Virginia class sub question

[Timothy L]

I am currently beginning my second submarine, a 1/72 Virginia class block III. I see that the fins on the stern are not symmetrical. On the right side of this photo the top fin is capped off with a bullet shaped object. The lower fin on the right side has an odd protrusion. I would be most appreciative if someone could share with me what these shapes represent. Thank you in advance.

PS I did find a reference stating “the port anhedral has a hydrogen diffuser pod and the starboard anhedral has a towed array tube” . The locations referenced of port and starboard do not fit the port side only depiction shown on this model. Perhaps the description referred to a block I or block II? In any event it puts me a little closer to the answer
