I snuck into Tokyo Bay with my Porpoise-class Shark and tooled around looking for photo opportunities for three days! Bugger boat doesn't have battery life for more than 80 or so kilometers, forcing me to surface at nights in the middle of the bay to rekindle the stove. While stuck on the bottom waiting for night, a TF presumably scooted aside towards Chiba, yet when I went looking for it said TF had used its cloaking device and vanished in the haze. Poofters! I finally snapped a long range photo of some hapless ship and am now slowly wending my way out. Immersion went down the drain on this one, seeing how little activity there is on behalf of patrol ships etc. I did get DCd for a while but they lost the scent (in shallow water too!) and went back to sipping tea, the bastards.
