Thanks, Enrique. Much appreciated.

3943 CVH Izumo (I think a not yet overhauled entry, but to be deployed in the hot Indian Ocean and South China seas from May to July 2017) has only basic sensors, Navigation Radar, OPS-28 and FCS-3 PAR.

Sensors should be apparently OPS-20, OPS-28, OPS-50, OQS-23? (No data on OQS-23, in my notes listed as with a OQS-4 previously. Also in my notes is also referenced a OQR-2 TACTASS/SQR-19A(V), but I don't see now the reference, but apparently is not in Izumo, see below).

 

OPS-50 is employed by 16/18DDH Hyuga, 19/20/21DD Akizuki and 22/24DDH Izumo.

Is a big four faces AESA C-Band search radar HF/AS/SS, 200 nm range.

 

FCS-3 is a smaller four faces AESA X-Band fire control radar, is employed by 16/18DDH Hyuga.

 

FCS-3A, a derivative, is employed by 19/20/21DD Akizuki, adds control for 127mm gun (air and sea targets), previously is employed only for ESSM in Hyuga-class.

The initial question was, what's an OQS-23? But the answer is a little long ... (to be edited and processed with more time):

 

Sonars from the Japanese Wikipedia entry:

https://ja.wikipedia.org/wiki/%E6%B5%B7%E4%B8%8A%E8%87%AA%E8%A1%9B%E9%9A%8A%E3%81%AE%E3%82%BD%E3%83%8A%E3%83%BC#OQQ-21

 

JMSDF second generation sonar was SQS-23

OQS-3 is equivalent to SQS-23

At the Maritime Self-Defense Force, while installing the above-mentioned American-made machines and their licensed production machines, they were also searching for domestic production. At the time of the Showa 37 planned ship, the state-of-the-art AN / SQS-23 manufactured by the United States was equiped, and a domestically produced OQS-3 with nearly equivalent performance was developed and equipped. It evolved into OQS-101 and was updated by OQS-4.

 

OQS-3

In the Maritime Self - Defense Force, we first developed T - 1 which is a searchlight sonar using nickel magnetostrictive material, and T - 2 which is a scanning and sonar using an alfero magnetostrictive material, but both are inadequate in terms of performance Since it was there, it did not lead to equipping. From this, from the first half of the 1950s, an attempt was made to commercialize the practical sonar ten years later, and it was prototyped as T-3 from 1954 to 1954. Meanwhile, the material of AN / SQS-23 which was developed a little ahead of time was provided, and it was utilized to determine the oscillation frequency etc. The prototype was completed in March 1959 and was mounted on the escort ship "Wakaba", and from spring of 1963 it shifted to marine technology test. Although considerable trouble occurred in the examination, it was overcome by the public and private unity efforts, and eventually it was detected under the same conditions as AN / SQS-23. After the practical test from March 1943, it was formulated in 1964 and it is called the 66 type search trust OQS-3 [10]. Started to be mounted from the planned ship in 1964, and finally 23 were equipped with [11]. Note that OQS-3 is NEC, OQS-3A is handled by Hitachi

In this machine, the electrostrictive transducer by barium titanate is adopted as the transducer. As for the reception format, the conventional sonar used scanning reception, whereas the stand-by reception was adopted in this unit, so signal energy can be positively integrated, and the SN ratio is large It was improved [12]. In addition, the AN / SQS-23 in the United States was aimed at a frequency of 4.5 to 5.5 kilohertz and a detection distance of 9,100 meters. The TR - 208 transmitter was housed in a large ship 's neck dome, and 432 transducers using barium titanate electrostrictive transducers were arranged in a cylindrical shape as 48 staves

