If the two Atomic Bombs on Japan still didn't force japan to surrender, Would there have been a Third bomb dropped on Japan ?

Groves expected to have another atomic bomb ready for use on August 19, with three more in September and a further three in October.

On August 10, he sent a memorandum to Marshall in which he wrote that "the next bomb ... should be ready for delivery on the first suitable weather after 17 or 18 August." On the same day, Marshall endorsed the memo with the comment, "It is not to be released over Japan without express authority from the President. Truman had secretly requested this on August 10. This modified the previous order that the target cities were to be attacked with atomic bombs "as made ready".

There was already discussion in the War Department about conserving the bombs then in production for Operation Downfall. "The problem now [August 13] is whether or not, assuming the Japanese do not capitulate, to continue dropping them every time one is made and shipped out there or whether to hold them ... and then pour them all on in a reasonably short time. Not all in one day, but over a short period. And that also takes into consideration the target that we are after. In other words, should we not concentrate on targets that will be of the greatest assistance to an invasion rather than industry, morale, psychology, and the like? Nearer the tactical use rather than other use

Two more Fat Man assemblies were readied, and scheduled to leave Kirtland Field for Tinian on August 11 and August 14, and Tibbets was ordered by LeMay to return to Albuquerque, New Mexico, to collect them.

At Los Alamos, technicians worked 24 hours straight to cast another plutonium core

Although cast, it still needed to be pressed and coated, which would take until August 16. Therefore, it could have been ready for use on August 19. However, unable to reach Marshall, Groves ordered on his own authority on August 13 that the core should not be shipped

Yes, there was a plan for the third atomic bomb to be dropped, somewhat in late September. Then we would have still continued carrying our carpetbombing of Japanese targets with incendiaries and explosives. However, Japan surrender made this argument moot.

The first two bombs were dropped August 6 and 9.

Major General Leslie R. Groves, Jr. expected to have another (the third) atomic bomb ready for use on August 19, with three more in September and a further three in October.

Yep. And a 4th, and a 5th, and a 6th, and so on. The targeting committee that picked the targets had several more lined up. And alternates. Actually Nagasaki was the alternate target for the second bomb.... Their target that day had been Kokura, but it was clouded in. They actually flew to Kokura first and had to divert to Nagasaki low on fuel. Kokura had a huge arsenal there. In fact in their report the targeting committee even refers to it as the Kokura Arsenal. The others are just listed by city name. If a 3rd bomb had been dropped it would've gone on Kokura. Assuming it wasn't clouded in again..... The targeting committee also specified in their report that if additional bombs had to be dropped they'd start picking smaller targets that were strictly military. Despite what many who don't know much about the conflict seem to think Hiroshima and Nagasaki were both military targets. They contained things like huge supply depots, Naval yards responsible for building ships for the Japanese Navy, Army group headquarters, etc. There were about 45,000 Japanese troops stationed in Hiroshima in the summer of 45. These military assets just also happened to be in and near cities. They intentionally wanted targets like that for the initial attacks because they wanted something really big in case they missed they'd still do some damage. The targeting committee explains this in their report, a copy of which is linked below.

And yes the bombs would've had to have been built and weren't ready yet. But they would've been able to have been built much quicker than the first three. Obviously. Since we tested 2 more in Bikini in July 46. They would've been ready even quicker under wartime urgency. Oh, and when those 2 at Bikini were detonated in July 46 we had EIGHT more in our arsenal......

No, of course not, The Japanese were trying to negotiate surrender even before the bombs were dropped.Not a single one of the Chiefs of Staff were in favor of using nuclear weapons. The bombs were dropped, not to speed Japanese surrender, but to test the new weapon against a civilian population, and of course to intimidate the Soviets.

Probably eventually, along with a 4th, 5th, and possibly more. I'm not sure if the US had enough fissile material left for a 3rd bomb right away, but it would have it within a few months. The US would likely use a multiple target strike to really drive home the message to the Japanese that the first two were not a fluke and that they really were staring at imminent annihilation.

Most likely a super bomb made in ethieopia

We just had two bombs we would have built a third bomb; in the meantime we would have carpet bombed all of Japan to give them something to think about.

There WAS no forth bomb. The first bomb was tested at Trinity. The second and third are all we had. It was a bluff of Truman's that worked.
