Rome, May 2 - Alenia Aermacchi, part of Italy's Finmeccanica group, and Lockheed Martin on Thursday announced in a statement they have sealed a contract worth 141 million dollars for the production of the wings and a number of other components of the controversial F-35 fighter jet JSF (Joint Strike Fighter). Alenia Aermacchi will produce the jet's wings and wing boxes in its factories in Foggia and Nola, near Naples, and in its new plant in Cameri, in northern Italy. At an estimated $200 million per unit, the F-35 is the costliest fighter jet in the world. With radar-evading technology, it has been championed for its advanced design but also heavily criticized for allegedly not meeting the criteria of modern warfare. Amid the economic crisis, last year the Italian government announced plans to cut its order to 90 from the 131 originally agreed in 2002.
