When launching a fox-3 missile (RB 99) at long range when the missile is locked with its onboard radar, it starts spinning out as soon as the enemy visually de-renders and if not supported by TWS or STT.
It happens nearly every single time i look away and / or stop holding the TWS on the enemy and the missile doesn’t hit.
Here is a link to an in-game clip showcasing this, it can be seen on it that the missile spins out at the exact same time the enemy de-renders:
