 Science Fair Projects - Hispano 20 mm cannon
This cannon was based on the earlier Swiss Oerlikon FF S weapons, which Hispano-Suiza manufactured under license HS.7 and HS.9.
The Hispano fired a 130 gram (4½ oz) 20 mm x 110 mm projectile with a muzzle velocity between 840 and 880 m/s (2,755 and 2,888 ft/s), depending on barrel length.
The USAF introduced the M39 revolver cannon to replace the M24, while the Navy instead stuck with the original design with a lighter round for better muzzle velocity in the Colt Mk 12 cannon.

The word "cannon" serves both as the singular singular and plural plural of the noun; "cannons" is generally considered incorrect.
The use of cannon was first recorded in the battle battles of the early 14th century 14th century, for instance, at the siege siege of Metz Metz in 1324 1324, and by the English English against the Scots Scots in 1327 1327.
The military use of cannon declined in the mid-19th century 19th century as fabrication technology improved enough to enable the rifling of gun barrels (which in turn required the introduction of breech loading) and the use of the far more destructive explosive shells.

The next factor is rate of fire, with the Hispano II timing in at 10 rounds a second and the MG-151/20 coming in at 12 rounds a second.
The Hispano was a larger cannon, firing a larger/heavier round, at higher speeds.
The 20x80RB M-Geschoss and the 20x110 (Hispano) HE were rated as about equal; the greater blast effect of the M-Geschoss was countered by the greater penetration and kinetic damage inflicted by the Hispano.

A cannon is also a modern day machine gun with a calibre of 20mm or more (see autocannon).
The definition of a modern 'cannon' is entwined with the term 'autocannon', and is a gun with a bore diameter of 20mm or more, capable of, but not always firing explosive ammunition, and generally possessing an automatic loading system of some kind.
The caliber of a cannon, which is 20mm minimum, has been a de facto standard since WWII, when heavy machineguns of 12.7mm (0.5") and 13.2mm caliber were used side by side with 20mm and larger guns, which, in contrast to the machineguns, primarily used explosive ammunition.

 Aces High BB - Hit rate- cannons vs mg   (Site not responding. Last check: 2007-11-03)
Though in that example, each cannon is a bit heavier than each MG, the higher destructiveness of cannon shells means that the ammo load is a bit lighter, making up for the difference in weapon weight.
Projectile count for the Hispano II goes down slightly, but since each projectile is vastly more destructive with cannon, the Hispano in the end wins in this comparison just as easily as the MG151/20.
Cannons will have more critical hits than MG per round simply because cannons fire stronger rounds.
