Just a quick video show casing the new implementation of main batteries with individual barrels firing in succession, each delayed in a few milli-second from another.
"In practice, particularly with turrets having closely spaced guns, the flight of projectiles closely in parallel a few feet apart could affect accuracy with the air wake over long ranges. They found that delaying some of the guns 20 or 30 msec would improve the accuracy. This was done automatically on some guns on some ships. But for spotting and effect, and appearances, it was pretty much simultaneous."
"the guns could be fired individually and that, even during ‘full battery salvo’ firing, it was practicable - certainly by the late part of the Second World War - to fire the guns ‘together’ with a very brief interval between the barrels in each gunhouse (turret). This helped to reduce the dispersal of shells over long distances."
I'll just put a download link here for anyone who interested:
