A second U.S.-made advanced surveillance aircraft has been delivered to Korea's Air Force, the state procurement agency said Tuesday.

The Defense Acquisition Program Administration (DAPA) said the Air Force will soon deploy its second E-737 by Boeing. Based on Boeing's 737-700, the airborne early warning and control (AEW&C) aircraft earned the moniker "Peace Eye" after a naming contest in 2008.

In 2006, Korea reached a $1.6 billion deal with Boeing to purchase four E-737s. The first Peace Eye arrived in South Korea in August and was delivered to the Air Force in September.

The DAPA said that under Boeing's supervision, Korea Aerospace Industries (KAI), a local aerospace company, built the radar and other electronic parts on the second E-737.

The E-737, equipped with a sophisticated radar system called Multi-role Electronically Scanned Array (MESA), can detect and monitor up to 1,000 airborne or surface targets simultaneously, it said. (Yonhap)
