Also, anyone got basic stats on the SM-3 Blk IIA (other than diameter, which is 21 inches apparently hehe) ?

quote:

Any chance you could add the SM-3 Block II/IIA? They would add an interesting dynamic for some near-future PRC/USN scenarios, as most Chinese SAR satellites are inside the engagement envelope for the Block II/IIA interceptors.

Guidance should be the same as the SM-3 Block IB (already in game).
Target speed should probably be increased over the Block IB to at least 15000 kts or set to unlimited like the ALMV.
I have found no info on minimum target altitude, but I would assume it is the same as the Block IB
Max target altitude should be at least 1400000 meters (Lower estimate of max altitude for Block II based on higher burnout speed)
Missile velocity for the upper band should be 8750 kts, or 4.5 km/s, which is the lower estimate for the burnout speed of the new 21" booster
Ph should be 95%, consistent with other ASATs/ABM systems in game.
Range should probably be on the order of 500 NM (again, hard to find specific numbers)
Year should either be 2015 (First flight test) or 2016-2017 (Likely IOC). This would mean that the 2015 AEGIS BMD ships should receive the ability to load the Block II's in their VLS tubes. (They are entries 2342, 2343 and 2344 in DB3K)

On the topic of ASATs, the F-15 ASAT (Entry 1994) shouldn't have it's gun, as the ammunition drum was removed to provide cooling for the ALMV. Only a wiki source on this one: http://en.wikipedia.org/wiki/ASM-135_ASAT#Design

Well, if you pause quickly enough before the exhaust obscures it, you can see the launcher in the clip I edited into the original post. Looks like it can only hold one missile in each launcher.

Continuing the Iran weapons:

Ya Zahra-3 (YZ-3) SAM-
Most detailed link on stats. The claim is of a mix of semi-HQ-7/Crotale and Skyguard radar.

There was also the claim of mass-production. here, with more pictures.

However, I remain decidedly skeptical as to its deployment, since the announcement was two years ago and I haven't seen any more news of it (besides propaganda parades and this far too uncritical piece) since then. Closest "good" source I can find is this

Mersad SAM-
Slightly more sources beyond propaganda on this. A highly unreliable blog claims it operational (as opposed to just "unveiled", or "in production".)

However, The Arkenstone treats it as more credible, as does APA. Still no obvious source, and neither is truly official.

Arkenstone claims 250 km range for its phased array search radar, but it is based on a propaganda report.

Can find an overview of Iran's missiles from CSIS here.

[ADDED HAAWC DB v440]

The P-8A Increment 2 is scheduled to become operational by 2016, and with Increment 2 comes the MAC system (SSQ-125 and SSQ-101) and HAAWC (High Altitude ASW Weapons Concept), a Mk.54 Torpedo fitted with a wing kit that allows the Mk.54 to be deployed from long ranges.

From : navytimes.com/article/20140127/NEWS04/301270042/Troubled-P-8A-Poseidon-enters-full-production

"The next program milestone is Increment 2, slated for 2016, will include multi-static active coherent acoustics, automated identification system, and high-altitude anti-submarine weapons, according to a NAVAIR news release."

From : militaryaerospace.com/articles/2013/04/Boeing-flying-torpedo.html

"Airborne weapons experts at the Boeing Co. got the go-ahead Wednesday to start building add-on kits for the U.S. Navy Mark 54 lightweight torpedo that will enable the weapon to glide through the air from altitudes as high as 30,000 feet and enable the Boeing P-8A Poseidon maritime patrol jet to attack enemy submarines from long ranges."

The HAAWC is said to have a JDAM-ER style wingkit attached, so considering the JDAM-ER in the DB has a 40 mile range, the HAAWC will probably have something close to this.



From : defenseindustrydaily.com/longshot-a-swooping-haawc-for-torpedos-03340/

" "what if we could attach a JDAM-ER style glide kit with GPS guidance to a lightweight torpedo, launch from high altitude, then let the kit maneuver it into attack position and release it near sea level instead?" "

The MAC, or Multi-static Active Coherent, is a system that uses an active source sonobuoy (AN/SSQ-125) and multiple ADAR receiver sonobuoys (AN/SSQ-101). The DB has the the SSQ-125 and SSQ-101, but how do you (The developers) model a multi-static system like this in Command?. Also, the SSQ-125 is said to have improved performance over the SSQ-110 IEER (also in the DB, but with the same range as the SSQ-125)

From : dote.osd.mil/pub/reports/FY2012/pdf/navy/2012macsystem.pdf

"The MAC system is an active sonar system composed of two types of buoys (source and receiver) and an acoustic processing software suite."

"MAC is an upgrade to the Navy’s current Improved Extended Echo Ranging (IEER) system, which employs non-coherent sources to produce loud sounds that reflect off submarine targets; these echoes are then detected by receiver buoys. MAC employs the same receiver buoys, but uses new coherent source buoys that enables multiple pings, optimized waveforms, and various ping durations, none of which the legacy IEER system provided."

From : seapowermagazine.org/stories/20150414-p8-acoustic.html

"MAC, an evolution of Improved Extended Echo Ranging used on the SSQ-110 sonobuoy, uses the SSQ-125 sonobuoy. The SSQ-125 generates loud sounds electronically rather than using small explosive charges to generate sound as in the SSQ-110. The long-range echoes from a target are intercepted by the sonobuoy and relayed to the aircraft’s sensor system."

The Strales 76mm system with DART guided ammunition is the only weapon system in the world which can ensure high level performance (at a lower cost than dedicated anti-missile systems) in the engagement of manouevring supersonic missiles with high lateral g force. The system is very effective also in the engagement of fast manouevring little boats.

