Does anyone have any good information on the CCIP pipper-on-a-string type of bomb targeting, specifically how/when it was developed? Also, is that a strictly Western thing, or is it universal?

Pablo Bluth posted:The first of the Royal Navy's Astute class subs have apparently completed their trials and are being prepared for service. The Telegraph posted:The Astute class submarines have cost more than £1 billion each and are among the most advanced in the world. They can circumvent the globe without surfacing, carrying a payload of dozens of cruise missiles and torpedoes.  They... can sail through space? MrYenko posted:I don't think there are any solid numbers on it, but I'd be somewhat surprised if a modern nuclear submarine could come anywhere near the crash-dive times of a WWII diesel/electric. Nuclear submarines spend so much of their time already-submerged that a crash dive simply isn't terribly useful, anymore. Also, a Virginia or Astute is much, MUCH larger than any common WWII submarine. Virginias are ~7900 tons, Astutes are ~7400, and a Type VII was ~870. So, huge mass differences probably means unlike dive times. This is basically correct. A modern USN SSN is much more massive but also much more powerful than a WWII fleet boat. It really has no reason to be on the surface except when piloting in to a harbor or channel. There is an equivalent to the old crash dive called 'emergency deep' which is usually conducted from periscope depth if a close-aboard contact is discovered that might collide with the ship. Since the ship is already submerged and trimmed to neutral buoyancy, it rings up a flank bell and drives down as steeply as possible without broaching the screw. Old-timey crash dives are hard for modern boats because they have huge main ballast tanks to provide buoyancy to counter their mass, and the MBT valves are basically the same size as the WWII boats'. Also, a modern bridge is rigged with a bridge box (internal comms, compass/engine order repeater, etc), radar repeater screen, safety rails, windscreen, commercial radar, and other junk that needs to be disconnected and stowed before the whole sail is re-rigged for dive. Crash diving from the surface just isn't a skill that's needed anymore.

Psion posted:I would actually be really interested to know how DC was handled on carriers before and after. I'm curious if the changes - I assume there were quite a few, hah - were primarily equipment retrofit or procedural changes. Or both? I know about the deck edge spray system and more all-hands mandatory DC training, but details. This must have been posted earlier in the thread but we watched this in boot camp (2002): https://www.youtube.com/watch?v=U6NnfRT_OZA Like Fearless said, DC went from a specialized artisan craft of DCmen who handed down damage control lore to their selected apprentices to something everyone is prepared to do at any time, until they die or the boat stops killing them. Favorite part: one team has coated the fuel with foam and smothered the fire, then another team blasts it with high-pressure seawater, blows the foam off, and the whole thing reflashes  I can only imagine that a stupendous amount of institutional DC knowledge and attitude had been lost between WWII and then.

My grandfather invented war. Stealth aircraft rely on precisely angled surfaces to reflect RADAR properly. What happens when the pilot uses his controls? The ailerons and rudder can't be stealthified through their full travel, can they?

That's my point: I'm reading http://www.amazon.com/dp/B00A2DIW3C/ref=pe_245070_24466410_M1T1DP and he mentions that not fully closing a panel completely compromises the plane's RADAR cross-section. That got me wondering - if a few loose bolts could compromise LO, what happens when the ailerons or rudder deflect?

The British certainly have recent experience with building and operating marine nuclear reactors. If the primary purpose of a carrier is long-range force projection, does anyone know why they chose conventional propulsion for their new one?

Could someone do a brief history/system explanation post of the CCIP bomb sight? All I know from Jane's USAF (hell, going back to Microprose Strike Eagle for Commodore 64 I think) is that it's a pipper hanging from a "string" that indicates the fall path of the weapon and the projected impact point based on the platform's speed and altitude. Who came up with it, and when? Is it a western thing, or do WP and descendant aircraft use it too? Are/were there competing alternative systems? Finally, if you're approaching a target on a ridge or hill a few hundred feet higher than the ground that's under you right now, is it smart enough to use some kind of radar to adjust itself accordingly, or does it assume that you're flying over a flat plane and rely on the pilot to adjust for the target's altitude? PGMs make the last question somewhat moot, but I would imagine that development and training don't assume that you'll always have PGMs. Thanks!

You can bet that the Russians have a "special plan" for us if this is the case. It might not be all-out invasion, but some sort of hybrid warfare we saw in Ukraine. When you say 'us', are you speaking as someone in a former SSR that is currently a NATO member*? I can't believe an actual shots-fired Russian invasion of a NATO member would fly, but I guess it depends on what people let them get away with. * you're in Estonia, right?

