The SURCOUF was never at the Portland Navy Yard, 'cause there's no such place. Now, we have a Naval Shipyard in Portsmouth, New Hampshire, that the SURCOUF was outfitted with
the 10cm SJ surface searcg radar, as well as the 1,5m SA air search radar. This was accomplished in September, 1941.
It has been reported that SURCOUF took on torpedoes during this
shipyard availability. I want to point out the fact that U.S. submarine torpedoes (MK 10 and MK 14) would never work in the
torpedo tubes aboard SURCOUF.
She had two two rotating torpedo mounts. One had four 21.7" tubes, the second had four 15.7" tubes. The U.S. Navy never had a 15.7" torpedo, and their 21" torpedoes would never work in the
SURCOUF'S 21.7" torrpedo tubes. The tripping latch and torpedo
stop bolt mechanisms would never line up properly.
The French submarine torpedoes could not reliably depend on gyroscopeic controls for presetting the angular paths of their trsck. Instead, they employed quadruple traversing mounts which were mechanically turned aout in various directions before ffiring.
Can you tell me what the "spares" were that SURCOUF took on at
Portsmouth, NH?
