The Philippines is continuing its upgrade and enhancement of radar air surveillance coverage across the archipelago.
On 20th September it was reported that the radar capabilities in the north of Luzon, the largest island in the Philippines would be increased. The investment into radar is intended to enhance the coverage of the West Philippine Sea, along with the wider Pacific area.
There is no word yet on what the radar acquisition will consist of in terms of radar type, number to be acquired, budget and programme timelines. However, as reported in the January 2013 edition of ChainHomeHigh, the Philippines Air Force (PAF) has announced plans to acquire three ground-based air surveillance radars.
This news follows an announcement in March 2012 that the PAF would perform a wide-ranging modernisation to include the acquisition of six combat aircraft, twelve trainers, long-range maritime patrol aircraft and a single air defence radar.
The announcement regarding the new radar (made in December 2012) now seems to indicate that the quantity of air defence radars to be purchased has been increased to three.
Little is known regarding the ground surveillance radars which the PAF currently operate, although it is thought that the force has at its disposal possibly around 20 ITT Gilfillan (now ITT Exelis) AN/TPS-32 long-range surveillance systems. Only a single system based at Wallace Air Station, a former United States Air Force facility located on Luzon Island in the northern Philippines is thought to be continually at work. This radar is believed to provide surveillance of the northern approaches to the archipelago. The AN/TPS-32 has a range of 556km (300 nautical miles) and a 100,000 feet (30,500 metre) ceiling.
Based on the performance of the AN/TPS-32 it is possible that the PAF is seeking a long-range, high-altitude radar which can be integrated into the overall Philippine Air Defence Identification Zone which is commanded by the PAF Air Defence Alert Centre, controlled by the Air Defence Wing based in PampangaProvince in the south of Luzon island.
