The Philippine Navy (PN) and the Philippines' Department of National Defense (DND) have recently been very open in its planned acquisition of assets under the Horizon 2 phase, including how they plan to acquire assets, or from where are they planning to acquire them.
In the case of the PN, among the priorities that it had already mentioned publicly are the acquisition of brand new Corvettes, Offshore Patrol Vessels (OPV), Landing Platform Docks (LPD), Missile-armed Fast Attack Interdiction Crafts (FAIC-M), and Submarines.
Out of the projects above, only the Landing Platform Dock project will be acquired through Public Bidding, and the bidding process is still ongoing as this entry was written. All others are to be acquired through Direct Negotiations or Government-to-Government (G2G) deals between the DND and its foreign counterparts.
MaxDefense believes that out of those in the list for G2G procurement, the Corvette and Offshore Patrol Vessel projects are the most urgent ones. But in this case, let's only talk about the updates on the Corvette Acquisition Project.
With the awarding of the project happening very soon, it would be fitting for MaxDefense to discuss the project again based on newer information.

Recap on the Corvette Acquisition Project:
Since MaxDefense posted its last blog entry on the Corvette Acquisition Project more than a year ago on May 2018, let's have a recap of what the project is and what is it all about.
Previously MaxDefense posted information on what we believe would be the general technical requirements of the corvettes based on information we gathered back then. Here are what we posted back in 2018 just for readers to recall:

- Damen of the Netherlands with their SIGMA small warship family,
- Hyundai Heavy Industries (HHI) of South Korea with a modified design based on the HDF-2600 / Jose Rizal-class frigates,
- Garden Reach Shipbuilders & Engineers (GRSE) with their a modified Kamorta-class design,
- Daewoo Shipbuilding & Marine Engineering (DSME) with a new design based on the larger Daegu-class frigates;
MaxDefense was also told that other shipbuilders like Naval Group of France, Navantia of Spain, Saab Kockums Naval Solutions of Sweden, and Goa Shipyards of India have shown interest to submit their offers.
Updates on Technical Requirements:
Just before the end of 2018, MaxDefense received a more accurate general technical requirement on the Corvette Acquisition Project, which further refined what were being asked for the proponents to provide compared to the requirements prior to that.
While the revised requirements did not went too far from the earlier list we posted above, this gave us more clarity on what the Philippine Navy would want in their corvettes, as follows:
- Minimum length of 80 meters, no limit on maximum length;
- A draft of equal or greater than 4 meters,

So far, the requirements above are actually close to global standards of current corvette designs, and was actually an improvement over the Jose Rizal-class frigate that Hyundai Heavy Industries (HHI) is set to deliver to the Philippine Navy next year.
Among the most notable differences with the Jose Rizal-class are the following:
* Use of a 3D AESA radar, which they learned when HHI replaced the 3D AESA radar it offered during the bidding to a different radar model using older technology. Specifying an AESA radar would force the proponent to provide it in their offering.
* Inclusion of a Towed Array Sonar System (TASS) which would effectively improve the ship's submarine-hunting capability instead of just relying on a Hull-Mounted Sonar. In the Jose Rizal-class, this is a Fitted For But Not With (FFBNW) item.
* The specs includes the incorporating of Tactical Data Link 16 and 22, which the Philippine Navy would supply but the shipbuilder should allow easy integration into its system. Mistakes in the Frigate Acquisition Project on being not too specific on this matter resulted to allowing a product not proven to integrate with Link 16 to be used.
* Use of Long Range Acoustic Device (LRAD), which enables voice communication to be made in long distances, which is good for law enforcement missions. It is also a good defensive sound weapon against terrorists, illegal fishermen, and others.
* Requirement for an Unmanned Aerial Vehicle component, which will actually extend the eyes and ears of the warship by improving surveillance and camera range, and can also be used for targeting over the horizon for the ship's anti-ship cruise missiles.
* Increased quantity of anti-ship missile launchers from 4 to 8, which was one of the issues of the Jose Rizal-class when the PN decreased the requirement to just for 4 launchers to fit the tight budget. In today's improving electronic warfare, hard and soft kill systems, launching a single or even two anti-ship missiles against a capable surface warship might not necessarily equate to a sure kill.
* Requirement to include at least an 8-cell VLS and a CIWS, both of which are FFBNW items in the Jose Rizal-class. This means the corvettes would be ready to receive short or medium-range surface-to-air missiles that improves the warship's overall capability on the get-go. Based on how slow the PN does procurement, we do not expect the Jose Rizal-class to have their VLS and CIWS in the next 2-3 years.
* Requirement to include Communication-EMS which is another step forward from just relying on Radar-ESM for identification, detection and interception of electronic signatures, as in the case of the Jose Rizal-class and Del Pilar-class ships.
Aside from these major differences, it appears that the Philippine Navy is looking for a warship design that is smaller than the Jose Rizal-class but will have more equipment installed once delivered.
Considering the higher budget provided for the Corvette Acquisition Project than on the construction of the Jose Rizal-class frigates, it is expected that the corvettes will have additional or even better subsystem fit-out, more weapons and sensors, and will be benefiting from experience from the design and construction of the frigates.
Up until the pre-procurement phase, MaxDefense noted that only certain shipbuilders really pursued the project with seriousness, and these are:
- Hyundai Heavy Industries (HHI), with a derivative of the HDF-2600 / Jose Rizal-class design;
- Damen, with the SIGMA family, with offers ranging from the SIGMA 9813, 9814, and 10514 designs;
- Naval Group with the Gowind-class corvette design;
- Goa Shipyard with a derivative of their Saryu-class offshore patrol vessel;
- Turkish Ministry of Defense with a derivative of the Ada-class corvette;
HHI's offer is technically a design based on Jose Rizal-class frigates, but will need to be revised to meet the requirements. They have the highest chance of being selected since they already have experience working with the Philippine Navy, and will not have difficulty in having a final design approved due to its similarity to the Jose Rizal-class. Their quick construction turn around as shown on the construction of the Jose Rizal-class is also something that has been noted well by both the DND and PN. Another advantage is their ability to help the Philippine Navy lobby for the transfer of excess warships from the South Korean government.

