Nuke confirmed! Users have found that if you reach prestiged all 5 Divisions at least once in Call of Duty: WWII, you will be rewarded with an additional streak — the V2 Rocket which is similar to the Nuke stream in previous Call of Duty titles.
Once you have prestiged all 5 Divisions at least once, you will unlock the V2 Rocket. In order to acquire the V2 Rocket to use in game, you need to go on a 25 gun kill streak in a match.
