When Corean Enterprises was tasked with upgrading the CN-9A Centurion using recovered technology, there was a debate within the research labs and conference rooms. While the proposed CN9-D was impressive, many engineers and technicians were concerned that too much emphasis was given to speed . . . and the use of a (relatively) fragile Extra-Light Fusion engine gave concerns that the new upgrade might prove to be less rugged than the older variants.
Indeed, the Centurion had long been known as a "trooper" 'Mech on the battlefields of the Inner Sphere and Near Periphery. Not the best at delivering raw damage, not the fastest, not the toughest, but good enough in each of these categories to be counted on as a rugged, dependable BattleMech.
Accordingly, Corean offered the AFFS (and the Federated Commonwealth) an alternative design: the CN9-B.
The CN9-B retains the Nissan 200 standard fusion engine of the CN9-A, but incorporates an Endo-Steel II internal structure to save mass. This allowed the design team to add two tons of Star Guard III armor plating, making these new Centurions even more rugged and survivable on the battlefield. The old Luxor AC-10 autocannon was replaced with a Mydron Excel LB-10X Autocannon, saving another ton which the design team used to add Artemis IV Fire-Control Systems to the Luxor 3R LRM-10 launcher. Internally, all ammunition was moved to the right torso which was equipped with CASE (Cellular Ammunition Storage Equipment) increasing the odds of the MechWarrior surviving even in the event of an ammunition explosion. Both Photech 806c Medium Lasers were retained (one still mounted firing to the rear).
Although these were only moderate improvements in weapon range, accuracy, and flexibility, Corean design engineers (and AFFS consultants) believed that the increased survivability and ruggedness of the design were well worth the cost. And without an expensive XL engine, the AFFS could procure more than twice as many 'Mechs for the same expenditure of funds.
The AFFS procurement board was impressed by Corean's arguments, but in the end decided to field test both the CN9-B and CN9-D for further evaluation under combat conditions by veteran MechWarriors. Eventually, it was planned to concentrate production on one design or the other, but the Clan Invasion changed that strategy as the AFFS (and Federated Commonwealth) found it needed every last 'Mech it could produce.
Consequently, the lower-cost CN9-B Centurion can be found throughout the Federated Suns and Federated Commonwealth serving alongside the higher-tech CN9-D and the new Enforcers being produced by Achernar.

The CN9-BH is a similar upgrade to the "Heavy" variant of the Centurion. The Mydron Excel LB-10X Autocannon has been removed and replaced with a Luxor Devastator 20 AC-20 (with three tons of ammunition). To accommodate this heavy weapon, the design team had to removed the Luxor 3R LRM-10 and ammunition, replacing it with a Luxor 3L LRM-5 launcher and a single ton of ammunition (and forgoing the use of Artemis IV FCS). An additional heat sink has been added as well (for a total of 11).

While some MechWarriors love the heavy firepower of this design (especially in an urban environment), many believe that the reduction in range is a fatal flaw. Which is why Corean also introduced the CN9-BG which replaces the AC-20 and extra heat sink with a Poland Main Model A Gauss Rifle. All other weapons remain the same as the CN9-BH.

Next, Corean offered the CN9-BL version for extended operations where ammunition resupply might be problematic. This version retains the Luxor 3R LRM-10 with Artemis IV FCS (and two tons of ammunition for 24 missile salvos) and the two center torso mounted Photech 806c Medium Lasers, but replaces the autocannon with a Blazefire Sweetshot ER Large Laser in the right arm, a Sutel Precision Line Medium Pulse Laser (also in the right arm), two Defiance D5S Small Pulse Lasers (left arm), and a third Photech 806c Medium Laser (in the head). The single heat sinks are replaced with double-strength freezers and three additional heat sinks added. Although still capable of overheating, the margin is minor even on a running Alpha Strike . . . and Corean emphasizes that given the inaccuracy of LRMs at ranges where the Small Pulse Lasers come to bear, it is unlikely that both systems will be used simultaneously. Of course, on the battlefield, most MechWarriors will push their machine to the limits and beyond . . . even if the firing solutions are "iffy", especially when one final weapon strike could mean the difference between victory or defeat.

Finally, Corean introduced the CN9-BL2, which removes the ER Large Laser, the Medium Pulse Laser, and both Small Pulse Lasers to install a Blazefire Doubleshot Binary Laser Cannon in the right arm. Although shorter ranged, this weapon inflicts nearly as much damage as a Gauss Rifle and is favored by some MechWarriors. Especially since this one of the few Inner Sphere weapons that can remove the head of a BattleMech in a single shot, even if it has not been damaged previously. This variant retains the LRM-10 (with Artemis IV) and all three Photech 806c Medium Lasers (one still firing to the rear), along with all thirteen double-strength heat sinks. While some consider the CN9-BL2 to be oversinked, MechWarriors in the field appreciate being able to use the Blazer Cannon without roasting themselves!
