Re: Indian Missiles News & Discussions - 17 Dec 2018

the B52 can only take the object upto 10km high and speed of 800kmph. so even the US hypersonics will need a jettisonable solid fuel booster to reach the height and speed to try the scramjet engine. we dont have B52 so thats not an option. they can get away with a smaller booster. in the good old d...

Karan, Why care? If there is an ASAT test, there would be debris. Actually, head on collision creates the lowest chances of debris to reach higher apogee orbits.
