Dead Stick Moves

Navy NewsStand has two good pictures of USS Asheville (SSN 758) heading into the drydock Arco (ARDM 5) in San Diego:

It doesn't appear that Asheville is snorkling in either picture, although I suppose they could have secured the diesel before heading over the drydock sill. On the other hand, they may have done a more manly "battery only" move that my old boat USS Topeka was infamous for in San Diego back in the early '90s. It's a lot easier -- as long as nothing goes wrong. Does anyone know if battery-only deadstick moves are coming back into style?
