Rank 63 in the Aviation Heroes collection, this print treats the KAI KF-21 Boramae as the Republic of Korea Air Force's domestically engineered 4.5-generation answer — not as interchangeable grey-jet filler on white. Named Boramae after the Korean word for a young fighting hawk, the programme rolled out its first prototype in April 2021 and cleared first flight on 19 July 2022; prototype 006 — the final test airframe and one of only two twin-seat Boramaes built — later flew the 2023 Armed Forces Day formation over Seoul, the same tail number stamped on this plate. The 1st Fighter Wing at Wonju Air Base anchors the poster's unit framing as ROKAF development and evaluation ops wrapped around KAI's Sacheon production line, while the loadout diagram calls out what collectors actually hunt for: Meteor beyond-visual-range rails, IRIS-T dogfight missiles, and GBU-38 JDAMs bracketing a centreline tank on a canard-less delta that South Korea designed to sit between its F-35A stealth fleet and retiring F-4E and F-5E squadrons.
