In 1942, it was decided that the hull of the half-finished heavy cruiser
KMS Seydlitz should be converted to an aircraft carrier, in order
to provide local air cover for German capital ships. In Bremen, work
began to dismantle the superstructure of the would-be cruiser. Probably
the armament was already removed to the Atlantic Wall or the Norwegian
coast. Some time around November or December 1942, all remaining
superstructure was removed and Seydlitz left Bremen for
K�nigsberg.
On New Year's Eve, 1942, the Battle of the Barents Sea took place, in
which a superior German naval force was turned away by British light
cruisers and destroyers. Hitler was furious and ordered all capital ships
decommissioned and all works in progress abandoned. In the few months
Seydlitz spent at K�nigsberg, not much work towards becoming
an aircraft carrier could have been done; only some basic flight deck
support construction had begun.
No more work were ever done on Seydlitz. She remained in the
Schichau Yards in K�nigsberg until the Russians arrived in April 1945,
when she was scuttled to prevent capture. She was renamed Poltava
by the Russians and plans were made to rebuild her. They were canceled
and the hull was scrapped around 1950-51.
