Helicopters as Alternative Way to Supply PH Outposts in Kalayaan Islands

The difficulty encountered by the Department of National Defense (DND) and Armed Forces of the Philippines (AFP) to relieve and replace its troops, and sending provision and supplies to its troops stationed in the BRP Sierra Madre at the Ayungin Shoal (Second Thomas Shoal) outpost was recently highlighted. A civilian ship of the government, BRP Fort San Antonio (AM-700) was sent to Ayungin Shoal for a second attempt to resupply and relieve troops at the AFP's outpost there when China Coast Guard vessels attempted to block the Philippine vessel. This aggression was captured on film by local and foreign media invited to the voyage, making the Chinese aggression in the Kalayaan Group of Islands (KIG) public. It was a good move by the Philippine government as part of its efforts to show to the world what is exactly happening on this side of the globe. 

With skill and some luck, the second attempt to reach the outpost was successful, but until when can the AFP do the same to freely access a part of Philippine territory and EEZ. The Philippine government must always consider changes in the way the Chinese until try to control the area. It is expected that the China Coast Guard will make adjustments to their naval blockade and make sure that a repeat of the successful passage of a Philippine vessel will be harder or impossible next time.

So far, the Chinese are unable to stop aerial resupply missions, wherein the Philippine Navy (PN) previously use their BN-2 Islander light utility aircraft and flying low over the BRP Sierra Madre and drop supplies. Stopping them can only be done by either forcing them away using fighter aircraft, which is already an aggressive move but can still be disregarded by AFP aircraft. Other ways to stop aircraft attempting to supply the outposts is by radar-locking the aircraft, which is already a serious threat from the aggressor being a signal of a probable missile launch, or by shooting down the PN aircraft. Although the Chinese may not do the last 2 possibilities, it can do the first example but the AFP aircraft can always disregard them.

With this, MaxDefense suggests the use of medium or heavy-lift helicopters, which can operate from naval or civilian ships several miles away from the Chinese blockade. These helicopters have the endurance, size, and payload capacity to carry men and supplies from a distance, and can fly over the Chinese naval blockade. Supplies can be dropped on the deck of BRP Sierra Madre and on allocated spaces provided on far-flung outposts in the KIG in a similar way as a vertical replenishment (VERTREP) usually done in naval operations.


Vertical Replenishment:
Also known as VERTREP, this is a method of dropping supplies to ships or outposts similar to the BRP Sierra Madre. Supplies can be carried underneath helicopters using specialized slings or cargo nets, and are delivered by hovering the helicopter over the drop area and manually releasing the load from below. The Philippine Navy is currently learning this supply process using their newly-acquired AW109 Power helicopters as part of their skills and capability improvement.

Suggested Helicopters:
So far, only the Philippine Navy's Gregorio del Pilar-class frigates have the capacity to carry helicopters capable enough to do major VERTREP missions, and are only equipped with small helicopters like the AW109 Power which are not really designed for this capability. But these frigates' flight decks are capable of accepting 10-ton class helicopters, there are very few helicopters that can be suggested for this requirement.

The most obvious helicopter is the Sikorsky MH-60S "Knighthawk", which is the primary VERTREP helicopter of the US Navy. It was designed to do these missions, and can also be a viable candidate for the PN's requirement for transport helicopters for its upcoming Strategic Sealift Vessels (SSV). The PN could acquire 4 units, 2 assigned for each of the future SSV, and can be temporarily assigned to other PN ships for duties such as supply runs.

But buying new helicopters means that it will take some years before the first helicopter becomes available, so MaxDefense also suggests the acquisition of EDA helicopters in the meanwhile either by grant or reduced price purchase. MaxDefense suggests the Boeing Vertol CH-46E Sea Knight helicopters that are being replaced in the US Marine Corps, and are readily available for transfer to allies like the Philippines. Sea Knights were previously used by the US Navy for VERTREP missions until they were replaced by the MH-60S. These helicopters can be carried by the PN frigate's flight deck and are capable of VERTREP operations. Reportedly the US has been offering the CH-46 to friendly nations, and can be requested by the DND as part of the US' defense assistance to the Philippines.

Aside from ship-based helicopters, the AFP could also consider acquiring larger transport helicopters that can be deployed from Palawan to supply its outposts in the KIG, and at the same time be used for other missions like humanitarian assistance and disaster relief (HADR) and troop transport. 



Other Possible Helicopter Suggestions:
The DND has been looking at acquiring larger helicopters than its current assets, but has always given priority to replace its ageing UH-1H fleet while also having consistent budgetary issues that has been plaguing the Philippine armed forces for several decades now. But with the move to improve the military's transport and HADR capability may have opened the possibility to acquire them due to their size, range and payload in carrying supplies. This was suggested earlier by MaxDefense in an earlier blog entry, and it appears that the DND has shown interest on acquiring such assets and has been looking at this capability that may be included in its future defense procurement projects. 

Coming from the mainland Palawan which is more than 100 miles from the outposts, they could store the supplies inside the helicopters, and deliver them by hovering low and dropping them on specialized platforms installed on the ship deck which will safely break the fall of the supply containers. 

For heavy-lift helicopters, MaxDefense suggestions include the CH-53 Super Stallion/Sea Stallion and the CH-47 Chinook, both of which are available for Excess Defense Articles (EDA) transfer from the US government. The DND may even opt to buy a couple of new Boeing CH-47F Chinooks or the Sikorsky CH-53K Super Stallions if budget permits, although getting EDA would be an easier route due to cost considerations.

Surplus CH-53D Sea Stallions can be obtained from the US military stocks, after refurbishing that will probably be shouldered by the Philippine government.

Another alternative are the smaller but still capable medium-lift helicopters, which are also currently not available in the PAF or AFP's inventory. MaxDefense suggests the Eurocopter's EC725 Super Cougar, or AgustaWestland's AW101. These helicopters are reportedly cheaper to acquire, operate and maintain as compared to larger helicopters like the Super Stallion.

Another worth considering for the medium helicopter is the AgustaWestland AW101, the example above being operated by the Royal Air Force.

Some issues that hinders the acquisition of heavy and medium-lift helicopters for the AFP are mostly on the costs of procurement, operation, and maintenance. Operating a squadron may indeed be cost prohibitive to the AFP, but operating a small fleet of at least 3 or 4 heavy-lift helicopters might be sufficient for the basic requirements of the AFP and in supporting resupply missions. Aside from this, the helicopters can be used for combat and peacetime search and rescue, air assault missions, and transport requirements to areas without airfields. 

These large helicopters may not need to be operated at the same tempo as the smaller combat utility helicopters of the PAF. The availability of other rotary assets like the UH-1H and W-3A, and Bell 412 with the PAF means that the AFP has a lot of helicopter options to use in case the heavy lift helicopters are considered too much for a certain mission. This is the same concept to the reason why the Philippine Air Force (PAF) maintains and procures different transport aircraft sizes like the C-130, C-295 and NC-212. 




Preparation of BRP Sierra Madre for VERTREP:
For the BRP Sierra Madre, it would also be best if the AFP can make structural modifications on the ship's deck to make it suitable for dropping supplies carried underneath the helicopter, and not necessarily for the helicopter to land. Recent photos of the outpost shows massive degradation of the steel deck that may not be able to carry loads brought upon by a heavy-lift helicopter. 

Structural strengthening will improve the ship deck's capability to accept heavy load of supplies without the risk of giving way due to weight. This may include works that may affect the so-called "status quo" of not building structures on the disputed territories, although the works can be made inside the ship without being noticed by Chinese or other foreign surveillance aircraft, ships or satellites. The only concern on this is bringing in the construction materials needed, which might be done by another supply run via ships similar to the usual procedure the AFP does its supply missions.

Aside for preparation for VERTREP, the ship is in dire need for repair works and improvement of facilities. The entire ship is literally falling apart and becoming unsafe for those Marines stationed there. This is another consideration why the AFP and DND must think of ways to physically improve the outpost and improve the living conditions there. 

Other outposts in the KIG, like those on Patag, Panata, Kota, Lawak, Parola, and Pag-asa islands, at Rizal and Balagtas reefs must also be improved, although this may have serious implications that will give other claimants their own reasons to do the same for their occupied areas. A simple provision of supply dropping point  by helicopters can easily be prepared without doing major construction works.

Other outposts like those in Patag Island have enough space for helicopters to land. Accessing the island from to bring supplies from ships requires the use of rubber boats to avoid stranding the supply ships.

