The Philippine Navy has embarked on the acquisition of a small fleet of diesel-electric attack submarines, which would allow the service to increase its combat capability, and taking advantage of submarine's use of underwater cover for deterrence and surprise attack against larger, more capable countries.
The Submarine Acquisition Project, currently the most expensive and most complicated project of the Philippine Navy, will provide the Philippine Navy with assets that even a small fleet of frigates may not be able to provide in terms of overall naval combat capability.
This resource page is expected to be longer than usual due to the discussion on the history of the Philippines' desire to have submarines.

Discussions and negotiations ongoing with Naval Group and French government, for final price, soft loan financing, and package inclusions. Discussions are also still ongoing with Daewoo Shipbuilding & Marine Engineering and South Korean government with the Jangbogo-I DSME-1400PN, and ASFAT and the Turkish government with the Reis-class (Type 214) submarine. As of 2022, only Naval Group and DSME continue to be in talks with the Philippine Navy. In 2023, the project was not awarded and was moved to Horizon 3 phase with an increased budget of Php97,000,000,000.00, equivalent to US$1.7 billion. Naval Group confirmed that it has revised its offer with the Scorpene-class but similar to Brazil's Riachuelo-class which is longer to accommodate more batteries, while DSME was acquired and changed name to Hanwha Ocean and made an offer on September 2023 with the KSS-III Jangbogo-III PN which is a downsized variant of KSS-III Dosan Ahn Changho-class without VLS and AIP (although AIP remains an option). Spain's Navantia also confirmed that it will be submitting an offer based on their S80 Plus Isaac Peral-class oceangoing submarine. Fincantieri was said to have offered the Type 212 Todaro-class.
Overview:
The Philippine Navy has been aspiring to acquire submarines since the 1950s, but has been unsuccessful in many attempts. Either the Philippines was restricted by the American government in acquiring submarine technology, and when this was lifted, the Americans has not been able to transfer submarines for believing that the Philippine government cannot support such capability.
In the early 1950s, the Philippine Navy requested for 3 World War 2 era diesel submarines from the US government, together with PBY Catalina flying boats. In the end, only the flying boats arrived, which were assigned later on to the Philippine Air Force.

In the 1970s, former Philippine Pres. Ferdinand E. Marcos expressed his desire to acquire submarines from other countries, specifically diesel-electric models from friendly countries like US and Germany.
For the past several decades, the US Navy has stopped operating diesel-electric submarines, and has converted to an all-nuclear submarine force. This has deprived the Philippines from getting surplus submarines from the US as nuclear submarines are a no-go for obvious reasons.
The last diesel-electric attack submarines of the US Navy, the Tang-class, were already almost 30 years in the late 1970s when the Philippine government requested for the transfer of at least 2 units as part of the 1977-1981 AFP Modernization Program. The request for them were rejected by the US government.

The submarine desire continued on until the 1980s up to the 1990s, when former Philippine Navy FOIC (now Maritime Academy of Asia and the Pacific President) Vice Adm. Eduardo Ma. Santos endorsed in 1998 the concept of the Philippine Navy having submarines under the AFP Modernization Program mandated by RA 7898 and approved in 1995, and opened up the possibility of acquiring midget submarines from Italy's Cosmo S.p.a. as a preliminary move, while moving on to conventional diesel-electric submarines in the near future. It also appears that the Philippine Navy sent officers to Pakistan to study their midget submarines built locally based on a design acquired from Italy.
Aside from that, the Department of National Defense even sent a Philippine Navy officer to study submarine design and construction in preparation for any future requirement to acquire new submarines.
The AFP Modernization Program from 1995 to 2010 passed without the Philippine Navy acquiring submarines, or even a meaningful surface fleet that it can actually say as modern. And it was only natural that submarines will again be floated for acquisition when the Revised AFP Modernization Program mandated by RA 10349 was approved in 2013.
In the Revised Philippine Navy Modernization plan as shown on the "Desired Force Mix" released by the PN in 2014, the plan was to acquire at least 3 conventional diesel-electric submarines within the 2013-2028 timeframe.

