Elisra Electronic Systems has won a $29 million contract to supply South Korea with airborne electronic warfare suites for its CN-235 transports.

The deal for Elisra comes after a 2009 contract worth around $25 million for integrated electronic warfare suites for South Korea's fleet of Lockheed Martin C-130H tactical transports.

Also in 2009, Elisra signed a $7 million contract for early warning equipment for four prototype Korea Aerospace Industries F/A-50 strike aircraft. The deal included advanced radar warning receiver as well as chaff and flare dispensers.

The South Korean air force operates around 20 of the high-wing, medium-range, twin-engine CN-235. The transport plane, which first flew in 1983, is a joint development by Casa, Airbus's Spanish subsidiary, and Dirgantara Indonesia, formerly called Industri Pesawat Terbang Nusantara -- IPTN.

The CN-235 primary military roles include maritime patrol and surveillance. Turkey is believed to be the largest user, with 61 aircraft.

In late 2008, South Korea's coast guard signed a $92 million deal for four CN-235 aircraft to compliment its fleet of 15 helicopters and one patrol plane. The four planes will be handed over by 2012.

Normal CN-235 configuration uses two General Electric CT7-9C turboprop engines with four-bladed Hamilton Standard HS 14 RF-21 propellers. Maximum speed is around 265 mph with a service ceiling of 26,000 feet.

Elisra, which has headquarters in Haifa, Israel, is 70 percent owned by Elbit Systems and 30 percent owned by Israel Aerospace Industries.

Elisra designs, manufactures and integrates electronic protection systems for air, sea and land deployment. It was set up in 1967 and owns two stand-alone companies, Tadiran Electronic Systems and Tadiran Spectralink. Elisra's clients are found in more than 40 countries, a company statement said.

Tadiran Electronic Systems developed and manufacturers the Battle Management C3I Center for the Arrow anti-ballistic weapons system, a joint missile development by Israel Aerospace Industries and Boeing.

The Israeli Arrow is considered more advanced than Raytheon's Patriot missile. The Arrow has a greater range of around 54 miles and a 30-mile altitude limit, allowing for higher altitude interceptions.

Tadiran Spectralink focuses on advanced wireless communication products such as search and rescue systems for combat and peacetime applications.

Last month, Elbit systems said it had received an $18 million order from an Asian air force but declined to name the country.

Elbit said the agreement will be completed within two years. It is also a follow-on order for two more complete systems -- static and mobile -- to be used for real-time, autonomous air-to-air and air-to-ground combat training and debriefing.