Suicide Watch posted:If it's visual and senses something that has a really large IR signature or something with a IR signature resembling an incoming missile, wouldn't it be really easy to render these detectors ineffective by saturating the environment with lots of IR projections? It could combine IR detection with a rangefinding laser to identify a detection as a closing contact (there's already a laser in the system) but I'm really just spitballing here which is why I asked. I didn't see anything on the Northrup Grumman page about how it works.

Phanatic posted:That's not how IR imaging works. Thermal imaging, yes, but that's not the same thing as infrared. I still don't quite get the distinction. My caveman understanding of thermal imaging is that it interprets primarily IR radiation from an object as varying levels of heat. I have a set of cheapie "generation 1+" or somesuch Belarusian NVGs. It has an IR illuminator that works basically like your TV remote example; it shines a little light that happens to be outside the human visible spectrum but is visible in the goggles. I can see the difference in how my goggles see the world vs. how a real thermal imager sees it, but I guess I don't understand why one form of IR radiation is visible (when reflected) but I can't see the IR radiation that an object is naturally emitting. Different topic: why did/do the Aussies love the F-111 so much? From my POV, it seemed like kind of an embarrassing hybrid of a bulky fighter (at a time when Vietnam was showing that actual combat maneuvering still counted for a lot) with an OK but not great penetration bomber. It had a lot of newish and flaky technologies and crippling design compromises and never really filled any role well with the USAF (nor USN lol). Tellingly, not a single film exists that pairs an F-111 with either a homoerotic volleyball game nor renowned star of stage and screen Lewis Gossett, Jr. Every account I've heard of Australia using it, though, makes it sound like Ned Kelly eating Vegemite Tim Tams while singing Waltzing Matilda. What did they 'get' about it that we overlooked? I had a question earlier about why Canada, which has no carriers, would fly the CF-18 and the answer was basically that it filled the cost/capability gap between the F-16 and F-15, and the extra CATOBAR strengthening of the airframe and undercarriage was actually a bonus on rough runways. Is there something about the F-111 that makes it a great plane for the outback or filled some other unaddressed need in the RAAF but wasn't needed or appreciated in the USAF?

Helter Skelter posted:Different wavelengths. NVGs are typically sensitive in the near-infrared spectrum (0.75–1.4 µm). Thermal imagers work off of long-wavelength infrared (8–15 µm). Just like your eyes can't see near-infrared light unassisted, your NVGs can't see the long-wavelegth stuff. Oh, huh. That makes sense now. I just looked at an electromagnetic spectrum diagram for the first time since high school and I guess I never appreciated how both UV and IR cover like ten times the width of the actual visual spectrum, each.

My God, those things really were flying boats. Like not airplanes with watertight hulls that could land on the sea, like an actual ship that happened to coincidentally have wings and the ability to fly. There's a crewman wrenching on an engine in flight in that diagram FFS. As economically unviable as it is stuff like that makes me want stuff like zeppelin travel to come back so much.

Godspeed, flying banana.  My grandfather who imported furniture from Europe apparently bought a stack of the famous US helo shootdown postage stamps from Vietnam because they were actually illegal to buy in the US. I'm sure it seemed like a good investment in the mid 1960s but Vietnam printed enough of the things to tank any secondary market or anything. They're collectively worth like $20 today.

wkarma posted:If you look carefully at that picture, you will see that the E-2 (the one with the big radar on top) is sitting basically ready to go on one of the waist catapults (there are 4 catapults, the two up at the bow and two that roughly follow the landing area). Behind that are 4 hornets that would be the next to launch and would coincidentally free up the angle deck for landing ops. You can also see the H-60 rescue bird that would be the first to launch if flight ops started. Are the waist catapults the two strips that seem to converge on each other on the port side of the landing area? I never knew they even had those.

So an AGM-114 Hellfire has apparently turned up in Cuba. Aside from the violation of export restriction &c, what's the damage? It's been exported to like 30 countries and from my very limited understanding of this kind of thing, it's about as simple as guided missiles get. I don't want to downplay the implications of military hardware ending up in unfriendly nations, but technically speaking is this a big deal? It's not like Cuba is going to start an indigenous AGM industry, and whoever they sell it to - China, Russia - already makes missiles that do the same thing: go to that place and then blow up the thing. What do they care? Is it a countermeasures thing or is the whole blowup about the military technology leak and not the actual military technology that was leaked?