In 2015, another info-graphic was released by the Philippine Navy, again with the conventional diesel-electric submarine still in the acquisition plan, but clearly defined to be part of the Horizon 3 phase from 2023 to 2028.
Finally, another info-graphic was published by the Philippine Navy in their April 2016 official publications, indicating that the Submarines are integral part of the Surface Action Force of the Philippine Fleet. In a departure from previous plans, it now indicates that the Philippine Navy will need to acquire 6 submarines instead of just 3 to provide a better deterrent capability.
This was later on supported by the submissions made by the Philippine Navy for their Capability Plan under the Horizon 1 to 3 phases, wherein they submitted in 2016 a plan to acquire 2 conventional diesel-electric submarines within the Horizon 2 phase, and 4 more similar submarines in the Horizon 3 phase.
Between 2016 to 2017, further improvements were made by the Philippine Navy for their Horizon 2 and 3 phases proposal for submission to the Office of the President. With a new president at the helm of the country with promises to improve the Armed Forces of the Philippines into new heights, the Philippine Navy again tweaked their acquisition proposal under the Horizon 2 phase. Instead of just acquiring 2 conventional diesel-electric submarines, they now moved even more aggressively forward by instead requesting a fleet of 3 conventional diesel-electric submarines worth Php20 billion each, 7 Midget Submarines for Php5 billion each, and 6 two-man Swimmer Delivery Vehicles for Php35 million each.
Aside from that, the Philippine Navy has finally made a Submarine Group in its command under the Philippine Fleet, to allow the study of submarine and submarine warfare, as well as prepare the Philippine Navy in its acquisition of submarines. Officers and men assigned to this group were given the chance to study abroad on basics in submarine warfare as well as in submarine construction.
Unfortunately, the aggressiveness might be too much, as the proposal was shut down by Pres. Rodrigo Duterte and his economic team due to the high price of the proposal. The Philippine Navy was again requested to revise their program to under Php75 billion pesos only. The result of this became part of the recently approved Php300 billion Horizon 2 Priority Projects program, wherein the Philippine Navy is getting Php77.6 billion only.
In this approved acquisition program, none of the submarines proposed earlier were included. Not even the two-man Swimmer Delivery Vehicles was there. Instead, any submarine acquisition will be made in the Horizon 3 phase of the RAFPMP, which is scheduled from 2023 to 2028, or on a proposed 2nd List of Horizon 2 which will depend on the capacity of the government to pay for it.
Nonetheless, the Submarine Group continued to exist and continue its mandated task of preparing the Philippine Navy for submarine operations.
Then the unexpected happened when in June 2018, DND's Public Affairs Dir. Arsenio Andolong announced that Pres. Duterte and Defense Sec. Delfin Lorenzana has agreed to the request made by then Philippine Navy FOIC Vice Adm. Robert Empedrad to front-load the acquisition of at least 2 submarines into the Horizon 2 phase, using the 2nd List of Horizon 2 program.
No specific budget has been announced for the Submarine Project, but it is expected to be beyond Php40 billion for 2 submarines.
MaxDefense PH confirmed that it has documents showing that the Submarine Acquisition Project may go as high as Php75 billion due to the inclusion of construction of a new Submarine Base, a Submarine Training Facility, new support facilities for Submarine operations, and acquisition of equipment to support the submarine fleet.
This means that any submarine acquisition would be done through Government-to-Government (G2G) deal.
As early as the Submarine Group's formation, the Philippine Navy has already released a Request for Information (RFI) addressed to several international submarine builders to provide information about their respective products. This is to allow the Philippine Navy to determine what can be acquired with the proposed budget.
According to MaxDefense's sources from the Philippine Navy, among those that replied and provided information are Saab Group - Kockums of Sweden, ThyssenKrupp Marine Systems (TKMS) of Germany, Naval Group (formerly DCNS) of France, Daewoo Shipbuilding and Marine Engineering (DSME) of South Korea, and Rosoboronexport of Russia.
Based on information we gathered, the offers made by these shipbuilders were: a derivative of the A26 submarine design from Saab Kockums, the Type 209/1400, Type 210mod, and Type 212A from TKMS, a derivative of the Scorpene-class from the Naval Group, the KSS-I Chang Bogo-class (Improved Type 209/1400) from DSME, and the Project 636 Kilo-class from Rosoboronexport.
Aside from providing information on their submarine products, these shipbuilders already came forward with providing different offers to the Philippine Navy. It appears that numerous meetings have already been made between the Department of National Defense and/or the Philippine Navy, and these foreign shipbuilders or their counterpart defense ministries.
By 2019, based on the statements of the DND and Philippine Navy officials, the PN appears to have already shortlisted its plans between DSME's offer (supported by the South Korean government), and the Naval Group's offer (supported by the French government).
A decision has become apparent by 2020, with the MaxDefense PH reporting that the Philippine Navy has stronger preference on the Naval Group proposal with the Scorpene-class submarine. No Air Independent Propulsion (AIP) system would be included, using the CM-2000 conventional design variant.

