Israeli drones believed to be armed according to foreign media.
their were several reports on this subject for years now.
IDF keeps ambiguity on most of his newest weapons (For example the Pereh tank with Spike missile project from the 80's which got unclassified only in the last year - 30 years later)
Israel got the technology, the means - drone platform which can carry such weight (hermes 450, hermes 900, heron & heron tp) , mini spikes missiles and hellfire missiles which can be launched from a drone.
It is also believed that Israel helped the USA develop it's own drone program including arming them.
Infact, it was an Israeli who helped the USA develop it's Predator - "The company's owner, Abraham Karem, was the former chief designer for the Israeli Air Force, and had emigrated to the U.S. in the late 1970s. Karem's company had since gone bankrupt and been bought up by a U.S. defense contractor, from whom the CIA secretly bought five drones (now called the "GNAT"). Karem agreed to produce a quiet engine for the vehicle, which had until then sounded like "a lawnmower in the sky". The new development became known as the "Predator"."
I don't know if Israel sold those technologies to India combined with the drone deals, but I believe so.
