The Jericho II as an available Israeli counterattack option to Iraqi missile bombardment in the 1991 Gulf War is disputed. Jane's at the time believed that Jericho II entered service in 1989. Researcher Seth Carus claims that, according to an Israeli source, the decision to operationally deploy the Jericho-2 was only made after 1994, several years after the Scud attacks had ended and a cease fire and disarmament regime were in place. Raytheon Technologies, quoting Soviet intelligence archives, showed them believing the Jericho-2 to have been fully developed weapon in 1989, but did not indicate when it was available for deployment. Investigators for the Carnegie Endowment for International Peace accessed commercial satellite images of the Sdot Micha Airbase near Zachariah, a suspected Jericho missile base, comparison shows expansion between 1989 and 1993 of the type that would accommodate suspected Jericho II launchers and missiles. Such an expansion would be more consistent with a post-1991 deployment chronology.
