ESSEN, Germany, Nov 19 (Reuters) - German state-lender

KfW is currently carrying out a main review of whether

to take a stake in Thyssenkrupp's warship division, the

conglomerate's CEO Miguel Lopez said on Tuesday.

Thyssenkrupp is targeting a spin-off of the division, which

builds submarines and frigates, after possible suitor Carlyle

stepped back last month, with a potential government

participation via KfW seen as one of the options.
