John P. Cromwell attack technique on order

However, you should be able to use the TDC component of the PK to get the firing solution without having to draw things on the map. I know you dispatched with all that in your simplified DO'K method.... but there was a time when I mentioned that you should use the TDC component of the PK to calculate the intercept angle for you.

I asked earlier how your method is meant to work, but I didn't get an answer, the link you give doesn't show enough of the previous discussion for me to understand it. Do you put in 7 knots regardless of the target speed, or the target speed? Could you please give a brief explanation of using the TDC to get the firing bearing for a zero gyro angle shot?

I believe my exact same suggestion can be followed in this case only instead of a 20° bearing with a 70° AoB, it's 20° bearing and 35.5° AoB (or just 36°)

I tried that and it doesn't work. It missed by miles. Where are you getting 35.5 degrees from?

The nod to O'Kane was merely acknowledging his recording of the tactic, that both he and Morton used, which involved overriding the PK tracking and firing as points of interest passed the wire. Same thing here...

That's not quite right. The method O'Kane used, by holding the bearing on the TDC is not the same as turning the PK off.

I didn't forget to use the TDC... It's also not a case of not bothering with the TDC. If I could use the TDC to find an accurate firing bearing for a zero gyro angle in a simple way, without having to re-enter information, then I would use it. My aim is only to get a firing bearing for a zero gyro angle shot so that range is not important. I also wanted to get an exact 45 degree torpedo track angle. If you can show me a way to get that from the TDC, I'd probably use it. It's only a couple of lines, it's not like you have to complete a 3d sketch of the ship you are shooting at.

Yes, you can get an innacurate solution whose innacurasy doesn't matter because you are shooting from 800 yards, but if you are shooting from 800 yards, you might as well just shoot with a lead angle of speed + 3 degrees with zero gyro angles.
