The first replacement center wing box for the L-100 civil variant of the Hercules was delivered to Lynden Air Cargo on 25 January 2011. The new wing box is the first of three on order for Lynden, a freight transport firm in Anchorage, Alaska, that operates a fleet of six L-100s. The new structure will give the Lynden L-100s an additional fifteen years of service life. Installation will be performed by Singapore Technologies Aerospace Engineering using Lockheed Martin-designed tooling. Center wing boxes for installation in new C-130J Super Hercules and for retrofit into earlier Hercules models are manufactured at Lockheed Martin in Marietta, Georgia.