UPDATES:
===========
July 20, 2015:
News reports surfaced on the plans to structurally repair and improve the BRP Sierra Madre in Ayungin Shoal (Second Thomas Shoal), which includes preparing a helicopter landing deck on the ship. It is still unclear how the AFP or Philippine Navy intends to do that reinforcement for the ship (which is still considered a commissioned warship of the Philippine Navy), but it would definitely be enought to accomodate existing PAF and PN helicopter assets.

MaxDefense suggests that they consider increasing the load carrying capacity of the helicopter landing deck, including installation of proper lighting and safety features to enable nighttime and poor weather condition use if necessary. 

Although this project for the ship should have been kept under dark to the media due to its sensitivity, everything is already out so the best they can do is make sure to do the upgrades, and do it fast without hesitation or budget deprivation.

A Direct to the Point Analysis from Jose Antonio Custodio: How the PH handled territorial disputes over the years

Here's a very good analysis coming from a well known defense analyst. This was posted here due to its significance to Philippine defense policy. To Prof. Jose Antonio A. Custodio, good work! This was posted at Interaksyon.com as a special article, posted in its entirety here @ MaxDefense.

LOSING GROUND: How PH has handled Sabah, West Philippine Sea disputes over the years

Original here: http://www.interaksyon.com/article/61320/losing-ground--how-ph-has-handled-sabah-west-philippine-sea-disputes-over-the-years?fb_comment_id=fbc_532615796784413_5656774_532759206770072

By Jose Antonio A. Custodio, Special to Interaksyon.com

Much has been made by pundits and opinion makers in media regarding the alleged lack of direction and purpose of the current administration regarding foreign policy especially on the matter of territorial disputes. However, an observation of the manner in which the Philippines has handled its territorial claims reveals a systemic and institutional approach that transcends administrations and is consistent in its approach to the issue throughout the years. That approach is best described by being characterized as vacillation and lacking resolve despite the occasional assertive rhetoric.

US rejects military option in Sabah, Marcos blinks

The first major engagement of the Philippines in territorial disputes was the Sabah crisis that began in the 1960s. Much has been written about the validity of the Philippine claim and in the past several months, due to the actions of the Royal Sultanate Army at Sabah, this has once again been reiterated in media. Hence, the validity of the Philippine claim to Sabah will not be discussed here, but rather the actions that the Philippine government did in the 1960s to advance that claim.

Aside from the usual diplomatic and legal campaign that the Philippines did, by the late 1960s during the term of President Ferdinand Marcos, a military option was considered and this frightened the Malaysians and became a cause of concern for the British. The strong British support of Malaysia and the lack of United States support for the Philippines plus the controversy over the "Jabidah Massacre" put an end to that military option. The real objective behind this plan of Marcos, code named "Operation Merdeka," remains unclear and despite the stated desire to reclaim Sabah, there may also have been another one which was probably to serve to deflect criticisms to his administration.

Although the Philippines had attempted to use a military option as the primarymeans to resolve in its favor a territorial dispute it also revealed a weakness in Manila's approach to disputes when it tried to get American support. Naturally, the Americans were not willing to support the Philippines at the risk of jeopardizing their relations with the British. Furthermore, the Americans were neck deep in the quagmire of the Vietnam War and needed all the international support for that involvement of theirs and they did not need another conflict to distract them. Failing to obtain American support and not willing to engage British forces, not to mention the internal political problems already affecting the Philippines, Marcos blinked and backed off.

No credible air defense to defend Spratlys

During the mid 1970s the Marcos administration pursued another territorial claim of the Philippines, this time at the Spratlys Islands. Issuing several presidential decrees creating the Kalayaan Island Group municipality and the delineation of the country's Exclusive Economic Zone, the Marcos administration then began to improve the defenses of the KIG. Garrisons were established in a number of islands of the KIG while at the same time installations were improved such as the building of the Rancudo airstrip at Pagasa Island. The Philippine Air Force was strengthened by the acquisition of the F-8 Crusader which was deployed for the defense of the West Philippine Sea. As long as the PAF had those aircraft in the area, the Philippines had undisputed air supremacy in the WPS. However the decommissioning of the F-8s in 1988 and the F-5s in 2004 removed any credible Philippine air defense in the WPS leaving that role to aircraft not configured for such tasks as the diminutive S211 trainer and the slow and vulnerable propeller driven OV-10. Such inadequate aircraft as the PAF uses now will be knocked out of the skies in the event of a skirmish between forces in the KIG.

