Israel (IAF) begins deployment of Arrow-3 anti missile defense

[DefeseNews] "Today
Jan 18 2017
we're entering a new era; the Arrow-3 era," said Moshe Patel, head of the Israel Missile Defense Organization (IMDO). "We're very proud to deliver to the Israel Air Force the first initial capability of Arrow-3 … [a program] we've worked on for the last ten years, together with MDA and with a lot of help from the US Congress and the US administration."

Designed to fly nearly twice as high
up to 60 miles
at half the weight of Arrow-2 ‐ which covers the lower-tier segment of AWS ‐ Arrow-3 is Israel's first line of defense against advanced, maneuvering Iranian Shihab-class ballistic missiles.

What mass was sacrificed to get the range?
Did they replace HE with NUC?

#2 certainly the sensors are better and smaller than arrow 2

also, the thrust delivery is probably more efficient which would mean less fuel needed to carry but that's guesswork

#3 What mass was sacrificed to get the range?

Maybe they reduced the size of the warning label.

#4 Well, one really don't need as much explosion energy as one thought before to destroy an incoming missile. One just need to get somewhat near it and a small high flak explosion is all that's needed to knock the incoming missile out.

Below is a picture of an Arrow2:

So image the Arrow3 at half the weight and much greater range. Keep in mind that "half the weight" is not the dame thing as "half the size". This way the Israels can use the existing Arrow2 infrastructure, saving quit a bit of cash.
