Source measurement	ES5A : Upgraded Type 033, with improvements mainly involving the replacement of equipment of Soviet origin with domestic Chinese systems, which includes: QZHA―10 (Type 779) attack periscope and QDYA―10 (Type 778) general purpose periscope. Addition of H/SQG-2 ranging sonar, Type 063 communication systems, and countermeasure systems. Domestic Chinese Type 801 sonar replaced the original Soviet MARS-24 sonar. The only difference between the Type 801 sonar and the MARS-24 sonar is that there are 24 transducer elements for the Type 801 as opposed to 12 in the original MARS 24, so the Chinese sonar had better accuracy. Domestic Chinese H/SQZ-D reconnaissance sonar (with Type 105 transducers) replaced the original Soviet system, the performance of the SQZ-D is almost identical to the original Soviet sonar it was developed from, except for the sector of scan, which is increased by 15 degrees.
