我找到的資料J15D 2018年就上艦了...
殲-15D于2018 年開始進行作戰測試。其在航母上的部署使中國成為第二個擁有專門艦載電子戰飛機的國家。
在2022年3月官方發布的山東艦訓練視頻中,首次出現了“飛鲨”電子戰型號殲-15D
In addition, a J-15D, the electronic attack variant of the “Flying Shark”, was seen for the first time on board the Shandong in official publicity footage of the carrier’s training in March. With some armaments removed and replaced with electronic warfare pods and other electronic equipment, the J-15D is designed to detect, track, interfere and suppress enemy radar and other electronic communication, to provide protection for the ship-borne fighter fleets.
J-15D began operational tests in 2018. Its deployment on the carrier made China the second country to have specialised ship-based electronic warfare planes.
