Admittedly, you are no expert. Neither am I, but the question I have is:

How often is the gun used to strafe ground targets in the first place?

the gun isn't used much, there isn't much point to wasting the
space/weight,
is there?


The same sort of reasoning was applied to the lifeboats on the
Titanic......

which weren't much use as most people didn't get to them in time anyway...

Which was a failure of organisation, not of the boats themselves. Except for
the last couple of collapsible lifeboats all of Titanic's boats were
successfully launched in sufficient time, but owing to poor regulations and the
lack of any lifeboat drill many were only partly full. IIRR they held something
like 700 of the 1,100 or so they could have.
