Philippine Air Force

The Early Years and World War II

The forerunners of the Philippine Air Force was the Philippine Militia, otherwise known as Philippine National Guard (PNG). On March 17, 1917 Senate President Manuel L. Quezon enacted a bill (Militia Act 2715) for the creation of the Philippine Militia. It was enacted in anticipation that there would be an outbreak of hostilities between United States and Germany.^[2]

By the end of the First World War, the US Army and Navy began selling aircraft and equipment to the Philippine Militia Commission. The Commission then hired the services of the Curtiss School of Aviation to provide flight training to 33 students at a local base in Parañaque.

The early aviation unit was, however, still lacking enough knowledge and equipment to be considered as an air force and was then limited only to air transport duties.^[2] On January 2, 1935, Philippine Military Aviation was activated when the 10th Congress passed Commonwealth Act 1494 that provided for the organization of the Philippine Constabulary Air Corps (PCAC). PCAC was renamed as the Philippine Army Air Corps (PAAC) in 1936. It started with only three planes on its inventory. In 1941, PAAC had a total of 54 aircraft including pursuit (fighters) light bombers, reconnaissance aircraft, light transport and trainers.^[2] They later engaged the Japanese when they invaded the Philippines in 1941–42, and were reformed in 1945 after the country's liberation.

Post-War and AFP Restructuring

PAF P-51 Mustang

The PAF became a separate military service on July 1, 1947, when President Manuel Roxas issued Executive Order No. 94. This order created the Philippine Naval Patrol and the Air Force as equal branches of the Philippine Army and the Philippine Constabulary under the now Armed Forces of the Philippines^[3] becoming Southeast Asia's third air force as a result.

The main aircraft type in the earlier era of the PAF was the P-51 Mustang, flown from 1947 to 1959. Ground attack missions were flown against various insurgent groups, with aircraft hit by ground fire but none shot down. In the 1950s the Mustang was used by the Blue Diamonds aerobatic display team.^[4] These would be replaced by the jet-powered North American F-86 Sabres in the late 1950s, assisted by Lockheed T-33 Shooting Star and Beechcraft T-34 Mentor trainers.

The PAF saw its first international action in the Congo under the UN peacekeeping mission in 1960.

Marcos Rule and People Power Revolution

During the 70s, the PAF was actively providing air support for the AFP campaign against the MNLF forces in Central Mindanao, aside from doing the airlifting duties for troop movements from Manila and Cebu to the warzone. Traditional workhorses like the UH-1H choppers, L-20 “Beaver” aircraft, and C-47 gunships were mainly used in the campaign. In the same decade, the PAF Self-Reliance Development Group, the forerunner of the Air Force Research and Development Center (AFRDC) was created. The Center enabled the PAF to create prototypes of aircraft aside on going into partnership with the private sector for some of its requirements.^[5]

In late 1977, the Philippine government purchased 35 secondhand U.S. Navy F-8Hs that were stored at Davis-Monthan AFB in Arizona. Twenty-five of them were refurbished by Vought and the remaining 10 were used for spare parts. As part of the deal, the U.S. would train Philippine pilots in using the TF-8A. They were mostly used for intercepting Soviet bombers. The F-8s were grounded in 1988 and were finally withdrawn from service in 1991 after they were badly damaged by the Mount Pinatubo eruption, and have since been offered for sale as scrap.^[6]

On February 24, 1986 at the height of political struggle between the Marcoses and the Aquinos, the 15th Strike Wing defected to the Ramos-Enrile camp, taking their squadrons of S-76 “Sikorsky” that later dictated the EDSA People Power Revolution which effectively ended the Marcos rule.

