How many Israel A-4N "Ayit" were fitted with ARBS laser spotter?

I was just curious if anyone has any information on how many Israeli A-4N’s received the ARBS laser spotter in the nose of the aircraft giving it the capability to guide Laser GBU’s. I think this could good be a great addition to the Israel air tree, If applied to the current A-4N in tree or as a separate aircraft

It doesn’t provide any laser designation capability whatsoever. It’s only capable Laser Spot Tracking so speeds the acquisition / slewing of the bomb’s own seeker.


Thank you for the Clarification
