Hello everyone! I'm looking for information on the SAP shell of the British 203mm/50 Mark IX and X gun (intended for the heavy cruisers designed after the start of the war).
More specifically, I'm looking for penetration tables and shell schematics of the improved, heavier 290 lbs SAP shell (131.54 kg with an unknown explosive filler weight). According to Campbell in his Naval Weapons of WW2 book, this shell would be fired at 814 m/s (2670 fps), and would have the following ballistic data at what is assumedly the in-service muzzle velocity:
But I lack penetration tables, if they even existed.
I don't even have particularly good pen tables for the earlier Mark VIII gun and its 116kg SAP shell (I only have calculated values from Okun, and some charts from a War Thunder user: https://old-forum.warthunder.com/in...24-8in-bl-mk-viii-gun-sapc-penetration-issue/, https://old-forum.warthunder.com/index.php?/topic/494804-850-mk-viii-wrong-exterior-ballistics/)
Also, a shell diagram like the one for the the old shell below would be nice.
Thanks in advance!
