@TheInsider did you hear anything about Hisar O date and Hisar U ?
Hisar-O+ IIR version definitely will be available this year. Hisar-RF will probably slip to Q1 2022. Hisar-U is the 70-90km missile that was mentioned before. It seems like it is coming better than expected (estimated range in design phase vs tested range today). I expect Hisar-U to be available by the end of 2022 and probably by the end of 2023 Siper missile system will be available.
Hisar-A--->Hisar-A+ (same body with Hisar-A some changes to rocket engine and fuel composition)
Hisar-O--->Hisar-O+(same body with Hisar-O some changes to rocket engine and fuel composition)
Hisar-RF---> Similar body with Hisar-O some optimization work done on the body and inner components)
Hisar-U---> Hisar-RF with an enlarged completely new body estimated to have 70-90km range earlier now probably "+" improvements applied to it and it is coming better than expected.
Siper---->Earlier it is expected to be a 120km range missile with a dual seeker(RF+IIR) . Now I expect it to reach 150km.
BTW in Hisar-A+s latest test, the missile intercepted the target above 30k feet (~10km). So the range-altitude numbers i was told seem on spot.
