    Turkish F-16 and Greek Mirage 2000-5: As stated in the link the video isn't dated and neither of the two pilots were trying very hard apparently (3G on average with a peak at 5G). Still the video is nice in itself and quite clear. Video was published following 52 violation of Greek airspace by Turkish air force 2 days ago.

    A more aesthetic picture of my creation: I'm imagining shitty 90s toy commercial faux-rock playing in the background.

    I think my favorite part about this is the insane drivetrain used just to get reasonable ground pressure with wheels, when there is no explicit requirement in the solicitation to even use wheels.

    While waiting for the competitors to continue their work, I got bored and decided to produce a design at the other end of the scale: This is the Maxcat, an experimental heavy wheeled AFV which uses a rather insane hydraulic drive system which uses three engines to power the 14 individually-articulating road wheels (each provided with hydraulic motor). The drive system is a power hog, and requires the use of an elaborate hydraulic control system to make it all work. The final wrinkle is that the inner set of wheels need a complex geared torsion bar system to provide the correct amount of travel using stubby torsion bars. The results are impressive, however: the Maxcat sports a 120mm/L60 gun with the same ballistics as the pre-war M58 (including a useful APDS round based on the one used in the old British L1A2), and has impressive survivability thanks to the large distances between the outer hull and the major components. The hull front has respectable KE resistance (260-350mm RHA equivalent depending on the angle and the region targeted) and frankly insane CE resistance (well over 1000mm of RHA equivalent in some places). The turret front is actually less protected over all, but still manages up to 270mm/750mm KE/CE resistance depending on the angle and area hit. The brow armour is also notable, and gets around 300mm/>1000mm KE/CE resistance against attacks from the front. The Maxcat weighs in at just under 70st unloaded, and hits the minimum range requirement by dint of six massive fuel tanks with a maximum capacity of just over 1150 gal. It hits 90km/h on roads, and will try to do the same offroad if the driver is foolish enough to open the throttle. With all of the above, the Maxcat is designed to be an MBT in all but name - meant to take on all comers head-on and win. It would probably be an expensive, resource-devouring maintenance queen at base, but while out in the field it would be an unholy terror to anything foolish enough to get in its way.

    Greetings all, I've been pulled on as a judge for this one, so none of the following should be construed as competition so much as... encouragement. This is the Mogcat: It's designed to exactly nail the minimum specs, while being relatively easy to produce and long-legged. It sports a 3"/76mm main gun, a bunch of machineguns and the sort of conveniences you'd expect from a late-40s design (gunner's panoramic sight, wet ammo racks, internal firefighting equipment and smoke launchers). It's otherwise very bare-bones, and comes in at all of 10.3st/9.3mt. I'll add further specs as this goes along, but for the moment all you have to know is that this is the minimum, lowest bar that I can think of. This thing is intended to be the product of unimaginative minds working at what passes for the ordinance department in the Lone Free State - men who spent their lives designing incremental improvements on machineguns and recoilless guns, and think that their lightweight 3" gun is a world-beating novelty. For what it's worth; what I would like to see is something that grabs the requirements by the balls and works out a way to wring something that can beat @N-L-M's Norman design in a reasonably fair fight out of the thin gruel that the Provisional Government has put out. Remember that the Texans don't know what they don't know - their official line is that the arrival of Deseret light tanks is some sort of shocking revelation. But they aren't stupid - the smarter engineers will already be looking at what they could do with their given automotive and gun tech, and what was achieved in the pre-war era, and are probably staying up late at night worrying about their conclusions. Update 1: I had a think last night, and decided to swap out the turret crew to a commander-loader and gunner configuration instead of the T-34-esque commander-gunner and loader configuration (now included with the rest of the pictures). Here's a bonus picture of the vehicle in travel configuration - turret rearward and gun in cradle: Update 2: Here's some more stats on the vehicle, in the prescribed units... Description The Mogcat is a 6x6 armoured scout car designed for mobility and extended operations. The design boasts an innovative engine, drivetrain, suspension package and gun, all built with an eye to ruggedness and light weight. The Mogcat's 3-inch cannon is able to provide useful anti-armour (APHE and HEAT-FS) and anti-infantry (HE, canister and shrapnel shell) firepower, while the plethora of machineguns it sports allows it to tackle dismounted infantry and light vehicles with confidence. The combination of purpose-built drivetrain components, long operational range and firepower makes the Mogcat a strong contender for the present production contract. Major dimensions and mass Crew: 3 (driver, commander-loader, gunner) Length: 16'/9" (hull), 19"/4' (gun forward) Width: 6'/7"m Height: 9'/6"m (top of commander’s cupola) Unloaded weight: 8.7 ton Loaded weight: 10.3 ton Ground pressure: 4900lb/ft2 (unloaded, muddy ground) to 5785lb/ft2 (loaded, muddy ground) Axle loading: 3.4t/axle loaded Mobility Engine: 4-cylinder turbodiesel, 732cu displacement, 200-280HP PWR: 19.4HP/t loaded, detuned Ground clearance: 17.7" Max road speed: 60mph Max offroad speed: 20mph Operational range (on road/offroad): 850mi/500mi Protection Armour: 2" LOS on hull front (1" RHA @ 60°) 0.8" LOS on hull sides with 30° angle (0.8" RHA @ 90°, 0.5"mm @ 45°) 0.6" RHA on hull rear 0.5" LOS on hull bottom (0.4" RHA @ 45°) 2" LOS on turret front (1.8" RHA @ 30°) 2" CHA mantlet 0.8" LOS on turret sides with 30° angle (0.6" RHA @ 25°) 0.6" RHA on turret rear 0.4" RHA on roof 0.4" RHA on turret floor 2" RHA turret neck ring and splash guard 0.4" Aluminium turret basket, skeletonised 3.2" smoke dischargers (2 reloads). Fuel tanks on driver’s sides improve protection against threats from the front. Ammunition stowage in wet racks in turret bustle, turret floor and driver’s compartment. Internal fire control system (BCF canisters in engine compartment and fighting compartment, driver has access to removable CO2 extinguisher). Firepower Turret ring diameter: 4'/5" Main gun: 3" L/40 medium-pressure gun, 12" recoil travel Ammunition stowage: 50 rounds main gun ammunition stowage +30/-10 degree elevation. Ammunition: 3"x15.2" cartridge (3.7" base, 19lb max all-up weight) APHE: 13.9lb, 2425ft/s, 3.5" RHA penetration at 1000m HEAT-FS: 15.4lb, 2295ft/s, 9.8" penetration HE: 13.7lb (1.35lb fill), 2460ft/s, 0.4" RHA penetration APFSDS (spindle-type, 15L/D ratio, maraging steel penetrator): 1.5lb, 5900ft/s, 6.5" RHA penetration at 1000 yards. Secondary weapons: .30 cal coaxial MG (600 rnds) .30 cal gunner's MG (600 rnds) .50 cal commander’s MG (500 rnds) Additional features Long-range transistor radio. Vehicle intercom system. Ancillaries (fire tables, gunner’s quadrant, traverse markings etc) for indirect fire missions. Commander has access to panoramic sight (x1) and telescopic sight (x4) for target acquisition and lay-on. Turret traverse is electric (30 degrees per second rotation). Fume extractor on main gun Large hatches in hull rear allow easy servicing of engine and gearbox. Storage lockers in hull rear flanking the engine for personal/supplies stowage. Hydraulic jacks on the hull bottom between the first and second wheels and at the rear make changing tires easier. Update 3: I reworked all the images.
