Firing blind

[Mush Martin]

Well after a fashion sure.

Stuff that effects your visibilty is
Light ( How much of a moon )
Chop ( to break up the shape)
Speed( to reduce wake)
Aspect (ie angle of silhouette of ship that target seas.sideview bad
frontview good back view best.)
Noise (if semi submerged you generate a sound signature.)
Go Dark ( inspite of what you think the IJN can direction find
on your radios and radars. so maintain emcon )

make approachs based on keeping your profile minimized throughout.
Make major maneuvers prior to visual contact, you know where they
are, you dont need to see them to gain advantageous position, but
you do need to gain advantageous position so they have much much
less of a chance detecting you.

Ideally you would be in firing position decks awash aligned with
the final firing angle ass backwards, you would wait until the
enemy group moves from coming into visual until they pass directly
across your firing point, with a measured spread shooting the
combined overlapping silhouette of the convoy, with out maneuver
you would just hit 1/3 then 2/3 surface totally then ahd std then full ahead and book out with out showing anysingle thing that shows above
the troughs.

Still nights always require less and slower movements
if moon is more than half prosecute from radar depth.
