USS Defiance (PGM-95/PG-95) was a gunboat in the United States Navy and later transferred to Turkey.

This system allowed for them to cruise at economical oil use levels, by only using the diesel engines, but also sail quickly when needed, by using the gas turbine.

[2][3] Her identifying symbol was of a clenched fist holding three lightning bolts, with the motto "With Knowledge and Confidence to Defy".

[1] Defiance was decommissioned on 11 June 1973 in Izmir, Turkey, and, immediately after, she was transferred to the Turkish Navy, renamed as Yildirim (P-338).

She was destroyed by an explosion & ensuing fire on 11 April 1985 off the coast of the Greek island of Lesbos in the Aegean Sea.
