BRP Conrado Yap, a Philippine Navy (PN) corvette, detected a United States submarine that was submerged in the waters of Palawan in November 2019, in what was regarded as the first-ever submarine detection in the 121-year history of the country’s naval warfare service.

This was bared by no less than Navy Flag Officer in Command (FOIC), Vice Admiral Robert Empedrad during an interview with the media at the Naval Bonifacio Station in Taguig City on Wednesday night.

“The BRP Conrado Yap was able to detect a submarine while it was travelling in Palawan. That was the first time that it happened to our navy,” Empedrad said.

The Navy Chief said the crew manning the BRP Conrado Yap was on its way to Zamboanga for a “show the flag” mission, a naval event where a ship displays the flag of its country as an expression of patriotic pride, when it detected the American submarine.

Although Empedrad described the detection as “exciting,” he admitted that it is a big challenge for them.
 
“We don’t know what to do with it, it’s only a detection. What will happen in the near future? What are the doctrines involved here? Can you immediately fire a torpedo to destroy submarines? We have a lot of new capabilities that we didn’t have in our fleet before. Modernizing our navy is very challenging indeed,” The Navy Chief said.

“Sabi ko nga, kung tanggalin mo ‘yung dagat sa Pilipinas baka makakita ka ng 50 submarines sa paligid natin (If you remove all the water in the Philippines, you might see around 50 submarines around us),” he added.

Empedrad said they are continuously monitoring the submarine.

PHILIPPINE NAVY HISTORY: RPS SAMAR (PS-33) AGAINST UNIDENTIFIED SUBMARINE OFF LAMON BAY, QUEZON PROVINCE 12-14 NOVEMBER 1952:

By CDR Mark R Condeno

First published on my personal page in 2015 and republished at MaxDefense Philippines that same year.

Republished at Philippine Defense Discussion on 18 October 2018

Four years ago I wrote this short article on my FB page, marking the First Anti-Submarine Warfare conducted by the Philippine Navy...

POINTS to PONDER: The PLAN Submarine Force was established in 1947-1949 with former Soviet Submarines, while sightings of alleged Soviet Submarines in Southeast Asian waters at that time are reported in various newspapers of the era...

This was during the height of the HUK Campaign wherein relentless reports were provided to authorities regarding the sightings and surfacing of unknown submarines in the Polilio Island Area in Lamon Bay Quezon Province. Submarines are a valuable platform in providing supplies and ammunition to the dissidents on that period.

On 12 November 1952 an Intelligence briefing was conducted by the 2ND MILITARY DISTRICT under GEN EULOGIO BALAO AFP afterwhich the ships of the 1st PATROL CRAFT ESCORT (PCE) Division under LTSG Dioscoro Papa PN aboard RPS PANGASINAN (PS-31) comprising RPS SAMAR (LTSG Domingo Villamater PN) and RPS CEBU (LTSG Alfredo Peralta PN) (PS-28) positioned themselves at their designated patrol areas wherein PS31 in Casiguran Bay, PS28 in San Miguel Bay and PS33 in Lamon Bay.

On 13 November 1952 PS-33 detected on its radar - two converging vessels, in order to intercept, she positioned herself in the middle but lost contact with the other craft- (a 100 foot Submarine) at the range of 2,000 yards, in a few minutes they were able to regain sonar contact and released depth charges though no explosions were heard, sonar contact was again made the following day 0530H where in the intruder conducted evasive maneuvers and headed for deeper waters, Depth Charge were again released with the last one around 0610H which resulted to explosions.

PS-33's ASW-TRR was looked into examined by the United States Navy at Subic Bay and JUSMAG and noted that the Depth Charge was dropped at Beam Aspect and could have damage the submarine. This episode in Philippine Naval History marked the first Anti-Submarine Warfare conducted by the Philippine Navy with the end result for about 6 years no Submarine sightings were reported.

Then Defense Secretary Ramon Magsaysay lauded the skippers in preventing the re-supply of ammunition to the HUKS.

This milestone marked the essence of CONTROL OF THE SEA which is a valuable factor in any conflict. Most Submarine Surfacing or sighting reports of those days were in Celebes Sea, Sulu Sea, Sibutu, Palawan, Lamon Bay, Dirige Bay and in our Norther waters.

As backgrounder to the ships involved they were transferred from the USN to PN in May 1948: RPS SAMAR was scrapped in 1960, while RPS/BRP Pangasinan and RPS/BRP Cebu are still in active service. All ships belong to the Miguel Malvar Corvette Class whose namesake is named after the famous Batangueno General of the Philippine Revolution.

LOCATIONS OF UNIDENTIFIED SUBMARINE INTRUSIONS & SIGHTINGS IN THE PHILIPPINES FROM 1950's to 1970's....

I have included the Incident on the Chinese Huangfeng Class Missile Boat as a lot of of our countrymen could not believe that our Navy did it.

Should you have further info or additional areas were Submarine Sightings were reported please don't hesitate to comment.
