The fins are visible in the picture above. Indranil: in the pics I've seen so far, I can't make out the fins. If you look at Agni-2 pictures, the fins are prominent Agni-2 has a blunt nose RV, it creates a wider shockwave. Hence, A2 needs bigger fins for trimming. In A-P they are for a different pu...

A modern AESA radar (designed with the current tech) should weight less than a much older PESA design. It will also be more efficient, and within an unchanged power and thermal margin, https://4.bp.blogspot.com/-C_Iz_KixYuA/WyUPJ_ivJRI/AAAAAAAAT14/sln5oA3H9UMB72vbTPJflMRo_Fmfw6AtQCLcBGAs/s640/MMR%2...

South Korea seems to have made a fairly weird trade with their radar. They don't have a slick RCS optimized aircraft yet the radar seems to be sized quite conservatively. The first prototype that was C-130 tested had just a tad over 1,000 T/R modules and ultimately they want to work up to 1,200. Gi...

The name 'Surya' dates back to 1994, and it was used for Agni-4 (Surya-1) and modified PSLV (Surya-2). Everything related to Surya is a whole lot of Raayta.

The shape of the payload fairing (K4) doesn't have anything to do with reentry. It's just a protective cowling which is ejected when the missile leaves the lower atmosphere

Weighing only 120 tons, SSLV is lighter than Soviet and PRC ICBMs.As of its length, it's only slightly (~2m) taller than R-36 and DF-5. Stationing SSLVs at a fixed strategic location makes more sense because it would make mating with a payload easier. In any case, it would be prudent to keep some SS...
