The United States is mulling over selling three Cobra helicopters and several Predator surveillance aircraft to Turkey, to be delivered by the end of the year to assist in the campaign against the PKK.

The Defense Security Cooperation Agency (DSCA) has formally notified the US Congress of a possible sale of AH-1W Super Cobra Attack helicopters to Turkey, CNN reported on Friday.

Ankara has been seeking the helicopters to replace those lost in its long struggle against separatist rebels of the Kurdistan Workers' Party, which is also known by its Kurdish acronym, the PKK.

The deal, valued at up to $111 million, would "improve Turkey's capability for self defense, modernization, regional security and inter-operability with US and other NATO members," the DSCA said in a statement.

"AH-1W helicopters are already in the Turkish Land Forces Command inventory and will further enhance Turkey's ground defense capabilities."
