraying the jellied gasoline everywhere. In this manner, even the smallest drop of napalm could set any surface ablaze.

.......Use of aerial incendiary bombs against civilian populations, including against military targets in civilian areas, was banned in the 1980 United Nations Convention on Certain Conventional Weapons Protocol III. However the United States reserved the right to use incendiary weapons against military objectives located in concentrations of civilians where it is judged that such use would cause fewer casualties and/or less collateral damage than alternative weapons........