1986-1990 Coup Attempts

The following years remained hostile for the Philippines, a series of bloody coup attempts led by then-Col Gregorio Honasan of the Reform the Armed Forces Movement, involved thousands of renegade troops, including elite units from the army and marines, in a coordinated series of attacks on Malacanang and several major military camps in Manila and surrounding provinces, including Sangley and Villamor Air Base, using the T-28 aircraft for aerial assaults. President Corazon Aquino found it necessary to request United States support to put down the uprising. As a result, a large US special operations force was formed and named Operation Classic Resolve, as USAF F4 fighter aircraft stationed at Clark Air Base patrolled above rebel air bases, and two aircraft carriers were positioned off the Philippines. The US operation soon caused the coup to collapse. Additional US forces were then sent to secure the American embassy in Manila. The military uprisings resulted in an estimated US$1.5 billion loss to the Philippine Economy.^[7]

US Military Departure from the Philippines

The Cold War Era has reached its endpoint as tensions between the two ideological rivals, the United States and the Soviet Union, have simmered down as a result of the dissolution of the latter and the massive change of political system among its allies.

The fate of the US military bases in the country was greatly affected by these circumstances, aside from the catastrophic eruption of Mount Pinatubo in 1991 which engulfed the installations with ash and lahar flows. The nearby Clark Air Base was eventually abandoned afterwards, while the Philippine Senate voted to reject a new treaty for Subic Naval Complex, its sister American installation in Zambales. This occurrence had effectively ended the century-old US military presence in the country, even as President Corazon Aquino tried to extend the lease agreement by calling a national referendum, leaving a security vacuum in the region and terminated the inflows of economic and military aid into the Philippines. ^{[8] [9]}

The AFP Modernization Efforts and the Asian Financial Crisis

The importance of territorial defense capability was highlighted in the public eye on 1995 when the AFP published photographs of Chinese structures on Mischief Reef in the Spratlys.

Initial attempts to improve the capabilities of the Armed Forces happened when a law was passed in the same year for the sale of redundant military installations and devote 35 percent of the proceeds for the AFP upgrades. Subsequently, the legislature passed the AFP Modernization Act. The law sought to modernize the AFP over a 15-year period, with minimum appropriation of 10-billion Pesos per year for the first five years, subject to increase in subsequent years of the program. The modernization fund was to be separate and distinct from the rest of the AFP budget.

However, the Asian Financial Crisis struck the region on 1997. This has greatly affected the AFP Modernization Program due to the government's austerity measures meant to turn the economy around after suffering from losses incurred during the financial crisis.^[10]

Several air assets acquired by the Philippine Air Force thru the original AFP Modernization Program of 1995 were the AW109 armed scout helicopters, and airlift assets like the Airbus C295 and CASA C212 Aviocar. ^[11]

A Decade of Neglect

F-5A, now retired from the Philippine Air Force

Since the retirement of the Northrop F-5s in September 2005 without a planned replacement, the Philippine air force was left without fighter jets.^[12] The PAF resorted to the Aermacchi S-211 trainer jets to fill the void left by the F-5's. These S-211's were later upgraded to light attack capability and used for air and sea patrol and also performed counter-insurgency operations from time to time.^[13] The only active fixed wing aircraft to fill the roles were the SF-260 trainers with light attack capability, the OV-10 Bronco light attack and reconnaissance aircraft and the AS-211 warriors (upgraded S-211).

The South China Sea Arbitration Case and Revised AFP Modernization Program

The incidents with Chinese presence in the South China Sea prompted the Philippines to proceed with formal measures while challenging the Chinese activities in some of the sea features in the disputed island chain. Hence, the South China Sea Arbitration Case was filed by the Philippines in 2013 at the International Tribunal for the Law of the Sea (ITLOS).^[14]

Reminiscent to what occurred in 1995, the Congress passed the Revised AFP Modernization Act of 2012, this was meant to replace the older AFP Modernization Act of 1995 signed during former Pres. Fidel V. Ramos’ term, when its 15-year program effectivity expired in 2010.^[15]

Major air assets acquired in this new modernization program iteration are 12 FA-50 Light Fighters, while those programmed for future procurements are the Multi-Role Fighters and the Maritime Patrol Aircraft, among other equipment.^[16]

Flight Plan 2028

In response to regional strategic challenges and perceived internal weaknesses, the PAF has embarked on a transformation process to enhance its capabilities. Flight Plan 2028 is administered by the Air Force Strategy Management Office (AFSMO), and aims to:

• Build the PAF capability to detect, identify, intercept and neutralize intrusions in the Philippine Air Defense Identification Zone (PADIZ) and the South China Sea (to the North and West of the archipelago) from Area Readiness 4 to Area Readiness 3 by 2022.
• Build the PAF capability to detect, identify, intercept and neutralize intrusions into the entire Philippine territory from Area Readiness 3 to Area Readiness 1 by 2028;

The plan calls for a reorienting of the Philippine Air Force from a primarily internal security role to a territorial defence force. It will require substantial organisational, doctrinal, training, strategic and equipment transformation.

US-Philippine Enhanced Defence Cooperation Agreement

On April 2014, the Enhanced Defense Cooperation Agreement was signed by the representatives of the Philippine and US Governments, aimed at bolstering the military alliance of both countries. The agreement allows the United States to rotate troops into the Philippines for extended stays and allows the U.S. to build and operate temporary facilities on Philippine military bases for both American and Philippine forces' use.^{[17] [18]}

Both parties agreed to determine the military installations across the Philippines as covered by the pact, including the former US Subic Bay Naval Base and Clark Air Base, as well as several locations on Cebu, Luzon, and Palawan. ^[19]

As of 2016, four PAF bases and one Army camp have been determined by the United States and the Philippines to be utilized under the agreement. The Air Force Bases are Basa Air Base, Antonio Bautista Air Base, Benito Ebuen Air Base, and Lumbia Airfield.^[20]

Multi-role fighters

There were several occasions that the PAF tried to modernize its fighter aircraft force, which was left to decline for several decades.

In 1991 the newly democratic Russian government offered the PAF several of its aircraft including the Mikoyan MiG-29 and Sukhoi Su-27 during a demonstration held at Villamor Air Base. In 1992 the PAF received offers for both the IAI Kfir and the F-16 Fighting Falcon.^[43]

After the enactment of the 1995 AFP Modernization Act, the PAF made renewed calls to purchase several fighter aircraft, with the initial plan of having 36 multirole fighters in a span of 15 years.^[44] Offers included the American Lockheed Martin F-16C/D Falcon and McDonnell Douglas (now Boeing) F-18C/D Hornet, French Dassault Mirage 2000-5, and the Russian Mikoyan MiG-29. Also offered as alternatives were the embargoed Pakistani F-16A/Bs and ex-French Air Force Mirage F1, and ex-South African Air Force Denel Cheetahs which were rejected as the government was then inclined on obtaining new-build platforms.^[45] However, these modernization programs were put on hold after the Philippines' economy was impacted by the 1997 Asian Financial Crisis.

Renewed interest would later come on used platforms. In June 2010, the Department of National Defense (DND) was also looking at Canada for used CF-18s or France for its used Mirage F1s, although no decision or purchase came up.^[46]

In December 2011, the DND and Department of Foreign Affairs (DFA) was tasked to formally request at least a squadron of 12 ex-USAF F-16C/D fighter jets, most probably Block 25 or 30 which would be refurbished to either Block 50 or 52 standards.^[47] This was discussed during the US-Philippines "2+2" Meeting on 30 April 2012. The Philippine government would pay for refurbishing, maintenance and pilot training which would run for two years.^[48]

However, by 2012 the maintenance costs for the used fighters were found to be too high so attention turned to new jet trainers that could be converted into jet fighters. The requirements were listed as "supersonic ability, multifunction displays and On Board Oxygen Generation System."^[49] A DND spokesman has said that aircraft from France, the United Kingdom, Italy, and South Korea were considered.^[50]

It was reported that the DND will be acquiring multirole fighters by 2018.^[51]

In responding to the Philippine desire for multirole fighters, the United States offered variants of the General Dynamics F-16 Fighting Falcon, and Sweden offered the Saab JAS 39 Gripen.^[52][53]

Close air support aircraft

The Philippine Air Force is looking to replace entire OV-10 Bronco fleet which are currently used for close air support and aerial reconnaissance platforms. Being considered are the Hawker Beechcraft AT-6B Texan II, Embraer EMB-314 Super Tucano, KAI KA-1 Woongbi, Elbit Systems L-159, and reportedly, the Air Tractor AT-802U.^[54] A decision from the PAF & DND was expected to be released by July 2012, but was moved to the fourth quarter of 2014 due to bureaucratic constraints.

