Description:

The Lockheed P-3 Orion is a four-engine turboprop long-range anti-submarine and maritime surveillance aircraft developed for the United States Navy and introduced in the 1960s.

Republic of Korea Navy - eight P-3Cs, eight P-3CKs; based in Pohang Airport and Jeju international airport. Korean Air/L-3 Communications are upgrading the P-3C aircraft with new electronics, including new magnetic anomaly detectors, electro-optical sensors, surveillance equipment and a self-protection suite. The Navy's impetus stems from a 2010 experience in which ROK forces detected only 28% of North Korean submarines involved in exercises.

P-3CK:
Designation of the eight former USN P-3B TACNAVMOD aircraft that the Republic of Korea Navy procured from the USN and which are in the process of being rebuilt with P-3C configuration wings and fitted with updated Mission System Equipment by Korea Aerospace Industries and L-3 Communications.
