The IPMS/USA 50th. Anniversary Award was presented to Mr. Santiago Ezcurra for his 1/350 scale model of the submarine ARA (S-11) "SANTA FE" at their national contest in Mar del Plata, Argentina, on 17-18 August 2013.

The submarine ARA (S-11) "Santa Fe" was in active service in the Argentine Navy in 1964. This was a Balao-class unit (former USS MACABI SS-375), given by the U.S., with her sail modified in Argentina to improve hydrodynamics and to make it similar to the Guppy I standard, applied before to the ARA (S-12)" Santiago del Estero" . The kit used was the "1941 Gato class submarine" from AFV Club, with a new scratch built sail.
