The 5.7 x 28 caliber, designed for cases where the 9mm parabellum was inefficient, has already been standardized by NATO-Noticias

The 5.7×28 caliber is a caliber for pistols and submachine guns that was developed in the early 1980s by the Belgian company FN Herstal as a solution to the generalization of personal protection that made the 9 mm caliber inefficient. Parabellum for pistols and submachine guns. Given these combat needs, he began developing this caliber and, at the same time, two weapons designed to exploit his capabilities, the Fine Seven pistol and the P90 submachine gun, or the Personal Defense Weapon (PDW), which has since been widely used among the police and military.

The North Atlantic Organization (NATO) has now recorded the 5.7 x 28 mm caliber. from IFN Herstal as a standardized caliber that is included in the STANAG 4509 standard. In practice, the standardization of the 5.7×28 caliber implies that the armed forces of the Alliance have a guarantee that the ammunition of different manufacturers is interchangeable and of different efficiency in weapons

NATO has thus completed the standardization process for calibers and published the standardization agreement STANAG 4509, which was included in the document for the manual and inspection for multiple calibers (AEP-97), similar to the 9 x 19 mm calibers. NATO, the 5.56×45 mm. NATO, 7.62 x 51 mm. NATO and the 12.70×99 mm. BORN.

This standardization also offers a new alternative in the pistols and machines categories that implement the requirements of the LCGDSS (Land Combat Group Dismounted Soldier System) of the NATO Army Armament Group, as in the document NEW NATO INFANTRY SMALL ARMS POST 2025 (New light weapons for NATO infantry after 2025). Obviously, the Belgian manufacturer supports the inclusion of its Five-Seven pistol and the P90 submachine gun as the first weapon nominated for testing.

So it happens that FN Herstal is also the designer of two of NATO’s most important standardized calibers, such as: B. 5.56 x 45 mm. and 7.62 x 51 mm, standardized in 1,981 and 1,981 respectively. (Jos M Navarro Garca)