OQS-101, comparable to SQS-26

Low frequency active / passive sonar developed in parallel with OQS-3. It is said to be comparable to the American AN / SQS-26 developed and deployed a little ahead, and it also corresponds to the connection with the OYQ-101 anti-submarine information system (ASW Direction System: ASWDS) [13] .
Development began as a long distance discovery device T-101, and research trial production was conducted from FY 1979 to FY 1973, and technical tests were conducted in FY 1980 and FY 1940. Receiving the results, we tried again from 1947 to 1943, and carried out a technical test in 1964. In Showa 45 and 46, a practical test was carried out by carrying out a repair to install a prototype at the bow of the escort ship "Ariake" of the practical test team (present development team). Sonar is a large-sized machine with a diameter of 5 meters, which, due to its mounting, increased in size to 5.5 meters in total length and 230 tons in drainage volume. Also, in order to cover its large power consumption, it was a very large renovation, including an output of 225 kilowatts of diesel generator, so a year was spent on construction. After that, after the performance improvement test, it was formulated as 75 type search trust OQS-101 in FY 1972

This machine is the first sonor in Japan to support long distance detection by convergence zone (CZ), submarine recoil (bottom / bounce, BB). For this reason, at the beginning when the T-101 was prototyped, although a fluctuation correction device was added to reduce the influence of ship's rolling, it turned out that the mechanical noise of the device was an obstacle to sonar detection Then it was removed. In addition, although the deaerator was installed in the sonar dome, the effect was not recognized even though there was concern about the influence of the cavitation accompanying the vibration at the low frequency oscillation [14]. In operation and signal processing, new technologies such as sector scan indicator (SSI), adoption of LFM (linear frequency modulation) signal and correlation processing, automatic gain control (AGC), TDI (Target Doppler Indicator) Was done

Although this machine had considerable high performance, it is a considerable weight as a price to compensate for it, and if it is mounted on a 3,000-ton class escort ship, a heavy-weight equipment occupying about 5% of the reference drainage is equipped on the bow Special consideration was required to do so. For this reason, the equipment ship was supposed to be only the Shirigayan type escort ship (50 DDH) [14], the equipment at a later date to the Haruna type (43 DDH) which was initially considered was not eventually realized [16]. Equipment method is similar to OQS-3 as a bow-equipped equipment (Bow · sonar)

Users: Shirane-class 50/51DDH

 

OQS-4

Low frequency sonar such as AN / SQS - 23 and 66 type searching OQS - 3 has been adopted in the anti - submarine destroyer (DDK) and multi - purpose escort ship (DDA) since the Second Defense Potential Development Plan. Although it had a detection distance that can demonstrate Max Range of Asrock, in particular in the waters around Japan, from the circumstances of the marine environment, such long distance detection is few in fact, at medium range (about several thousand yards) The detection and attack of the center was mainly. In addition, these sonars can expect long-distance detection because of low frequency, and detection is unstable, too. As a sonar of 52DD, Maritime staff staff members are Oliver Hazard Perry-class missiles of the US Navy It was a candidate for AN / SQS-56 of medium frequency (7.5 kilohertz class) adopted in frigate.

However, at that time, the development of OQS-101, which is a revolutionary low-frequency sonar in Japan, has just been completed, and there are problems with defense equipment to shift to overseas products with only two of them It was thought. Also, if we utilize the domestic technology established and accumulated through the development of OQS-101, it was estimated that it can be produced without new development by reducing the risk associated with the introduction of the new model, so AN / SQS-56 It was decided not to import but this one to be selected. This was developed by OQS-4.

Partial digitization was underway at OQS - 101, but it was expanded significantly with this machine. However, it was not as much as OQS - 102 or OQS - 5 which was completely digitized, but it was transitional. By making the major components semiconductive, miniaturization and weight saving are achieved, and by making the elements of the transducer independent type, it is only necessary to replace the element only when the element breaks down, and improvement of maintainability is also improved It was taken. In addition, as a benefit of digitization, improvement of signal processing technology and increase of processed signal quantity were introduced, addition of display format was added, and improvement of operability / detectability was attempted [17]. In addition, the last ship of the shirt type (61 DD) was concatenated with the OYQ - 101 anti - submarine information processing device (ASWDS)

In OQS-4, OQS-3 and OQS-101 were equipped with ship-bottom equipment (Hull / Dome), except for racket type, whereas OQS-3 and OQS-101 were bow- There. Hull · dome was made of all steel as usual with 52DD mounted OQS - 4, but in OQS - 4A with 58 DD installed, it was made into rubber dome and rubber dome became standard in later sonar for escort ship