Thanks! Does anyone have a photo of the a/c actually carrying the YJ-12 missile? That would be very (very very!) helpful. I have a sneaking suspicion that the weapon is not nearly as operational as some sources would want us to believe :)

Wonderful, thanks!

How many missiles do you think the bomber an carry? Is the weapon too heavy for carrying 4 of these?

Hard to say, because the PLAAF rarely carried full load during excercises.

And there are no reliable estimates for the YJ-12's weight, but pretty good ones for its dimensions (due to that first H-6G photo).

I'm a bit cautious about the 3 ton weight of that missile and the dimensions quoted in the DB, as it should be actually smaller than the 2.2-2.5 ton air-launched BrahMos ( 6,3 meters long, diameter below 756mm YJ-12 vs 8.4 m length, Diameter 670mm PJ-10 BrahMos).

I'd estimate the weight to be somehwat lighter than the air-launched Brahmos, and hence the H-6G would potentially be able to load four of them, just as it was able to load four pretty big and heavy 2.4 tonne class KD-63 LACMs.

Here's another BUMP for the experts out there

I need detailed stats on the Norwegian N 51 Borgen controlled minefield tender. All I've found so far are two black-and-white photos. No stats at all.

Any help on this would be greatly appreciated! Thanks!

Janes Fighting Ships says...

N 51 Borgen

Operational Dates: 1961-??? (not sure when she was decomissioned; she is listed in the 91-92 JFS but not in the 04-05 JFS)

Displacement: 282 tons standard

Dimensions: 31.2 m x 8 m. x 3.4 m

Main machinery: 2 General Motors 3-71 diesels; 660 bhp; 2 Voith-Scheider propellers

Speed: 9 knots

Range: ??? (nothing listed, but a slightly larger minesweeper, ex-Adjutant class, 384 tons full load, with similar GM engines, lists a speed of 13.5 knots and a range of 2,500 miles at 10 knots, so maybe something like 2,000 miles at 8 knots might be plausible for the Borgen???)

Guns: 1 Rheinmetall 20mm (appears in picture in 89-90 JFS to be on the bow)

Mines: 2 rails

Radar: Navigation; I-band

Note: Has two derricks used for mine placement

I hope this helps.

New info on the LCS Anti-submarine module

The ASW Module for LCS will include the new CAPTAS-4 Variable Depth Sonar from Thales

From : https://www.thalesgroup.com/en/worldwide/defence/naval-forces/underwater-warfare/anti-submarine-warfare-surface-ships/captas-2-variable-depth-sonar

"CAPTAS-4 selected by the US Navy for ADM contract on LCS programme."

CAPTAS-4 Information - https://www.thalesgroup.com/sites/default/files/asset/document/thales_captas-4.pdf

From : http://news.usni.org/2015/07/30/lcs-anti-sub-warfare-package-too-heavy-3-contracts-issued-for-weight-reduction-study

"The mission package includes a Variable-Depth Sonar – the Navy chose the Thales UK Sonar 2087, the same VDS used on the Royal Navy’s Type 23 frigate "

The initial deployment date was set a 2016 but because of sequestration and weight problems this will most likely get pushed back to 2017

http://docs.house.gov/meetings/AS/AS00/20130918/101291/HHRG-113-AS00-Wstate-GreenertUSNJ-20130918.pdf

"An ASW mission package that will be fielded on LCS in 2016, which increases surface ship ASW capacity and delivers improved capability by using a MFTA in combination with a variable depth sonar (VDS). "

So far I can't find the official US military designation for it yet.

FIXED DB v 440
The Tu-142MZ Bear F Mod.4 added the upgrade Korshun-KN-N surface search radar and the NK-12MP engines

quote:

3.4.2 Amethyst – a Russian example
Soviet scientists researched LIDAR technology parallel to their Western counterparts, and
managed to place a system, although fragile, on some of their Bear F Mod 4 ASW aircraft.
The system is called “Amethyst”, and uses a blue-green CO 2 laser. It scans from side to side
as the aircraft moves forward covering a 100m wide swath. The pilot must maintain constant
altitude and speed (100m altitude, 100m/sec = 200 knots speed), and the system has to be shut
down whenever the aircraft turns.

Each line in the display represents one scan, and deviates up and down to indicate
range, in effect depth. The lines are scaled one meter apart, and very high projections or deep
troughs extend over adjacent lines creating a shadow effect. The back-and-forth scan forms a
green line on a standard Russian 525-line screen, measuring 20x25 cm, with a frame rate of
100Hz. Because the screen is relatively short, the image is compressed vertically, and is
somewhat distorted toward the sides because the beam slants so deeply there. The system is
calibrated to 50m depth, but it is said to be ineffective below 30m. The system requires
interpretation by the operator, which in many cases can be difficult. Some operators never
learn to interpret, but others do in a relatively short amount of time.

The limitations on aircraft motion suggest that the system is mechanically range-gated,
probably by a disk rotating in front of the receiver. The sensitivity of the receiver dictates that
the aircraft must fly steady with no turns, as the change in angles and ranges to the sea surface
most likely will burn out the receiving equipment. The system processes only one pulse at a
time, and hence the strict limitations to aircraft speed as well. If the aircraft moves too
quickly, part of one line is inserted into the next (Friedman 1997:663).
Due to the strict limitations and the fact that the system has been installed on a Bear F
and not the Russian primary ASW Aircraft, Il-38 May, one can speculate that the Russian
armed forces has not pursued the technology further after the implementation of the
Amethyst.
