B-Dienst Report: The new Allied radiolocation system ASV 271-Mark-III (9.7cm Range) was used over the Bay of Biscay by bombers of the RAF No. 172 Squadron. This new radar system can locate Uboats at a distance of 12nm (22.22km).
To U 191: Fiehn: Proceed to AE 2233 at high cruising speed. From there obtain information on the ice boundary north of Iceland and in the Denmark Straits. Report on this at the latest by 26.3 south of 61° N. Remain unobserved as far as possible and you are forbidden to attack any ships except troop transports and cruisers and above.

Cmdr.: I appears as though, that at least some of the attacking aircraft are also equipped with the new radar system (mainly Sunderlands), as it seems that our installed FuMB system is unable to detect this new radar frequency. Detection by Magic Eye has only been done once thus far.
The boat that we left in convoy with from Kiel and Kristiansand, received special orders. We wish her best of luck!
