BRP Ramon Alcaraz (PF-16) was fitted with this weapon last November while BRP Gregorio Del Pilar (PF-15) will be fitted with the Mark 38 25mm "Bushmaster" during her next dry-docking period which is scheduled between February and June this year.
This was confirmed by Philippine Fleet public affairs officer Lt. Liezel Vidallon.
The Mark 38 25mm "Bushmaster" auto-cannon will improve the ship's surface warfare capability.
Surface warfare refers to the capability to detect, engage, and if necessary, sink naval ships or unidentified vessels that may intrude in the country's vast territorial waters.
The secondary 25mm weapons will complement the 76mm Oto Melara main gun and allow the frigates to handle targets coming fast and that are too close for the ship's primary weapon to engage.
The weapon, commissioned by the United States Navy following the terrorist attack on the USS Cole in 2000, was designed to counter high-speed maneuvering surface targets. It will be installed in almost all US surface ships by 2015.
The remotely controlled chain gun system can fire as many as 180 25m rounds per minute at targets as far as two kilometers.
