Government has signed a pact with Ukraine to upgrade Indian Air Force's fleet of An-32 transport aircraft, Defence Minister A K Antony said on Monday.

"A contract for upgradation of An-32 aircraft has been signed with State Foreign Trade Enterprise 'Spetstechnoexport' (STE), Ukraine on June 15, 2009 for total technical life extension (TTLE), overhaul and re-equipment of the aircraft in IAF fleet," Antony said while replying to a Lok Sabha query.

The Minister said that the upgrades will enhance IAF's An-32 fleet's life by another 15 years.

"The calendar life of An-32 aircraft will be enhanced from 25 years to 40 years," he said.

He added that the aircraft will be upgraded between 2009-17 and $397.7 million would be spent on the process.

IAF has a fleet of around 100 An-32s, which were procured from the erstwhile Soviet Union in the 80s.

Meanwhile, replying to another question, Antony said that the Hindustan Aeronautics Limited has approved a new campus for its management academy in Bangalore.