A credit line was also proposed by the French government to allow the acquisition despite the lack of funding from the Philippine side. This would be paid in multiple years, and would be low interest and may even include a counter trade offer.
But as of early 2023, no award has been made to Naval Group, despite the company setting up a satellite office in Manila in 2020. A confirmation from the Philippine Government was made by early 2023 that the project has been moved to the Horizon 3 phase of the Revised AFP Modernization Program covering years 2023-2027. While the project was moved back, the budget was increased to Php97 billion (approx. US$1.7 billion), for still the same requirements.
This has allowed Naval Group and DSME (now Hanwha Ocean after the company was acquired on December 2022) to improve their offers.
As of June 2023, Naval Group has confirmed that its offer is still based on the Scorpene-class diesel-electric submarine but will have a 10,000 nautical miles maximum range, and an endurance of 80 days, which is similar or better than the Brazilian Riachuelo-class variant.

Spanish shipbuilder Navantia has released information in August 2023 that they will be making a formal offer to the Philippine Navy based on their S80 Plus Isaac Peral-class oceangoing diesel-electric submarine, and will include the design and construction of submarine basing and training facility in Ormoc, Leyte province, assisting in formation of the Submarine Force, submarine training in Spain including training with the Spanish Navy, low-interest, long term financing and guarantee from the Spanish Government, and others.
Meanwhile. Hanwha Ocean has confirmed in September 2023 that they are upgrading their offer from the KSS-I Jangbogo-I (DSME-1400PN) to the KSS-III Jangbogo-III PN, which is a downsized variant of the KSS-III Dosan Ahn Changho-class built for the Republic of Korea Navy.

It also highlighted the use of modern Lithium-Ion batteries instead of lead-acid batteries found in its competitor's offers, allowing for longer endurance, longer lifespan, shorter and easier servicing, faster charging and slower discharging.
This time they were very specific on providing 4 different submarine training simulators (Submarine Tactical Trainer, Submarine Control Trainer, Basic Operations Trainer, and Virtual Reality Trainer), as well as providing Advanced Operation Training and Advanced Maintenance Training in the Philippines. They also touted the Total Operations & Maintenance Support System and Center including guarantee of spare parts availability through its planned formation of a "Global Janbogo Submarine Supply Chain" which will allow all South Korean-made submarine users to share spare parts and have annual meetings similar to how the US Navy have their own International Frigate Working Group for all navies using the Oliver Hazard Perry-class frigate.
It is unconfirmed though if South Korea will still be offering to transfer one of its older KSS-I Chang Bogo-class submarine to the PN at a later date if it selects Hanwha Ocean's offer.

01 December 2020:
Our parent page MaxDefense PH confirmed that a delegation from the Department of National Defense (DND) and Philippine Navy led by Defense Undersecretary for Acquisition and Resource Management USec. Raymundo Elefante and Philippine Navy Flag Officer in Command Vice Admiral Giovanni Carlo Bacordo, made a trip to South Korea to visit the Republic of Korea Navy's Submarine Force Command and shipbuilder Daewoo Shipbuilding & Marine Engineering (DSME) on November 2020.
Discussions were made between the 2 parties with regards to the planned acquisition of submarines by the DND for the Philippine Navy, with the Korean government offering a solution based on the DSME-1400 submarine.
The DSME-1400 is based on the German Type 209/1400 design, and is called the Chang Bogo-class in the Republic of Korea Navy. The Indonesian Navy also operates an improved version of the type now known as the Nagapasa-class.
South Korea remains one of the countries shortlisted to supply the submarines, the others being France and another European country.

14 March 2021:
The Philippine Navy, led by its FOIC Vice Adm. Giovanni Bacordo, visited the French Navy and met with his French counterpart French Navy Chief of Naval Staff Admiral Pierre Vandier at Ecole'Militaire, Paris, France.
The PN was briefed on French Navy thrust and direction, and French submarine organization and capability.
Further, the Staff-to-Staff discussions on French submarine organization and capability concept has provided important inputs of utmost consideration in the establishment of Philippine Navy’s Submarine Force. Joining Vice Admiral Bacordo during the bilateral talks are Capt Edwin M Nera, Commander, Submarine Group and Capt Emerson C David, Director, PN Modernization Office.
Significantly, the Chief of the French Navy has expressed support in the efforts of the PN in capability development, wherein their Directorate for General Armaments (DGA) and Défense Conseil international (DCI) can assist for the aspects of acquisition and training, respectively.

