STOCKHOLM, Feb 25 (Reuters) - The Aero Engine unit of Swedish truckmaker Volvo (VOLVb) said on Monday it had won a deal from Russia's Aeroflot to provide the company with engines used in the airline's DC 10-40 aircraft. Volvo Aero said in a statement the order was initially worth $60 million and that it was the largest overhaul contract signed by the unit since 1998. "There is also potential for a total order value of $120 million if Aeroflot decides to add more DC 10-40's to its fleet," the company said.
