Philippine Navy to Acquire Multi-Purpose Amphibian Aircraft under Horizon 2

As part of the Horizon 2 Priority Projects phase of the Revised AFP Modernization Program, the Department of National Defense (DND) and the Philippine Navy (PN) has started the bidding process for the acquisition of one (1) Multi-Purpose Amphibian Aircraft.

The Approved Budget for Contract (ABC) for this project is at Php1,333,333,333.33 (US$24.69 million based on US$1=Php54), and bidders are expected to deliver the aircraft within 730 days (2 years) from signing of Contract and receiving the Notice to Proceed (NTP).

The end user for the aircraft is the PN’s Naval Air Group (NAG), which currently operates the Beechcraft C-90 King Air & Britten-Norman BN-2 Islander surveillance and utility aircraft, and Cessna 172 Skyhawk trainer aircraft, aside from helicopters.

Requirements:

Based on the Bid Documents and Technical Specifications released by the DND for the project,  the aircraft can be considered as a brand new, Twin-Engine, multipurpose seaplane which is large enough to be capable of maritime surveillance, search & rescue, and Casualty Evacuation (CASEVAC) and Medical Evacuation (MEDEVAC).

The aircraft itself should have the following features:
- Twin Turbine Engined;
- Short Take-off and Landing (STOL) capable;
- With a cruising speed of at least 150 knots in full mission configuration;
- Payload of at least 1,500 kilograms in amphibian configuration;
- Endurance of at least 6 hours;
- Range of at least 900 nautical miles:
- Can take-off and land at Sea State 3 condition

For Maritime Surveillance, the aircraft is to be equipped with the following:

a. Electro-Optical / Infra-Red sensor – retractable to protect from sea landings, capable of multi-sensor imaging and lasing, and in high definition output.

b. Radar – Inverse Synthetic Aperture Radar (ISAR) using X-Band Active Electronically Scanned Array (AESA) technology capable of surface, air, and weather surveillance, with a maximum range of 120
nautical miles, and weighs not more than 40 kilograms.

c. Fitted for but not with Tactical Data Link 16, and permit 2-way exchange of tactical data with other TDL-equipped AFP units.

d. Identification Friend or Foe (IFF) / Selective Identification Feature (SIF)

e. Bubble-type Windows on both sides – to allow eyeball observation, including suitable use of DSLR camera and digital handheld video cameras.



As a Utility or Passenger Aircraft, the aircraft should have the following:

a. 4 Stretchers for MEDEVAC missions;

b. Seats for at least 19 passengers excluding the pilots:

c. Detachable Static Line for Para jump operations.

The supplier is also required to provide Integrated Logistics Support (ILS), including spares for 1200 hours of operation (an equivalent of 3 years worth of flying hours), Support Equipment and Structures including the tools, ground support equipment, and even the aircraft’s hangar that can accommodate 3 aircraft of the same model at any given time, and conversion training for pilots and ground crew.


PAF Search & Rescue Seaplanes Version 2?

Based on the requirements for the Philippine Navy’s Multi-Purpose Amphibian Aircraft, it is almost exactly the same as the requirements made by the Philippine Air Force a few years ago for their proposed Search & Rescue (SAR) Seaplane, which was later on shelved due to funding diverted to other requirements of the PAF during the Horizon 1 phase of the RAFPMP.

Even the budget for this PN project, which is Php1,333,333,333.33, is exactly the same budget allocated by the PAF for each seaplane.

Dimension size, range and endurance, engine requirements, and other aircraft feature requirements are also almost if not exactly the same as the PAF’s. The radar and EO/IR sensor requirements are also almost the same.

Previosuly, MaxDefense posted a blog entry regarding the PAF’s Search and Rescue Seaplane acquisition project, which can be accessed on the link below:

Details and Analysis of the PAF's Search and Rescue Seaplane Acquisition Project” – first posted on 16 November 2013.


You can see from the blog entry above and from the current requirements that there are not much differences from each other's requirements, both for the platform/aircraft and the onboard equipment. And it seems that it’s also pointing to the same aircraft as before, which MaxDefense believes is the Viking Air DHC-6 Twin Otter Guardian 400.

There isn’t too many available amphibian aircraft in the market that fits the requirements provided by the PN’s technical specifications. Other minor features indicated in the specs, like a need for a lavatory, makes it more specifically pointed at the Twin Otter Guardian 400.

It has all the bells and whistles that the Philippine Navy is looking for based on the aircraft specs it made publicly available.

The aircraft itself is powered by 2 turbine engines, has a surveillance range of 970 nautical miles (vs 900 nautical miles), and surveillance time on station of 7 hours (vs 6 hours).  And aside from having floats to make it amphibian, the landing gear can be configured also to use standard wheels.

It has a 19-passenger seating (meets requirements), a lavatory, and can be configured to carry up to 8 stretchers (vs 4 stretchers).

It is equipped with a CarteNav AIMS-ISR Data Management System that controls and integrates the mission sensors, which includes the Selex Seaspray 500E AESA surface search radar, and a retractable EO/IR sensor using either the FLIR PolyTech UltraForce 350 or L3 Wescam MX-15HDi EO/IR sensor equipment. An Automatic Identification System (AIS) can also be installed as an option (required by PN), and several other features.

The only problem we see here is the aircraft being from Canada, which could be an issue after what happened to the G2G deal between the DND and Canadian Commercial Corporation. The export license may be an issue, considering that the aircraft is military in nature although it is obviously not armed and cannot be used to kill people.

But if this pushes through without too much drama, this opens up the window again for defense acquisitions from Canada, although probably limited only to unarmed systems.



