South Korean Air Force has considered acquiring two more Peace Eye airborne early warning and control aircraft to better regulate and protect the country's Korean Air Defense Identification Zone from all possible intruders
The E-737s delivers South Korea the ability. The acquisition move will increase the number of E-737s to six, strengthening the country's operational capabilities. E-737 gives the Air Force better situational awareness and also control over its aerial assets. Besides it provides air force more capacity to gather signal intelligence. The presence of the planes can act as deterrence against the North which does not have similar platforms.
In the past there had only been speculation about increasing the size of the AEW&C fleet, but it has now been 'confirmed' to be part of the long-term acquisition plan.
