Light
Cruisers
None of the German light cruisers which took
part in the assault on Norway had radar. Two of the three 'K' class
cruisers were lost in this operation, so the only remaining modern light
cruisers were Köln and Nürnberg. Leipzig's
fighting potential having been so reduced by a torpedo hit, that she served
as a cadet training ship for the rest of the war as did the obsolete Emden.
While Köln and Nürnberg
served with the Norwegian stand-by-force, they were fitted with a FuMO
21, with 2m x 4m mattress antennas in place of the forward rangefinder.
In the summer of 1944 Nürnberg
received a large FuMO 25 frame on one of the yardarms of the armored tower,
above that, on a smaller yardarm was a rotating frame carrying two Palau
dipoles. However, one photograph of Nürnberg indicates
that earlier she had a FuMO 22 with a 2m x 4m mattress antenna, place on
her prominent forward yardarm.
The flanks of the armored spotting top
were surrounded by some five fixed Sumatra dipoles which remained
in place when the Palau frame was installed later, only one Sumatra,
bearing in the forward direction, being removed.
Leipzig was similarly equipped
after her recommissioning in August 1943, only the form of the large outrigger
and the position of the yardarm supporting the Palau frame being
different.
As Köln was active until the
end of the war, it may be assumed that she was modified to the same standards,
but there are no photographs showing this.
As the only remaining active major German
surface vessel in the latter stages of the war, Nürnberg was
fitted with a fully trainable FuMO 63 Hohentwiel-K on the top of
her mainmast, which had to be strengthened with tripod legs. In the
last phase of the war Emden received a FuMO 25 in similar configuration.

Köln's forward
rangefinder replaced by FuMO 21 antenna (as fitted in destroyers) in the
summer of 1941 or 1942; carried until 30 April 1945. Modification,
similar to those in the FuMO 25 of Leipzig, is possible but uncertain. |

Other
major units
During extensive refits in the last weeks
of the war, the two old pre-dreadnought battleships Schleswig and
Schleswig-Holstein
were equipped with radar similar to that in Nürnberg and Leipzig:
A FuMO 25 with a large 2m x 6m mattress on an outrigger and a smaller training
Palau
frame above.
Most larger auxiliaries, such as tenders
of the Wilhelm Bauer class, the Gustav Nachtigal class and
the Carl Peters received a standard FuMO 21.
The floating AA batteries Udine,
Ariadne,
Niobe
and Arcona, some built on the hulks of First World War cruisers
(e.g. the Gazelle class), were fitted with the AA fire control radars FuMO
212 or 213 Würzburg-C or -D. |
