Hi h.sie,

very fine, thank you. Didn´t see that until now. But as far as i read, Metox was very helpful from 08/42 to 05/43, when U-Boat losses decreased significantly, whereas allied losses increased drastically. So i think 50% failure ratio from 12/43 to 03/43 is too much. Dezimeter H2S was used as airborne interception (AI) radar from 09/42, but this system was not used against U-boats. Anti submarine ASV Mk.III was in use since 03/43.

Please take a look:

Btw. Naxos RWR was used from 09/43 with "Finger" antenna covering 8-12cm wavelength. ASV Mk VII (3cm wavelength) and american SS (SU) radar (2.6cm) were used since 01/44. From 05/44 Naxos was used with "Mücke" antenna, covering 2-4cm wavelength.

So Naxos also failed from 01/44 to 04/44, and the early version had a principle dysfunction against allied radars, because of its horizontal polarisation (that was too modern, in this case).

So maybe we can assume a failure ratio of 75% from 09/43 to 12/43 an a 50% ratio from 01/44 to 04/44?

greetings.