Third Generation JMSDF Sonar OQS-X

At the 5th laboratory of the Technical Research Headquarters, element research such as researching active sonar target classification equipment was repeated from 1978 (Showa 53) degree to 1982 (Showa 57 years). Based on this, we began to develop a sonar system (OQS-X) that integrates multiple sonars such as active sonar and TACTASS and performs signal processing according to the ocean conditions and application, thereby enabling the operation to be optimized It was done [18].
Technical tests were conducted from 1984 (Showa 59) degrees to 1986 (1984) degrees, from 1986 (1986) to 1987 (1982), technical examination was conducted, 1988 (1983 ) Degree to 1989 (Heisei era) year, the practical tests carried on the special ship 'Akitsuki' were carried out. Although OQS-X was not put to practical use, signal processing / classification technology, common processing technology of signal processing, rubber sonar dome, etc. were said to be adopted for OQS-102 and OQS-5 sonar

 

OQS-102 (Equivalent to SQS-53C)

It is an evolved type of OQS-101, and it supports the connection with the OYQ-102 anti-submarine information processing device (ASWCS). It is said to be roughly equivalent to AN / SQS-53C in the United States.

Users:

Konjac type missile destroyer (63/02/03/05 DDG)

 

OQS-5

Low frequency active sonar which becomes the successor of OQS-4. It supports the connection with OYQ-103 anti-submarine information processing device (ASWCS). In Takanami type it developed to OQS - 5 - 1

Users:

Murasame type general purpose escort ship (03 ~ 09 DD)
Takanami type general purpose escort ship (10 ~ 13 DD)

 

Fourth Generation JMSDF Sonar (OQS-XX)

We conducted research prototypes from 1987 (1986) to 1988 (1983) in the departmental research, 1989 (1989) to 1990 (Heisei 2), 1990 (Heisei 2) and Based on the in-house examination in 1992 (Heisei 1992), prototypes were made from 1992 (Heisei era 1992) to 1994 (Heisei era), and the prototype OQS-XX is a test ship "Asuka" (04 ASE ) Was installed. From 1995 (Heisei 7) to 1996 (Heisei 8), a technical test was conducted, 1997 (1997) to 1998 (1998) practical tests, satisfying the desired performance It was confirmed to exist, and it was formulated as a sonar for 01 type water craft in 2001 (Heisei 13)

OQQ-21

First of all, OQQ - 21 was installed on the type (Hyuga 16/18 DDH). It is equipped with huge cylindrical arrays (CA) · sonar equipped with ship's neck as a practical aircraft based on OQS-XX, and a long flank array (FA) · sonar equipped with a ship's bottom, Incorporating the AN / SQQ-89 (V) 15 of AN, SQUAREOUS SIGNAL PROCESSING DEVICE (SDPS), signal processing device, anti-submarine information processing device (ASWCS) There [13]. CA sonar and FA sonar share the function, which makes it possible to secure the required detection performance in various operational environments ranging from a long distance to a short distance, from a deep sea area to a shallow sea area. Moreover, by applying broadband element technology which was newly developed after the trial manufacture of OQS-XX (research prototype from 1997), it is possible to align the obstacle avoidance ability by high frequency as well as low frequency for long distance search against antithesis Succeeded. Also, towing sonar technology has been applied to the function as a listener

OQQ-22 was installed in an Akishuki type (19 DD), which omits Frank Array · sonar based on OQQ - 21 while integrating OQR - 3 TACTASS [22]. AN / UYQ-70 continues to be adopted as a standard computer board used for signal processing and the like

 

The OQQ - 23 is mounted on the mold (Izumo 22DDH), and it is composed only of the cylindrical array / sonar of OQQ - 22, with the flank array sonar and tow sonar omitted. In addition, since it does not carry anti-battle weapons of the same type in the same model, anti-submarine information processing equipment has also been omitted

 

OQQ-24

OQQ - 24 is scheduled to be installed in Asahi Shima, based on OQQ - 22, it is supposed to update towing sonar to OQR - 4 and strengthened by - / multi - static correspondence function There. This is to make the transmission and the reception by different ship, thereby achieving higher accuracy

 

Towed sonar (OQR)

It is equipped with a domestic development of passive passive sonar as domestic development of American tactical tower sonar (TACTASS), and OQR-1, Murasame type, Takanami type, Koncho type equipped later on Hatsuyuki type and Rabbit type There are OQR-2 equipped with the mold, OQR-3 equipped in the second generation, OQR-4 scheduled to be equipped in the Asahi type (2 generations).