The Spratly Island chain

Still for some time, the Philippines was in a position of strength in the KIG and together with the powerful American presence in Subic and Clark, no country dared to venture close to the Philippines. However, several developments upset that. The first was that beginning with the Marcos administration, the country experienced heightened social justice and economic problems that saw the defense establishment prioritize internal security operations above everything else. This effectively scuttled the plan of Ferdinand Marcos to modernize the AFP in the early 1980s when there were plans to purchase more jetfighters such as the F-5E to replace the F-5A as well as order additional materiel and equipment through the Excess Defense Articles and Foreign Military Sales Programs of the United States. One by one, AFP external defense capabilities disappeared as a result of the neglect and the focus on internal security.

Following the fall of the Marcos administration, another development that created a problem for the territorial ambitions of the Philippines was the non-renewal of the Philippines-United States Military Bases Agreement in 1991 and the closure of the bases in 1992. Three years after the departure of the Americans from Subic and Clark, the Chinese moved into the KIG in force and began to press harder on their claim over the Scarborough Shoal aka Bajo de Masinloc.

In 1995, the Chinese constructed military installations in the Mischief Reef some 150 miles away from Palawan Island. The Philippine government was caught flatfooted by this Chinese action and was unable to deal with the intrusion in a manner favorable to the Philippines. The response of Manila was to announce that diplomacy would be resorted to and that this would be considered as the first line of defense. To make matters worse, the initial AFP Modernization Plan died a stillborn death due to the Financial Crisis of 1997 and the lack of seriousness of the Philippine government to pursue defense modernization as it flip flopped on whether to continue programs or not.

Faced with this Chinese challenge, Manila chose to rely instead on the US security umbrella provided by the Philippines-United States Mutual Defense Treaty. At this point, the US was expressing concern at what it perceived as a rising regional hegemon in the form of China. This dovetailed with Manila’s desire to revive the good old days of US military assistance and the end result was the drafting of the Visiting Forces Agreement and the passing of it in the Philippine Senate during 1999. Both sides raised the Chinese threat to win support for the agreement and there was this perception in Manila that equipment and funding would pour into the AFP. This however was not to happen because of two reasons. First, on 11 September 2001 the terrorist attacks distracted the Americans from their focus on China. Second, despite the elevation of the Philippines as a Non NATO Major Ally in 2003, no flood of support went the way of the AFP from US sources as Washington was not in an economic position to provide such substantial freebies and it concentrated on assisting Manila in its internal operations against terrorist groups.

Overly reliant on the United States

For years, the US had carefully created a multilateral framework of engagement in the Asia Pacific region to contain China’s rising ambitions. This was temporarily abandoned in favor of bilateral arrangements between the US and other countries to quickly conduct operations in the War on Terrorism. Furthermore, concerns on China took second place in Manila as it joined the anti-terrorism bandwagon to the point that the Philippine defense establishment agreed to prioritize internal defense and scrapped remaining external defense capabilities such as operating fighter jets on the recommendation of American and Filipino defense officials. Thus instead of weaning away itself from the security umbrella of the United States, the Philippine government became more and more reliant on American protection on almost everything concerning defense matters. To emphasize that, whereas before the Philippine military and police undertook it upon themselves to handle internal security threats leaving the US to take care of external matters, following the 9-11 terrorist attacks of 2001, American military personnel began to operate against the Abu Sayyaf Group. Despite denials by the Americans of conducting operations other than the stated civil military activities that their personnel are doing in Mindanao, there is enough evidence to show that American activities are not limited to peaceful and developmental types but also those with a purely military operational support and intelligence application.

