A good comparisson between the Type 093B SSGN left (or "093G") and the Type 093 SSN right.
The 093B SSGN looks considerably fatter and slightly bigger/longer than its predecessor... Wasnt there the technical notion that bigger nuclear submarines are quiter, due to having more space for internal noise dampening?
Some leakers say that the 093B could have 1000 tonnes more displacement than the 7000 tonne standard 093/A.

Look at the stern section of right 093, I think it submerge a little bit more than the left one, so to make it looks a bit smaller.

Tomahawk Missiles Will Get Twice As Deadly By Blowing Up Their Own Fuel
http://www.popularmechanics.com/military/weapons/news/a18994/tomahawk-missiles-fuel-air-explosion/
This is actually somewhat interesting, because the closer to the target you fire the missile, the more damage it does?

The missile's solid fuel is a propellant, not a dynamite. If it have to be a part of the damage, I believe it need to be penetrated into the ship hull/building, and caused the fuel-air effect of explosion when warhead is detonated. The external combustion/detonation will be just as weak as the secondary damage.
Problem is, can Tomahawk withstand huge amount of kinetic impact to keep all the fuel intact until the ENTIRE missile is inside the target, and detonate as planned? If the target is a heavily protected/armored, such chance of destruction is very less likely happens. Except the missile is smart enough to drill through a window, or hanger gate to make such of havoc.
In that case, CMANO also need to simulate the missile's actual penetration of target, and the remaining fuel of missile to summarize the total damage.

Dysta,
If you'd actually read the article, you'd know that Tomahawks are powered by small jet engines, which burn JP-10, a very energy-dense liquid fuel. And the article addresses the questions you asked.
Furthermore, even without modifications, TLAMs
burn quite well when they hit their targets.

Wow. Liquid fuel and Turbojet? That'd be more powerful and volatile than the solid based counterpart.
But still, if the remaining fuel isn't inside the target and being combusted, then the FAE is too weak at outdoor, and only the warhead to deliver the raw damage.

Dysta, there was never a solid fuel counterpart- the tomahawk has always been an air-breather. The VLS, and ground based varients do use a solid fuel booster to launch and orient towards the target, but after that the booster motor falls away and the weapon deploys its control surfaces and intake and continues down range.

Haha, I said counterpart means a general design of missiles after the Cold War. Since they are built to be smaller and fly further with more fuel mass and lower air frictions, and more rely on kinetic kills than bigger warheads.
Tomahawk is always liquid fueled, as I get that, that is why I was little confused of how they can deliver extra damages.

The FAE incorporation into the Tomahawk is interesting. Here's a video of the kind of shock or overpressure damage a BLU-96B FAE bomb does when it goes off next to a house.

WASHINGTON, Jan. 15 (UPI) -- Raytheon's new Excalibur N5 projectile was fired from a 5-inch naval gun during a flight test at Yuma Proving Ground in Arizona.
The Excalibur N5 is a 5-inch variant of Raytheon's Excalibur extended range precision projectile. The projectile is currently in use by the U.S. Army and U.S. Marine Corps, in addition to other armed forces. The company expects the N5 variant will triple the effective range of naval gun munitions currently in use, while maintaining the same accuracy.
The new sea-based projectile is designed to be used for naval surface fire support, anti-surface warfare, and engaging fast attack craft.

"Burning vapor produces an exhaust like a jet engine, and when the flame front reached the trees, it accelerated to high speed. The irregular branches and twigs made the smooth flow turbulent, mixing the vapor cloud with air so it burned far more rapidly and with much greater force."
Science is so fracking cool!!!

I kinda get that, considering the Abram with JP8 fuel and obvious exposure of ammo compartment, catching military machines on fire is already becomes typical in modern warfare. Moreover the turbine-powered ships; It can combust diesel, but sometimes they use kerosene and biofuel for the sake of versatility during the resupply, and these things are dangerously hot if being lit.
But then I think again, most of the losses are from explosives. Fuel-air explosion is not only a military hype, but also a hidden nightmare from several missiles, and is happening too.

