Default Russian torprdoe info

Anyone out there with a comprehensive Russian Sub weapon sourse/documents? I'm having trouble with torpedoe attributes.For example 65-76 ,some sites say wire guided, some say no...it has TERMINAL wake homing but it still has to get there, making me think its still wire guided in initial stage of firing.Also the uset-80...does it have a wire guided version...found this which makes me question it. "USET-80KM Variant of USET-80K with mechanical fire control inputs, instead of digital as on USET-80 and -80K". What is meant by "mechanical fire control inputs"??

Description
Introduction
The USET-80 is a late Cold War era heavyweight torpedo of Soviet origin. It was developed as a universal torpedo for use by submarines. A universal torpedo can be used against both submarines and surface targets.

Design
The USET-80 is a heavyweight torpedo with 533mm diameter. Soviet torpedoes of this diameter are longer than their Western counterparts. USET-80 uses electric propulsion which allows it to dive very deep. Possibly up to 1 km depth, or more. Maximum speed is reported between 45 and 48 knots.

Guidance
The USET-80 uses passive acoustic homing against submarines and active acoustic homing in the terminal phase. When employed against surface vessels the USET-80 uses acoustic wake homing. There is no wire guidance for mid course updates. The original USET-80 with its Vodopad acoustic sensor had a very poor track record in shallow waters and under the ice, while it worked well in deep open waters. For this reason the active homing SAET-60M was, and possible still is, used alongside the USET-80. The improved Keramika sensor in the USET-80K showed better results in shallow waters. Both sensor types were deemed of mediocre performance by late Cold War standards.

Firepower
The warhead of the USET-80 is in the 200 to 300 kg range, which is effective against both submarines and larger surface vessels. Detonation is either by impact or magnetic proximity fuse.

Launch platforms
The USET-80 can be launched by a wide range of late Cold War era Soviet submarines and modern Russian submarines. For several decades it was one of the main torpedoes found on Soviet/Russian submarines. Apparently it is not used on surface vessels or ASW aircraft.

Users
The USET-80 was adopted in quantity by the Soviet navy and continued in service with the Russian navy. The USET-80 and USET-80K remain in service today, even on modern submarines like Project 955 Borei class.

Variants
USET-80 Initial production version, first introduced in 1980. Fitted with "Vodopad" acoustic sensor.
USET-80K Variant introduced in 1989. Fitted with "Keramika" acoustic sensor.
USET-80KM Variant of USET-80K with mechanical fire control inputs, instead of digital as on USET-80 and -80K.
TE2 Export variant of USET-80(K?) marketed in the early 2000's. Comes in three different models.

Description
Introduction
The Type 65-76 torpedo is a very large Cold War era torpedo of Soviet origin. Due to their size the use of these weapon was limited to only a very few types of submarines. The Type 65 is one of the most capable anti-ship torpedoes in existence as it has a very high speed, a very long range and a very powerful payload. The Type 65 is also a very dangerous weapon system that needs to be handled with care due to its hydrogen peroxide fuel. A Type 65 torpedo has been blamed for the explosion that sunk the Russian Kursk nuclear powered missile submarine.

Design
The Type 65 may have started out as an up-scaled Type 53-65K torpedo. The Type 65 has a diameter of 650mm and a length of over 11 meters. Development started at the same time as the Type 65-73, which entered service earlier since as a non-homing torpedo it required less development. The wake homing seeker is located in the nose with the warhead directly behind it. The fuel and turbine engine make up most of the center. The use of high test peroxide fuel provides a lot of power, with the drawback of being highly volatile. Unusually the guidance section is in the rear. The two contra-rotating propellers are encased by control planes.

Guidance
The Type 65-76 is intended for use against surface vessels and uses acoustic wake homing. This method of homing is very difficult to jam. Inertial navigation by means of gyroscopes is used to guide the weapon to a position where the wake can be picked up. The Type 65-73A with improved signal processing capabilities was introduced in the early 1990's.

Firepower
The Type 65-76 torpedo has a warhead of at least 450 kg, making it powerful enough to sink an aircraft carrier with only one torpedo. The warhead has both impact and proximity fuses. Maximum range is about 50 km at its 50 kt maximum speed, or about 100 km at a slower pace of 30 kt.

Launch platforms
Type 65-76 torpedoes are solely used on Soviet/Russian submarines. Due to its size the 650mm torpedoes are only used on large submarines. Several Soviet SSN and SSBN designs since 1972 feature 650mm torpedo tubes, alongside 533mm torpedo tubes. Recent Russian submarines no longer feature 650mm tubes, slowly marking the end for this type of torpedo. Use on surface ships and coastal defense launchers has been proposed but haven't materialized.

Users
The Type 65-76 torpedo is only used by USSR, with all transferred to Russia. The accident with the Kursk led all Type 65's to be stored. However, they remained in limited use by 2019 and possibly today. Variants of 650mm torpedoes have been offered for export. There are reports that China adopted Type 65 technology

Thankyou...helps alot...2 questions though...you mentioned last night there was a guided 65...was it a proto type..did it see service?(wiki says Guidance
system
active/passive sonar and wire guidance


Secondly...in our weapons text files...are the distance/weights for sensors/warheads in metric or imperial? I see the 65-76 is 375 warhead but your post says 300kg.Is there a gameplay adjustment going on here...or a mistake? (I see there are also discrepancies in launch depth)

I "think" it's this:
weapon Kg
sensor yards
depth feet

Right now, 65-76 in DotMod initially runs at 50 knots and then slows down to 45 knots when active.

With the new changes in accordance with this data, the initial speed should be 30 knots with a 100km range and then 50 knots once the sensor goes active.

MaxLaunchDepth is 1575 right now, which is very excessive, so we can change this to the equivalent of 150m in feet.
