Double Zero
The weapon systems of today's warships are less reliant on centralised computer systems and are therefore less susceptible to being put out of action by limited action damage such as having cabling cut by cannon fire.
One of the factors in the loss of both
Sheffield and
Coventry was the fact that they had been fitted with old radar systems, furthermore the Argentines also had Type 42s, so they could practice dodging radar detection by lobe pecking and other methods. The Type 45 has a brand new radar that is really state of the art -
Sampson. Because the beam will be electronically steered, predicting the lobe pattern will be impossible.
Unless you were talking about the big(ish) gun on the foc'sle?