Old news, but interesting that there seems to be some stats for the new Yu-11 light weight torpedo on Wikipedia, based on Jane's and leaks on the Chinese internet:
https://en.wikipedia.org/wiki/Yu-7_torpedo
Yu-11[edit]
Yu-11 is the follow on of Yu-7 powered by the same Otto fuel II and developed by the same 705th Institute.[2] Development first begun in 2002 and the torpedo finally entered service more than a decade later in 2015,[3] with its existence revealed by CCTV-7 in the same year when the TV station ran a footage of Chinese naval war games in July 2015, showing a new light weight torpedo (LWT) launched from a surface warship.[2] The new Chinese LWT is obviously longer than its predecessor Yu-7 and many Chinese military enthusiasts have postulated that the extended section houses additional fuel to increase the speed and range, but some western analysts such as Jane's Information Group have also postulated that the extended section might house homing and data processing subsystems.[4]
The most significant improvement of Yu-11 over its predecessor Yu-7 is in the propulsion system, with steam generated propels the torpedo in a closed Rankine cycle,[2] thus enabling Yu-11 to have greater operating depth, rumored to be over six hundred meters. The contra-rotating propellers of Yu-7 is replaced by a pump-jet,[2][4] making China the fourth nation in the world to master the technology of adopting pump-jet for torpedoes.[2] Another benefit of adopting pump-jet is the significant reduction of noise radiated by the torpedo, thus greatly increasing the difficulty to detect the approaching torpedo.[4] Specification:[2]
Speed: 50 kt max
Range: 11 km @ 50 kt, 30 km @ 26 kt
Diameter: 324 mm
Based on the photos that I've posted back in post #156, it seems like the Yu-11 is at least confirmed to be deployed on the newer Chinese surface combattants, such as the 054A FFG:
fb.asp?m=3913967
But presumably, the ASW helos and MPAs will all receive a "K" ("Kong" = "Air-dropped") variant as well, since they are still the mainstay ASW assets of the PLAN who are expected to use any LWTs in combat.

SNA 2016: Kongsberg Showcasing LCS, DDG 51 and LPD 17 Fitted With Naval Strike Missile
At the Surface Navy Association's (SNA) National Symposium currently held near Washington DC, Norwegian company Kongsberg is showcasing the Freedom and Independence variant Littoral Combat Ships (LCS), an Arleigh Burke class Destroyer (DDG 51) and a San Antonio class Landing Platform Dock (LPD 17) each fitted with eight Naval Strike Missiles (NSM).
...
"Kongsberg is showing what the distributed lethality concept could look like on a number of U.S. Navy vessels" Hans Kongelf, Vice President of Missile Systems at Kongsberg, told us during SNA 2016.
The distributed lethality concept was introduced (and is being advocated) by Vice Admiral Thomas Rowden, the Commander of the U.S. Navy's surface forces. It can be summarized by fitting more weapons on more vessels in order to "deceive the enemy, target the enemy, and destroy the enemy".

"ORKA's first flight test took place in December 2015 and was fin stabilized only (no canards) to check aerodynamic stability" said Charlie McCullough, Director of business development, maritime weapons at BAE Systems. McCullough explained that maneuvering tests with canards would take place this summer.
ORKA follows a U.S. Navy requirement to give more lethality to Littoral Combat Ships, especially against swarming types of attacks.

Fuel-air explosion is not only a military hype, but also a hidden nightmare from several missiles, and is happening too.
The most recent example in this video at the second footage. The strike is not happening at indoor, and not an instanteous FAE effect, but the fuel ignition when being hit is very scary (either missile's own fuel, or vehicle fuel and/or ammo propellants) :

And these are Iraqi CH-4 land strike, looks like they aren't going to stop playing those new toys for a while.

Second semi-submersible MLP ship under construction at Tianjin.
Assessed L-200m, W-35m.
Space available 130m X 33m.
GE DOI 9/13/15
Looks like the PLAN is very satisfied with the design. Gotta need at least four of them to transport the Zubr Hovercrafts that are in service now. And more in the future for other purposes.

About SAT photos, the recent SAT picture also shows the completed state of Type 091 AOE before the launch:
And the launched side view, which is still fitting out:
I hardly reference the dimension of it since there's no known-object beside AOE for measurement, and also, many military analyses and amateurs are still debating its maximum displacement, in between 45,000-55,000 metric tones.
