I couldn’t pass this by, it gives a real perspective re “armour” defences in naval ships of the first half of the 20th century
This 26” thick armour has been breached by a 16* shell!

Got no idea where that armour comes from but it's certainly not a Yamato, no US Battleship ever fired on a Yamato, both were sunk by carrier aircraft.

This was most likely a piece of extra / spare / R&D armor used during testing in Japan before being captured by the US after the Japanese surrender. But this is most likely just a very close range (50 meter?) and 90 degrees hit by a 16 inch shell on this piece of armor so this does not prove much for practical penetration. This sort of data is only useful if you have comparative data under similar test conditions.

I had some time to look this picture up and this short video explains the what and why of this piece of armor.

Thanks for clearing that up, the test was done at 400ft (121m) it is in the video.

Two days ago around 22:30 local time during a night exercise, contact was lost with two JMSDF helicopters near the Izu-islands, 600 km south-east of Tokyo. One body of a crew member has already been recovered, but seven more crew members are still missing.

There is no information in this news article about the type of helicopters, but it was an anti-submarine exercise, so i expect these are two Sikorsky/Mitsubishi H-60 ASW-helicopters.

The two helicopters were near Torishima.

Japan's coastguard service has ordered three more Eurocopter EC225 twin-engine helicopters. This latest order brings the Japan Coast Guard's total EC225 fleet to 18.

Maritime Self-Defense Force helicopter crash: 1 dead, 7 missing

海自ヘリ墜落事故　搭乗員8人の氏名を公表　1人死亡、7人行方不明 | 毎日新聞

　伊豆諸島・鳥島の東海域で海上自衛隊の哨戒ヘリコプター「SH60K」2機が夜間訓練中に墜落した事故で、海上幕僚監部は23日、2機の搭乗員計8人の氏名を公表した。1人が死亡し、7人が行方不明となっている。

On the 23rd, the Japan Maritime Staff Office released the names of the eight crew members involved in an accident in which two SH60K patrol helicopters of the Maritime Self-Defense Force crashed during a night training exercise in the waters east of Torishima in the Izu Islands. One person is dead and seven people are missing.

The two aircraft are "unit 8416" assigned to Omura Air Base (Nagasaki Prefecture) and "unit 8443" assigned to Komatsushima Air Base (Tokushima Prefecture). There were four people on board each, including the captain, co-pilot, and two navigators.

The accident occurred on the night of the 20th in waters approximately 270 kilometers east of Torishima. The two planes were engaged in anti-submarine training, and the Japan Maritime Self-Defense Force believes there is a high possibility that they collided in mid-air.

According to the Japan Maritime Self-Defense Force, the two aircraft belong to Omura Air Base (Nagasaki Prefecture) and Komatsushima Air Base (Tokushima Prefecture). At that time, a large-scale training exercise was being carried out involving eight ships, six helicopters, and one submarine belonging to the 4th Escort Group (Kure City, Hiroshima Prefecture), two of which were the Aegis destroyer "Haguro" and a destroyer. It was installed on "Kirisame". The training was inspected by the escort fleet commander, the top of the escort fleet.
