Approved Tech LLT-2 Seure-class Cannon

Status
Not open for further replies.
Image Source: none
Intent: To provide a projectile cannon suitable for use on starfighters and similiarly sized vehicles
Development Thread: Revenant of Ages Past
Manufacturer: Lucerne Labs
Model: LLT-2 Seure-class Cannon
Affiliation: Open Market (With Marketplace Purchase)
Modularity: No
Production: Minor Production
Material: ferroceramic casing, laser cannon components, cyrogenic cooling system
Classification: Ship-to-ship
Size: same as heavy laser cannon (counts as 2 on the gun tradeoff list for starfighters)
Length: comparable to standard heavy laser cannon (~2 meters)
Weight: 105 kilograms
Ammunition Type: physical projectiles (30x165mm / Blaster Gas)
Ammunition Capacity: 100 30x165mm rounds (standard starfighter mounting, takes up the place of 1 heavy laser cannon)
Effective Range: same as heavy laser cannon

Rate of Fire: 6 rounds a minute (projectile mode) / (Laser cannon mode: standard light laser cannon fire rate)

Strengths
-Projectile mode effectively penetrates starfighter and vehicle armor and shields well
-Secondary light laser cannon fire mode ensures use even after projectile ammunition runs out


Weaknesses
-Slow rate of fire
-Limited projectile ammunition capacity



Description: The LLT-2 Seure-class Cannon is an upsized version of the one of the ancient Mandalorian Rippers, a series of energy-propelled slugthrowers. The weapon uses Ablative Laser Propulsion[/url] principles, where a light laser cannon is used to turn the rear of the metallic projectile into the plasma which propels the projectile through the barrel at roughly 1.1 km/s, equivalent to other similar weapons. The 30x165mm round fired by the Seure is well-suited to penetrating shields and armor of starships and ground vehicles because of its high velocity, though its relative damage is equivalent to that of a heavy laser hitting an unshielded target. This makes the Seure well-suited for hitting heavy armored and lumbering targets like tanks or dropships. But this power comes at a cost. The high velocities that the slug is subjected as well as the plasma rapidly heat the barrel. Even with extensive cyrogenic cooling systems around the barrel, a projectile can only be fired safely every 6 seconds, though many users wait longer just to be on the safe side. The shells also take up space, limiting the cannon to only carry 100 cartridges (in order to take up the same amount of space as a heavy laser cannon). These drawbacks are somewhat offset in that the pulse laser which ignites the metallic propellant can be selectively fired on its own without any projectile ammunition. In this mode, the Seure acts like a normal light laser cannon. While not a terribly effective against most targets, many Seure users use it extensively to help conserve projectile ammo for decisive attacks.

EDIT: For whatever reason, I can't get several hyperlinks to work in the main paragraph, so here they are:

This idea seems to be thought out well.
Approval Without Development Thread
  • Choose one or the other of your two cannons. Either the slugthrower, or the blaster.
  • Tone down on the speed the ammunition exits the barrel, what is listed on that wookie page is the maximum speed ammunition was capable of being propelled at using that technology. (I am going by the weight of your weapon rather than general size, as you have not included an image or description of its appearance, and a 105kg / 230lb cannon is not going to be firing at the peak of that technology without a significant recoil and stress on the barrel of the weapon.) Or increase the weight of the weapon to 200kg.

  • 10 post development thread that includes the combination of your slugthrower mass driver and the secondary blaster into one piece of technology.

I'll get to work on that development thread then.

Does 1070 meters a second sound all right then for exit velocity? It's about where modern aircraft cannons like the GAU-8 are at...

EDIT: For clarification, I intend to go with lesser exit velocity to keep the weapon's weight and volume down.
