The Philippine Navy (PN) is in the process of increasing its naval surface combat capability by acquiring new surface warships as part of the Horizon 2 phase. This includes the introduction of a new class of anti-submarine warfare (ASW) capable guided missile corvettes for the Offshore Combat Force (OCF) under the Corvette Acquisition Project.
This is in line with the PN's Desired Force Mix and Capability Upgrade Program, which actually calls for 12 Corvettes to be acquired between 2013 to 2028.

Overview:
The acquisition of Corvettes is among the most important programs of the Philippine Navy in beefing up its surface combat capabilities. Several versions of the PN's procurement plans from 2013 to 2028 included the corvettes, although total quantity and number of ships to be procured on which phase varies.
Based on the Philippine Navy's Desired Force Mix introduced in 2014 as a guideline for their Horizons 1 to 3 asset acquisition plan, the service hopes to get 12 corvettes capable of anti-submarine warfare (ASW). No specific timeline was provided on when these corvettes will be funded for acquisition.
In 2015, another Philippine Navy infographic was released on their official website, wherein 4 corvettes are planned for Horizon 2 phase (between 2019 to 2023), and another 4 as part of the Horizon 3 phase for a total of 8 corvettes.
The Philippine Navy's official publications released another list of plans on April 2016, wherein it included the plan to have 6 corvettes for Horizon 2 phase, and another 6 for Horizon 3 phase, totalling 12 corvettes.
Based on the submitted procurement plans of the Armed Forces of the Philippines on December 2016, it again included corvettes for the Philippine Navy, wherein 8 are planned for Horizon 2, and another 4 for Horizon 3 for a total of 12 corvettes.
Finally, based on the submitted plan by the Philippine Navy for approval under the Horizon 2 phase in 2017, only 2 Corvettes were requested for funding. And based on the approval released by Pres. Duterte last June 2018, this was approved with a proposed budget of Php28 billion.

30 September 2019:
MaxDefense released a blog entry discussing recent updates on the Corvette Acquisition Project, including what MaxDefense believes would be the direction of the project, which is for it to be designed and built by South Korea's Hyundai Heavy Industries (HHI) based on an improved variant of the Jose Rizal-class frigates (HHI's HDF-2600 design) being constructed now for the Philippine Navy.
We conveniently called this the Jose Rizal-class Flight II, based on how the South Koreans name the improved variant of their warship classes as the design progress.The blog entry can be accessed from the link provided below:
"Philippine Navy's Corvette Acquisition Program - Jose Rizal-class Flight II?" - first posted on 30 September 2019.

| Among those MaxDefense sees as most likely competitors to HHI's offer are Dutch shipbuilder Damen with their SIGMA 9814 corvette design (top) and a simplified version of the Gowind-class from French shipbuilder Naval Group (above). Photos credited to original sources. |
===============
09 November 2019:
As part of their report on the launching of the second Jose Rizal-class frigate Antonio Luna (FF-151) on 08 November 2019, News1 Korea reported that Defense Sec. Delfin Lorezana and top officials of Hyundai Heavy Industries signed a Memorandum of Understanding (MOU) on HHI's exclusive participation in the design and construction of a "new patrol ship" that the Philippine Navy will acquire next year.
There are only two new patrol / combat warship projects ongoing with the Philippine Navy, the Offshore Patrol Vessel (OPV) acquisition project and the Corvette acquisition project.
It was already reported before by MaxDefense that the Department of National Defense (DND) has already made the direction to acquire the OPVs from Australian shipbuilder Austal, while MaxDefense previously reported that Pres. Duterte has already approved the Corvette Acquisition Project last May 2019 with HHI's proposal being the one to be used as basis for the project.
Obviously the report was talking about the Corvette Acquisition Project, which means this firmly seals up HHI's selection as the shipbuilder and designer of choice for the Philippine Navy's next generation corvettes.
This proves that our earlier blog posted on 30 September 2019 was indeed correct, wherein we did mention that the DND and the Philippine Navy has set the direction to acquire the future new corvettes based on an unsolicited proposal submitted by HHI rather than with other shipbuilders.
The blog entry can be accessed from the link provided below:

