OK, first thoughts. I see four pairs SS-N-12 launchers seemingly intact. Major damage seems to be in way of the midships deckhouse with AK-630 CIWS. That's a fair amount of cookoff if the ammo catches. The black patches seem to be smoke from shattered windows. 1/n
Regarding The Slanty Ship. Landing ships usually have wing compartments either side of the vehicle deck, allowing access, space for troop accommodation etc. This can cause a severe list from relatively minor damage, due to the asymmetric flooding. 1/n
So, pending further information, I'm not very stressed over DIAMOND using her 30mm to down drones. Palletised 30mm has been provided to Ukraine as a counter to Shaheed. Darkened ship could be near invisible to drone operators so DIAMOND may have been able to... 1/n
Sometimes I remember that NRO launched the worlds largest spy satellite - with an estimated dish diameter of 100-120m - and straight up parked it next to an Arabic telecoms satellite to eavesdrop on phone calls from 36000km away and there’s something utterly hilarious about it.
If you're a sci-fi spaceship designer, you're legally required to use only these three design templates for your spaceship guns.
Sorry, but that's the law, I guess, if even hard-sci-fi artists do that.
A reminder that students do not always do what you expect. After being instructed that may only use a 190kWe solid-state nuclear reactor, the students realsed we hadn't specified *how many* and so fitted five of them :D
Slanty ship analysis. Assuming watertight compartments A-M as shown - dotted line is where think the vic deck narrows. I've assumed the ballast tanks are divided into wing tanks and a centre tank. A lot of assumptions and a crude hullform but intact seems reasonable so OK... 1/n
Lead. Lead? LEAD. This claimed room temperature superconductor is based on LEAD. All this research with wierd things like yttrium or lanthanum and it might be LEAD.
The engagement radars for SA-N-4 and SA-N-6 both appear to be stowed. Given that the fire monitors seem to have been abandoned running I think it unlikely the radar were carefully stowed after the hit: This would lend credence to the story the crew were distracted by a UAV 4/n
The UAV would be an easy target so they may have been watching to see what it did. The distraction here is conceptual - it's not that they are looking the wrong way, it's that they are focussed on the wrong *type* of threat. This has happened to others before. 5/n
An interesting aspect of nuclear propulsion was that it made atmosphere control hard in odd ways. As the boat was no longer ventilated regularly, previously unnoticed contaminants would build up. Examples in the literature include 1/2
(NYTimes Mar 20, 1953)
- 23 volunteers...have been sealed in the hull of the Fleet submarine HADDOCK since January 19th, in an effort to find out how much CO2 can be tolerated...they have lived in a machine-controlled atmosphere...is vital in the design of atom-driven subs.
Shahed - which in most versions has no targeting sensors - being called a drone whilst Tomahawk Block IV - which can loiter and image targets - is still a missile shows just how nonsensical the term “drone” has become. Does it really just mean “trendy in defence circles”?
"1" marks lower hull damage that may be the result of a strike or the subsequent internal fire. "2" marks what appears to be a destroyed deckhouse (IIRC these ships have some aluminium in the deckhouses). However 2 could be due to cook-off of the AK-630 mag. Or a missile hit.
...and the presence of paint over most of the hull (on the side we can see, anyway) makes a widespread high-temperature fire unlikely. *Based on this one photograph only*. I would be *very* surprised if internal furnishings met modern fire resistance standards. 2/2
Discolouration on the hull at the waterline may be; side shell blown out by internal explosion; the hole where the missile went in; paint peeling due to the heat of the fire. I don't know what delay Neptune's fuze has, so it could have exploded deep in the ship. 2/n
Liferafts and ships' boats seem to have been launched - note the rather distinctive boat crane is deployed. So a large proportion of the crew may have gotten off. However it is clear smoke has spread throughout the after 1/2 of the ship. And that stuff is nasty. 3/n
Watching a USN video on 1980s CV operations that claims “No aircraft designed for land operations has ever been converted for carrier duty”. SEAFIRE HAS ENTERED THE CHAT
This raises questions about what damage control state the ship was in - I suspect low, as others have pointed out there was not much expectation of attack and WTDs are a pain to constantly operate. Smoke boundaries do not appear to have worked. 9/n
What's surprising is how far the smoke has spread. Whilst he seems to have been largely abandoned at this point, the bulk of the smoke is coming from amidships but again we see soot on the hull. This implies a rapid spread of smoke from fires subsequently extinguished 8/n
Another image here. Note the "knuckle" running the length of the hull. It looks to be still nearly horizontal, so if there is a trim angle, it is small. Flooding (at the point of this photo) may have been confined to amidships, but submergence of the deck aft is imminent 7/n
Of course we have to remember that a hit in the forward GT room is also close to some of the main command spaces, so co-ordinating the "internal battle" would have been very difficult 10/10 (for now)
At last! A photograph has surfaced, providing undeniable evidence of four 533mm torpedo tubes for Atlas SEAHAKE Mod4 HWT torpedoes on
#EgyptianNavy
MEKO A-200EN frigates. Remarkably, this marks the second instance of a modern frigate being equipped with 533mm torpedo launchers,
US Navy demonstrated re-arming vertical launch system aboard destroyer USS Spruance (DDG-111) in San Diego from Oct. 4-7. It is the first time US Navy has tested VLS reloading from offshore support vessel, using Military Sealift Command fleet experimentation ship MV Ocean Valor.
A point on hull shape. I don't see any evidence of hull overall hull sagging at this point. Straight lines added in MS Paint. The visible smoke fits with an internal fire involving a substantial amount of non-fire retardant, smoke generating materials, and 1/2
... downflooding would be limited unless the tank top itself was holed. This figure doesn't show us a transverse section, of course, so we don't know what was in the wing compartments (if anything). But currently this looks like a "mission kill" only - should be repairable 6/n
Of course I am a member of the Church of LMM so I still reckon these should be fitted. To borrrow a line from Mike Watt: "That my friend will mash up the engine block of a Fiat Uno nooooo problem" 3/n
Copier ink (solvent is volatile & evaporates) and radon. Nautilus found the cure were getting higher than expected radiation exposure, not from reactor but rather radon from luminous paint used all over the place. As with space, propulsion is “easy” compared to life support! 2/2
Whilst the USVs are credited with a reasonable size warhead (200-400kg depending on source) they can't put it in a very effective place - it will explode outside the target, and above the waterline - so holing a single compartment might be all you can expect 2/n
Position herself to intercept without being at direct threat. In which case the 30mm makes a lot of sense as it should have a high Pk against this target, and a lot of stowed kills in the deep magazine. Save the Aster for more stressing/urgent/threatening targets 2/n