Damen has offered several designs of their SIGMA family of small warships, with MaxDefense believing that the SIGMA 9814 originally offered to Vietnam being the most feasible based on the requirements. It has partnered with local marine contractor Propmech Corporation and was looking at other local shipbuilders for partnership that would allow them to build some of the corvette's modules locally, and probably have the ship assembled locally too. Damen has an existing shipyard in Vietnam and agreements with PT PAL in Indonesia, which could ether be a good or bad news depending on their benefits or disadvantages.

Goa Shipyard Ltd. benefits from its participation on the Brazilian Navy's Tamandare corvette project, offering the same platform to the Philippine Navy as what they offered to Brazil. Based on feedbacks from our sources, Goa's offering was said to be the cheapest, but concerns on using an offshore patrol vessel design rather than a derivative of a small warship design could be an issue.

Other shipyards did provide offers but were not really serious due to different circumstances. This includes ThyssenKrupp Marine Systems (TKMS), Navantia, Fincantierri, Austal, BAE Systems, Mazagon Dock, and STX.
Months leading to the Project Approval:
MaxDefense received confirmation as early as March 2019 that Hyundai Heavy Industries appears to be the leading shipbuilder in the race to build the PN's new corvettes. This was after Naval Group and Damen was said to have lost interest in the project for reasons MaxDefense would rather not discuss in the public.
The Turkish government was said to have been pushing hard for their offer to be shortlisted, but it appears that decision makes within the DND and PN were already fixed on who would be the selected shipbuilder.
MaxDefense's sources later on confirmed that HHI's offer was the most favoured for a number of reasons both legal and, as our sources mentioned, "obvious extra-legal" reasons that is related to how the Philippine Navy and DND ended up on dealing with HHI for the Jose Rizal-class frigates in 2016-2017.
HHI's latest offer was considered "unsolicited", as it was not tailor-fitted based on the Philippine Navy's posted requirements. Instead, it was a combined offer by HHI with backing from the South Korean government that not only covers the construction of the corvettes and the subsystems in it, but also other issues like defense cooperation, excess defense article, financing, and other matters that may include political reasons. For discussions, let's focus on the reasons they does not involve "extra-legal" matters.
It was later on confirmed that during the Joint Command Conference in Malacanang last 07 May 2019, Defense Sec. Delfin Lorenzana submitted for the DND's project approval proposal and recommendation based on HHI's unsolicited offer, which means that it was already evaluated and selected by both the PN and DND beforehand. It validated earlier information provided to MaxDefense on HHI's offer being the most likely selection.

