(I don't know alot about physics, but i do know the basic stuff)
The dahl favor the idea of firing projectiles without any explosive or volatile substances. They have perfected the style of magnetic acceleration, kinetic acceleration, and energy acceleration.
These three types are utilized in their weapons. Energy acceleration is unique, it launches concentrated masses of energy as projectiles. This allows them to manipulate the type of projectile fired from the weapon. There are three known energy projectiles. Ion, Beam, and Plasma. Ion weapons are used to critically damage electronics or computer systems, its also very affective against shielding and small vehicles.
Beam weapons are mainly melee weapons like beam swords. But they are also utilized in cannons, special massive guns mounted on turrets on only selected crafts. The gun itself is a giant amplifier, the barrel itself has a series of magnifying lenses used to boost the range and damage of the lazer. Beam weapons are great for cutting down fighters, small vegicles, small to medium targets (like missiles or torpedoes), and are great for cutting up thin armor. But since these weapons are a continuos lazer, they soak up alot of energy and are not very affective against large, heavily armored targets. But with a special modifier, the burn trail of the lazer can cause the matter its burned to become so unstable it explodes, causing catastrophic collateral damage.
Plasma weapons are unique, these weapons can manipulate its projectiles to take forms when shot. Its quite malleable for a energy substance. This requires lots of power and dahl blood. Dahlmorian blood has a chamical in the plasma that when extracted can become fuel for their plasma weapons.
The plasma weapon can do very devestating damage to living creatures and armor. The substance will stick and burn like napalm and will burn through at max three to five inches of metal, given what type of metal the target is. The damage is corrosive, and also painful if on bare flesh or clothing.
The way it works is that the blood extracted frommthe user, runs through a process called saturation, the blood is mixed with chemicals and super charged with electricity to activate the plasma, it is then loaded into the weapon system and can be manipulated to desired given projectiles.
Its a more complex process but thats as simple as i can put it.
Next is magnetic acceleration. These are found mounted on ships in turrets. They fire shells using a intense magnetic pulse that will fire the shell at high speeds. This only works in space since there is little to no obstacles to counter act the shell. Also, the barrels have spiral engraves to cause te shell to rapidly spin amongst launch. And since the speed of the shell isn't slowed, the penetration rate is quite high. The lowest penetration rating currently goes at 159in. The highest rating is roughly about 1978in at max.
The penetration ratings have to be high since the armor on the dahl ships are quite thick. And if their own weapons can't take down their heavily armord ships, then that means they have to make new guns with a higher rating.
Most common guns are the MAC variants.
Kinetic acceleration is the strongest in their arsenal. Its used in every high powered gun the dahl have. The most famous are the KAC guns. These guns can tear through at max record of twenty meters of armor. These high powered guns can excede their max penetration record if altered or moded. The guns fire special high velocity shells that aid in penetration. The gun uses a special mechenisim that would seem like a MAC on steroids. The spiral engraved barrel also has special accelerators that amplifies its speed. These guns are the flag ship of dahl weaponry. They can use any type of ammo that can be compatible with KAC guns. The biggest KAC gun can fire rounds as big as the apollo space rocket cut in half. These large shells can have a nuclear, atomic, or anti-matter payloads that deal devastating damage.
The energy intake of all these weapons is massive. It would require six nuclear reactors to fire a single round out of the smallest KAC. But dahl have no problem with power intake with their weapon systems since the reactors they have, has a major pwer output that can overload their systems and even meltdown of not used up.
KAC guns are the biggest, and with the highest penetration rating. MAC guns are fast, efficiant, and reliable with a low power intake. EAC guns have a high poser intake, low damage output without modifiers, and are very expensive to fabricate. But they have special roles that only they can play in.
