There are two things here Sire. No one leaked the news of RAAD and in the case of SD-10B the news was leaked.Okay
Second thing is, RAAD is being regularly tested, any news of SD-10B being tested or just as the news leaked of SD-10b , did any news of SD-10B leaked? So it's still a smoke screen right now.
Let me remind you the story of MAR-1. That was the strategic missile, so much controversy attached to it due to indian Pressure, even PAF didn't acknowledge it's purchase but they disclosed when the MAR-1 got integrated with JF-17. Now for the SD-10B, No matter how strategic it is when it's existence becomes known, then it should be acknowledged officially to.
