One thing about the torpedos: sure they are the same speed but you have to remember the torpedos motors have a finite range and they have to actually catch up to a moving target even with a deflection shot as soon as the torp is spotted the Queen can maneuver and speed up to outrun the torp.

On May 25, 1944 U-853 spotted the Queen Mary, which was loaded with American troops and supplies. The U-boat submerged to attack, but was outrun by the much larger and faster ship.[5] As she surfaced in the Queen Mary's wake U-853 was attacked by Fairey Swordfish aircraft from merchant aircraft carriers MV Ancylus and MV Empire MacKendrick.[6] The U-boat took no significant damage and returned fire, hitting all three aircraft. The planes were able to return to their carrier, but after recovery one was deemed a total loss and jettisoned.

TO the German who could sink the grand ocean liner RMS Queen Mary, Nazi leader Adolf Hitler had promised $250,000.
On June 12, 1943, the crew of a German U-boat was preparing to collect.
They found themselves in the unique position of being dead ahead of the fast-moving ocean liner, which carried more than 6000 troops across the Atlantic from Britain to America during World War II.
Stafford Heights local Cyril Burcher was flying out in a Liberator bomber to find the Queen Mary and escort her across the Atlantic when he chanced upon the U-Boat through a cloud clearing.
Unaware of the Queen Mary's presence, Mr Burcher attempted to test a new homing torpedo on the U-boat, but first had to get the submarine to submerge.
After a brief exchange of fire, Mr Burcher flew through a rain squall to give the impression he was giving up, in the hope that the sub would submerge on its own.
Cyril Burcher went from being an accountant to saviour of the Queen Mary.
"So I flew through this cloud, and here was the Queen Mary right below us, and heading straight for the U-boat," he recalls.
"That was why it didn't dive. It would have had radar contact with (the ship) and knew it was a very large boat and probably the Queen Mary."
As radio silence couldn't be broken, Mr Burcher signalled in morse code using an Aldis Lamp: 'U-boat on surface, six miles dead ahead'.
"And the Queen Mary immediately did a 90-degree starboard turn at about 36 knots. It was a beautiful sight to see.
"So when we knew the Queen Mary was safe, we went back to see if we could find the submarine, but it had dived, of course."
Five years later, the captain of the Queen Mary, Sir James Bisset, met Mr Burcher and personally congratulated him for saving the lives of more than 1500 troops that day.

In 1942, at the height of World War II, the Curacoa (British light cruiser of 4,290 tons) was in a convoy escorting the Queen Mary when a decision was made onboard to chase a u-boat that had apparently been sighted nearby. Unfortunately, for all aboard the Curacoa, it crossed the path of the Queen Mary in its pursuit of the u-boat and was promptly cut in two in a resulting collision, and sunk. The Queen Mary did not attempt to stop and rescue survivors from the Curacoa. She was too busy trying to survive a potential u-boat attack by engaging in zigzag avoiding manoeuvres at a speed of twenty eight and a half knots . The 'Queen' was badly damaged, her bow plates folded back at least forty feet into the ship. A total of 338 men aboard the Curacao died as a result of this tragedy (25 officers and 313 ratings) There were 26 survivors. The incident occurred some 20 miles off the coast of Donegal, Ireland. The Curacoa lies northwest of Bloody Foreland, Donegal. The two parts of the ship lie on the seafloor about 500 metres apart from each other.
