Caption: In response to customer concerns about ASW threat posed by MPAs and helicopters, DCNS unveiled a compact, canister-based submarine air defence weapon system at Euronaval 2012, involving MBDA's Mistral short-range infrared homing missile fired from periscope depth. (DCNS)
Ascending to periscope depth, George Washington went through an acoustic thermal layer that had hidden the engine and propeller noise of Nissho Maru.
When the submarine is at periscope depth -- i.e., with the mast fully raised -- her steadiness depends on how deep in the water her hull is.
The 116-crew vessel, based at Faslane on the Clyde, normally lurks deep beneath the waves, but has to rise to periscope depth - some ten feet down - in order to fire its missiles.
"A submarine could easily come to periscope depth, and a U-boat running on the surface was virtually invisible to radar and sonar back then."
Had these been followed, the accident would have been avoided because the submarine would have been slowed down and returned to periscope depth when numerous vessels engaged in fishing were first encountered."
Going to periscope depth means typing in your ordered depth and the computer adjusts the ballasting as necessary.
At periscope depth was the retired chief of the defence staff, Admiral Lord Boyce.
"The submarine has to stop what it's doing and come to periscope depth to raise its antenna," said Bill Matzelevich, senior manager of business development at Raytheon Co.
They are able to "breathe" through a snorkel at periscope depth and can remain deeply submerged for extended periods at slow speed.
Periscope depth is a very dangerous evolution for a submarine because all of the submarine, minus the tip of a persicope remains underwater so oncoming ships can't see the boat.
Michael Coen, the officer of the deck, to rush through procedures for bringing the submarine up to periscope depth to do a visual search before performing the ''emergency blow'' rapid-surfacing maneuver.
