Type-15 Triple-Barrel Rotary Point-Defense Cannon

The Type-15 Triple-Barrel Rotary Point-Defense Cannon, officially the Arkanian Heavy Engineering Type-15 Triple-Barrel Rotary Point-Defense Cannon and simply known as the Type-15, is a type of point-defense cannon manufactured by Arkanian Heavy Engineering at Arkania Shipyards and other manufacturing facilities. 
The Type-15 is the standard point-defense cannon used on Arkanian starships for defending against projectiles, starfighters and other small craft and has been used on all Arkanian starships from Generation 5 onwards. It has defended Arkanian starships and ships of other nations throughout many battles and has proved to be an effective defensive weapon.
== Development ==
The Type-15 Point-Defense Cannon was developed from the Terran Republic-era Type-14 Point-Defense Cannon. Though similar in appearance to the Type-14, the Type-15 has more modern sensors, updated rotary guns and other equipment.
The development of the Type-15 began in 2035 after the foundation of the Second Arkanian Republic and the Arkanian Republic Navy. The ARN requested a design for a new point-defense cannon which would replace the Type-14s and be used on the newest generation Arkanian ships which were under development at the time. The Type-15 was born out of overhauls and upgrades to the Type-14.
== Variants and Derivatives ==
=== Type-15B Triple-Barrel Rotary Point-Defense Cannon ===
The Type-15B is an upgrade of the original Type-15 and began usage on Arkanian ships beginning with Generation 6. It is a slight update, with an updated barrel and sensors.
=== Type-16 Dual-Barrel Rotary Point-Defense Cannon ===
The Type-16 is a derivative of the standard Type-15. The Type-16 is a smaller, remote-controlled variant of the
Type-15 with one barrel removed. The Type-16 was first used on the joint DEMC-Gewurz CR-O Omega Light Transport Ship and is to be used on smaller Arkanian-designed starships which would not be able to accomodate the larger Type-15.
