How can a sub based on 40s technology capable of firing anti ship missile? Did any of the German XXI sub capable of firing anti ship missile? Please do not misled by bogus sources. Those western explanation of Type 035 sub , know nothing and just typical cut and paste from 40 years old data.
Type 035G: Program begun in 1985, and the first unit with pennant number 356 was lunched in 1989, service in December 1990, and state certification received in 1993. This is the first Type 035 series to have anti-submarine (ASW) capability. The primary weaponry for Type 035G is Yu-3 torpedo, and French sonar DUUX-5 and its Chinese built version were used on later units, 12 of which were completed between 1990 to 1999. The last unit with pennant number 308 was lengthened by 2 meters to add a section for AIP tests.
If BD buys the 035G version, they are basically still quite new and they are no 40s technology. Special tiles are added on surface to reduce sonar detection, same as Kilo. The anti ship capabilites maybe added on to constant upgrade the sub.
