The MP-57 is a Submachinegun and has been used by the Royal Lyngaardian Armed Forces since 1957. Adopted to replace the Model 30 Submachine Gun in army service. Desisgned to be used by vehicle crews, security, and special forces, the MP-57 was widly adopted within the army and has seen success in foreign markets. The MP-57 was designed by Eugène Fønss, commander of the 3. Marinekommando Brigade with the intent of creating a lightweight, manuverable, and simple firearm for use by soldiers. The firearm was manufactured by the Guldbæk & Kjer Group with several variants in prooduction.
History
The MP-57 was made by Eugène Fønss to fill in a gab he felt existed in infantry capabilities. During decolonialization conflicts in Mauria he noticed that the forces he commanded lacked effective mobile fire to supress enemy forces, using the Tjenestegevær 05 and the ISMG 20 Machine gun saw forces being unable to move and attack effectively. While Lyngaardian forces did use the Model 30 Submachine Gun it was commonly meligned for being too heavy, too long, and unreliable. When Fønss returned home he set out to design a better infantry fighting weapon.
Fønss would make several prototypes in his back yard, by his 3rd prototype he had also started writing for Jægeren Månedlig. He would make articles detailing his work monthly. this would get the attention of Karl Wiehe
