Montaje naval QF 4 inch

Montaje artillero naval QF 4 inch

Mk XVI

El QF 4 inch (101.6 mm) era el montaje antiaéreo estándar de doble propósito para todos los navíos de la Commonwealth. El Mk XVI venía a sustituir al anterior QF 4 inch Mk V que estaba en servicio en la Royal Navy durante los años finales de 1930 y principios de los años 40. Estos cañones se instalaban normalmente en montajes dobles HA/LA Mk XIX aunque en las fragatas y corbetas australianas estos montajes eran simples (Mk XX). Su vida operativa se prolongó hasta los años cincuenta.

El sistema permitía una elevación máxima de +80º y una depresión de -10º para batir blancos muy próximos pudiendo utilizar proyectiles de alto explosivo de 15´88 Kg o SAP de 17´35 Kg. Los proyectiles podían alcanzar una velocidad de salida de 811 m/s con un alcance efectivo de 15.000 metros.