===============
18 June 2021:
There are mixed reports and statements coming from both the Department of National Defense (DND) and the Philippine Navy (PN) regarding this project.
Due to COVID-19 pandemic expenditures of the government, the Corvette Acquisition Project was said to be delayed due to lack of funding. Despite proposals for the financing to be through soft loans from foreign governments, the Philippine Government still needs to raise an initial payment of around 10 to 15% of the total value of the project.
With this, it was mentioned by the DND in reports that the Corvette project will be pushed back to either 2022, or to the Horizon 3 phase of the RAFPMP which starts in 2023 and will be implemented by a different administration.
But other reports suggest that the project was merely delayed, but will still push through within the Horizon 2 phase. The Philippine Navy has also confirmed that the project is still ongoing.
MaxDefense Philippines also confirmed that the project is still alive, as the PN and DND are still discussing with foreign shipbuilders, specifically Hyundai Heavy Industries (HHI), ASFAT of Turkey, and some European shipbuilders.
The procurement still remains to be through soft-loan financing by the country of origin's government of the winning shipbuilder.
===============
22 July 2021:
MaxDefense Philippines confirmed that South Korea shipbuilder Hyundai Heavy Industries' new corvette design dubbed the HDC-3100, also known as the HDF-3100 frigate, is the model offered by the shipbuilder to the Philippine Navy's Corvette Acquisition Project.
Hyundai Heavy Industries updated its Naval and Special Ship Business Unit product brochure, and it interesting that they added a new ship design called HDC-3100.
Brochure says the length is 114m, width is 14.8m, and draft is 3.8m, with maximum speed of 25 knots. This makes it longer and wider than Jose Rizal-class frigates, but with the same speed which could mean the use of diesel engine propulsion only, no gas turbines.
HDC-3100 is an indication that it is a Corvette design (C in HDC), with a displacement of around 3,100 tons.
Based on CGI, the design is almost very similar to the HDF-2600, which is the baseline design of the Jose Rizal-class frigate of the Philippine Navy.
Differences noted on the HDC-3100 compared to HDF-2600 include:
* longer forward section
* larger space for more VLS launchers
* additional superstructure cover wall on mid-section for improved radar cross section reduction
* bigger space behind the funnel for more anti-ship missile launchers
The VLS on CGI shows 16 cells of what appears to be MBDA VL-MICA launchers, while space appears to be available for more VLS launchers.
The wall covering in the superstructure mid-section was what MaxDefense PH previously mentioned as something HHI can improve on the Jose Rizal-class design, although there is still an open gap forward of the funnel.
Access for davit-mounted RHIBs will be using a retractable access gate similar to most modern warship designs.
Also noted were increased number of countermeasure launchers, looks like Terma C-Guard similar to what PN uses on Jose Rizal-class frigates.
Another is the use of Hensoldt TRS-4D AESA radar which is a more advanced version of the TRS-3D used in the Jose Rizal-class frigates.
It remains to be seen if PN and DND will accept HHi and South Koran Govt's offer for the Corvette project, which is competing with other designs including from Turkey, Netherlands, and other countries.
===============
14 December 2021:
The Department of Budget Management (DBM) has finally released the SARO to support the funding for the 15% downpayment of the project.
SARO-BMB-D-21-0013357 dated and released on 10 December 2021 has an amount of Php3.75 billion, or around 15% of Php25 billion which is the budget allocated for Lot 1 - Platform and Launchers which involves the Corvettes itself and the weapon systems.
Lot 2 will still be funded separately, which has a budget of Php3 billion for the acquisition of munitions (missiles, torpedoes, etc).