Pres. Duterte gave the green light to proceed with the Corvette Acquisition Project based on HHI's unsolicited offer, which means the DND and PN were given the freehand to finalize negotiations with HHI and the South Korean government.
HHI's Unsolicited Offer: Jose Rizal-class Flight II
According to MaxDefense's naval and defense sources, the HHI offer was actually an improved Jose Rizal-class frigate, with enhancements made on the sensors and subsystems, performance, weapon systems, and added features that goes with the ship.
It is expected to have a similar hull and base design as the Jose Rizal-class, but might have some adjustment in terms of displacement, length and width, and other physical dimensions to allow the added features or replaced subsystems.
It is safe to say that the corvettes offered by HHI are actually a follow-on to the Jose Rizal-class, which can be labelled as Jose Rizal-class Flight II considering South Korea has been doing a similar method of improving an existing design as they are built in numbers. In this case, it is highly possible that HHI is still constructing / fitting-out the Jose Rizal-class frigates once the contract for the corvettes are signed.
Due to these changes, MaxDefense now believes that these corvettes could be larger and heavier than the original Jose Rizal-class frigates. Among the changes that we expect are the use of larger diesel engines, having larger fuel tanks, more spaces and allowance for weight and power for additional weapon and sensors, more or larger diesel generators, possible use of alternative power sources to compensate on the additional weight, and more crew and storage spaces to accommodate more crew.
Being unsolicited, it is highly possible that HHI would either have fixed the subsystems to be used, or will allow the Philippine Navy to choose but up to a certain degree of not exceeding specific budget allocations unless the PN shoulders or agrees to pay more. At best, it may still follow the basic requirements of the Philippine Navy like the use of a 3D AESA radar, etc.
Up until June 2019, the PN is still in negotiation with HHI on the final fit-out of the corvettes, including additional subsystems that were not part of the proposal. Apparently HHI's offer may not have exceeded the budget allocated by the Philippine Navy, which is now pegged at Php24 billion (US$ 461 million) for 2 corvettes (or an average of Php12 billion or US$230 million per ship) excluding ammunition which will be acquired under a separate sub-lot worth Php4 billion.
Additional Pohang-class Corvettes on the Table:
Among the inclusions made by HHI for the Philippine Navy and DND to consider was that they will again lobby for the transfer of more retired Pohang-class corvettes to the Philippine Navy if their HHI is awarded the project.
This is exactly the reason why the Philippine Navy and DND were both confident that their request for 2 more Pohang-class corvettes, and possibly more units will be granted by the South Korean government.
So far, not even the French, Indian, or Turkish offers could match that.
The introduction of more Pohang-class corvettes means the Philippine Navy could now have reason to decommission and dispose of its remaining World War 2-era warships like the Rizal-class and Malvar-class patrol vessels by 2020.
MaxDefense's Opinion and Forecast:
MaxDefense believes that since HHI was the one that made the proposal, it is highly possible that it would include subsystems that are made in South Korea. It may also have features found on the new Daegu-class frigates of the Republic of Korea Navy, although it could be using more imported components than its Korean counterpart.
Among those expected to be carried over from the Jose Rizal-class frigates are the following:
* Combat Management System, which may still use the Hanwha Defense Systems Naval Shield I-CMS. Since development of Baseline 3 is not yet completed, it is highly possible that the corvettes will receive a later version of Baseline 2.
* Anti-ship Cruise Missile with the LIGNex1 SSM-700K C-Star missile. Among all weapons, the C-Star is the most likely Korean weapon to be made standard on the corvettes.
* 76mm Naval Gun using the Oto Melara 76mm Super Rapid gun, which is becoming the standard naval gun of the Philippine Navy together with the older Oto Melara 76mm Compact gun.
* 30mm Secondary Gun using Aselsan SMASH 30mm RCWS, which still remains to be one of the most affordable in the market. Having them already in the Jose Rizal-class makes it more feasible.
* SEA Triple Trainable Torpedo tubes, which also makes sense due to commonality.
* Lightweight Torpedoes with the LIGNex1 K745 Blue Shark lightweight anti-submarine torpedoes, which is also becoming the standard lightweight torpedo of the PN,
MaxDefense is also expecting improvements, including the following:
* 3D AESA radar using the Hensoldt TRS-4D radar, which is essentially an AESA version of the older non-AESA TRS-3D installed on the Jose Rizal-class.