04 April 2021:
MaxDefense posted an article from the French government confirming that the French Treasury Ministry has been in talks with the Philippine government regarding the use of French financing for the acquisition of submarines and building a submarine force for the Philippine Navy.
The visit a few weeks ago by French Ambassador to the Philippines Michelle Boccoz to the Philippine Department of National Defense and meeting with Defense Sec. Delfin Lorenzana actually gave focus to this, considering the PN's visits to Naval Group and the French Navy.

29 April 2021:
AFP Chief of Staff Gen. Cirilito Sobejana is in Turkey to visit officials from the Turkish Ministry of Defense. Gen. Sobejana trip to Turkey also includes a visit to ASFAT's office and facilities in line with their offer to the Philippine Navy on shipbuilding programs, including the Submarine Acquisition Program.

ASFAT is offering transfer of technology, training and technical know-how, logistics and maintenance support, and assisting in designing and constructing a submarine base and training facilities as part of a package.
The Turkish government is also offering a financing option to allow the DND and PN to proceed with the submarine procurement despite financial difficulties due to COVID-19 related expenses of the Philippine government.
International defense media outlets have reported that Philippines Department of National Defense (DND) Assistant Secretary on Logistics and Acquisitions ASec. Jesus Rey Avila has visited the Republic of Korea Navy's Submarine Force Command, as well as Daewoo Shipbuilding and Marine Engineering (DSME).
He also had meetings with officials from the South Korean Defense Acquisition Program Administration (DAPA) and Korean Export-Import Bank (KEXIM).
Meetings with the ROKN Submarine Force Command included discussions on transfer of know-how on submarine operations to the Philippine Navy, resumption of International Submarine Education and Training Program (ISETP) that has been put on hold due to COVID-19, and regular Navy-to-Navy talks on submarines.
Meanwhile, ASec. Avila also visited DSME's facilities and discussed with officials regarding the Total Solution Package offer for the Philippine Navy's Submarine Acquisition Project. This package includes the DSME-1400PN (Improved Chang Bogo-class, with further improvements compared to the Nagapasa-class of the Indonesian Navy), financing and soft-loan, training, logistics support, and assistance in construction of submarine basing facilities.
The meetings with DAPA and KEXIM officials were related to the soft-loan financing for the submarine package, and support from the South Korean government on the project.
This is actually a surprising move since the Philippine Navy, as well as Defense Sec. Delfin Lorenzana has been very vocal in their previous statements that France's package offer with Naval Group's Scorpene-class submarine were the preferred choice by the Philippine Navy.
France's offer is quite similar to the South Korean offer, although MaxDefense PH sources from the Philippine Navy confirmed that the submarine itself is key to the decision, as the Scorpene-class is believed to be a better submarine in terms of capability compared to the older DSME-1400 design, which is actually an upgrade version of the German Type 209/1400.
MaxDefense PH also confirmed that if price would be a major factor, the South Korean offer is definitely cheaper than the French offer, to the point that the South Koreans may offer up to 3 submarines for a little over the French's offer for 2 submarines.
Only issue that PN officials are concerned is that the DSME-1400 appears to have problems with the Indonesian Navy, known as the Nagapasa-class. The decision of the Indonesian Ministry of Defence to cancel its deal to build another batch of 3 submarines, as well as problems being reported on the Nagapasa-class were taken into consideration by Philippine Navy leaders and technical team.

02 February 2024:
The Philippine Navy's spokesman confirmed that the Submarine Acquisition Project is indeed included in the Re-Horizon 3 phase of the Revised AFP Modernization Program.
Although he did not confirm how many submarines are included, he mentioned that the Philippine Navy should have between 2 to 3 submarines.
He also mentioned that offers were made from France, South Korea, Spain and Italy, without being specific on the submarine models and shipbuilders involved.
Our parent page MaxDefense Philippines checked with sources and received confirmation that Italy's Fincantieri was the Italian proponent, offering a variant of the Type 212 Todaro-class diesel-electric attack submarine.

The Type 212 is a German design and it also remains to be seen if Germany has no objections for Italy to market a derivative of their design.
No further details were provided as to what is the extent of Italy's offer nor any updates on the offer from other shipbuilders. As of late 2023, it was confirmed by naval sources to MaxDefense Philippines that only Naval Group submitted the most comprehensive offer.
