Lockheed Martin [LMT] yesterday said it has signed a contract to provide South Korea four C-130J Super Hercules aircraft.

“Because it is a legacy C-130 operator, the Republic of Korea Air Force is able to take advantage of common spares, support equipment and a sound knowledge of the C-130 to reduce costs and reach full operational capability as soon as possible,” Jim Grant, Lockheed Martin vice president for Air Mobility and Special Operations Forces Programs, said in a statement. “As an experienced C-130 operator, Korea recognizes the unmatched capability that this new aircraft brings to so many missions.”

Korea’s new Super Hercules will be the longer fuselage or “stretched” combat delivery variant. Deliveries will be in 2014 and the contract also contains a two-year support program including aircrew and maintenance training. Korea joins 14 other nations that have selected the proven C-130J.

The company said the C-130J generates greater operational efficiency than older C-130s–such as Korea’s current H models–by flying further, faster, with more payload and higher reliability.

Additionally, the C-130J only requires three crewmembers for most missions, so fewer flight crewmembers are exposed to potential threats.

C-130Js are used daily for troop and equipment re-supply via ground delivery and airdrop, for air-to-air refueling, ground refueling and humanitarian relief.

Lockheed Martin and Korea have been industrial partners for more than 20 years, beginning with the F-16 Peace Bridge program in the late 1980s.

Korea Aerospace Industries (KAI) began manufacturing center fuselages for F-16s, which evolved into licensed production of F-16s for the ROKAF.

The ROKAF T-50 Golden Eagle was developed through collaboration between KAI and Lockheed Martin.

Release of the contract value was not approved for release by the customer, the company said yesterday.
