    Larger images of the photo session.

    INS Vikramaditya is the odd one out in that group with almost invisible trail. Those 4 screws are revving at low speed slicing the fluid very efficiently with low cavitation and still keeping up with the other two carriers,

    Perhaps the other two vessel has the Prairie-Masker system installed and running? This uses air bubbles to mask ship noise.

    I don't think Nimitz has a Prairie-Masker. Izumo wake is so prominent though that maybe she does have some sort of acoustic covering system in use.

    The Japanese ship is running on two shafts plus it looks like shes quite high in the water there and she has 10ft less draft to start with. I dont think theres anything strange in screws working harder, shallower in the water, leaving a more pronounced wake than a couple of larger 4-shafters alongside.
