At 0847 "Rodney" opened fire...at a gun range of 23500 yards, followed by "King George V" one minute later at 24,600 yards... Initially she did well achieving 1.7 salvoes per minute while employing radar control but she began to suffer severe problems from 0920 onward [Note: KGV had opened fire at 0848 and fired for about 25 minutes at 1.7 salvoes per minute until 0913, when the type 284 radar broke down, but with no recorded loss of 14 inch gun output until 0920.. KGV recorded 14 straddles out of 34 salvoes fired from 0853 to 0913, when using her type 284 radar for ranging and spotting. 'A' turret was completely out of action for 30 minutes 0920, after firing about 23 rounds per gun, due to a jam between the fixed and revolving structure in the shell room and Y turret was out of action for 7 minutes due to drill errors... Both guns in B turret, guns 2 and 4 in A turret and gun 2 in Y turret were put out of action by jams and remained so until after the action – 5 guns out of 10! There were a multitude of other problems with mechanical failures and drill errors that caused delays and missed salvos. There were also some misfires – one gun (3 of A turret) misfired twice and was out of action for 30 minutes before it was considered safe to open the breech.