23 December 2021:
Senior defense officials confirmed to Inquirer.net that the Notice of Award (NOA) has been released last 15 December 2021 for the Corvette Acquisition Project of the Philippine Navy, in favor of South Korean naval shipbuilder Hyundai Heavy Industries.
As mentioned before, HHI's HDC-3100 design was offered to the Philippine Navy to meet the requirements.
A contract is expected to be signed soon, with the DND and PN hoping to have it done before yearend.
Below is the report from Inquirer.net regarding this development:
===============
By: Frances Mangosing - Reporter / @FMangosingINQINQUIRER.net / 11:48 AM December 23, 2021
MANILA, Philippines — It’s official: South Korea’s Hyundai Heavy Industries (HHI) has secured a contract to build two corvettes for the Philippine Navy for P25 billion.
A notice of award was issued by the Department of National Defense (DND) last Dec. 15, two senior security officials familiar with the matter told Inquirer.net.
The development came shortly after the Department of Budget and Management (DBM) released funding for the 15 percent downpayment of the corvette acquisition project worth P3.75 billion last Dec. 10.
A contract signing could happen before yearend, said the senior officials.
The acquisition would be financed by a government-to-government loan agreement, Defense Secretary Delfin Lorenzana said in earlier statements.
HHI has been the favored supplier for the program since it was announced in 2019, based on statements of top defense and navy officials. The South Korean shipbuilder also built two multi-role frigates for the Philippine Navy in a P16 billion contract in 2016.
But the frigate acquisition project attracted public interest in 2018 after a conflict in the selection of the combat management systems (CMS), considered as the “brain” of the warships.
The disagreements stemmed from the failure of the shipbuilder to meet the original preference for a Link 16 compatible CMS by the Philippine Navy’s technical working group. In the end, the South Korean Ministry of Defense issued a guarantee that the ships’ CMS is compatible with Link 16 despite the absence of US certification, and the shipbuilder has offered to pay for the integration of the CMS to Link 16 when the Navy acquires this capability in the future.
The corvette acquisition project, which is estimated to cost P28 billion including weapon systems, is one of the big-ticket items in the Philippine Navy’s upgrade program. Plans to acquire the corvettes had been stalled last year because of the diversion of defense funds to pandemic response.
The warships would boost the country’s presence around the archipelago especially in the West Philippine Sea, where tensions continue to rise.
The Navy recently retired the last two of its World War 2-era patrol ships despite the lack of immediate replacements. Navy chief Vice Adm. Adeluis Bordado said the two corvettes and six offshore patrol vessels would see initial deliveries in two to three years.
===============
28 December 2021:
The Department of National Defense has signed a contract today with South Korean shipbuilder Hyundai Heavy Industries to build 2 new missile corvettes for the Philippine Navy.
The Corvette Acquisition Project is the Philippine Navy's most costliest project under the Horizon 2 Phase Priority Projects approved in principle in 2018.
Defense Sec. Delfin Lorenzana said having a HHI as the shipbuilder means ease of maintenance for both the new corvettes and the Jose Rizal-class frigates.
We reported before that HHI offered the HDC-3100 corvette/light frigate design.
No further details were provided, but it is expected that HHI will require to receive a Notice to Proceed (NTP) from the DND probably by January-February 2022, which is the starting date for the contract to start, and will also include the documents supporting the initial payment as part of the contract.
Based on the construction of the Jose Rizal-class frigate by HHI, it is expected that the process would be faster this time due to having no "issues" that resulted in investigations, as well as no opposition from the Philippine Navy on the subsystems to be used.
We expected the first frigate to start construction by mid-2022, and delivered to the Philippine Navy by mid-2024. The second frigate may start construction by 3rd or 4th quarter of 2022, and delivered to the Philippine Navy by 4th quarter 2024.

MaxDefense Philippines is still trying to get the full details of the ship's final fit-out, but the following are expected to be part of the ship's subsystems based on its analysis:
Weapon Systems:
* 1 x Oto Melara 76mm Super Rapid naval gun;
* 1 x Aselsan SMASH 30mm naval gun;
* 1 x Aselsan Gokdeniz 35mm twin close-in weapon system (CIWS);
* 2 x LIG Nex1 SSM-700K C-Star quadruple anti-ship missile launchers;
* 2 x SEA triple torpedo tubes for LIG Nex1 K745 Blue Shark torpedoes;
* a 12 or 16-cell VLS for still unconfirmed air defense missile system, most likely the MBDA VL MICA
* 4 to 6 12.7mm 50-cal heavy machine guns, most likely S&T K6;
Sensors:
* Hanwha Systems Naval Shield Integrated Combat Management System, still confirming if Baseline 2.xx or 3.xx.
* Hensoldt TRS-4D AESA air/surface search radar system, or equivalent;
* Hensoldt SharpEye X & S-band navigation & surface search radar system, or equivalent;
* Selex ES NA-25X Fire Control Radar, or equivalent;
* Safran PASEO NS electro-optical tracking system, or equivalent;
* still unconfirmed hull-mounted sonar, most likely ELAC Sonar Hunter 2.0
* still unconfirmed towed-array sonar system;
* Hanwha Link-P tactical data link.
===============
23 February 2022:
British defense company SEA has confirmed that it would supply the triple torpedo launchers for the 2 new HDC-3100 corvettes the Philippine Navy ordered from Hyundai Heavy Industries.
The SEA TLS will be installed on the new corvettes, 2 triple launchers on each ship. This is the same model used in the Jose Rizal-class frigates, which reflects HHI and PN's satisfaction with the torpedo launchers.
This is so far the first confirmation made by a subcontractor/supplier for the 2 new corvettes, and we are expecting more companies to release press statements in the next few months.
More on the report from
Naval News.

