Scania C42

     Notes: The C42-type semi-tractor actually comes in two versions: the T112E C42 with a forward-control tipper cab and a 430-horsepower engine, and the R142E C42 with a conventional cab and its 343-horsepower engine in a separate engine compartment under a hood.  Both are virtually identical in size and weight, and share the same frame, chassis, transmission (which is manual), suspension, and fifth wheel system.  They are both designed to tow a variety of different semi-trailers, but are primarily used to tow transporter trailers and ammunition trailers for artillery.  In both cases, the cabs are large and roomy, are equipped with heaters (with air conditioning optional), have four doors for personnel, and provide room for two crewmembers and four passengers, as well as their equipment.  Suspension is 6x4, and while the suspension is better than a road-only truck, it is not quite as robust as a true off-road suspension.

Scania R143EK

     Notes: This semi-tractor were procured by the Swedish Army in small numbers between 1990 and 1991.  It is primarily a tank-transporter semi-tractor, though it can tow other types of semi-trailers, and was designed specifically for military use.  The cab has two rows of seats, with a space behind the seats for crew and passenger equipment (to a certain point – the space is not large).  The cab is a forward control tipper cab with four doors and is heated.  Behind the cab are a spare tire rack and a pair of 20-ton-capacity winches with 40 meters of 24-millimeter cable.  The truck also comes with snatch blocks and a hydraulic jack should a tire need to be changed, as well as two spotlights and a rotating beacon.  The engine has a pre-heater and a fuel heater.  The suspension is 6x6 and is off-road capable.  It should be noted that while production for the Swedish Army continued only until 1991, the R143EK was then “civilianized” and placed on the regular market, with production continuing until 1996.  Civilian models have no winches and are generally more “luxurious”, and often have sleeper cabs in place of the second row of seats, but are otherwise similar. All are equipped with a DSC1403 450-horsepower diesel engine.

     A variant of the R143EK, the T143E, has a different cab – it uses a conventional-layout front end with the engine up front under a hood, the cab center (with either a short cab with one row of seats and two doors, two rows of seats with two doors, or, for civilian purposes, a sleeper cab).  The suspension of the T143E is 6x4 and primarily meant for the road.  Performance is similar to the R143EK.  The Swedish Army has a very few of these, but most construction was for civilian purposes.

     Twilight 2000 Notes: In a controversial move, most civilian R143EKs and T143Es were appropriated for military use early on – even those already in private ownership.

Scania T144GB6x4NZ530

     Notes: This semi-tractor was introduced in early 1997, with full-scale production starting in 1998.  They were designed specifically to tow a tank transporter, and especially ones carrying Sweden’s version of the Leopard 2 tank (Strv 121 and 122).  In 2000, they were introduced into Belgian service, and in 2003, to the French military.  Though all three countries use the same base semi-tractor, they tow different trailers in each country, and have different types of ancillary equipment.  The cab of the truck is sort of a sleeper cab; it has a curtain between the front and rear rows of seats, but the off-duty crewmember sleeps on the seat itself in the Swedish and French versions, which is also used for passengers (primarily the crew of the tank being transported).  Some of the Belgian cabs are also built like this, but some have genuine sleeper cabs with two bunks.  Belgian and French models also have optional air conditioning, heating, camouflage netting, a pair of rotating spotlights and beacons, and snow chains.  Swedish models have a heater as standard, as well as a blowtorch, an engine heater and pre-heater; options include camouflage netting, two spotlights, rotating beacons, and snow chains.  The truck has a forward engine compartment with a large hood and a central cab.  Behind the rear seat is a compartment for crew equipment.  The T144 is powered by a Scania DSC1413 Euro2-compliant diesel developing 530 horsepower, coupled with a Scania GRS900R 9-speed transmission.  Swedish trucks of this sort have a pair of 15.3-ton-capacity winches with 50 meters of 19mm cable; these winches have a remote control.  Belgian Army versions use two 20.4-ton-capacity winches with 45 meters of 7mm cable.  The suspension is 6x4 and designed primarily for road use.  Note that while 112 tons is the maximum the truck can tow, peacetime safety regulations usually limit this to 100 tons.

     Twilight 2000 Notes: This semi-tractor does not exist in the Twilight 2000 timeline.

Volvo FH16

     Notes: This semi-tractor was designed for extreme climatic conditions, whether very hot or very cold.  Currently the only military user is Israel, who uses it primarily for the transportation of semi-trailers carrying Merkava tanks.  The cab is that of the Volvo Globetrotter civilian semi-tractor, with a high-roofed forward control sleeper cab.  The cab can be air conditioned for hot climates, and a roof hatch of various sizes with or without a weapon mount is also an option.  (These are included in the stats below.) Behind the cab is a large stowage bin and a pair of 25-ton-capacity winches.  The suspension is 6x6, but designed primarily for road or dirt road use. The engine may be a D16A-520 developing 520 horsepower, a D16C-550 550-horsepower, or a D16C-610 610-horsepower diesel engine. These engines are electronically controlled and do not need a turbocharger to achieve their high power and torque ratings. The 520-horsepower engine is Euro2 compliant, while the other two engines are Euro3 compliant.

     Twilight 2000 Notes: the 550 and 610-horsepower versions do not exist in the Twilight 2000 timeline.

Volvo N12

     Notes: Developed from a civilian semi-tractor, the N12 was procured in 1977 specifically to pull tank transporter semi-trailers carrying Centurions or S-Tanks.  It is capable of towing other semi-trailers, however.  It is a conventional layout semi-tractor, with the engine in front, cab center, and the fifth wheel in the rear.  The cab has two rows of seats and is able to carry the crew of the tank being transported as well as the crew of the truck on two rows of seats.  The cab is heated.  The military N12 is powered by a TD120 turbodiesel engine developing 330 horsepower, and later, 385 horsepower.  An omission is a winch, but most of the transporter trailers Sweden uses do have winches of their own and a truck-mounted winch was judged unnecessary (at the time).  The suspension is 6x4 (the front wheels are not powered) with a reinforced frame, chassis, and suspension; though the suspension is not really designed for off-road use, it can deliver respectable off-road performance.  The N12 has a stowage bin as the rear of the cab for crew equipment and differential locks for the wheels.
