Wallimilist Aviation Heroes V7 — 2 museum-grade prints on the theme. The AH-64E Apache Guardian — Boeing's Block III evolution of the Apache line — introduced improved engines, composite rotor blades, and the AN/APG-78 Longbow fire-control radar that lets crews engage targets from masked positions. South Korea's initial 36-airframe order, contracted in 2013 and delivered from 2016, equipped the Republic's first dedicated Apache Guardian battalions with AGM-114 Hellfire, Hydra 70 rockets, and the chin-mounted M230 30 mm chain gun. The F-15EX Eagle II is Boeing's latest USAF Eagle variant, derived from the F-15QA export design and built to replace aging F-15C/D air superiority fighters. The 142nd Wing's selection as the first operational unit — ahead of many active-duty wings — reflects Portland's long Eagle heritage and continuous homeland air-defense alert mission.
