FrozenVent posted:Funny, most of the ships I've been on had Sperry radars... including the ones built in Japan. I mean it depends on the ship/age/class but when I said Furuno I suppose I should have been more general and meant a commercial nav radar. As far as I know (and I'm not much of a Nav guy) the Furuno and Sperry s and x band radars are pretty similar no? I always associated Sperry with VMS/IBS systems and Furuno with actual Nav radars but that could be my ignorance.

Also wanna make the point that in a ~war scenario~ Anything you're picking up coming toward you using an X band is a small boat (which probably needs to be blown up I guess, don't do 40knots with a 0cpa) Surface search radars don't have any use against real threats posed by enemy surface combatants at expected engagement ranges. Every weapon we care about is pretty much an OTH antiship missile. (Not breaking any NDAs here, theyve said this in plenty of public disclosures) Hence, navy ships have Sperrys for navigation alone and dont give a gently caress about radiating during non-operations.

Edit: beaten Also from probably the only solidly useful navy school I attended that was 100% dedicated to driving a ship at sea, the guy interpreting the colregs to say that "if you weren't using radar and you got in a collision then you're at fault for not using radar" is correct. Yes the military has special needs to be sneaky but is not exempt from colregs, and I don't think sagami wan or sea and anchor detail (the circumstances of these collisions) are relevant scenarios to being sneaky.

Radars had nothing to do with the crashes. Afaik fitz crew wasn't paying attention and the mccain one was equipment failure.

Potato Salad posted:What is this referring to? The San Francisco colliding with an underwater mountain at flank. I've heard the story multiple times that while only the one guy who was smoking died, but that hours before they had the sonar dome open for cleaning on field day, which would have doomed the entire ship. For Two Finger et al: Sonar dome is at the very front, and is a dry space with all the sonar electronics, theres a crawl way through the ballast tanks with a thick watertight door on the main pressure hull. The sonar dome itself isn't particularly structural and when the San fran hit the mountain it crumpled in like a soda can. The pressure hull, being thick steel, was fine, but had that watertight door been open the front of the ship would have quickly flooded and doomed the ship.

Is driving the boat at flank while having a critical WT door open something that happens often would you say?

The transducers all face outward into the flooded part. But the electronics still need to be in a dry space that people can get to for installation and maintenance. As for unhardened, that's a bit of a misnomer. It's rated the same as anywhere else for depth, but slamming into a mountain at flank isn't quite the same as withstanding a shitton of fairly uniform pressure.

The cool thing about the sonar dome being like this is that the sonar techs get to store poo poo there (with CO approval) on westpac.
