The White House appears set to allow American military contractors to travel and work in Ukraine to keep U.S.-provided weapons in operation.

The move would allow more U.S. nonmilitary personnel into the country as key systems, such as Lockheed Martin F-16s, are expected to arrive in the coming months. It also comes as the Biden administration has increasingly allowed Ukraine to fire U.S.-provided weapons beyond its borders into Russia.

A senior administration official told CNN that no decision has been made. If there is a change, it would allow the Pentagon to award contracts to U.S. companies to work inside Ukraine for the first time since the Russian invasion began in 2022, the network reported.

Pentagon spokesman Maj. Gen Patrick Ryder, when asked about the report on June 25, said he would not comment on internal discussions or proposals under consideration. Both President Joe Biden and Defense Secretary Lloyd Austin have said U.S. troops will not go to fight in Ukraine and “that won’t change,” he says.

While many U.S.-provided weapons have been sent to Ukraine and have been in operation since the invasion, the bulk of those that need repairs have to be shipped outside of its borders. U.S. companies and service members have provided remote support to Ukrainian forces.

Several key U.S. defense company leaders have traveled to Ukraine for discussions with top officials about their systems, but without publicly providing contractors to work in the country.

Ukraine will get its first F-16s this summer, Chairman of Joint Chiefs Gen. Charles Q. Brown Jr. said in a June 13 press conference.
