The corvettes are armed with one 57-millimetre (2.2 in) Mk3 naval gun on the fore deck to engage air and surface targets.

The 57 mm gun is capable of firing 220 rounds per minute to a distance of 17 kilometres (9.2 nmi; 11 mi).

The fire was brought under control with the aid of the Petróleos Mexicanos (PEMEX) tugboat Avila Karisma and the Mexican Navy vessels ARM Sierra, Durango and Sonora while the crew were evacuated to Mexican naval facilities in Ciudad del Carmén, Campeche.
