Technical details:

The ships are characterized by a low freeboard, 76mm Oto-Melara gun turret forward, large funnel amidships and a crane and Rigid Hull Inflatable Boat (RHIB) aft.

The Oto Melara 76mm Compact DP can send shells up to a range of 10 nautical miles and can be used against ships, aircraft or ground targets.  It is remotely controlled from the Combat Information Center and has no crew within the gun itself.  The gun can fire 80 rounds in 60 seconds without reloading it’s magazine.  This ship has space for up to 450 rounds.

In addition to the 76mm gun, these ships also carry two machine guns (two 7.62mm) and one 20mm Oerlikon.

They are diesel powered and have two APE-Crossley SEMT-Pielstick diesels (14,188 bhp combined) driving two three bladed props. There is also a drop down loiter engine with a shrouded prop of 181 bhp used to keep station and save fuel.  The main engines can propel the 664 ton (712 tons full load) ship at over 28 knots. 25 knots sustained.  Range is 2,500 nautical miles at 17 knots.

The ships were specifically designed for Asian service.  As such, they have air-conditioned crew spaces and have been designed to stay at sea during typhoons.  However, the ships were modified soon after entering Royal Navy service with deeper bilge keels to alleviate a propensity to roll during moderate and heavy seas. 

Service History

The most modern combatants in the Philippine Navy.  The three ships of this class originally formed the Hongkong Squadron of the Royal Navy.  The ships were built by Hall Russell in the UK and were commissioned into Royal Navy service in 1983 and 1984.  They were built specifically for service in Hongkong.  They were sold to the Philippines and turned over to the Navy on August 1st 1997 when Hongkong was ceded back to China. 

Current Status

Phase I of a III stage modernization program for the three ships has been completed by the beginning of 2006. QinetiQ was the program manager for the Philippine Navy. 

Phase I involved armament and electronics upgrades, Phase II is the propulsion upgrade, Phase III is through life support for the program.  Phase I was approved in Nov 2003 and was officially completed in 2006. Phase II and III are currently under negotiation. 

Phase I commenced with the first ship is going into drydock at the Keppel SY in Batangas.  The first ship, PS35 BRP Emilio Jacinto entered drydock in November 2004 and will complete Phase I modernization by April 2005.  The second ship is slated to enter the Phase I program on February 2005 and finish in October 2005.  The third and last ship entered the program in March 2005 and was completed by November 2005.

The Phase I modernization involved:

1. Installation of a new Electro-Optical Tracking/Fire Control System manufactured by Radamec (Radamec 1500) and its integration with existing main gun and new 25mm gun.  The new fire control system is meant to provide fire control solutions for both guns and provide a day/night/all weather engagement capability.   The Radamec 1500 System was also selected by the Irish Naval Service to upgrade their ex-Royal Navy Peacocks class patrol ships.  It also equips the new Irish OPS LE Roisin.

2.  Installation of a new 25mm gun mount manufactured by MSI Defense Systems and its integration with the new fire control system.

3. Complete refurbishment of 76mm gun to bring it to full capability. 

4.  Installation and integration of new navigation systems – new Gyro Compass manufactured by Raytheon, Radar by Sperry Marine (Sperry Marine Bridge Master E Series radar), installation of new GPS system, Anemometer and EM log. 

Subcontractors for Phase I are MSI Defense Systems Limited – 25mm gun mount and integration with new fire control, Ultra Electronics – electrical power systems, Sperry Marine – Radar, Raytheon – Fire Control and Navigation and Oto Melara – Main gun.

The Phase II, also called the JCPV Marine Engineering Upgrade Project was awarded to FF Cruz and Company Inc.  The contract encompasses the repair and remediation of the hull, overhaul and improvement of the Main Propulsion including control and monitoring systems, electrical plant, auxiliary systems, outfitting and hull furnishings and training the navy crew in the operation and maintenance of the new plant.

On another note, the PN has been working with local shipping companies to improve the maintenance capabilities of its Jacinto crews by temporarily posting crewmen on them
