Although the little huddle of three ship-ettes there on the right is interesting. Those are the three Cyclone-class patrol ships that are apparently going to a foreign buyer.
...and a bit of Googling tells me that this is the USNS Charlton, a Watson-class vehicle cargo ship, in the Philly Shipyard for an overhaul. 950 feet long and a 106-foot beam is a big ship, which should give you an idea of the size of that dydock. The Watson class are built right to the Panamax limits.
