The Soviet towed corps artillery gun M-46, caliber 130 mm, which is used by Russian military personnel, demonstrates phenomenal results. This was pointed out by military expert Evgeny Damantsev.
Possessing a barrel channel length of 58 calibers, these howitzers are distinguished by the highest muzzle energy, providing a range of standard high-explosive fragmentation projectiles 53-OF-482M of about 27,490 m, and rocket-assisted projectiles with bottom gas generators HE BB — up to 44,000 m
According to him, engineers at the Tula KBP were developing an experimental guided artillery projectile "Firn-1" for the M-46. It was expected that its range would be 24 km, and the range of subsequent modifications, if equipped with a booster unit with a bottom gas generator, would be up to 45 km.
