− | The ''' | + | The '''autocannon/20''' was a direct-fire ballistic weapon, firing HEAP (''H''igh-''E''xplosive ''A''rmor-''P''iercing) rounds at targets either singly or in bursts. |
− | Different manufacturers and models of autocannons | + | Different manufacturers and models of autocannons had different calibers (25 mm–203 mm) and rates of fire. Due to this, autocannons were grouped into generic "classes" of similar common damage ratings, with autocannon/20s doing massive damage while having very short range.<ref name="TMp207+">''TechManual'', p. 207</ref> |
− | This autocannon class | + | This autocannon class could decapitate any [['Mech]] with one good hit to the head, regardless of the weight class, as that location could not mount little more than half a ton's worth of standard armor. The AC/20 was capable of ripping nearly a ton and a quarter of armor off a 'Mech in any given volley (or shot, based on the model). This was enough damage to take down even the heaviest of 'Mechs, if aimed well. Only [[hardened armor]] or [[ballistic-reinforced armor]] could save a [[MechWarrior]] from a hit from this class of cannon to the head. |
− | + | As an example of the rating system, the Crusher Super Heavy Cannon was a 150 mm weapon firing a ten-round cassette in a ten-second period, while the ChemJet Gun was a 185 mm weapon firing a four-round cassette in the same period. As both weapons were capable of firing 200 kilograms of ammunition in a 10-second period, at an effective range of just under 300 meters, they were both classified as autocannon/20s.<ref name=ER3052p98>''Era Report: 3052'', p. 98, "Regarding Military Technology Classification"</ref> | |

− | The titanic ChemJet Gun | + | The titanic 185 mm ChemJet Gun used a popular propellant system that mixed two chemicals in suspension, to propel its four-round bursts from the barrel. This produced an enormous amount of heat, to the point that, on the Mk I model of the Demolisher tank, the crews had to wear special coolant suits; the later Mk II version solved this problem by channeling most of the ejection gases through the barrels.<ref name=TRO3039-86>''Technical Readout: 3039'', p. 86, "Demolisher Heavy Tank</ref><ref name=ER3052p98/> |

Description[edit]
The autocannon/20 was a direct-fire ballistic weapon, firing HEAP (High-Explosive Armor-Piercing) rounds at targets either singly or in bursts.
Different manufacturers and models of autocannons had different calibers (25 mm–203 mm) and rates of fire. Due to this, autocannons were grouped into generic "classes" of similar common damage ratings, with autocannon/20s doing massive damage while having very short range.[2]
This autocannon class could decapitate any 'Mech with one good hit to the head, regardless of the weight class, as that location could not mount little more than half a ton's worth of standard armor. The AC/20 was capable of ripping nearly a ton and a quarter of armor off a 'Mech in any given volley (or shot, based on the model). This was enough damage to take down even the heaviest of 'Mechs, if aimed well. Only hardened armor or ballistic-reinforced armor could save a MechWarrior from a hit from this class of cannon to the head.
As an example of the rating system, the Crusher Super Heavy Cannon was a 150 mm weapon firing a ten-round cassette in a ten-second period, while the ChemJet Gun was a 185 mm weapon firing a four-round cassette in the same period. As both weapons were capable of firing 200 kilograms of ammunition in a 10-second period, at an effective range of just under 300 meters, they were both classified as autocannon/20s.[4]
Ammunition[edit]
A standard AC/20 could fire multiple types of ammunition, most of which were developed by the Federated Commonwealth in order to make their large supply of standard autocannon more useful in the age of ultra and LB-X autocannon.[5]
Models[edit]
The autocannon/20 was manufactured on the following planets:
Armstrong[edit]

Bryant | HartfordCo Industries | Von Luckner | [6] |
ChemJet Gun 185mm[edit]
The titanic 185 mm ChemJet Gun used a popular propellant system that mixed two chemicals in suspension, to propel its four-round bursts from the barrel. This produced an enormous amount of heat, to the point that, on the Mk I model of the Demolisher tank, the crews had to wear special coolant suits; the later Mk II version solved this problem by channeling most of the ejection gases through the barrels.[7][4]

Luxor Devastator-20[edit]
Examples of the 120 mm[25] Luxor Devastator-20 gained a reputation being extremely prone to jamming on the early test models of the AXM-1N Axman; the designers ultimately came up with an alternate LRM-15-armed AXM-2N variant.[26][27][28]

Scarborough Original 20[edit]
Originally developed by Scarborough Limited, though the Scarborough Original 20 autocannon did experience some initial developmental problems, the resulting weapon was equivalent to 200 mm autocannons produced by other companies in the massive amount of damage it inflicted.[42][43]
