G' Day all,
Back in town. The subject of German naval radar in WWII is a thorny one with a fair amount of disagreement between sources on which types and when installed on various ships. Probably because radar was not a major contributor to German naval tactics. In the early days of WWII, the Kriegsmarine fielded some early type radars that were as good as anyone else's - as you would expect from the always technologically savvy Germans. However, as Healy36 and others have noted, my research concurs that Kriegsmarine leadership became quite concerned/obsessed that transmitting radars could be easily detected and located. While it might seem bizarre today, German commanders were encouraged to keep their radars off to remain "hidden." This resulted in a number of painful surprises in the battles in the Arctic and elsewhere. Further, it led the Kriegsmarine to focus on radar detectors instead and not prioritize further development of naval search and fire control radars. Instead, the Germans put their energies into developing a series of radar detectors for naval use. The end result is German naval radars lagged behind evolving Allied radars in capability and reliability and, combined with reluctance to use operationally, meant that they didn't have a major impact in combat or even get outfitted on smaller ships until surprisingly late. My sense is that's why there is not a lot of ink spilled about German naval radars in sources publicly available. Books and articles written about various classes usually provide some data about radar outfits, but it is usually brief - and often conflicts with other sources. That is particularly an issue for DDs and smaller warships.
The difference between the radar listings in the standard Ship Logs and the Deluxe Ship Cards results from different approaches used to develop them. I prepared the standard Kriegsmarine Ship Logs for use throughout the war years 1939 - 1945. When a ship in a scenario doesn't yet have radar or it is not operational, the Log is easily adjusted by simply drawing a line through the notations on it. Or, add a notation if needed for a late war scenario. The Deluxe Ship Cards, on the other hand, were developed to provide multiple Cards for many ships to reflect changes at different points in time. These are indicated by the small text line in the light yellow margin immediately beneath the Card. For an engagement, just select the Card for the time period being simulated. A more "Deluxe" approach to reflect differences in armament, AA and radar for a given ship at point in time. Thus, a given Deluxe Ship Card may differ from the standard Ship Log.
In both cases, you are left with the potential for disagreements between sources. We used the best sources available back when we prepared the ship data. More sources have been published since then, which has added to the issue. Until someone produces a definitive work on German naval radars, you can use the capabilities we found or adjust them for a given scenario if you find a new source you prefer.
