Senior lecturer in the Military Academy of General Staff, department of electronic warfare(1972-1981 .)

"High assessment deserve the work of "CDB PM", which on the basis of advanced technologies have been created a unique radio-absorbing materials and absorbers of electromagnetic waves.
Thus, in 2006, the year for individual protection of missile complex
"Iskander-E" adopted a radar cloaking complex
PCMP-1L, providing concealment in the wavelength range of 0.2 - 15
centimeters with a reflectivity no worse than -17 dB."
in database:
Radar, E-M Band (2-100 GHz) -9,8 dBsm, 0,1 sq.m. -8,5 dBsm, 0,14 sq.m. -9,8 dBsm, 0,1 sq.m
About #38 - BPK Udaloy II [Pr.1155.1] and #417 - RKR Petr Velikiy [Pr.1144.2 Orlan, Ex-Yuri Androvo]and 533mm TT
both of them can use RPK-6 Vodopad from 533mm TT (in case of 1155.1 from 2x4 533mm TT, in case of 1144 from 2x5 533mm TT)

About USET-80 torpedo
there is no USET-80 torpedo on Soviet/Russian Navy surface ships , all of them use mix of 53-65K and SET-65 torpedoes
even for Talwars / 11356R this is 53-65KE/53-65K and SET-65SE/SET-65K
few citation:
"After extensive planning and testing torpedo UST-A "Tamga" under the name USET-80 entered service of the Soviet Navy. In 1980 after adopting in the practical shooting Navy
faced with a large number of misses in the Northern Fleet.
In the context of the Black Sea deep-water polygons Seeker
"Vodopad" achieve a desired response in the range of TTZ against
not evading submarines, but during testing in actual combat conditions,
including at shallow depths of the Northern Fleet, the results were unsatisfactory."
after that USET-80 send to rework and, citation:
"In 1988, on torpedo USET-80 was installed modified homing system "Keramica", the torpedo entered service under name USET-80K in 1989
on the torpedo mounted two-plane phase homing system "Keramica" with enhanced noise immunity from torpedo MPT-1, which is a copy of homing system US Mk-46 torpedo. In homing system "Keramica"(according to CNII "Gidropribor"), in contrast to the prototype, improved protection against means of sonar countermeasures."
but USET-80K came only for subs because, citation:
"Input data into a torpedo USET-80K is carried out not by mechanical spindle, but from electrical connection with the equipment ARVD-100 (missile unit data input)."
so ships that dont have ARVD-100 cant use USET-80K , and since there is no surface ships with ARVD-100 in 1989, Navy want mechanical input of data in USET-80K :
"In 1993 came USET-80KM - a variant of the torpedo USET-80K with mechanically ("spindle") input of data. Designed by CRI "Gidropribor" and OKB plant "Dagdizel."
but then Soviet Union fell , Russian Navy dont buy anything and all ships until now have only old 53-65K and SET-65S , then in 2007 came modernization of SET-65 with "Keramica" (SET-65K)
About #2306 - MPK Soobrazitelny [Pr.2038.1, Mod Steregushchy] and #2307 - MPK Steregushchy [Pr.2038.0]
On this ships missing surface search Radar "Monument-A"
citation:
"Electronic weapons of corvette includes CICS "Sigma-20380", the radar detection "Furke-2" radar for targeting missile weapons "Monument A" multi-functional television set MTK-201M2.2, universal fire control radar system "Puma" modified fire control system MR-123-02, two navigation radar MR-231 system state recognition "Password", two sets UVNTSU "Sandal-In." The structure of the electronic weapons includes a complex jamming TK-25-2 and complex interference PK-10 with four launch unit. Hydroacoustic equipment consists of a sonar system "Zarya-2" active-passive sonar to GPBA "Minotaur-M" and sonar detection PDSS "Anapa".

also #2306 - MPK Soobrazitelny [Pr.2038.1, Mod Steregushchy] shouldn't have this datalink:
SA-21/25 Command Datalink [20 Channels] SA-10/SA-N-6 Weapon Link 215 nm 20 LOS-limited, Secure, Send-only
since this ship dont have FCR , this limited anti-air missile that ship can use to 9M96
#2308 - MPK Gremyashchy [Pr.2038.5, Improved Steregushchy] should have ELINT/OECM TK-25 (2 ELINT stations and 4 OECM/DECM stations)
and FCR "Zaslon" :
fb.asp?m=3891483
with datalink for all Redut family of missiles:
fb.asp?m=3723893
about #2310 - SKR Admiral Sergey Gorshkov [Pr.2235.0] should have ELINT/OECM sustem TK-28 (aka 5P-28, bigger/better version of TK-25-7, 4 ELINT stations 6 OECM/DECM stations)
