El F-521, también indexado como 53-F-521, es un proyectil soviético de mortero de alto explosivo de 152 mm vinculado al mortero de 152 mm modelo 1931 y a correcciones posteriores de tablas de tiro para el obús de 152 mm modelo 1909/30. La línea de la tabla 1909/30 asigna al proyectil una masa de 38,3 kg, una carga explosiva de 7,7 kg, espoleta RGM-2 y un alcance máximo listado de 8,35 km, mientras que las notas de munición del D-1 excluyen explícitamente el 53-F-521 del disparo con D-1, M-10 y ML-20.

Firing Compatibility

El F-521 debe tratarse preferentemente como un proyectil heredado de mortero de 152 mm, no como una munición genérica de obús D-1. La tabla del obús 1909/30 registra una entrada de tiro 53-F-521 con datos de carga, espoleta, velocidad y alcance, mientras que las notas de munición del D-1 indican que el 53-F-521 no debía dispararse desde el D-1, M-10 ni ML-20.

Entrada de tabla respaldada

La tabla del obús de 152 mm modelo 1909/30 enumera el 53-F-521 con la carga 54-Zh-534, espoleta RGM-2, velocidad inicial de 380 m/s y alcance máximo de 8,35 km.

Contexto de designación

Las tablas de índice GRAU enumeran el F-521 como un proyectil de mortero de alto explosivo, y la National Electronic Library registra una tabla de corrección dedicada de 1946 para el disparo del F-521 desde el obús 1909/30.

Sistemas posteriores excluidos

Las notas del D-1 identifican el 53-F-521 como una excepción cuyo disparo estaba prohibido con D-1, M-10 y ML-20.
