Back in September land-dwellers were on high alert as a submarine passed through the waters of the East River. It turned out that the sub was the U.S.S. Growler, heading to the GMD Shipyard Corp. facilities at the Brooklyn Navy Yard for some repairs. Now (really, right this second) it's making its way back to the Intrepid Sea, Air & Space Museum. From the press release:

The refurbished Growler Submarine (SSG-577) will return to its home at the Intrepid Sea, Air & Space Museum at the Hudson River Park's Pier 86, located at 12th Avenue and 46th Street in Manhattan on Thursday, November 6, at 1:00 p.m. The Growler, which received an exterior refurbishment while in dry dock, will be towed by tugboat to Manhattan's West Side, in advance of the Intrepid Museum's reopening on Saturday, November 8th.

Take a look outside if you're in Lower Manhattan, it should be passing by your windows right now. Once back at the museum it will undergo some interior refurbishment, and will be open to the public in the spring of next year. Last month the Intrepid itself made its way up the Hudson to return to Pier 86.
