Arguably, this gun would be a derivative of the Oto Melara gun used on our Del Pilar class frigates and Jacinto class patrol vessels.

The 76mm Oto Melara gun has been the subject of many threads on the now defunct Timawa.net forum, and more recently, was central to this proposal:

GUNNEX for the anniversary of the Battle of Leyte Gulf

This was not merely for entertainment purposes. This relatively common-place weapon system, among western-oriented navies, is arguably the most visible indicator of the state of the Philippine Navy's logistical prowess and the technical acumen of its personnel. As such demonstrations of their operational status during Gunnery Exercises (GUNNEX) therefore is important.



The following is an excerpt from a Joint Staff Command College paper on the state of training in the Philippine Navy, dated 10th of January 2001.

Quote
When Hong Kong was turned-over to Mainland China in 1997, the Philippines was able to procure three Peacock Class Patrol Vessels (PCPV) at a friendship price from the Hong Kong Squadron of the British Royal Navy.

Although the Philippine Navy initiated the deal, it was not included in the PN Operating Program and Budget. Hence, its British crew haphazardly
conducted the necessary training of both PN officers and enlisted men assigned to man the three ships.  These three former British ships became the most modern ships in the Philippine Fleet although they are relatively obsolete compared to the standards of the most modern navies around the world.

The ships are not yet equipped with the missile system and an airborne CIC that would extend the effective ranges of its sensors and weapons beyond the horizon. Its main armament is 76-millimeter Otto-Melara gun equipped with fire-control radar and auto-reloading system. One man stationed at the console of the fire control radar is enough to operate and control the gun. All he had to do is just lock the fire-control radar on the target and push the button to fire the gun; then the gun will always point to the target wherever it goes even if the ship is rolling or pitching due to big waves.

Unlike a similar armament aboard a World War II vintage ship, guns are manually loaded with ammunition then manually point, train and fire the gun to the target by a seven-man gun crew. The Oto Melara gun could fire about 30 times (or more) faster than manually loaded gun depending on the speed and teamwork of the gun crew. The real advantage here is the speed and accuracy of the Oto-Melara guns.

When one of the Otto-Melara guns encountered derangement one year after its acquisition, not a single person in the Philippine Navy knows how to put the gun back into operating condition. The Philippine Navy requested Australia to train PN personnel in conducting repair on such type of guns.

When Australia acceded, the PN sent personnel with a rating of gunnerís mate to undergo the training. However, these gunnerís mates were sent back to the Philippines because they donít know anything about electronics on which Oto Melara guns operates. So, the PN sent another batch of personnel with a rating of electronic technicians instead. The training lasted for two years then that will be the only time that the guns has been repaired.

Due to this incident, the PN was awakened and made aware on the state of readiness of our personnel towards modernization. The problem was
only about the repair of a gun commonly used around the world yet it gave an enormous headache to the PN. How much more if the problem was about missile system and electronic countermeasure equipment?

Sadly, for years after the publication of this paper, the PN continued to struggle to maintain these guns. So much so that, as per Timawans in the PN, the Navy didn't even bother to replenish its ammunition stocks till the closing years of the original Capability Upgrade Program. For years, the JCPVs sailed without full use of their primary armament. Arguably this was one of the reasons there was lack of videos of its main gun in operation, save for a very brief single-round salvo, posted on the PN Website early 2000s.

When the BRP Gregorio Del Pilar entered service in 2011 -- almost TWENTY YEARS since the JCPV joined the fleet -- it reportedly had a cycling problem that, yet again, was beyond the ability of PN personnel to troubleshoot and repair. This required the invitation of specialists from the manufacturer to sort out.

These are problems that, arguably, are known to both our friends and foes. The significance of the BRP Ramon Alcaraz's video of its main gun in action is, therefore, significant.

As were these two GUNNEXes in 2013 for BRP Gregorio Del Pilar and BRP Emilio Jacinto

http://adroth.ph/gunnex-for-oto-melara-ships/

These three developments imply that the PN has finally turned a corner with regards to its ability to operate this weapon. While this development remains under-appreciated by missile-obsessed military enthusiasts, the skills-mastery that this gun's operational status implies actually bodes well for the Navy's ability to operate modern systems.

From the Janes report about the RCWS that is expected to come with the Frigate Acquisition Project. While the actual identity of the 76mm gun has not yet been ascertained, the Oto Melara guns is a logical choice.

As confirmed by Janes, with their own independent fact checking.

