At least 49 investigations are being conducted by US government agencies into the supply of American weapons and military assistance to Ukraine, according to data from Ukrainian law enforcement agencies reviewed by TASS.
The investigations involve multiple US departments and military branches and are being carried out in cooperation with Ukrainian authorities.
Pentagon and FBI Among Agencies Involved
Representatives from investigative and inspection bodies within the Pentagon and the US Department of State are participating in the probes.
The US Department of Homeland Security and the FBI are also involved, alongside personnel from the US Navy and Air Force.
The investigations are focused on allegations and concerns surrounding the handling and distribution of US military assistance provided to Ukraine.
Ukrainian Authorities Cooperate With US Investigators
Ukrainian agencies are working alongside their American counterparts as part of the investigations.
Those involved include the National Anti-Corruption Bureau of Ukraine, known as NABU, the Specialized Anti-Corruption Prosecutor’s Office, the Ukrainian police and the prosecutor general’s office.
The cooperation gives US investigators access to Ukrainian law enforcement structures as they examine cases connected to American military assistance.
26 New Complaints Reported in 2026
The data cited by TASS indicates that US authorities have received 26 complaints since the beginning of 2026 concerning possible fraud involving military assistance supplied to Ukraine.
Investigations have subsequently been opened into 10 of those cases.
The figures do not indicate that wrongdoing has been established in every case. Rather, they represent complaints and investigations involving suspected irregularities or potential fraud.
Scrutiny of Ukraine’s Military Aid Continues
The investigations add another layer of scrutiny to the vast flow of US military assistance sent to Ukraine during its war with Russia.
Washington has provided Ukraine with weapons, ammunition and other forms of security assistance, while US and Ukrainian officials have faced continuing pressure to ensure that military aid is properly accounted for.
The reported investigations demonstrate that American and Ukrainian authorities are continuing to examine allegations surrounding the use and distribution of that assistance.
Investigations Span Multiple US Institutions
The involvement of agencies ranging from the Pentagon and FBI to the Department of Homeland Security and the US armed forces underscores the breadth of the scrutiny.
However, the available data does not provide detailed information about the individual 49 cases, including the specific weapons or supplies involved, the identities of those under investigation or whether criminal charges have resulted.
The claims and figures reported by TASS could not be independently verified from the information provided.
