yes i agree D-west is deep water survival training, an advanced course for water survival. Dropped off in heavy water off San Diego (about 10 miles out) and they leave you there to think about it for an hour or so with just what you bring in your survival vest and LPA. I was sure a shark was swimming around me, very weird feeling, then i heard the chopper come in for a horse collar pickup. Just another day in NAVAIR!
On the corrosion front, the p-3's i flew around with worked best around 200' off the water. The salt would cake up on the windshield ¼" thick. At moffett (and many other NAS's) used a fresh water "bird bath" like a drive through car wash after every flight really helps with the corrosion.... but it is always learking somewhere...