Hyundai selects Turkish 30 mm naval gun system for Philippine Navy frigates

Ridzwan Rahmat - IHS Jane's Navy International
21 November 2017

Key Points
  • The Philippine Navyís new frigates will each feature a 30 mm gun system from Aselsan
  • The Turkish company is gaining a foothold in the region, and is also in talks with the Philippine government regarding further orders

The Philippine Navyís (PNís) new frigates will be equipped with the SMASH 30 mm remote controlled stabilised naval gun system from Turkish defence systems provider, Aselsan, an official from the company confirmed with Janeís on 20 November.

Each frigate will be equipped with one SMASH 30 mm system as a secondary weapon, and the system will be fully integrated with the platformís combat management system (CMS), said the official. Janeís understands that the weapon will be situated in the platformís stern section, facing its flight deck.

South Korean shipbuilder Hyundai Heavy Industries (HHI) won a contract in 2016 to supply the PN with two 2,600-tonne frigates that derive its design from the Republic of Korea Navyís (RoKNís) Incheon (FFX-I) class. Besides the 30 mm gun system, the warship is also expected to be equipped with an eight-cell vertical launching system (VLS) installed at the forward section, and a 76 mm naval gun.

According to specifications provided by Aselsan, the SMASH system is fitted with a 30 mm Mk 44 Bushmaster-II cannon that can fire up to 200 rounds/minute, and can be operated either via an operator console or in automatic tracking mode.

The system can be equipped with an electro-optic sight package containing a thermal camera, a video camera, and laser range finder, and also operate in surveillance mode to improve the platformís situational awareness. The turret can be fed via two separate ammunition stowage lines.

Speaking of the 76mm Primary Gun, which as per the PN specs required 120 rounds per Minute. The rate of Fire designed to counter anti-ship and Anti-air missile utilizing special ammunition's.

It means we are expecting some kind of Oto Melara DART/STRALES 76mm guided ammunition equivalent? Like The Strales 76mm system with DART guided ammunition which claim by  Oto Melara that it is the only weapon system in the world which can ensure high level performance (at a lower cost than dedicated anti-missile systems) in the engagement of manouevring supersonic missiles with high lateral g force

http://www.navyrecognition.com/index.php/news/defence-news/year-2014-news/april-2014-navy-naval-forces-maritime-industry-technology-security-global-news/1763-oto-melara-dartstrales-76mm-guided-ammunition-successfully-tested.html


Ammunition:
- HE (high explosive) - 6,296kg / Range 16km / effective range 8km (4km vs. air targets at elev. 85į)
- MOM (multi-role OTO munition)
- PFF (pre-formed fragmentation) - anti-missile ammunition
- SAPOM (semi-armored piercing OTO munition) - 6,35kg / Range 16km
- SAPOMER (semi-armored piercing OTO munition, extended range) - Range 20km
- DART (driven ammunition reduced time of flight) - sub-calibre guided ammunition against multiple targets (missiles and maneuvering targets at sea) 4,2kg in barrel / 3,5kg in flight / 660mm lenght / effective range >8km

No. If that was a requirement, they should have specifically mention:

"sub-calibre guided ammunition against multiple targets (missiles and maneuvering targets at sea) 4,2kg in barrel / 3,5kg in flight / 660mm lenght / effective range >8km" or something to that effect.

Otherwise "PFF (pre-formed fragmentation) - anti-missile ammunition" would met the requirements. Specifically, radio proximity fuses on these rounds would offer limited anti-missile capabilities. (e.g http://www.fuchs.co.za/products/naval.html). As long as the requirements are ambiguous, it can be read in various ways. Sometimes it can be advantageous to the government, sometimes to the supplier. Knowing when to be ambiguous and when to be specific, now that comes with experience.

DND opens bids for ammo of 2 PH Navy frigates
By Priam Nepomuceno  February 5, 2019, 1:25 pm

http://www.pna.gov.ph/articles/1061017?fbclid=IwAR3YUGjeCwShaFimj5OXg5N2QVA-Cpk-5LJlupS1eM7sr3Kgoq2Iwvi98VE

MANILA -- The Department of National Defense (DND) on Tuesday announced that it has begun the acquisition process for the ammunition needed to arm the 76-mm automatic main cannons and 30-mm secondary cannons of the two missile-equipped frigates, being constructed by South Korean shipbuilder Hyundai Heavy Industries (HHI).

An invitation to bid bulletin posted on the DND website indicated that PHP77,536,964 is the approved budget for the so-called Frigate Acquisition Project Lot 2C Sublot-1 or the acquisition for the 76-mm ammunition.