Hawker Beechcraft demonstrated their AT-6B Texan II, together with their other aircraft line, in April 2012 with a display at Clark Air Base.^[55]

On 20 June 2012, it was reported that the Embraer EMB 314 Super Tucano from Brazil is a possible contender for its aircraft for a total of 6 units, which will be acquired for PhP4.968 billion (USD 115 million).^[56]

In late November 2017, a statement by Embraer noted that the Philippine Air Force had placed an order for 6 Super Tucano aircraft.^[57][58][59]

Attack Helicopters

As of 27 April 2018, negotiations are ongoing for the donation of 2 Bell AH-1F Cobra attack helicopters and several dozen M113A2 armored personnel carriers from the Kingdom of Jordan to help the Philippine Government combat ISIS terrorists.^[60].

The Philippines will acquire 24 light-attack helicopters for its requirement, they will procure these helicopters on Horizon 2 Phase, AFP Modernization which covers 2018-2022.

Combat Utility Helicopters

Following the abrupt cancellation for the order of 16 Bell 412EPi Helicopters from the Canadian Division of Bell Helicopters through a government-to-government contract with the Canadian Commercial Cooperation (CCC)^[61], parent company Textron, Inc announced on 27 April 2018 that negotiations were ongoing for the continuation of the sale using their factory in Texas, USA as the manufacturer.^[62]

During a hearing by the Senate for the budget of the Department of National Defense for 2019, the Commanding General of the PAF confirmed that there are four shortlisted helicopter models for the Combat Utility Helicopter acquisition project: the Bell 412EPI but specifically sourced from the US instead of Canada, the Sikorsky Black Hawk which is considered an expensive option but can be considered based on the package included in the offer; Leonardo's AW139M helicopter, and Russia's Mil Mi-171.^[63]

Light lift aircraft

On 20 June 2012, it was reported that the IPTN NC-212 Aviocar light lift transport aircraft from Indonesia was chosen and a total of 2 units will be acquired for PhP 814 million (USD 18.9 million).^[56]

On September 26, 2013 the DND declared PT Dirgantara Indonesia/Indonesian Aerospace (PT DI/IAe) as the only qualified bidder. They are offering the Series 200, Series 300 and the Series 400 versions of the IPTN NC-212 Aviocar.^[64] The version to be delivered is the NC212i, the new generation of aircraft types NC212-200 or NC212-400.^[65] A notice of award was issued by the DND to PT DI in January 2014 after clearing the post-bid qualification requirements, and PT DI is required to deliver the aircraft within 548 calendar days from the opening of the letter of credit.^[66]

Seaplanes

In November 2013, the DND released an invitation to bid for the acquisition of 3 brand new Search and Rescue seaplanes with an Integrated Logistics package (ILS). The DND has allotted 2.67 billion pesos for this project. The pre-bid conference was scheduled at November 15, 2013 while the actual bidding was scheduled at November 29, 2013. The seaplanes being offered should be used by the Armed Forces of the country of origin or by the Armed Forces of at least 2 other countries.^[67]

Long-Range Patrol Aircraft

On 1 July 2014, President Benigno Aquino III announced plans to acquire 2 long range patrol aircraft.^[68] A budget of P5.976 million has been allotted under the revised Armed Forces modernization program.^[69] Companies reported to have bought bid documents include Alenia Aermacchi, Airbus Military and Elta System Ltd.
