After the KR-14D was unveiled not everybody picked up on the United Earth Government's subtlety of maintaining the poor quality. In the United States, the Boez-Maus mecha manufacturing company decided to modify the KR-14 design on their own to produce a superior unit. The project was approved by the CEO and funds were diverted from other areas (delaying the manufacturing plant intended on producing Heavy Axel designs, in one instance).
The KR-14 model was taken, examined, and then modernized with off-the-shelf components that were beginning to appear in the market. The leg joints were given the same ballistics coating that had been seen on such designs as the 97S and in a primitive form on the MN-18. This was because the jackets were becoming something of a standard among mecha designers producing new designs. Other improvements included re-positioning of the cockpit in relation to the arm joints, fixing the body-shoulder pivot points (poorly touched upon in the D model) and many weight-saving measures and materials changes. The unit also incorporated Gloves in the standard design- something not seen on Axel designs in nearly a century. The result was a modernized version of the KR-14.
A pre-production run of twenty units were created to test the capabilities of the new unit, dubbed the KR-14S (for "super", as the unit was intended to be called the "Super Kelleg"). However, when news broke out that Boez-Maus was indeed producing the unit, the United States Government issued a cease-and-desist order against the design and the program. Days later, The UEPC seized the plant and arrested every member of the development team that could be found on the base. They were charged with treason of the state and crimes against the United Earth Government. Months later, due to the embarrassment of the incident and political attacks against the company, Boez-Maus folded completely and was absorbed by the United States' Standard Mech producing company, GM. The plant used to produce the prototype was re-geared to produce KR-14As.
There was never a reason given why such harsh action was taken against Boez-Maus, nor why the unit was come down upon despite being clearly superior to the A and D models. An answer accepted by many Axel enthusiasts and government conspiracy theorists is that the KR-14S model would have reached performance parity of the KR-19- the "enforcer unit" and standard of many core UEG nations. Not only would militaries using the KR-14S have a chance at resisting, but it was an embarrassment to European Axel designers to be upstaged by a small company in the United States.
It is worth noting that of the twenty pre-production units produced by Boez-Maus, only thirteen have been accounted for. Some of the design team was also missing since the cease-and-desist order was received by the Government. It is a common assumption that the team fled with the units to various parts of the world- suspected that as many as five ended up in the hands of the United States 'Cowboy' resistance movement in the southwestern deserts. This lacks direct evidence however, as none of the bandits there have been seen operating the design.
Though the mock-ups were marked 'KR-14S', the UEPC has classified the unit "KR-14P", for Pirate-Model KR-14.
Wanted an excuse to redesign the Kelleg, while channeling Yamashita. I'd like to use the Kelleg for my 3D modeling project, but now I have something like four versions to choose from (A, D, P, and KR-19).