* The K-VLS 8-cell Vertical Launching System, wherein the frigates may be fitted with at least 1. Should the PN be successful of having two 8-cell VLS, it is still highly possible that at least 1 could be using the K-VLS to allow the use of Korean-made missiles. This means possibly offering also the LIGNex1 K-SAAM Sea Bow anti-missile missile system, and/or the LIGNex1 KM-SAM Cheolmae 2 medium range surface-to-air missiles.
While still unconfirmed, among those that were being considered for inclusion on the new corvettes include two 8-cell VLS for surface-to-air missiles, diesel-electric hybrid propulsion for silent running during ASW operations, an additional 30mm naval gun, a more comprehensive Electronic Warfare suite, among others.
Corvette or Frigate?
If the new corvettes are essentially slightly larger Jose Rizal-class frigates, does it mean that they are actually frigates and not corvettes?
Or since the new corvettes the same or slightly larger than the Jose Rizal-class frigates, does it mean the Jose Rizal-class are actually corvettes and not frigates?
Considering the Philippine Navy plans to have 6 frigates and 12 corvettes as part of its Sail Plan 2028, where do we categorize the new corvettes and Jose Rizal-class frigates?
If MaxDefense is to answer the question, I believe the Jose Rizal-class should be reclassified as corvettes, and the new corvettes remain as corvettes too.
Why, you ask? Despite the classification of both ships becoming moot due to similarities in capabilities and size? Simple.
First of, if the Philippine Navy classifies them as corvettes, they are now compelled to acquire larger warships that they can classify rightfully as frigates. It won't matter if by paper the Philippine Navy becomes frigate-less until 2023. At least we know that the PN would now be looking at larger warships, with length probably exceeding 120 meters and displacement exceeding 4,000 tons, with more space for power generation, larger and more powerful sensors, and more capable weapon systems.
Secondly, the PN has to base its classification on the actual ability of the ships As per the PN's Classification Guidelines as of May 2016, a "Corvette" is a surface ship designed for anti-submarine warfare, and displaces between 540 to 3,000 tons (or well within the displacement of both the Jose Rizal-class frigate and the new corvettes).
Meanwhile a "Frigate" is a surface ship designed for both ASW and Anti-Aircraft Warfare (AAW), and displaces between 2,000 to 5,000 tons. Despite the Jose Rizal-class frigates slated to have an 8-cell VLS, that would not be enough for it to be classified as an AAW asset, since the missiles are most likely just to defend itself against incoming aircraft or anti-ship cruise missiles. A real AAW asset means having the capacity to provide air defense not just to itself but also an entire battle group, and having longer-ranged air defense capability. This means being armed with more VLS launchers, more powerful air defense radar and combat system, and use of long range air defense missiles like the Barak-8, Aster-30, or SM-3 missiles.
Lastly, if a more powerful ship like the new corvettes are classified as corvettes, is it not logical to classify less powerful and probably slightly smaller warships like the Jose Rizal-class as corvettes too?
And the Philippine Navy must have already realized this before too. Why is that?
Based on the original submissions made by the Philippine Navy to procure additional frigates as part of the Horizon 2 Priority Projects, they have actually allocated a budget of Php18 billion (around US$380 million in 2016, most likely excluding ammo) for each future frigate in 2016. That is far higher than the current allocation of Php12 billion (around US$230 million in 2019, excluding ammo) for each new corvette, or the Php8 billion (US$170 million in 2016 excluding ammo).
It would also be remembered that Philippine Navy Flag Officer in Command Vice Adm. Robert Empedrad, in a recent press interview, mentioned that a new large frigate may cost around Php60 billion (around US$1.15 billion). Although his cost estimates were too high (even European navies pay less than US$1 billion for AEGIS-equipped air defense frigates), the idea is that they are looking at frigates with similar capabilities and obviously larger size than the new corvettes or the Jose Rizal-class frigates in the future.
MaxDefense will try to monitor this project, considering everything can still change since there is no contract nor even a Notice of Award released in favor of any shipbuilder. MaxDefense was told by sources that the NOA could be released before the end of October 2019, with a contract potentially ready for signing before the 2019 Christmas Holidays kick in.
More of the updates coming on the Corvette Acquisition Project will be posed by MaxDefense in its resource page for the project. It can be accessed on our website's AFP Modernization Projects portal, or through the link provided below:
