Defiant 300 aircraft: ingenious Filipino invention

Another invention of Filipinos that became “trash” due to the lack of support from the government is the Defiant 300 aircraft. It proves Filipinos ingenuity in developing military hardware that poses capability in defending the country from threat if further improved. The Defiant 300 is a prototype turboprop aircraft designed for light attack, counter insurgency (COIN), close air support, aerial reconnaissance missions in low threat environments, as well as providing pilot training. It was made through the cooperation of Philippine Aerospace Development Corporation (PADC), Philippine Air Force (PAF) and the Philippine Aerospace and Sciences Foundation (PASF) in 1986. It was designed to operate in high temperature and humidity conditions in extremely rugged terrain and very suitable in the type of conditions that the Philippines’ have.

The Defiant 300 aircraft
Only one prototype was completely built and another one in an incomplete airframe. The aircraft made its first flight in 1987 which lasted in little more than an hour. The brain and the main designer of the plane was Capt. Panfillo Villaruel who also contributed to the design of the first indigenously built PADC Hummingbird helicopter.

The Defiant 300's fuselage was composite construction (wood and fiberglass) and was powered by a 300 hp Lycoming piston engine. Landing gear was taken from the Beech T-34 and provided by the PAF. The intent of the program was to provide the PAF with a trainer and light strike aircraft similar in performance to the Brazil’s Tucano. The Defiant 300 was to have been followed by a larger version equipped with a turboprop engine and designated the "Defiant 500". The overall cost of the project at that time (1987) was Php40 million.

The project languished soon after the development of the prototype because of lack of government support. Currently, the sole remaining prototype now lies abandoned and display at a hangar in Philippine State College of Aeronautics.

  1. From the building of this aircraft to the time it was flown by Capt. Panfilo Villaroel, I was there. Capt. Villaroel flew with me in a Cessna 172 as a practice flight. I was one of the founders and Board of Trustee of the PASF (Philippine Aerospace and Sciences Foundation).

    2. We should have pursued the development of this aircraft to satisfy Presidential Decree 415 as basis for real AFP modernization.
      The abandonment of this project reflects our disinterest in research and technology as a people. The government must lead the way for our talents and engineers to attain self reliance on defense.

  3. The Government should encourage Filipino talent to grow; in design, R&D, and manufacturing. The Defiant project and the likes of it should be encourage by the government. We will not be able to cope up with other countries in development if Filipinos will not start it's own R&D. It may be costly but it's only the way to learn and progress. Great countries have reached their advancement also with great costs. Buying readily available equipment abroad maybe cheaper than creating our own, but with this mindset, we will lag behind in the long run.. Philippines should learn new technologies and start building our own....

  5. nkakapanghinayang talaga. nakakalungkot isipin na nakakaranas tayo ng panghaharas galing sa bansang china. nkakalungkot isipin na sa sarili nating bayan makikita mong di tayo safe pagdating sa maraming bagay.

  6. ang basehan lang naman ng feasibility at possibility nito para gawin ulit ay kung mura nga ba ang gagastusin. pag develop nga lang ng uav eh nahihirapan na ang gobyerno. kung pwede lang hingiin ang mga na pro procure na mga armed forces assets eh talagang manghihingi nalang kesa bumili. hindi naman kasi mahirap ang bansa kaso na ingrained na sa pinoy ang "poor-mentality" parang nawala na sa pinoy ang tunay na pinoy pride. hindi naman kasi mahalaga kung mahirap ka, ang importante we as a nation is creating and making efforts to spell success. kaya namang gumawa ng eroplanong trainer, with the advent of software technology naniniwala akong mas mura na gumawa ng mga high tech na kagamitan kesa noon.

  7. nakakahinayang po ito, kahapon nakita ko ito sa hangar sa loob ng PHILSCA campus. kung pinagbuhusan lang sana ng pansin ito ng gobyerno natin malamang nagpoproduce na din tayo ng sarili nating mga eroplano.ang iniisip kasi ng ibang nasa kapangyarihan eh kung paano kikita at magbubulsa ng pera para sa sarili nila.

  13. Pwede naman i continue Sa dami ng mga talented engineers Sa bansa at softwares na makakatulong Sa paggawa ng ibang designs para wala sabit Sa patent. Sa dami ng OFW na mayayaman or investors any group gawa kayo ng website nyo at ipakita nyo Sa buong mundo ang projects nyo. With complete license n permit etc, for sure madami ang mag-iinvest or donate Sa paggawa ng kahit ano pang inventions nyo. Huwag na masyado umasa sa Gobyerno dahil baka matagalan pa at marami silang problema Sa bansa. Drugs, corruption poverty etc. Ituloy nyo lang pag maganda mapapansin yan. Mabuhay ang mga Pilipino.

  14. Wag na po tayo umasa sa gobyerno. Wala po alam ang ating gobyerno kundi mangurakot at magnakaw. Magabroad nalang tayo at dun mapapakinabangan ang ating talino at talento. Kung magaling ka magenglish, aba, eh bagay ka sa pinas kung saan naglipana mga call centers dito na pumapatay sa teknikal na industriya ng ating bansa. Isa akong aeronautical engineer sa PADC. As of 20 January 2017, pabulusok na pagbagsak ang ahensyang ito. Wala na tayo maasahan at wag na tayo umasa sa gobyerno ng Pilipinas.