Meanwhile, the budget for the Frigate Acquisition Project Lot 2C Sublot-2 or the acquisition for the 30-mm ammunition, is placed at PHP100 million. Both will be sourced from the AFP Modernization Trust Fund.

Winning bidders are required to deliver the items within 240 calendar days upon receipt of the Notice to Proceed.

They must also have completed a similar project in the past 10 years, DND Bids and Awards Committee 1 chair, Assistant Secretary Manuel Felino V. Ramos, said in the bulletin.

The pre-bid conference for both projects will be held at the DND Bids and Awards Committee Conference Room, Basement, Left Wing, DND Building, Camp Aguinaldo, Quezon City at 10 a.m. on February 7.

The opening of the bids will be held at the same venue at 10 a.m. on February 21.

Earlier, Defense Secretary Delfin Lorenzana said that the two missile-armed frigates being constructed by HHI will be named BRP Antonio Luna and BRP Jose Rizal, two of the country's leading patriots.

He added that these names are fitting as they came from Filipino heroes.

Rizal is considered the country's national hero for his writing against the abuses committed by Spanish colonial authorities that inspired the Philippine Revolution.

Luna, meanwhile, is known for his staunch resistance against the Americans during the Philippine-American War.

The construction for the first missile-armed frigates is proceeding smoothly, Philippine Navy (PN) flag-officer-in-command Vice Admiral Robert Empedrad announced.

"(Construction for) our (first-missile) frigate is moving forward. It will arrive in February (or) March of 2020. All systems go and we should very happy. We should be happy for our country," he added.

The keel-laying for the first-missile-armed frigate took place in Ulsan, South Korea on October 16 last year, with steel-cutting for the second ship taking place last September 17.

HHI is expected to lay the keel for the second frigate by the first quarter of 2019.

The Philippines and HHI signed a PHP16-billion contract for two missile-armed frigates, with another PHP2 billion set aside for its weapon systems and munition. The projected delivery date for the first frigate is by 2020 and the second one, in 2021.

ďThe ceremony was conducted at the building dock number 6 of the Special and Naval Shipbuilding Division of HHI. Three blocks of the first PN frigate (with HHI Project Number 159) was installed on the dock,Ē Capt. Sergio Bartolome, the PN officer supervising the project, earlier said.

Keel-laying formally starts the ship's construction and is among the four highlights of a vessel life with the other three being the launch, commissioning and decommissioning.

The keel is also considered the backbone of any ship and breakage will result in the destruction and sinking of any water craft.

The steel-cutting for the first frigate took place last April. (PNA)

Spanish firm to supply 76mm ammo of Jose Rizal-class frigates
By Priam Nepomuceno  July 9, 2019, 1:55 pm Share

https://www.pna.gov.ph/articles/1074437

MANILA -- Spanish firm Expal Systems S.A. was named the winning supplier for the ammunition of the Oto Melara 76mm Rapid Gun arming the two Jose Rizal-class missile frigates now undergoing construction by South Korean shipbuilder Hyundai Heavy Industries.

"This is to inform you that the proposal of Expal Systems S.A .for the Frigate Acquisition Project Lot 2C Sublot-1 (76mm Ammunition) of the Philippine Navy, with a corresponding contract price in the amount of PHP63,389,708 is hereby accepted," Secretary Delfin Lorenzana said in the Notice of Award posted at the Department of National Defense website.

The project has an approved budget of PHP77,536,964. Aside from Expal Systems S.A., another firm, the Joint Venture of Elbit Systems Land and C41, Ltd. and IMI Systems Ltd, participated.

Earlier, the PN said the Oto Melara 76mm Rapid Gun was selected for the Jose Rizal-class frigates due to its high rate of fire and its ability to shoot down air targets like missiles.

"It (the gun) is capable of intercepting air targets to include missiles using special munitions," Navy spokesperson Captain Jonathan Zata quoting Offshore Combat Force head, Commodore Caesar Bernard Valencia, said.

Also, the Rapid Gun has a faster rate of fire, around 120 rounds per minute, compared to the current 76mm guns in the PN inventory which is only 80 rounds per minute.

These slower firing 76mm guns are fitted to the three Del Pilar-class offshore patrol vessels and three Jacinto-class patrol vessels.

And having the Super Rapid Gun fitted to BRP Jose Rizal (FF-150) and the BRP Antonio Luna (FF-151) is ideal as PN personnel are already trained in the maintenance of 76mm guns and compatible with the current munition inventory.

"(And the Super Rapid Gun is) within Approved Budget Contract for the (frigates' weapons systems)," Zata said. (PNA)
