(b) reload a torpedo from the internal storage?
2. For G 7e torpedoes, I understand they needed on-board maintenance about every five days:
(a) on average, how long did it take to complete this maintenance per torpedo?
(b) did this maintenance include pre-warming?
(c) if not, on average how often did the G 7e have to be pre-warmed and how long did it take to do so?
3. For G 7a torpedoes, am I correct that they did not require regular on-board maintenance or pre-heating?
Thank you in advance!  |
i can shed some light on questions 1a and 1b, i'll have to check my books on the others
1a)
with dock-side cranes and no interruptions: about 45 minutes per eel.
underway (reloading from external reserves), with calm seas and the boat-specific crane: at least 1.5 hours per eel.
1b)
a good crew could reload all four tubes within 20 - 25 minutes. so, about 5 minutes per torpedo. Günther Prien during his Scapa Flow engagement fired 2 salvos (3 torpedoes each time) from his bow tubes at 00:58 AM and 01:13 AM, respectively.
hope that helps
