Usaf Grey — 5 museum-grade prints in this palette. Pilots and maintainers have called the F-16 the Viper since the 1980s — a nickname that stuck when the official Fighting Falcon name never quite matched squadron-bar banter. The F-16V Block 70 package adds an AESA radar, modern cockpit architecture, and structural upgrades that extend airframe life for operators from the U. The Fairchild Republic A-10 Thunderbolt II entered service in the 1970s as a dedicated tank-killer and forward-air-support platform, built around the seven-barrel GAU-8 Avenger 30 mm cannon — still the heaviest automatic cannon ever mounted on an aircraft. The A-10C modernization added digital glass cockpit and precision-guided munitions such as GBU-38 JDAM while preserving the Warthog's titanium-armoured bathtub cockpit and straight-wing slow-speed agility. The General Dynamics F-16 Fighting Falcon entered USAF service in the late 1970s as a lightweight day fighter that evolved into the world's most numerous fixed-wing combat aircraft, with pilots universally nicknaming it the Viper for its agile handling and Battlestar Galactica echo. The Block 30 introduced incremental avionics and engine options while retaining the type's signature frameless bubble canopy, side-stick flight controls, and cropped-delta wing.
