   Aerial mine laying in the Baltic and in Danish Waters was a major operational problem for the Kriegsmarine throughout the war.  Many of the Kriegsmarine radarstations on the Baltic Coast and in Denmark were established with the specific purpose of detecting minelaying aircraft.  If the aircraft was tracked accurately, when the mine was dropped, it was actually possible to see two echoes and thus establish the drop position with a reasonable accuracy.  This of course greatly facilitated subsequent mine sweeping.  In order to improve the low level coverage a number of Wachschiffe were equipped with FuMB equipment, and a number of Vorpost Boote were equipped with FuMO 3 or FuMO 62 and FuMB equipment.  The list below represents my present state of knowledge of these ships.

(1).  There is some confusion concerning V 1601.  At one stage HDMS Lindormen carried this tactical name.  HDMS Lindormen was built in 1939 for the RDN, scuttled by her own crew 29 AUG 1943, salvaged by the KM and named V 1401 later V 1601.  V 1601 Newhaven was the command ship of 16.Vp.Fl.  At some time it must have been withdrawn from active service in order to be refitted as Nachtjagdleitschiff  Skagerak.  The "Togo" was intended to fill this role, but she left Danish waters in FEB 1944 due to developments in the Eastern Baltic.  It seems reasonable to assume, that the decision to modify Newhaven and withdraw her from active duty for the refit was taken at this time.  This could explain the transfer of Lindormen from 14 .Vp.Fl. to 16.Vp.Fl.  In Jahresbericht 1944 from 8.Sich.Div. it noted that, at the end of the year V 1601 is being fitted with a radar, this V 1601 must be Lindormen.

 
         
  (2)  Thanks to Paul Sedal the circumstances concerning the sinking of V 1605 has been discovered.  On 15 OCT 1944 the vessel was escorting the tanker "Inger Johanne" off Lillesand (Norway), when the convoy was attacked by 30 Mosquitos.  Both vessels were sunk.  It is interesting that these vessels apparently were used as radar-pickets on escort duties.

  Not unexpectedly the sources are not crystal clear and some are self-contradictionary.  When a vessel was transferred from one Vp.Fl. to another it's PTNO changed.  So several vessel could over time carry the same number.  This makes proper identification a bit messy.  I have chosen to use the number/name combination depicted on the small drawings of Gröner, since the text at times is somewhat ambiguous.
