Spike fighter-bomber is a product of unsuccessful bidding. It is unfortunately defeated in the improved competitive general fighter-bomber with jf1 blunt hammer, but its high-speed penetration ability is favored by bomber squadrons. Therefore, it officially entered the service sequence. This machine is consistent with the improved jf1 blunt hammer, and both are named by the original serial number given by the competitors, and are nicknamed by the military. This also makes the numbering of the two machines inconsistent with other similar models.This machine has a conservative electronic control system and is a two-seat model.The work was released in a limited time as a celebration of New Year's Eve in China. At the same time, I also wish all my friends who have seen this work happiness and all the best in their life this year. Please give me an up if you like.
