This is the air base responsible for the Transport Wing of the PAF, where the Hercules, Fokkers and Nomads are found and based. When fighters are stationed in the area, it is always recognized as the base of the defenders of the Philippine's southern backdoor. The 7th TOG's Broncos are loaned from 16th Strike Sqn. The 20th TOW (formerly 205th Helicopter Wing, 205th Airlift Wing) relocated from Villamor AB in 2001.
In June 1996, Mactan Air Base was renamed Benito Ebuen Air Base in honor of the PAF Commanding General and the pilot of the ill-fated presidential plane 'Mt. Pinatubo' which was carrying President Ramon Magsaysay that crashed in Mt. Manunggal in March 3, 1957, killing all 25 aboard. Gen. Ebuen, who was also a commander of the 5th Fighter Wing, was also famous in piloting the famous PAF P-51 Mustang known as the 'Shark of Zambales'.

In 1920, the United States Military opened Clark Air Base, as part of its installation, Fort Stotsenburg. After World War II it became the largest US Air Base outside the US mainland and served the US 13th Air Force which became the operational USA base in the Far East. On November 21, 1991, though, the base was turned over to the Philippine Government and converted it as an international airport and Special Economic Zone. However, units of the PAF are also stationed in the once sprawling US Air Field located in Angeles City, Pampanga Province.
The base was first named after Maj. Harold Clark who was stationed in the Philippines but died in a seaplane crash in the Panama Canal Zone on May 21, 1919. President Gloria Macapagal-Arroyo renamed it in memory of her father, former President Diosdado Macapagal. Now an international airport, it houses local and foreign carriers as well as cargo companies servicing routes to Manila, Cebu, Laoag as well as certain cities in People's Republic of China, South Korea and Taiwan.

It is located strategically in Sangley Point, Cavite and used by the United States Navy prior and during World War II until it was handed over to the Philippine Government in September 1, 1971.
It was renamed Atienza Air Base in honor of Maj. Danilo Atienza, an F-5A jet pilot who failed to pull out during a bombing run and crashed in the area while leading a trio of F-5's to destroy the RAM-SFP 'Air Force' during the December 1989 coup attempt against former Pres. Corazon Cojuangco-Aquino. Today, as it has been, the Base houses the 'Bronco', 'TurboChargers' and 'Defenders', equipped 15th Strike Wing of the PAF responsible for the main CAS and COIN air support operations of the AFP. The 15th Strike Wing is the "mother" unit.

Air/Radar Stations

Air/Radar Stations
Radar stations were in used during the 60's to the 80's and covers the entire Luzon area and parts of Visayas. These stations primarily provide ground direction for the F-5's and F-8's and worked in conjunction with the then American radars in Clark and Subic. PAF radars covers during the day and the USAF handles nighttime intercepts. By the time the Americans left, radar coverage was nearly zero reducing the F-5's effectiveness and partly led to its decommissioning. Some of the stations received equipment left from the American bases, particularly the AN/TPS-32 Automatic 3-Dimensional Tactical Long-Range Surveillance Radar which is a transportable radar for the HAWK AD system, unverified reports including from Jane's Weapons Systems '84-'85 edition of HAWK SAM emplacements being employed by the AFP, are apparently USAF HAWK systems but tied to the Philippine Air Defense System (PADS), therefor included in the Order of Battle. When the Americans left, a single mobile 3-D radar was reportedly acquired but minus the SAM, and is believed to be emplaced in Rio Tuba, Palawan. With the country enmeshed in the Kalayaan Island Group dispute and the protection of the Malampaya Gas platform, several radars were quickly brought to operational status although most of them are online for a limited duration. Only Wallace Air Station is said to be fully operational as of 2006. All units report directly to the Air Defense Wing, Air Defense Alert Center in Air Force City regardless of location though units like Zamboanga and Rio Tuba also report operationally to local operational wings. The Air Defense Wing's funtion it to provide air defense and air space control throughout the Philippine Air Defense Identification Zone (PADIZ). All of these stations are owned and manned by PAF personnel and are separate from the joint ATO-PAF manned ATC radars.
