You'll note in the link you cite that the missile used in this system is a derivative of the Kh-35 anti-ship cruise missile, which Russia can launch from most of their combat jets and various helicopters, several of which are also operated by Ukraine. The missile is fundamentally an air launch design. When launched from a ship, shore battery or helicopter a booster is used to accelerate the missile to cruise speed. A booster is unnecessary when launched from a high speed aircraft. Now, I don't know whether Ukraine has retained air launch capability in the derivative, but that is plausible. I do know that war motivates tremendous initiative, so if not you can bet they're working on it.
