Well,................ I had an idea for IAW-II, but I'll never get around to it and I don't have a C-17 kit to start with.
I'm throwing this out for any interested, interesting Modeler.
The AKC-175 "Hound of Hell" heavy combat gunship. Based on the Boeing C-17 Globemaster III platform. 2 5" 45 caliber rapid fire cannon, GAU-8B 30mm rotary cannon, "Flicker" Real-time 1-petawatt thermal laser targeting system, with "Fire & Forget" capability. Mark your target once, no more loitering in hostile AAA and SAM environments, with TDS to update targeting and positioning data to other aircraft in the strike zone. "Flicker" also silently negates softer targets like radar antennas and electrical substations. High energy, digital ECM gear makes her invisible to everything but eyeballs.
"Azrael" (Israeli/Raytheon built) laser guided, missiles in AP, WP, and cluster munitions options. M2 Browning .50 caliber guns for smaller, surgical targets and close-in defense. Terrain following and GPS mapping capability to compare yesterdays topography to that of today. "Hmm. That wasn't there yesterday........" Limited air refueling capability for thirsty fighters that overstay their "bingo" on strike & SAR missions. Galley, Corpsman's station and 2 AIM-9M Sidewinder missiles on each wingtip for the enemy aircraft foolish enough to make a second pass. Essentially the biggest, deadliest Muther in the sky. The ground pounder's second best friend, besides the A-10 War Thog.
"Boeing. Making valuable stuff on the ground go 'BOOM!' for more than 100 Years."
Howzatt?!
