of 6 Mi-8MTV-1 underwent an overhaul again in 2013 and 2014, while the remaining 8 units are to follow in 2014 and 2015. The Croatian Ministry of Defence is considering the option of selling all Mi-8 helicopters upon overhaul and replacing them with up to 15 UH-60L after 2017. In 2006, a deal to deliver 10 new Mi-171Sh transport-attack helicopters was signed with Russia, itself a partial payment for an old Russian debt. The order itself was worth $66 million. The new type differs from the ones already in service in having a cargo ramp instead of clamshell doors, larger side doors, flare dispensers, additional armour around the cockpit and cargo compartment, night vision device equipment, door gunner posts, rocket launchers etc. The entire squadron of 10 helicopters entered service by July 2008. Two additional VIP helicopters were planned for 2009 but their acquisition was cancelled. After more than 10 years in the Croatian service and great success in Operation Storm, the government finally decided to retire a squadron of seven Mi-24V helicopters in 2005 due to a costly modernisation. Six are offered for sale at a price of $83,000 per aircraft, while one was sent to a museum. The role of an armed support helicopter was taken over by new Mi-171s but the entire attack helicopter squadron is to be revived in 2015 with the acquisition of up to 16 OH-58D. While visiting Israel in November 2006, Croatian delegation agreed to buy two mid-size, state-of-the-art Hermes 450 and four small Skylark UAVs. Additional cameras, computer systems, spare parts and a ground station were also obtained. Two additional Skylark UAVs entered service in 2009. As of December 2012, additional Skylarks has been reported in service though no public records or images of Croatian Hermes 450 are available. This suggests that the order was cancelled due to funding issues. After a horrible fire season during the summer of 2007 (12 firefighters lost their lives on a small island of Kornati), Croatia agreed to buy two new Canadair CL-415 and five Air Tractor AT-802 water bombers. These joined a fleet of four relatively new amphibians already in service. The entire deal was projected at $70 million. By making such an acquisition, Croatia became the leading power in aerial firefighting on the Mediterranean in respect to its population and surface. The Croatian Air Force holds a world record of 160 water drops by
