Project history: Strongly armed purpose-built escorts, originally planned as improved variant of
Eolo class minelayers, however finally as the prototype British Black
Swan class sloops were chosen. First four
Pizarro class gunboats were ordered by the decree from 2.9.1941, second four
by the decree from 25.9.1943. They were repeatedly redesigned, building was conducted under project 149B, all armament should be presented
by German samples, and main artillery to
consist from 3 twin 105mm/60 SKC/33 guns in stabilized DP mounts.
Machinery was installed en echelon, similar to used on
Jupiter and Eolo classes, but with
steam temperature increased to 355°C.
Because of fall of Nazi Germany delivery of artillery and part of equipment has not been effected, that has compelled to
complete ships already after the Second World War without
sonars and with improvised armament.
Modernizations: 1952-1954, all: were armed with 3 x 2 - 120/50 NG48, 4 x 2 - 37/83 SK C/30, 6 x 1 - 20/65 C/38, 4 DCT, 1 DCR, 30 mines
1960, Vicente Yáñez Pinzón, Legazpi: were modernized as ASW frigates, armament was consisted of 2 x 1 - 127/38 Mk 30, 4 x 1 - 40/70 SP48, 2 - 324 TR (side, 6), 2 x 24 - 178 Hedgehog ASRL, 8 DCT, 2 DCR; sensors included MLA-1B, SPS-5B, Decca TM626, Mk 29 radars, QHBa sonar
Naval service: In 1958 all were re-rated as frigates. Vicente Yáñez Pinzón was re-rated as patrol in 1974.
