Topic: AT-APC Hovercraft
Background: Present day. Manufacturer Griffon Hovercraft (http://www.griffonhovercraft.com) is trying to develop a truly all-terrain vehicle. Current hovercrafts offer the advantage of being amphibious and able to travel over sea or land mines without danger but are limited to relatively flat surfaces. They want you to develop a hovercraft that is also suitable over more mountainous terrain.
Brief:
1. Design a hovercraft for use by the military as an armoured personnel carrier.
2. It must be able to deal with rougher terrain than current hovercrafts.

There are four disturb reactors and two adjustable ones. The intention is that in difficult obstacles the hovercraft would be able to save them with a powerful impulse.

The Military Fast Attack HoverCraft, was designed as a fairly quick strike vehicle. Carrying 5-8 personnel, not including the two necessary drivers. Two drivers are needed when not in auto mode, as the 4 exhaust thrusters, are independant and can be oriented in a wide range allowing diverse body movement for the vehicle. Although landing can be done on the body itself, the ring/grates attached to the thruster body, are there to protect the thrusters should the be landed on. they can support the weight. The failings of the the FAMHC that caused its lackluster sales and use, was in that there are so many moving motors/servos and struts, maintanence of the craft was not realistic.

The main issue with conventional hovercraft on rough terrain is that they operate on a cushion of air trapped within the skirt, if the craft gets titled over rough terrain it allows the air cushion to escape. The solution on the Hippo is to have 6 independent air cushions/skirts, each individually powered and articulated, allowing a constant level of lift over very rough terrain.
The Hippo has 3 crew, one driver front and center, an officer and a weapons specialist, 10 fully equipped troops can fit in the personnel compartment behind the drive cabin.
It is powered by 2 jet turbines with thrust vectoring to provide drive and steering.
Armament consists of twin Metalstorm electronically fired pods, forward firing only used to clear the embarkation area, and a triple barreled Metalstrom 40mm turret for general protection. It also has multiple grenade launchers and smoke generators.

Since hovercraft control like drunken air hocky pucks, i decided that the first thing you would need to do in order to boost the movement on rough terrain would be to add friction. The legs are not meant to lift the entire weight of the craft, but mearly to push off against or pull towards, much like a roller blader moving forward from one fling to the next. this would allow a crab like scuttling motion i would imagine. It also would allow upward torque for pushing the main frame of the craft up inclines and the like (nothing huge mind you). The feet could be bio mechanical, but i was going more for a fabric covered look.
I made this larger than most, it features a split frame design so the forward 'cockpit' is hinged with the rear. i would say around 20 marines could fit into this beast. Driving would either be done remotely, via AI or internal pilot using mini cameras.
Leg 'feet' could be switched for wheels or whatever depending on the mission by using the modular pod attachments.

The Land-Griffin ACV-IV is an extensive modification of the Griffin AVC-III, this vehicle is optimised for advanced terrain operation. Although it still retains its amphibious capabilities the Land-Griffin is only suitable inland or close to shore operation rather than the full ocean operation of AVC-III. Replacing its marine characteristics are improved dust exclusion, increased armour, better nap-of-earth flight technology and improved manoeuvrability even with a greater weight.
The vehicle is capable of transporting a squad 40 combat ready marines and their equipment or 14 marine and two light transport vehicles. The Land-Griffin is envisioned to operate in a medium combat lift role with sufficient fire power and armour to support troops as they go about their mission.
Four lifting fan and cushion units are mounted at the corners of the carrying body. Fan units are capable of independent rotation an elevation so that they may optimise coverage on uneven terrain. At the centre of the main body is a trio of large turbo-fans these are used for balancing the craft, providing extra thrust and giving sufficient lift for short 'jump' flights - the exit nozzles of these fans have thrust-vectoring fins for additional directional control.
Main propulsive drive is granted by two co-axial mounted paired turbo-jet engines, these are located on a pivoting base at the rear of the main body with a +/- 120 degree horizontal and +/- 45 degree vertical range of motion.
Armament is sufficient for the vehicle to defend itself and also act in a light to medium role giving fire support for disembarking troops when deploying into hostile LZs.
*Main armament is a pair of quad mounted 25mm chain guns for engaging light-medium vehicles, infantry and helicopters to a range of 1.5 km – both units are mounted on raised towers to give better axis of fire without exposing the vehicle.
*A 12mm gattling cannon is turret mounted bellow the command module for engaging light targets long path of travel.
*Four open gun positions on the vehicles flanks have multipurpose mounts for either heavy machineguns or grenade launchers.
*AA defence come from a dorsal mounted ground to air missile system.

The Griffon 1121 troop transport hovercraft is ideal for multi-terrain warfare. It's four, side-mounted turbines allow for increased lift-stability/steering at sea, while converting to hydrolic, shock absorbing wheels for land based missions. This quick conversion makes the 1121 unlike any other hovercraft, expanding maximum range for troop transport and artillery support. The 1121's surface is designed at angles for increased stealth and it's twin cannons, with a firing range of five miles, makes this craft a formidable foe in both sea and land campaigns. Max crew capacity: 50-60

The Griffon 'Millipede' APC transport is a next generation hovercraft designed to navigate a variety of challenging terrain. Each jointed segment is supported by a lift turbine that can be tilted to allow for forward and lateral movement. This allows for flexible navigation capabilities, as well as eliminating the need external drive blades or jet engines, which would be obvious targets for enemy fire. The millipede has two identical 'head' segments - fore and aft - that allow for immediate change of direction. On each are two defensive/offensive hardpoint weapon pods which have near 180 degree movement. Because the millipede is designed with components in mind, it can be customized to suit each mission. A typical configuration will be composed of fore and aft drive segments, a communications segment (picture here behind the forward drive component), and anywhere from 1-6 troop segments, which can carry up to 12 soldiers each. Each troop segment has two quick-drop assault ramps for rapid deployment of personnel. in development is a medical segment, which will bring state-of-the-art medical facilities to the frontlines.
