BB engine room hit by 4in gun

[EwaldvonKleist]

Not sure if this is WAD. Heavily armed battleship's engine room is hit by 4in gun over 6k yards. Isn't the engine room part of the protected part of the AON scheme?

And even if it is not part of the AON part, how does a 4in shell reach the engine room that always is in the centre of the ship?

We'll take a look.

The 4" shell didn't penetrate the B armour, as a * denotes armour penetration - i.e. it would say B*.

However, an earlier (0858) 4" shell damaged the uptakes which has caused the loss of speed observed.

[Searry]

Yes it did not penetrate.

[EwaldvonKleist]

So the game assumes a part of the length of the ship is "engine room" and penetration is simply tested against the engine room section of the ship?

For IRL a 4in shell would never get near the engine room of a heavy BB, but of course can hit the outer belt several metres away from the engine room in the "engine room section" of the ship's full length.

[WLRoo]

Pretty much this.

My best guess is that the game:

Rolls to hit

If successful, rolls for hit location

Rolls for penetration

If successful, rolls for effect
