Since 2013 Peru is in talks with European suppliers as part of a long-term plan of replacing FAP's aging air force aircraft with second-hand Su-35s, Rafales or Eurofighters. Hitherto, FAP was exploring the possibility of buying as many as sixty Eurofighter Typhoon EF-2000 from Spain and sixty Sukhoi Su-35 from Russia. Cost was a major issue for Peruvian President Ollanta Humala, who was looking at competitively priced fighter jets that would fit the national budget. In 2014, Peru began to update the operations and mechanical equipment of its Cessna A-37 aircraft, replacing analog controls with new digital hardware.
