What are "S-300 Clone" and GAM-67 in the new $2.68 billion US package for Ukraine?
The US has announced a new $2.68 billion military aid package for Ukraine that references two previously unknown items, "S-300 Clone" and GAM-67, and experts say they believe they have figured out what they are.

The United States has announced a new military assistance package for Ukraine worth $2.68 billion. Documentation related to the package includes two designations that had not previously appeared publicly — "S-300 Clone" and GAM-67. With no official explanation offered, military analysts and experts have begun offering their own assessments of what these items actually are.
The "S-300 Clone" theory
According to analysts, the label "S-300 Clone" is believed to refer to newly built American missiles designed to be fired from Ukraine's existing Soviet-era S-300 air defense launchers. This would matter because Ukraine's stockpile of original S-300 missiles has been depleting, even though the launch platforms themselves remain operational. If the United States can supply new missiles compatible with these Soviet-designed launchers, Ukraine could keep using its current air defense infrastructure rather than needing entirely new launch systems.
GAM-67 still unclear
The package also references a second item, GAM-67, though little public detail is currently available about its specific role, and experts are still working to determine what it is.
The appearance of these coded designations in US aid documentation suggests that part of the assistance to Ukraine is being structured around newly developed components adapted to fit Ukraine's existing, largely Soviet-origin weapons systems, rather than as deliveries of entirely new Western equipment.
