  There was a slight hiccup at the start when he said "in the immediate aftermath of WWII"!  Actually meant WWI as after WWII Japan didn't have a navy but caused me a moment of confusion.

  I suspect the Kii's might not have been completed without the treaty anyway given the strain the programme was inflicting on the Japanese economy even before the 23 quake.

Unless he speaks of World War III in the 1940s.

I watched until 1.05.50 and then looked at the function rate % for shells out for PoW, KGV and DoY in the3irw engagements against Bismarck, Bismarck and Scharnhorst respectively. I was surprised at the fail to function % rates for shots out.  This here from Anthony Williams  had other hard numbers for me to match

The design of this gun was based upon the 12"/50 (30.5 cm) Mark XIV, which was an experimental weapon completed in August 1933 to test "all steel" construction techniques. These new 14" (35.6 cm) guns were to a no-wire, radial-expansion construction, which resulted in a stronger, lighter gun that was less likely to suffer from barrel droop. This improved design gave the British a weapon that was more accurate and had a longer barrel life than the larger 16"/45 (40.6 cm) Mark I. Unfortunately, the mountings for these weapons were prone to mechanical failures during the early part of the war, with both HMS Prince of Wales and HMS King George V having numerous problems during their engagements against Bismarck.



Many, if not most, of these problems had been corrected by 1943. During the early part of her action against Scharnhorst at the Battle of the North Cape on 26 December 1943, HMS Duke of York made 31 straddles out of 52 broadsides fired and during the latter part she made 21 straddles out of 25 broadsides, a very creditable gunnery performance. In total, Duke of York fired 450 shells in 77 broadsides. However,

HMS Duke of York still fired less than 70% of her possible output during this battle because of mechanical and "errors in drill" problems

Interesting. The 30% shots out failure for Duke of York in 1943 was considered an improvement over KGV and the PoW performances in 1941? Can anyone explain this conclusion for me? 

I mean the North Cape battle should be compared to Komandorski Islands. USS Salt lake City, a Pensacola class cruiser, when introduced into service had problems with her guns, feed systems and hoists, when introduced. Famously in Manila Bay pre-war (1937?)_, this problem which affected all of the US Pensacola and Northampton cruisers had been encountered and were unacceptable. Live fire function checks were executed and the mechanicals were sorted out. This cruiser, USS Salt Lake City, shot a 90 minute gun action. We can make a fair comparison. .     
   
PoW's loss was a design flaw in her shaft alleys' pass throughs. One torpedo with a 150 kg warhead sank her. One protects the ship with multiple beam bulkheads. RMS Vittorio Veneto survived because her compartmentation was superior. No excuses here. Bad engineering is the forensic conclusion.
