Control panel

MSV control panel This section of the control panel gives readings for radiation level, internal and external temperature and air contamination. The calibrated screen at the bottom shows the distance of the vehicle from atomic explosion.


MSV passenger compartment The passenger compartment has padded seats with safety straps and an intercom/exteernal TV with controls on the central arm. The TV screen faces the occupants. Over the seats, the air vents can be seen. In the event of gas or radiation, outside atmosphere is cut off and the vehicle operates its own pressurised atmosphere.

Shell construction

MSV shell Construction of the shell shown in section at the passenger cabin window. From the outside in the layers are armour plate, refrigeration honeycomb, radiation damping sandwich and internal steel wall. The window is of a special heat-resistant, anti-radiation lead quartz.


MSV rear engine The rear engine layout is slightly different. On each side of the centre line are four of the eight rotary diesel cylinders (1) which drive the generator (2). Current passes through the distributor box (3) to the electric motors (4) and links with the front electrics (5). Drive passes through the bevel box (6) and the universal jointed drive shaft (7) to the twin wheels (8). An interesting feature is that the diesel power can be transmitted to the wheels direct via a gearbox and the bevel box (6) should the electrics fail. In view of the great weight of the vehicle special breaking is needed. In addition to the discs (10) hydraulic breaking is used in the drum (9), fed from a pressurised cylinder (11), the fluid being cooled in the cooler (12) situated in the airstream from an intake just above the rear wheels. (13) is the fluid storage tank.


MSV brakes The hydraulic brakes work like a turbine in reverse. Blades rotate with the wheel in a specially shaped drum forcing the working fluid from the feed pipe into the collector pipe and compressing it at the same time. The result is a steady slowing of the wheels enabling the disc brakes to be brought into play when required. The bullet-proof tyres are tubeless and filled with self-sealing compound. If this should prove ineffective a secondary inner tube automatically inflates to maintain pressure.


MSV batteries The batteries (1) can be recharged by the solar collector strips (2) and used to drive the standby motor (3) linked to the main transverse diesel engine (4), which drive the wheels via the gearbox (5). Hydraulic damped link suspension (6) holds the twin wheels (8), which have power-assisted steering (7). Air intakes serving carburettors and driver's cabin are at (9) and headlights at (10).

description: Four seater, high-speed maximum-security vehicle, capable of an amazing 200 mph, 24 ft long, weighing 8 tons, bulletproof, hand-assembled vehicle boasting of being indestructible. It is even rumoured that one of the prototypes withstood the combined efforts of the World Army Air Force on the testing range for a whole week. Expertly fitted with radar and two-way radio and complete with a "survival food kit". Very much a combat vehicle, carrying a lethal load of ammunition. Specifically used for transporting Mysteron-threatened V.I.P.s in the utmost safety to their destinations.
