The absence of enough information regarding the Philippine Navy's Strategic Sealift Vessel (SSV) has left the public blind on what we can expect on the ship's capabilities, features and aesthetics. But the recently released Supplemental Bid Bulletin (SBB) # 4 by the Department of National Defense (DND) has brought in enough relevant information on the project, as well as some hints of future procurement plans of the Armed Forces of the Philippines (AFP), to the point that we can now somehow see a clearer picture of what the SSV really is.
Based on the Supplemental Bid Bulletin # 4 for the SSV project, here are the basic information of the ship's specification based on MaxDefense' interpretation (a copy of the SBB can obtained here: http://www.dnd.gov.ph/DNDWEBPAGE_files/BAC/2013/SBB/august/SBB-AFP-PN-SSV-13-04.pdf)
Type: Landing Platform Dock (LPD)
Displacement: approximately 7,300 tons full load, subject to shipbuilder's design
Besides the basic information of the ship, there are also more information that MaxDefense finds interesting to discuss with, and here are the following points:
1. Presence of floodable wells and helicopter deck with hangar.
These features, plus the general information of the ship's details listed above, confirms that the SSV is indeed a Landing Platform Dock (LPD), a small one though as compared to typical Western designs. Larsen and Toubro's query even included a clarification on the ship's type being labelled as an SSV when in fact the ship is an LPD. The dimensions indicate that it has similar dimensions as the Indonesian Navy's Makassar-class LPD, and surprisingly has almost the same details as the SSV offer made by PT PAL. But unlike the Makassar-class, the SSV will be smaller, lighter and may be simpler to reduce costs.
2. Use of Mild Steel per ASTM A131 for the hull.
A query by Stone of David highlighted this and request considering the use of a more sturdier material for the hull, although the PN insisted on mild steel. Actually mild steel can be considered an excellent ship hull material due to its high strength, sufficient ductility and low cost. It retains some strength after yielding and before failure, which is a good characteristic for ship hulls. It is also lighter, giving the ship a better power to weight ratio for efficiency, while retaining the required strength as compared to other steel hull materials.
3. Inclusion of 2 Landing Crafts Mechanized/Utility (LCM/LCU) and 2 Rigid Hull Inflatable Boats (RHIB) per ship.
The SSV program already included the provision of 2 steel-hulled LCU or LCM as well as 2 RHIBs that will be delivered together with each ship. This was unexpected although it is a welcome addition since it was assumed earlier that these boats will be bid-out separately and will require a different budget and program. Although this would also mean that the cost for these boats will be deducted from the budget allocated for the SSVs.
4. Boat davit capacity of 15 tons while RHIB at full capacity is only around 4 tons.
Several bidders like Stone of David, Larsen and Toubro, and Propmech highlighted the issue of having a boat davit with load capacity of 15 tons that will be holding the RHIB, probably because they believe this an over-design that relates to higher costs. Although the PN intends to place RHIBs on these davits, it is expected that the PN may also opt to fit the heavier LCVP in its place when necessary. Actually Stone of David's query already indicated the possibility of using the davits for LCVPs. The LCVP usually has an empty weight of around 9 to 9.5 tons and will require a higher capacity davit, on this case the PN insisted on a 15-ton capacity davit.
5. Payload capacity of deck turntables at 25 tons.
The turntable is required to be able to handle a 25-ton payload of around 7 meters long, which are probably armored vehicles from either the Philippine Marines (PMC) or Philippine Army (PA). Except for the PMC's few LVTH-6, the heaviest armored vehicles in both the PA (ACV-300) and PMC (V-300) only weigh around 14 tons. MaxDefense does not expect the incoming AAVs to use the turntables so it means that the SSV is built to accomodate larger and heavier armored vehicles should the PA or PMC acquire them in the future.
