Sixteen of the Joint Offensive Fighter Wing's KA-11P Phoenix jets took off from Shin Ui-joo Airport and flew along the border of the Ap-rok River. The jets split into groups of two and moved toward their assigned areas.
The 16 Phoenix jets flew at low speeds in an altitude of 500 m, then dropped off the land sonar Landmark-1 in order.
Boom! Boom! Woooooooosh~
The Landmark-I was 1.2 m in length and 150 mm in diameter. It embedded itself onto the surface by using its falling momentum, then a radar in the shape of an umbrella popped out from its side. The high-precision sensors that faced the ground began checking for vibrations and sent the data to the Joint Offensive Fighter Wing's Command Headquarters in real time.