 The cumulative effect of this is that it has made the Philippine government overly reliant on US defense guarantees and totally focused on internal security operations. Manila dragged its feet on modernizing the AFP for external defense and made diplomacy its only option in matters concerning territorial defense. There has been little or no progress in defense upgrade programs in the AFP and there still exists service related rivalries within the military pertaining to prioritizing internal security or external defense. In the case of the US defense alliance, the relationship borders on the level of naivety for the Philippines as it tries to push the Americans to declare guarantees of military response or provide materiel and equipment support at the same level as the Cold War era and when this does not happen, Filipino leaders express childish dismay. Some of these leaders who express dismay then play with the idea of having an alignment with Beijing at the expense of the US defense relationship, with the rationale that China after all is growing in capabilities and strength.

US interest not same as PH interest

There is a failure to realize that American national interests do not necessarily jive with Philippine interests even though both have concerns with China’s rising hegemonism due to time and space factors. The American perception on China considers the Chinese as a near future threat that needs to be constrained to make it act in a responsible manner in the present. The Philippines however is immediately affected by Chinese actions at the West Philippine Sea, and yet despite this, the Philippines has stuck to taking actions of the usual diplomatic protest and legal process of which part of it is to make its allies and regional partners carry the burden of territorial defense of Philippine interests in the WPS. In jest, it may be said that the Philippines is prepared to defend the WPS to the last American soldier, plane, or ship which is something that the US will not oblige the Philippine government with.

‘Bleed for its claims’

Perhaps it should not be a surprise as to why the Philippines appears to be sacrificing one piece after another of its territory to foreign powers. It may be partly explained by the internal focus that has affected the country since the 1970s. There have been two generations of Filipinos since then who have been fed a daily uninterrupted dose of internal political instability, social divisions, and rampant insurgencies that makes anything external seem to be an alien concept. Furthermore, since the Philippine government is willing to discuss with rebel groups issues such as official recognition of what constitutes rebel held territory in the country’s metropolitan areas during peace negotiations, it then does not come as a surprise that it feels no sense of urgency or grave loss should portions of our EEZ (exclusive economic zone), islets, and reefs come under foreign control.

Although the Philippines has sought to legally challenge China’s 9-dash-line declaration over the whole South China Sea inclusive of the WPS at an international arbitration body, it does not seem to be as assertive in attempts to physically protect Philippine territorial interests in the area. Chinese poachers routinely operate in the WPS while smugglers come in and out of Philippine waters with impunity as can be seen in the case of the F/B Min Long Yu which ran aground at Tubbataha Reef last April 8, 2013. Had it not run aground, no one would have known it was even in the area. Worse, is that the Philippines has not physically reasserted its claim to the Scarborough Shoal and it naively appears to assume that if it wins the arbitration case, China will meekly withdraw. However what will happen if the Chinese ignore the verdict of the international body and continue to not only hold on Philippine maritime territory but grab an additional piece just to thumb their noses at world opinion and “teach Manila a lesson” as the nationalistic Chinese bloggers have been demanding for? One must remember that international condemnation of China’s control of Tibet has not persuaded Beijing to withdraw but instead the Chinese have adopted measures to Sinicize Tibet.

The problem with the current Philippine strategy on territorial disputes is that Philippine officials actually believe that irrefutable legal rights, confidence building measures, and favorable international opinion will do the trick and win the day for the country. What they cannot seem to understand is that in the history of the world, all territorial claims are determined by the capacity of the claimant to bleed for its claim, physically occupy its claim, and not just blabber about it in endless track 1 and track 2 diplomatic activities.

BRP Gregorio del Pilar (PF-15) and other ships are not enough if the government's mindset does not change.

The country’s record in physically defending its territorial claims presents a very dismal picture. It has always backtracked and refused to reassert control when countries like Malaysia, Vietnam, and China occupied Philippine claimed territory. There appears to be a clear lack of willingness to commit to a military option on the assumption that the Philippine military is too weak to do anything and that conflict should be avoided at all times. If it was merely a question of military capability, then the Philippines should have been able to launch an operation against the Vietnamese in the 1970s to reclaim an islet at the Kalayaan Island Group that they seized because the Philippine military had a better power projection capability than Vietnam at that time. Instead the Philippines did nothing while that islet was eventually absorbed into other territories at the South China Sea claimed by Vietnam. Hence, even if the Philippine military does modernize in the future, it is not a guarantee that the government will act more resolutely and it may instead respond in the same weak kneed manner. This is brought about not because of the lack of bravery of the military, but more of indifference and failure to understand the nature of territorial disputes within the Philippine government.