6. Helicopter landing deck and hangar capacity requirement.
There is a requirement for the ship to have a helicopter landing deck for 2 helicopters, and a hangar capacity for 1 helicopter. The replies provided by the DND/PN indicated that the helicopters are 10-ton types, with a specific mention of Sikorsky's Black Hawk helicopter. Although the Philippine Air Force (PAF) currently has a single S-70A Black Hawk in its fleet (Presidential Wing asset), it is expected that the ship will accommodate navalized PN helicopters more than standard PAF ones. MaxDefense believes that the PN may have plans to purchase Black Hawks in the future as part of its Desired Force Mix multi-purpose helicopter requirement, and the PAF may also do the same.
7. Replenishment as Sea (RAS) capable.
The SSV will be RAS capable, with both port and starboard sides having RAS stations for easy replenishment. The PN's Gregorio del Pilar-class frigates are capable of RAS, but this capability is currently not available with the PN, although there are some indications that the PN is trying to acquire such capability, possibly by taking replenishment from allied naval vessels in the absence of PN replenishment vessels. There is also a possibility of the PN acquiring replenishment vessels in the future, as indicated in its Desired Force Mix white paper.
8. Weapons and sensors systems costs are separate from the ship's budget.
The SSB mentioned that the weapons and sensors systems will be "owner supplied", meaning it will be provided by the PN separately. This removes the cost of these systems from the SSV's budget, and good thing considering that these systems may cost as much as the budget allocated by the DND. With these separated, shipbuilders would now have more room to provide a better offer, and is beneficial to both the bidder and the end user.
9. Types of weapons and sensors for the ship.
Sensor types mentioned in the SSB include a surveillance radar, an air search radar, electro-optical fire control system for the secondary guns, a Combat Management System, and an Electronic Warfare (EW) suite. The presence of an option to place an air search radar feature will enable the ship to detect and track airborne threats like aircraft and cruise missiles. The PN may employ similar radar systems that they intend to install on other future PN combat vessels like the new frigate. The EW suite is an added feature that would be beneficial as it gives an added defensive feature for the ship from OPFOR attacks. As for the weapons, the SBB mentioned the presence of 2 units 30mm guns, both remotely operated with electro-optical fire control system (EO-FCS). Although not mentioned, it may be safe to assume the presence of a larger primary weapon, probably a gun system with a higher caliber the secondary guns, somewhere between 40mm to 127mm. Also like other PN vessels, it is expected to have manually-operated 12.7mm machine guns for self-defense against small boats and minor threats. No mention was made regarding missile systems or anti-missile CIWS though.
10. The SSV are configured as possible flagships.
The SBB confirms the earlier press releases that the SSV will also serve as flagships and mobile government centers aside from being amphibious transport vessels. The supplemental bulletin acknowledge the presence of a Presidential Room as well as a War Room, which are instrumental for government functions including the presence of the President of the Philippines in cases of emergencies and needs that require him and other key government officials to be on the ship.
Besides the above-mentioned details, some other information on the ship includes:
- the ships are designed to accommodate future AAVs (probably based on the AAV-7A1)
- availability of water desalination system capable of producing 25,000 liters per day;
- provision for bow thrusters, possibly for installation in the future;
- LCU / LCM will be steel-hulled, empty weight of 70 tons, load capacity of 18 tons or 80 troops, armed with 2 x 50 caliber machine guns;
- SSV delivery will be on Manila's South Harbor Pier 13
The scheduled submission and opening of bids is on August 29, 2013, although there is still a possibility of moving it to a latter date similar to what happened to other DND projects. Until then, let us see who among the potential bidders could step forward and offer their services to the DND.
===================================
Updates:
August 29, 2013:
Of the 9 potential contenders for the SSV project, only 2 submitted their bids: PT PAL Indonesia (builder of Banjarsamin-class) and Daewoo-Daesun of South Korea (builder of Makassar-class). But after further examination, the DND only qualified the bid of PT PAL, while Daewoo-Daesun was disqualified. It is still a hanging project as PT PAL needs to pass the post bid qualifications, which may start soon.
More of the news here and here.

February 3, 2014:
The Philippine Navy has already provided the Notice of Award (NOA) for the SSV project to Indonesia's PT PAL after passing the post-bid qualifications and inspections. PT PAL itself confirmed receiving the NOA late last month, and is expecting the signing of contract to follow soon following these developments.
