(Historical data)
The Teniente Vasquez class is expected to be an effective light combatant capable of capital ship escort as well as detached duties such as minelaying. There is a significant margin for future growth, such as sensors; while radar is not so plentiful that Peru can immediately install sets on all warships, its eventual installation seems inevitable.
In a change from previous design practice, a light twin 120mm dual-purpose gun is being introduced instead of the 150mm LA guns employed on Valdes and Independencia classes. It is thought that anti-surface action will benefit from the smaller but more easily handled shells, to say nothing of the gains in anti-aircraft firepower.
