F-CK-1A- History, Design, Performance and Discussion

History

Spoiler

The F-CK-1A is Taiwan’s first indigenous jet fighter. Development started in 1978 when diplomatic relations with the U.S. were rocky and the Republic of China Airforce (ROCAF) foresaw the need to develop its own fighter aircraft instead of relying on the U.S. for new ones. Following refusals to allow Taiwan to purchase new fighters such as the F-16/79 and F-20 (F-5G) President Chiang Ching Kuo decided to expand the Taiwan defense industry.
Plans to upgrade their fleet of F-104’s or F-5E’s were put forth but eventually a project design called the XF-6 was decided on. This aircraft design had a delta wing with canards and would perform as an interceptor. This project design however didn’t get very far and was instead developed into the “Anxiang Project”.
In 1982 the “Anxiang Project” a plan to research and develop an indigenous defense fighter was submitted to the Executive yuan. The project underwent multiple phases and had assistance from the US (Mainly from General Dynamics).

General Dynamics assistance phases:

Stage 1: GD analyzes the military strength and aircraft performance requirements of the ROC according to the enemies capabilities and the situation.

Stage 2: Review the research report of GD and decide whether to continue to develop our original design (C-2) or carry out a new design of GD (G-2) and provide the necessary support for GD.

Stage 3: Send staff to carry out the preliminary design at GD Fort Worth, TX Branch

Stage 4: GD sends staff to Taiwan to help complete the project

When the two sides met up to choose which design to go through with, Mr. Anderson of GD presented the “G” design and Hsi-Chun “Mike” Hua presented NCIST’s “C” design. The “G” design won out but incorporated elements from the “C” design to create the joint SE-1 design.

C-2 design had two tails and a “beaver tail” elevator.

The project was divided into 4 phases:

Ying-Yang (鷹揚): development of airframe
Yun-Han (雲漢): development of Powerplant
Tien-Lei (天雷): development of avionics
Tien-Chien (天劍): development of air to air missiles

On December 10 1988 the first F-CK-1A (10001) rolled off the factory line and was displayed to the public for the first time. Them President Lee Teng-Hui named the fighter “Ching Kuo” in honor of the former president Chiang Ching-Kuo who had died earlier that year.

On May 28 1989 the F-CK No 10001 was successfully tested and soon a second prototype was made. Eventually multiple test flights were made and subsequent adjustments were made as a result of those flights.

In April 1992 the 427th wing of the 7th squadron received their first F-CK-1’s and started training on them.
