Pakistan has agreed to extend the deadline for the delivery of 30 T129 ATAK attack helicopters by one year, to allow Turkish Aerospace Industries (TAI) to work around a US veto on the re-export of their turboshaft engines. In 2018, TAI signed a $1.5 billion contract to provide an initial batch of 30 T129 ATAK attack helicopters to Pakistan, assuming the US government would allow the re-export of their US-made LHTEC T800-4A turboshaft engines. This was declined by US. TAI is now looking to Tusas Engine Industries, its sister company, to develop a new, indigenous engine to replace the T800. The first production engines are expected to be available in 2025, which will considerably exceed the one-year extension accepted by Pakistan.