Impact on the Naval Air Group:

Once this aircraft comes into service, this would effectively become the Naval Air Group’s most capable maritime patrol aircraft, considering that the plan to upgrade their existing Beechcraft C-90 King Air fleet by installing surveillance equipment is has not moved beyond the planning stage yet as of this writing, while MaxDefense believes that there is only 1 of their BN-2 Islander aircraft that was upgraded with a limited maritime surveillance capability.

It would also lay the groundwork for the acquisition of more Amphibian Aircraft for the PN-NAG, considering that despite only 1 was requested in this Horizon 2 phase, originally the PN-NAG was requesting for at least 3 aircraft worth Php4 billion (still based on a budget of 1 aircraft for Php1.33 billion). The PN-NAG is targeting to have 6 aircraft by the end of Horizon 3 phase, which means up to 5 more will be acquired.

Together with the Beechcraft C-90, these will form the Philippine Navy’s Maritime Patrol Aircraft fleet covering short-medium range requirements of the AFP, while the Philippine Air Force will cover the long range requirement using their still pending Long Range Patrol Aircraft and their upcoming Hermes 900 unmanned aerial systems.

The disadvantage of these air assets are their lack of capability in anti-submarine warfare (ASW), as well as munitions delivery capability. It is expected that these assets will act as eyes and ears for the fleet, as well as part of the overall AFP C4ISTAR system interconnecting all AFP units into a more cohesive fighting force.


Procurement and Bidding:

The bid opening is currently scheduled on 16 October 2018, although this could change depending on request by potential bidders for time extension or further clarifications. But due to the requirements leading too much for a specific product, MaxDefense doesn’t expect a lot of drama coming out from this project.

Viking Air is apparently represented in the Philippines by Asian Aerospace Corporation (which requested for the bid documents based on PhilGEPS page of the project), although previously, Viking Air appears to have made their own representation during the PAF SAR Seaplane Acquisition Project.
With the project still in the pre-bidding stage, MaxDefense expects a lot of updates coming out in the next several weeks leading up to an award. Hopefully, the DND would at least release the Notice of Award to the lowest calculated bidder before the end of the year.

UPDATES:

20 February 2019:

MaxDefense learned that the Public Bidding for the Multi-Purpose Amphibian Aircraft acquisition for the Philippine Navy FAILED. This is due to no bidders submitted a bid when it closed last October 2018.

The worrying part is that the Department of National Defense (DNd), which is undertaking the bidding process on behalf of the Philippine Navy, has not reopened the project for another re-bidding.

Re-Bidding is expected to happen since the country's procurement laws under RA9184 only allows going into negotiated procurement after the DND fails again in another public bidding attempt.

The decision to go for public bidding is actually a funny decision by the DND, since it is very clear that the Philippine Navy is after a specific aircraft, which is the de Havilland Canada DHC-6 Twin Otter from Viking Air. They are being represented in the Philippines by only a single company.

Should they have just went for a negotiated mode of procurement, this project should already be rolling by now.


Just for the sake of discussion, is the Philippine Navy really urgently needing to acquire this, considering only a single aircraft is involved? 

While it is highly possible that this is a prelude to the acquisition of several more (as the PN is looking at having at least 6 of them for a squadron) and that this unit is to prepare them for it, there are several projects in the Philippine Navy that MaxDefense and several of it's contributors believe to be underfunded. 

Among them are the following:
1. Del Pilar-class Frigate Upgrade Project - MaxDefense was told by people involved that the budget is too low that even the cheapest product being offered many not meet the requirements!!

2. Offshore Patrol Vessel acquisition - the mission modules needed for other important missions like minehunting may not be funded as the project's budget is already too tight for additional items. Also, the additional budget may allow the PN to specify a better sensor suite (i.e. a 3D radar instead of 2D) for all 6 ships.

3. Frigate acquisition (Horizon 1 Jose Rizal-class) - is the PN not considering the installation of 2 units of 30mm machine gun system instead of just having 1 unit per ship? Normally 1 gun system covers 180 degrees of the ship, and 2 are needed to cover most, if not all sides of the ship from surface threats like small suicide boats. Why not install 1 gun system each at port and starboard side, just like what they did on the BRP Ramon Alcaraz?

These are just questions that we hope the Philippine Navy can see, as we believe these proposals could be also in the minds of some of their officials.

MaxDefense will provide more updates on this Multi-Purpose Amphibian Aircraft acquisition project as more information comes in.

  1. well atleast it specifically states fitted for but not with tactical data link 16

  2. The Link 16 data link is only "awarded" to trusted allies and cannot just be bought. It came from NATO and if the Philippines insist on "friend to all enemy to none" we will never get it. We might as well get a proprietary data link like Thailands T-1 DL made by Saab.

    Few know but that AESA radar or any AESA radar for that matter may cost as much as that aircraft the NAG wants.

  3. That LINK 16 .., make me sad about the frigate from HHI.,

  4. I HOPE OUR NEXT 2 FRIGATES WILL BE NAMED AFTER GENERAL ANTONIO LUNA AND LAPU LAPU

    BRP ANTONIO LUNA
    BRP LAPU LAPU

    FIT FOR DEL PILAR CLASS.
    And 2 more future frigates will named CAVITE and LEYTE . Cavite bcoz many battle against spain wins in that place and LEYTE bcoz the legendary Naval war happens there.
    BRP CAVITE
    BRP LEYTE
    And for incoming Corvettes will name after RAMON MAGSAYSAY bcoz he is the president who first modernized AFP. GENERAL PIO DEL PILAR.
