Sarnitsa
Sarniza ( Russian Зарница , German: lightning ) is a Soviet Rundsicht- and target tracking radar system has been used which mainly torpedo and patrol boats. The NATO code name is Skin Head .
Structure and use
The system's antenna is located in a radome about 0.8 m in diameter and 1 m in height. The main task of the system is maritime surveillance and torpedo fire control equipment. In addition, it has severely limited airspace surveillance capabilities.
During the Second World War, PT speedboats were delivered to the Soviet Union under the Loan and Lease Act . The SO series radar used on some boats (e.g. the Higgins boats) probably served as the basis for the development of this device after the war.
The device was developed between 1946 and 1948 and tested in the Black Sea in the summer of 1948. During the tests, destroyers from 7.5 nm , torpedo boats from 3.4 nm and aircraft at an altitude of 100 to 300 m from 9 to 17 nm distance were located.
The system was used from 1950 and replaced from 1960 by radars of the types Reja and MR-102 Baklan .
The system was used in the following ship classes, among others:
- P-4 class (project 123)
- P-6 class (project 183)
- P-8 class (Project 183T)
- MO-IV class (Project 199) (partially)
Licensed buildings
In China, these devices were built in the 1960s. The Chinese name is unknown. The systems were used in the following Chinese and North Korean ship classes, among others:
- Hainan class (type 037)
- Shanghai II class (type 062)
- Chong Jin class
- Sin Hung class
