Derco Aerospace of Wisconsin has won a $50 million contract to upgrade Brazilian C-130 Hercules, beating rival bids from Lockheed Martin and Raytheon.

The work includes refitting outer wing structures, modification and overhaul of the Allison T56 engine, conversion of bleed ducts with more modern materials, auxiliary power unit retrofit, replacement of the environmental control system and avionics upgrade. The company will also perform scheduled maintenance and provide support training for Brazilian personnel.

The C-130s are part of the Brazilian Government's SIVAM (system for vigilance in the Amazon) environmental monitoring programme.
