Sooooo iirc it was early to mid 44 when the Allies gained air supremacy which meant U-Boats could not stay surfaced long enough to charge their batteries, not to mention the long process of loading torpedoes. For a more precise answer I'd suggest having a look over at https://uboat.net/

No problem and iirc the TypeII, XXIII and XXI were the only boats designed not to carry externals.

the question intrigued me so I did some serious pervitin induced homework over breakfast. Nothing is particularly extant on torpedo storage other than it was dangerous, time consuming and only suited to calm waters; which the winter Atlantic was decidedly not! they key to the myriad aspects of the issue was the closing of the Mid-atlantic Gap. Only low maintenance G7a eels could be carried externally as every other type (G7e's ZaunK's, Foxers ) required high battery maintenance-new fact for me! I'll be more authentic in SH-V!! Also, torpedos in the external containers were susceptible to depth-charge attacks and were often damaged. No astute commander following such an attack would risk the amount of time 'hazarding his vessel' against the futility of a defunct eel lugged inside the pressure hull. For certain, the type XI's wouldn't have wasted the always precious fuel-consuming weight on its capacity for 10 eels stored topside As mid ocean Milch-cow resupply subs got scarcer

I also seem to recall that pressures at depth messed with them too.

up on that too in the course of composing my post; but that had been solved-scandal notwithstanding- prior to the period involved with your question or Jimbuna's time frame. Essentially, I'm interested in finding any actual 'eel' manifest of a June '43 non-ace skippered U-boat outbound for the Gap....'twould shed much insight on the question.

I guess it's gotta be the year of 1943, maybe after the Black May.

A LITTLE REQUIRED READING: https://digitalcommons.georgiasouthern.edu/cgi/viewcontent.cgi?article=1599&context=etd pg. 65! DRUMBEATER HARDIGAN ONLY CARRIED 15 EELS ON HIS TYPE IXB U-123 ON EACH OF TWO PATROLS (7 & 8)TO THE AMERICAN COAST. pg. 147-148: With torpedoes, Hardigan bagged eight ships on each patrol, and three with deck gun fire: a poor performance of an average of two + eels per victim. It gets you a knights cross but does not win wars. It is noteworthy that for whatever reason, only 15 were carried on the 6, 000+ mile voyages
23 December 1941 – 9 February 1942 (Previous to black May 1943) out of a possible 22 maximum; (the IXD could carry 24.) Type IXs had six torpedo tubes; four at the bow and two at the stern. They carried six reloads internally and had five external torpedo containers (three at the stern and two at the bow) which stored ten additional torpedoes. The total of 22 torpedoes allowed U-boat commanders to follow a convoy and strike night after night. KALEUN HARDIGAN WAS 16 STORED EELS SHORT OVER TWO PATROLS: AT HIS 2 EEL PER SHIP 'KILL' RATE, EIGHT MORE ALLIED SHIPS WERE NOT SUNK. REINHARD HARDIGAN DIED AT AGE 105....OBVIOUSLY HE MADE FEW MISTAKES, IE NOT CARRYING A LOT OF TOP SPARES G7a'S IN OPERATION DRUMBEATER.....
