The explosion sunk another cargo ship and damaged many others.

That is the largest conventional explosion I've seen.

Looks almost nuclear. Major visible shock/pressure wave!

Looks like part of the deck structure flying upper right skyward in the first few instance.

The first person accounts are something. Talk about pressure if you are a gunner. No cool missile or tech guided system to take the plane out.

A Liberty ship, full of ammunition and a large bomb perfectly placed.
Kamikaze's killed a lot of people in the last year of the war. Probably the most effective weapon they had.
People today don't realize that the Islamic terrorists have nothing on the Japanese when they thought the Emperor was a god.

It was actually a Liberty ship in the merchant marine, the SS John Burke, rather than the USS John Burke. It was carrying munitions, the reason for the size of the explosion. Everything seen is a secondary.

quote:
In early December 1944, John Burke left Seattle, Washington, for the island of Guam. Once she arrived there, ammunition was loaded onto the ship for the American invasion of the island of Mindoro in the Philippines. John Burke left Guam with a 100-ship convoy and arrived off the coast of Leyte in the Philippines on the night of 27 December 1944.

Japanese aircraft based in the Philippines spotted the convoy’s arrival shortly after dawn on 28 December 1944. Six Japanese kamikaze aircraft were launched from Cebu Island in the Philippines and directed towards the convoy.

At approximately 1000 hours, the six Japanese planes arrived over the convoy. Through holes in the clouds, the Japanese pilots sighted the large American convoy and dove in for the attack. One of the pilots chose John Burke as his target and made his final suicide run into the ship. Despite heavy anti-aircraft fire from the convoy, the kamikaze crashed into John Burke, plowing deep into her hull.

A brief flash of fire emanated from John Burke and was visible to most of the ships in the convoy. For several seconds, only smoke could be seen billowing from the stricken ship. After a few more seconds, a huge pillar of fire shot out from John Burke’s cargo hold, followed by an immense cloud of white smoke. Within seconds, all eyes in the convoy were drawn to John Burke and then an enormous fireball erupted as her entire cargo of munitions detonated, instantly destroying the ship and vaporizing the crew of 68 officers and men. For several seconds, nothing was visible under an enormous mushroom cloud of smoke, fire, and explosions.

Several ships that were steaming near John Burke were damaged by the force of the blast and by flying pieces of the disintegrating cargo ship. A massive shock wave rocked the entire convoy so hard that several ships reported that they had been torpedoed. A US Army transport just aft of John Burke was severely damaged by the blast and sank before it could be identified. As the smoke gradually cleared, nearby ships steamed into the area searching for any survivors from John Burke. They didn’t find a trace of either the ship or her men.

The Japanese attack that morning was just the beginning of a series of attacks on this convoy, which cost several more ships and hundreds of lives. The cargo ship S.S. William Sharon was also sunk by the same group of planes that destroyed John Burke. But despite almost constant air attacks, the convoy reached its destination of Mindoro on 30 December and was able to supply the American troops fighting on that island with badly needed food, fuel, and other vital equipment, not to mention additional munitions to carry on the fight.

The loss of John Burke and her entire crew showed how unbelievably dangerous it was to transport munitions to a war zone during World War II. But if armies are to win wars on land, they need a steady stream of munitions, usually supplied by ships. Incredibly brave men sailed on those ships, knowing that at any moment their lives could suddenly end in one, blinding, flash. For the people on board John Burke, that’s exactly what happened.

IIRC the Liberty Ships were designed to carry around 10,000 long tons but was not uncommon to carry more. So the SS Burke had a minimum of 10,000 long tons of munitions. Normally it would not all be HE but a mix of HE, Smoke (WP and chemical), propellant and other stuff necessary to supply the artillery. Munition's amount of HE is approximately a third of it's total weight. As shipping tonnage is measured by cube not weight it is safe to say that she probably had close to 5,000 to 7,000 tons of explosives on board. In a mass explosions such as this the propellant would explode adding to the mass of detonation. A good guess would put the ship explosion at around 5-7 KT. The bomb at Hiroshima, Little Boy was around 15-17 KT depending on sources so the SS Burke blowing up was about half of the detonation force of the first A-Bomb.
