South Korea could obtain 14 used Boeing CH-47D Chinook helicopters from US army forces stationed in the country.
The proposed $151 million deal would be conducted under the US Foreign Military Sales (FMS) mechanism, according to a statement by the Defense Security Cooperation Agency (DSCA).
If the sale is approved, the aircraft would be transferred to South Korean forces incrementally as US army units take delivery of new-build CH-47Fs.
The proposed deal would save the US army about $13.4 million that would otherwise need to be spent on demilitarising or transporting the aircraft.