06 April 2022:
Hyundai Heavy Industries is tendering the Hull Structure and Fatigue Strength Analysis for the corvettes being built for the Philippine Navy.
It means a 3rd party would conduct these analysis for the HHI.
================
12 April 2022:
Hyundai Heavy Industries (HHI) updated its online product brochure for naval and special ships, which now features the ship design that will be used for the Philippine Navy's future corvette project.
The HDF-3100 frigate (previously also called the HDC-3100 corvette) is an enlarged version of the HDF-2600 design used for the Jose Rizal-class frigate, which confirms that the new corvettes are indeed larger and more capable than the Jose Rizal-class.
Also noted on the photo is a CIWS that appears to be similar to the ASELSAN Gokdeniz CIWS that MaxDefense Philippines exclusively reported before as the selected CIWS for the corvette (and potentially the Jose Rizal-class frigate as well).
While the main gun appears to be the Hyundai WIA 76mm model, we believe the Oto Melara 76mm Super Rapid gun will be used for the Philippine Navy.

===============
26 April 2022:
Hanwha Systems announced that they signed a contract to supply their Naval Shield Integrated Combat Management System for the Philippine Navy's 2 new guided missile corvettes being built by Hyundai Heavy Industries.
According to Hanwha System's displayed infographic in ADAS 2022, the new corvette would be using Hanwha's Baseline 4 series, which appears to be previously called Baseline 3.
 |
| Hanwha Systems' infographic posted in ADAS 2022 shows a "PN FFG" under Baseline 3, which is believed to be the Jose Rizal-class frigate based on the timeline of beyond 2015, and another "PN FFG" under Baseline 4, believed to be the HDC-3100 corvette with timeline beyond 2020. Photo credits to Hanwha Systems. |
This is actually confusing, since the infographic appears to show that further developments of Naval Shield's Baseline 2, most likely from Baseline 2.4 and above are now considered as Baseline 3, and the previously considered Baseline 3 was now pushed and renamed as Baseline 4.
It would be remembered that in past defense exhibitions and press releases, Hanwha Systems confirmed that the Jose Rizal-class frigate is to be equipped / equipped with Naval Shield ICMS Baseline 2. This can still be seen in Hanwha Systems' own website. |
| Photo credits to Hanwha Systems' website as of 26 April 2022. |
Surprisingly, the new infographic from Hanwha Systems did not show which CMS variant was installed/being installed on the Del Pilar-class frigates, which was labelled as "PN-DPCF" in previous infographics (see below).
Nonetheless, MaxDefense Philippines believes that the Philippine Navy would probably get the latest Naval Shield ICMS variant with the larger display screens, which was officially shown to the public in 2018.

