Esmeraldas-class

The development of this corvette class for the Ecuadorian Navy began with an order placed in the late 1970s. The vessels were designed as an evolution of missile corvettes previously produced for the Libyan fleet, featuring upgraded propulsion systems and revised armament configurations. Based on a standard export design utilized for various international navies, the program resulted in the completion of six hulls, which began entering active service during the early 1980s.

These platforms are configured for multi-role maritime engagement, utilizing a four-shaft diesel propulsion system to achieve high-speed transit. The primary offensive capability is centered on anti-ship missile launchers positioned amidships, complemented by a surface-to-air missile system located aft of the superstructure. Naval gunfire support and point defense are provided by a main gun assembly on the foredeck and a secondary twin anti-aircraft mount. For sub-surface engagements, the vessels are equipped with torpedo launchers and a hull-mounted sonar system. While the ships lack a permanent hangar, the inclusion of a helipad allows for the operation of light utility helicopters. Surveillance and targeting are managed through a suite of air and surface search radars alongside dedicated fire control systems.

Since the early 1980s, the fleet has remained in continuous operation with the Ecuadorian Navy, serving in roles that include maritime training. The operational history of the class includes a significant fire-related damage incident involving one vessel in 1985, which required a two-year repair period. Resource management led to the removal of torpedo systems from two units in the early 1990s to equip newly acquired frigates. Although planned mid-life upgrades were initially deferred due to financial constraints, several units underwent life-extension refits between 2017 and 2018. These modernizations integrated a locally developed combat management system to maintain the operational viability of the hulls.
