Hi gents,
Here are another few shots of the G7e torpedo -
U 47 fired 7 torpedoes, 4 of which hit the Royal Oak. The curator of the Stromness Museum could not advise which torpedo the artifact came from. But he kindly allowed me to take photos. What struck me was the weight of the piece - far heavier than it looks. There are four prop blades (two on each section); the two sections counter-rotate to alleviate torque.
Interestingly, one of the three which missed floated to the surface of Scapa Flow in the comparatively recent past. If my memory serves me well, it was detonated by Royal Navy personnel.
In the course of researching U 47 and her patrol history, I estimated that U 47 was responsible for a death toll in the region of 1,932 sailors. This appalling figure would have been even greater if the German torpedoes had functioned more reliably. Of the 87 torpedoes fired in the first 9 patrols, 56 missed or failed (I don't have the shooting reports for the 10th patrol as the boat was lost on this patrol). U 47 fired upon several troopships off Norway. Thank goodness the torpedoes did not strike these troopships as the loss of life would have been terrible.
It was quite something to handle part of one of the torpedoes fired during the raid. But my enthusiasm was tempered very much by the thought of the destruction wrought by the torpedoes that evening.
Below are photos of another piece of history. This shows the message received by Scapa Flow on 3 Sep 39 upon the outbreak of war - "Commence hostilities with Germany".
This document resides at another museum, this time on the Orkney island of Hoy.
In the forecourt of the Hoy museum are several large artifacts from the German High Seas Fleet. The fleet was scuttled in Scapa Flow in 1919. See -

A number of the warships are still in Scapa Flow.