==============
27 April 2022:
In a surprise move from Hyundai Heavy Industries, it appears that the new HDC-3100 corvettes they are building for the Philippine Navy will be getting the IAI Elta ELM-2258 Advanced Lightweight Phased Array (ALPHA) 3D AESA air/surface search radar, rather than the Hensoldt TRS-4D radar that was previously offered during the pre-procurement process of the project.
Based on the report from Israel media, IAI signed a contract with HHI to supply the radars for the corvettes, and would be integrated to Hanwha Systems' Combat Management System (HHI selected Hanwha's Naval Shield ICMS).
It remains to be seen if the changes were made with full approval by the Philippine Navy considering HHI's previous experience of "switching" its initial offer to a different model when they got the contract.
One can see the HDC-3100 CGI sporting a radar that closely resembles the TRS-4D with irs square-ish shape than the ALPHA 3D with its trapezoidal shape.
 |
| Note the trapezoidal shape of the IAI ALPHA antenna compared to the rectangular radar antenna found on the initial CGI photo of the corvette from HHI. Photo credits to IAI and HHI. |
Both HHI and PN are also very secretive on the specs of the radar they were looking for the new corvettes, unlike during the Frigate Acquisition Project where we can see the specs and what were offered.
It also remains to be seen if IAI Elta will supply the Basic or Extended variant of the ALPHA 3D radar for the Philippine Navy, with the Basic having an effective range of 200km, while the Extended variant at 400km.
In comparison, the TRS-4D has an effective range of 250km.
===============
30 April 2022:
Hyundai Heavy Industries displayed the scale model of the HDC-3100/HDF-3100 corvette that they are going to build for the Philippine Navy for its Corvette Acquisition Project.
And it is interesting that they showed it side-by-side with the HDF-2600 frigate design which is used for the Jose Rizal-class frigate.
Among the things noticed by MaxDefense Philippines and posted in its social media account:
1. It is obvious that the HDC-3100/HDF-3100 is longer than the HDF-2600, as the corvette is around 8 meters longer based on previous announcements by HHI.
The length of the VLS platform, the space for anti-ship missile launchers, and a longer helideck contributed to the increased overall length of the corvette.
2. MaxDefense Philippines previously noted that the helideck appears to be lacking in length on the HDF-2600/Jose Rizal-class that makes it less safe for longer helicopters like the MH-60R Seahawk to operate it. The increased landing deck appears to be now compliant to Sikorsky's recommended helideck length.
3. The cover on the superstructure mid-section (funnel area) was included in this new design which MaxDefense Philippines highlighted back in 2018, and its now really better looking and probably reduced the radar cross-section of the corvette compared to the HDF-2600/Jose Rizal-class.
4. The air/surface search radar panel now appears to be the same as the one used in the IAI Elta ELM-2258 ALPHA 3D AESA radar that was recently announced for installation on the new corvettes. Remember that initial CGI plus information from our sources initially point at the Hensoldt TRS-4D AESA radar which has a rectangular panel rather than trapezoidal as it shows now.
5. The secondary 30mm gun appears to be excluded in the corvette. This is surprising since the PN originally wanted 1 or 2 of them in each ship as improvement over the Jose Rizal-class, which only has 1 x 30mm gun.
6. The superstructure design on the helicopter hangar is also different from the HDF-2600/Jose Rizal-class. It is even more simplified due to the absence of the 30mm gun, allowing the CIWS to sit lower on the deck rather than on a pedestal.
7. 76mm gun looks like the Hyundai WIA model, but like what happened on the Jose Rizal-class, eventually the delivered model is the 76mm Oto Melara Super Rapid gun, which is the model selected by the Philippine Navy.

23 May 2022:
The DBM has released the project's 2nd milestone progress payment worth Php3,000,000,000.00 through a SARO issued on 20 May 2022.
This means the project has reached a milestone based on the Payment Schedule. While it is not known to us what the milestone is, MaxDefense Philippines has the Payment Terms and Delivery Schedule for the Frigate Acquisition Project which shows the payment milestones.
===============
30 July 2022:
The DND confirmed that First Steel Cutting of the first new HDC-3100 Corvette for the Philippine Navy would happen in 4th Quarter 2022, after Hyundai Heavy Industries and PN finalize and complete the Critical Design Review of the ships.
The Preliminary Design Review (PDR) was said to have been completed last week, and the Critical Design Review will start once the project's TIAC complete the review and accept the outcome of the PDR.
Based on how HHI built the Jose Rizal-class frigates, we believe HHI could also start the First Steel Cutting for the second corvette by 1st Quarter 2023.
HHI has a history of quickly building warships as shown by the recent launching of the latest KDX-III Batch 2 destroyer a few days ago after building the destroyer in just around 8-9 months.
It is then highly expected that HHI would launch the 1st Corvette by 3rd quarter 2023.
===============
10 February 2023:
Delays appear to have pushed back the start of construction of the first corvette for the Philippine Navy by Hyundai Heavy Industries.
As of January 2023, it appears that the Critical Design Review (CDR) for the ship design has not been completed yet, despite both the PN and HHI's experience in working together in the past, using a design that is not too far different from what they have worked with before.
But it was mentioned by the Philippine Navy that the First Steel Cutting for the first ship is scheduled to be made on May 2023, and the second ship by November 2023. This means a six month gap between the construction, and potentially on the delivery of the ships to the Philippine Navy.
===============
19 May 2023:
Hyundai Heavy Industries reached a milestone as it conducted the First Steel Cutting Ceremony for the Philippine Navy's Corvette Acquisition Project last 11 May 2023 at HHI's Ulsan Naval Shipyard.
This is for the 1st of two ships, which was previously announced to have its First Steel Cutting by May 2023.
Surprisingly the DND and PN both did not announce this, and the photo was released through the press by their sources.

