ARV Mariscal Sucre (F-21)

Venezuela ordered six Lupo-class frigates from CNR in 1975 as a replacement for older warships. These units were commissioned between 1980 and 1982. In general terms, their appearance and equipment is similar to those built for Peru, except for some differences in electronics and missiles. The first two ships, ARV Mariscal Sucre (F-21) and ARV Almirante Brión (F-22) were upgraded by Ingalls Shipbuilding over a four years period (1998–2002). The other ships in Venezuelan service were expected to undergo an austere version of this upgrade, but three ships were eventually taken out of service.

Mariscal Sucre was laid down on 19 November 1976 and launched on 28 September 1978 by Cantieri Riuniti dell'Adriatico at Riva Trigoso. She was commissioned on 10 May 1980.

Over the years she has participated in multiple important naval exercises and has been the flagship of the multinational UNITAS exercise.

The unit was equipped with MTU 20V 1163 diesel engines, the new Elta EL / M-2238 Star 3D surveillance and air search radar, the ESM / ECM Elisra NS 9003/9005 system and of the Elbit ENTCS 2000 system for shooting control. The SCLAR launchers have been replaced by 130mm Mk 137 launchers, as well as the sonar which in the new configuration is the Northrop Grumman SQS-53C hull mounted. The ships are equipped with the Sperry marine MK 39 navigation system and the SHINCOM 2100 integrated communication system from DRS Technologies.
