Japanese AA Weapon?

Did the Japanese battleship Yamato ever fire an AA salvo during WW2?

A visiting friend of mine in the Navy told me the Japanese had a
battery-fired AA weapon that was actually fired in battle.

I guess it didn't work as the ship was sunk!

Anyone know what this weapon was?

From
http://www.warships1.com/Weapons/WNJAP_18-45_t94.htm

"As were most Japanese warships, the Yamato and Musashi were provided with a
special anti-aircraft incendiary shrapnel shell officially designated as
"Type 3 Common" but nicknamed "San Shiki" (The Beehive). This round weighed
2,998 lbs. (1,360 kg) and was filled with 900 incendiary tubes made out of
rubber thermite and 600 steel stays. A time fuze was used to set the
desired exploding distance, usually about 1,000 meters (1,100 yards). These
projectiles were designed to burst in a 20 degree cone extending towards the
oncoming aircraft with the projectile shell itself being destroyed by a
bursting charge to increase the quantity of steel splinters. The incendiary
tubes ignited about half a second later and burned for five seconds at 3,000
degrees C, producing a flame about 5 meters (16 feet) long. "

Hi

The Yamato had the following weapons dedicated for the anti-aircraft role

Six pairs of 5 inch guns

Twelve pairs of 25 mm guns

Four pairs of 13 mm guns

Cheers...Chris

I think I have identified the source of confusion here. The big guns
on the Yamato are referred to as 'the main battery'. This is a term
stemming from the old sailing ships. So when you hear someone casually
mention 'the main battery fired antiaircraft shells' one unfamiliar
with the term might assume a battery-activated antiaircraft gun. BTW
those San-Shiki shells were used but weren't effrective on aircraft.
They were also to be used to destroy merchant shipping should the case
arise. I suspect they also may have tumbled out of their racks and
detonated when the Yamato rolled onto her beam ends and blew the ship
in half. FWIW Bismarck also fired her main battery at the Lancasters
coming in to sink her on that last mission - but to no avail. Wonder
what it was like when the Tallboys came down. Richter 9?

I think you meant Tirpitz there.

OOPs - mea culpa - senior moment - trying to think of more than one
thing at once. Hell, I used to be able to do that. Tirpitz it was.

This actually was fairly common. There are many motion pictures
showing USN ships banging away in order to create waterspouts in front
of low-level kamikaze attacks. I should think that was often done
against torpedo bombers, who had to fly at low level.

(To be sure, that's different from firing AT the aircraft.)

In the case mention (Tirpitz not Bismarck) the aircraft were flying
at 12000 ft so the guns must have been aimed at the aircraft
presumably more in hope than expectation of actually doing any good.

Also used by RN ships on (at least) the Malta convoys.

IIRC 3 of them hit the ship. Clean underwear time all round methinks.

There were 2 of these raids during which attacks were made.

On the first, which took place on 15 Sept 1940 the ship
was partly obscured by a smokescreen and only one bomb hit.

This hit about 50ft back from the bows and the bomb went
right through both deck and hull and exploded in the sea
bed below the ship. Much of the forward section of the hull
was flooded and a great deal of machnery damaged by shock.
The conclusion was reached that the ship was no longer fit for
sea and she was towed to Tromso to be used as a floating
fortress. This brought her within range of bombers from Scotland.

The second attack happened on 12th November and 2 hits were made
on the port side. The results were a massive explosion that blew
C turret right out of the ship which rolled over and sank very quickly.