 

Variable depth sonar (OQA)

There is OQA - 1 as the Japanese version of American AN / SQA - 10. It was equipped in the Showa 40s and was operated in cooperation with OQS-12/14, but operation was limited as with prototype aircraft. Thereafter, American-made AN / SQS-35 IVDS was introduced and operated as SQS-35 (J)

Japanese designations in general are not fun. Generally the sonar regime looks like:

 

HQS-x for dipping sonars

LQO-x for bottom sited fixed array sonars

OQS-x for surface ship hull sonars

OQR-x for surface ship towed array sonars

ZQQ-x for submarine hull sonars

ZQR-x for submarine towed array sonars

ZQS-x for mine hunting sonars

 

I expect to get to the Ships annex in the next month.

For a upcoming scenario:

 

I see entry #8850 S-79B1 HS.23 03 (Spanish Navy Seahawk 2003+) has not radar nor sonar (a slip obviously). As consequence it can be only employed for anti-surface attack.

 

Also, older entry #10702 Seahawk HS.23 88 (Spanish Navy Seahawk 1988-2002) should have not FLIR, as showed in this photo (last photo, ID 53097):

Some confussion in two Spanish CN-235 entries, both identical in the DB at this moment:

- Entry 8856 CN-235MPA D.4 (2010) is a correct maritime patrol type. At current times 8 maritime patrol aircrafts in service in Spain (Sometimes one deployed to Djibouti/Camp Lemmonier in Operation Orion, controlling sea lanes).

- Entry 8855 CN-235MPA T.19B should be a pure transport type named CN-235-100M T.19B, without SS radar, FLIR or ESM, and probably with loadouts 56725-Cargo and 52726-Assault. At current times 8 pure transports in service in Spain.

Pure Spanish transport CN-235-100M T.19B, without search radar, ESM or FLIR (You can read with difficulty T.19B on the vertical tailplane):

I see Loadout 54452 GP for 8810, 8811 CF-188A and 10909 FA-18D has not any bomb or similar.

 

(Also Iraqi Mirage F1EQ-5-200 with sea search Agave radar has not any loadout with AM.39 Exocet, as historically carried, and loadout 55820 SEAD (also employed by other Mirage F1) is equipped with 2xArmat, the limit should be 1xArmat or more specifically the older AS.37 Martel employed by Iraq.

The 18582 AM.39 Exocet is used in 55822 loadout of Mirage F1CT, and could be employed by Mirage F1EQ-5-200, but reducing from 2xExocet to 1xExocet. But I think these aircraft are not yet revised).

The Mirage F1 entries are currently under construction, so you can expect some attention here.

Working in a Gulf 1991 scenario, casually the 9575 Lynx HAS.3GM 90 entry is the only Lynx naval variant without radar, and uncapable to use Sea Skua with semi-active radar homing guidance!

 

(No, I see now also the 9557 Lynx Mk90B 01 (Denmark/Sea Spray Mk1), 9560 Lynx Mk88A 06 (Germany/Sea Spray Mk3), and 9572 Lynx HAS.2 85 (UK/Sea Spray Mk1) entries.

Ship entry 89 Adelaide (13) is classified as an US ship, of course she should be an Australian ship.

At current times all the S-3 Viking variants are uncapable to use aircraft carriers, as "Runway" is stated as "Small Aircraft", and not as "STOL Aircraft".

No, they work fine here.

 

Unless you are working with a carrier that still has its runway set to 'STOL' - and I had thought I had got all of them - it should work fine for you as well.

 

What matters is whether the 'Small aircraft' runway rating matches up with the ship's 'Small aircraft' runway rating.

Ok, I see.

I will look for the carriers with "STOL Aircraft" runway (Another time another big casuality, just the five Gulf War carriers I was employing!):