21 March 2023:
Hensoldt UK confirmed they received 2 contracts from Hyundai Heavy Industries to supply Sharpeye Mk 11 navigation radars for Corvettes & OPVs for the Philippine Navy.
The orders total for 8 ships, which is quite significant for a single order for a 2nd/3rd rate navy.
Other PN ships using the Sharpeye Mk. 11 radars are 2 Jose Rizal-class frigates, 2 of 3 Del Pilar-class patrol frigates & 2 of the 3 Jacinto-class patrol vessel.
Commonality is key in this decision, not to mention Sharpeye is one of the best navigation radar for military application in the market, which can also be used as a secondary surface search and helicopter approach radar.

25 May 2023:
The Department of Budget and Management (DBM) has released the 3rd milestone MYOA payment for the Corvette Acquisition Project, with SARO-BMB-D-23-0017382 worth Php6,000,000,000.00 dated and released on 24 May 2023.
This is worth 24% of the project cost and was probably made after Hyundai Heavy Industries completed its first Steel Cutting Ceremony for the 1st ship of the class last 11 May 2023.
We expect another milestone payment to be made by November 2023 based on these developments.

French defense company Safran has confirmed during an interview by Naval News that the Philippine Navy's new corvettes and offshore patrol vessels will be equipped with the Safran PASEO XLR extra long range optronic identification & fire control system.
The system is an improvement from previous models including the PASEO NS used by the Jose Rizal-class frigates, and has been selected also by several other navies for their frigates including the French Navy's future FTI Amiral Ronarc'h-class frigates and Jacques Chevallier-class Logistic Support Ships, Brazilian Navy's Tamandare-class frigates, among others.

02 October 2023:
In a reply to Philippine News Agency, South Korean shipbuilder HD Hyundai Heavy Industries confirmed that they will deliver the first HDC-3100 corvette to the Philippine Navy by 2025, and the second ship by 2026, and that they are on-track with the delivery dates and construction of the ships.
HHI also confirmed that the First Steel Cutting ceremony for the 2nd corvette is scheduled this November 2023.
===============
22 November 2023:
HD Hyundai has reported that the first HDC-3100 corvette for the Philippine Navy has conducted the Keel Laying Ceremony, and the second HDC-3100 corvette held its First Steel Cutting Ceremony earlier today 22 November 2023 at its Ulsan Shipyard.
These are important milestones as the corvettes are scheduled for delivery to the Philippine Navy by 2025.
Based on the information released by HD Hyundai, the corvettes are now displacing 3,200 tons, 118.4 meters long, 14.9 meters wide, a cruising speed of 15 knots and a range of 4,500 nautical miles.
This is slightly larger than the original HDC-3100 design which is displaces at 3,100 tons, 116 meters long, 14.9 meters wide. Cruising speed and range remains the same as before.