we have this profile. OK, so the diesel generators (item 8) are in the superstructure over the main machinery spaces. Beneath the tank deck (19) are ballast (20) and fresh water (21) tanks - SO... 5/n
It is 1999. I am listening to the Ghost in the Shell soundtrack on Winamp and designing ships. It is 2024. I am listening to the Ghost in the Shell soundtrack on Winamp and designing ships.
Reading about the modernised T-55s being donated to Ukraine led me to learn of the SPOT-55, a Thunderbirds-esque fire fighting variant produced by Slovakia (photos from Reddit)
... unless you hit near a bulkhead of course. The video shows a hit under the superstructure, but forward of the funnel. I don't have a layout for the Ropucha-class, but it's probably forward of the main machinery spaces. There *may* be a generator space in this vicinity 3/n
Finishing up the Advanced Marine Vehicles lecture for my undergrads and I always use this image to illustrate that, with enough power, "anything will plane".
This is an interesting discussion I have with my students at the start of the course. We have to differentiate between complicated (a lot of parts) and complex (a lot of interactions and emergent properties). Many commercial ships are more complicated than naval vessels but.. 1/n
Why do people keep telling me that commercial ships are less complex and sophisticated than warships?
I think we can all agree that ships are all awesome!
But that's speculation - an overhead shot of the funnel would help figure it out (or a layout! :D). Downflooding will probably have occured however so the extent of the damage might be a single wing compartment and the hull beneath it flooded. 4/end?
I want to be sad but all I can think of is the possibility of a band of piratical raccoon submariners, sailing the high seas, searching for gold doubloons. And trash.
Podvodnaya Lodka B-427 Scorpion - one of the two US submarine museums that are rotting away and have secured access to the public. It apparently has a raccoon infestation. Sigh....

Since there was a thread about accommodations on USN SSBNs, here's the deck plan for the crew spaces on the first generation French SSBN, Le Redoubtable. Along with a couple of interior shots of the classy '70s decor!
For those wondering what a rocket landing ship was and why it was so insane; they carried large numbers of unguided rockets and would be used to saturate enemy positions prior to a beach landing. Photos from Wikipedia LSM(R) pages.
OK. Some preliminary results. Any more detailed than this is work stuff and probably won't be put here. This is a very quick model using the published profile. Assuming a missile hit in the forward gas turbine room which floods that and the spaces either side 1/n
This. On a night bus home some dude boxed me into a corner and the chap in the seat behind us did a frankly exceptional job of engaging and distracting him with this type of “banter”. Wish I could have thanked him.
One odd thing about NSM is that it's launched belly-up - I presume because flat top makes integration on a launch rail easier. Another odd thing is that the whole nose rotates to keep the imaging IR seeker horizon-stabilised - enabling a high degree of target discrimination.
It’s like the Burns Slant Drilling of intelligence gathering. Either that or the eavesdropping equivalent of children yelling “I’m not touching you” whilst poking their sibling.
Kh-35 is "Uran" (Uranus) the Russian predecessor to Neptun(e). I believe these test shots may have been unarmed, but it illustrates the damage that will be done by the kinetic energy alone.
For a properly bonkers carrier, why not add a modern 18 inch gun battery? A 1970s proposal by one Philbin, former gunnery officer (CAN YOU TELL?!) in the USN. "A Proposal for a New British Capital Ship"
This era of Russian hangar design was fascinating from a mechanical design point of view, but very overcomplicated. One example of the reality (frequent (excess?) complexity in Soviet design) against what I call "the AK-47 myth" (the myth that Soviet design was always simple) 1/2
Some unusual helicopter hangars in service with

ships:
- Photos 1 & 2: The below deck hangar of a Kirov-class (pr. 1144.2) nuclear powered battlecruiser can accommodate three helicopters.
- Photos 3 & 4: The Udaloy-class (pr. 1155) destroyers have a twin half-below
Since we are talling about SWATHs we can't forget this brilliantly bonkers concept from USNI Proceedings. This is the relatively conventional version. The air defence variant had a circular plan view, enforced by the track of the BETATRON ACCELERATOR PARTICLE BEAM WEAPON.
Younger naval watchers might not quite get just how Big Of A Deal Moskvas sinking is to us oldies. That ship was a major symbol of the late Cold War at sea. The class was seen to be a low-risk alternative to Kirov, but an absolute unit nonetheless. An actual end of an era.
