X6 dropped both charges whilst hard up against Tirpitz's port side roughly by B turret. X7 dropped one hard up alongside Tirpitz's port side in a similar position before moving about 180' aft (to where Place estimated X turret to be) and dropped its second charge under the ships keel.
Because the Germans had seen X6 (Cameron's boat) on the port side it was deemed probable that any explosive charge would have been laid on that side and Tirpitz's bows were hauled over to starboard with her anchors and cable-holders. The stern was secured by shore wires and it was not practical to move it. As a result the second charge, dropped by X7 did explode more or less underneath Tirpitz's keel.
I think that the explosive used in the charges was amatol too, but I'm not sure.
No bombers were lost to enemy action in these operations. I doubt the same would have been the case had Highball attacks been made, certainly not if Chastise is anything to go by.
I dont see 600lbs sinking the ship either. Even a 12,000 lb bomb going through the ship and exploding didnt sink the ship. It did keep the Tirpitz from going out to sea again, but it didnt sink the ship. After that, it finally took 2 more direct hits to send her down, but even the best of battleships could hardly survive a 12,000 lb bomb...
As I wrote the idea behind Highball was to achieve multible hits, enough torpedo hits sunk IJN Yamato and HB had almost as powerful charge than the warhead of the late war US Mark 14 torpedo had. Problem of course was to achieve required number of hits. Probably T would only have been damaged but the KM's problen would have been, that there were no docks large enough in Norway, so if the hull and torpedo defences would have been ruptured the repairs would have been difficult. The X-craft charges were not laid directly under T's hull, so they lost much of the effect of the air bubble and IIRC the charges were Amatol, which is different HE than Torpex. It was decades ago when I handled military explosives so I cannot say how much more powerful than Amatol Torpex is, but it is clearly more powerful because TNT is powerful than Amatol.

It likely came from AVRO chief aerodynamicist (Sir) George Edwards who was a keen cricket player.
Edwards worked for Vickers, not Avro.

German flak units in Norway
This site gives the Norwegian flak defences as the 83 Flak regiment in attendance (or brigade, to use the terminology the norwegian source uses)
The unit had the following equipment and manpower allocations
158 x 88mm, 73 x 37mm, 332 x 200mm, 152 officers, 4893 EM. These are just the land defences. The shipboard defences were not particualalry heavy, but did include the 8x 15 in guns now with sanshiki style ammunition, the 12x 150mm guns now with limited DP capability, 16 x 105mm, over 30 x 37mm guns and nearly 60 x 20mm guns. Chief defences were smoke generators that made attacks particualarly difficult,placed around the fjord, and designed to fill the valley with thick smoke. .
These defences were heavier than for any other point target that im aware of. i dont know the flak defences of Katfjord,but the flak formation was transferred from that area to the tromso anchorage at about the same time as Tirpitz's move. One can assume it was similar to the tromso defences
The natural benefits of Tirpitzs Katfjord anchorage were appraised by Admiral Fraser and his staff, prior to the April attacks. They advised Cunningham that the natural benefits conferred by the anchorage made it virtually impossible for any success to be expected from air attack. They were remarkably accurate assessments as it turns out. They were so pessimistic about success, that initially Fraser refused to take on the mission. Eventually ABC pursuaded him to try. I think it significant that despite the lack of success, such results did not adversely affect frasers career advanacement. Evidently his bosses must have known just how difficult the operations were. They did not punish him or hold him back because of failure, and his reluctance to take on the job in the first place speaks volumes about just howhard a job it was.
I don't know what you were trying to link to but you have provided the order of battle for all Luftwaffe FLAK regiments in Norway during the Invasion, Fall Gelb. Not the defences of the Tirpitz at Kåfjord.
The one of the photographs I have provided shows the Tirpitz actually under attack during operation Tungsten. I can not see any shore AAA defences of significance.
.Harbour defence was the responsibility for the most part of the German Navy who had troops to defend harbours, man shore batteries artillery and FLAK. A typical heavy FLAK battery consisted of 6 x 8.8cm FLAK 37 guns and 2 x quad 20mm (mainly for self defence.). They were of course useful to fend of tanks, PT boats, to provide counter artillery fire. FLAK batteries even sank a number of RN destroyers. It certainly would have been wise to have several around the tirpitz, but it doesn't seem to have happened. I doubt there was even one. Only the shore on the bottom provides any possibility
Indeed, and I've seen him described as Britain's greatest aeronautical engineer. I always liked Edward's notion that the Spitfire was not Mitchell's epitaph but that the B.12/36, which Edwards considered 'an incredible design' should have been.
In March 1945 Shenstone, so influential in the design of the Spitfire, was offered the princely sum of £2,000 pa (double his current Air Ministry salary) by Hew Kilner (Managing Director of Vickers) to work under Pierson at Vickers-Armstrongs in Weybridge, a job that was an obvious step in him becoming Vickers chief designer. Shenstone declined the offer, preferring to stay in Canada, and the job went to Edwards. Shenstone was magnanimous, writing.
"I did not accept the offer. George Edwards got the job and he did it better than I could have done it, as I learned later when I did return to England."
It makes you wonder what a VC 10 designed by the man who designed the Spitfire wing might have looked like
Getting a bit off topic here...never mind.
