The US State Department has approved a potential $2.68 billion Foreign Military Sale (FMS) to Ukraine covering an air-defence upgrade package that includes missiles described as S-300 Clones.
The proposed sale comes as Ukraine continues to face sustained Russian missile and drone attacks while dealing with shortages of air-defence interceptors, including Patriot missiles.
Under the potential agreement, Ukraine would receive S-300 Clone missiles, GAM-67 missiles, Range-Extended Air Defence Laser-Guided Rocket missile systems, Improvised Transporter Erector Launcher 1.5 systems, mobile launcher modification kits, RPS 202 counter-unmanned aircraft system (C-UAS) radars, and erectable mast trailers.
The package would also include major modifications and maintenance support, spare parts, consumables, accessories, repair-and-return services, software, transportation, and engineering, technical and logistics assistance from the US government and contractors.
According to the State Department, the proposed sale would strengthen Ukraine’s ability to respond to existing and emerging threats by providing a more capable and robust air-defence architecture.
However, no contract has been awarded at this stage. The proposed FMS would involve a competitive contractor-selection process before specific suppliers are chosen.
S-300 Clone Missiles
The State Department has not released technical specifications for the S-300 Clone missiles, GAM-67 missiles, or Range-Extended Air Defence Laser-Guided Rocket systems included in the package.
Colonel Robert Hamilton (Ret.), president of the Delphi Global Research Center, told CBS News last month that the United States and Ukraine are reportedly working to upgrade older S-300 missiles or develop a newer S-300 variant with enhanced capabilities. According to Hamilton, the missiles could become available by the end of this year, with annual production potentially reaching 100 to 200 units.
Meanwhile, Defense Express reported that the S-300 Clone is a newly designed missile featuring improved performance and a more advanced guidance system, rather than a direct reproduction of the Soviet-era 5V55 interceptor.
The GAM-67 designation also has a historical connection to an unrealized US anti-radiation missile program from the 1950s. The designation is now reportedly associated with a newly developed weapon intended for medium-range air-defence applications. Such systems could potentially be integrated with Soviet-era air-defence platforms already operated by Ukraine as well as newer systems under development.
The proposed package reflects efforts to expand Ukraine’s air-defence capabilities through a combination of new interceptors, launcher upgrades, counter-drone sensors, maintenance support and technical assistance. If implemented, the programme could also contribute to sustaining and modernizing Ukraine’s existing air-defence infrastructure while improving its ability to address a broader range of aerial threats.