05 April 2024:
The Department of Budget and Management has released a new SARO-BMB-D-24-0001675 dated 03 April 2024 worth around Php6 billion. This is the 4th milestone payment which brings total payment of Php18.75 billion to HD HHI.
===============
05 June 2024:
Looks like there was slip-up on the planned naming of the two new HDC-3200 corvettes of the Philippine Navy, based on uniform patch designs that were made available online for the Offshore Combat Force.
It appears that the ships will be named BRP Miguel Malvar (FF-06) and BRP Diego Silang (FF-07).
Among noticeable info are the hull designation, which shows that both ships will be designated as frigates (FF based on Philippine Navy's 2016 naming and classification standards), instead of corvettes.
This appears to be in line with information received by MaxDefense Philippines that the Philippine Navy is on advance stages of potentially acquiring "corvettes" to meet its requirements.
Also, Hyundai Heavy Industries itself also showed that designation of the ship design as frigate (HDF-3200) in some of their publications instead of HDC-3200.
Also, the hull number starts at 06 and 07, instead of anticipated 152 and 153 to follow the numbering of the 2 ''Jose Rizal''-class frigates.
Take note that these are not yet final naming and designations as the Philippine Navy may opt to change them considering the ships haven't been launched yet.

14 June 2024:
Another proof that the the HDC-3200 corvettes / frigates are indeed going to become the Miguel Malvar-class.
Here's the photo of the first ship of the class, which was previously identified as the future BRP Miguel Malvar (FF-06), seen in HD Hyundai Heavy Industries in Ulsan, South Korea.
The aft clearly shows the name "Miguel Malvar", which confirms that previous information were indeed correct.
Note that there seems to be no opening for Towed Array Sonar in the ship's aft, which was first noted on the Jose Rizal-class frigates. MaxDefense PH previously confirmed that towed array sonar will be Fitted for but not with (FFBNW) for the new corvettes and will be acquired separately. But we were hoping that space allocation were provided for them.
Surprisingly, the ship is already floating in the water, suggesting that it was already launched. There has been no announcement from the Philippine Navy, DND or HD HHI about such event, which is normally held with appropriate formal celebrations.

18 June 2024:
HD Hyundai Heavy Industries has launched the first HDC-3200 corvette for the Philippine Navy today 18 June 2024 in Ulsan, SK, confirming that it is indeed named Miguel Malvar (06).
It appears to have 2 x 8-cell or 12-cell VL MICA launchers, as well as an Oto Melara 76mm Super Rapid main gun. No Strales system as other pages claim.
FFBNW space appears to be enough for another 8-cell Mk.41 or KVLS, or another 8-cell or 12-cell VL MICA VLS (apparently a 8-cell VL MICA takes more space than an 8-cell Mk.41 or KVLS). The Gokdeniz CIWS is also seen w/o cover in the aft section.
The ship was reported to have a displacement of 3,200 tons, a length of 118.4 meters and maximum beam of14.9 meters, and a cruising speed of 15 knots (28 kilometers per hour), and a cruising range of 4,500 nautical miles (8,330 kilometers).

20 June 2024:With the availability of high resolution photo of future BRP Miguel Malvar (FF-06) during its launch, we are able to further dissect the ship and make our observations and analysis.
Here are some improvements we see in the Miguel Malvar-class (MMCF)compared to the Jose Rizal-class frigates (JRCF):
1. Mast layout for the Hensoldt Sharpeye Mk. Ii navigation/secondary surface search radar - the platforms are extended diagonally compared to JRCF which are position aligned to the middle of the mast.
2. The MMCF's mast is positioned further back from the bridge compared to the JRCF, and is now larger. Due to this, the Selex ES NA-25X Fire Control Radar is now positioned more forward rather than following the repositioning of the mast.
3. It appears that the MMCF are using a more advanced version of the Elbit Elisra Aquamarine electronic support measures (ESM) system compared to those in the JRCF. One of our contributors believe that this could be an improvement in making the system more compact compared to an earlier variant, benefitting from an earlier contract by Elbit Systems with the Royal Navy to supply a new system based on the Aquamarine ESM.
4. The decoy launchers now uses 12 tubes per side, compared to the JRCF which only have 6 tubes per side. It remains to be confirmed if MMCF uses the Terma C-Guard D-12T which is an improved variant of the C-Guard D-6T used in the JRCF.
5. One of our community member speculated that there could be a 30mm RCWS beside the Gokdeniz CIWS in the hangar superstructure's deck. But upon closer inspection, it seems not to be the case. It remains to be seen what it is.
